• USB transfer speed for Windows 7 is incredibly slow to my external drive

  - by Wolfram

  I'm running Windows 7 Pro and am try to backup 116 GB of data to my external 1 TB hard drive. My laptop has only USB 2.0 ports and my hard drive is USB 3.0 compatible, as is the cable I'm using. I understand that the transfer speed should still be in accordance with USB 2.0 speeds. However, right now I'm getting 135 KB/s and it's been gradually dropping. For an earlier transfer, I would get between 4 MB/s to 8 MB/s. So, I'm really just wondering what's going on with my transfer rate and what I can do to improve it. I'm currently about 35 GB into the 116 GB transfer. Another strange thing is that the window which shows the transfer status decided to max out at 835 MB, and therefore shows items remaining as 0. However, it is still performing the rest of the transfer, and I can see it still cycling through files. Now that I think about it, it seems plausible that the speed being shown by the window is calculated merely as total data transferred / time elapsed. Since the "counter" of data, as far as what is being displayed in the window, maxed out at 835 MB, as time increases, the speed shown is going to keep decreasing because the 'total data transferred' value isn't being incremented. So with that in mind, I suppose I don't actually know at what rate the data is being transferred currently. Nonetheless, my best speed earlier was only around 8 MB/s. Shouldn't USB 2.0 deliver closer to 35 MB/s? Also, if someone can tell me why the transfer status window is displaying the incorrect data information and how to fix this, that would also be appreciated.

• When clientTransferProhibited is off to transfer a domain name, couldn't the name be stolen?

  - by Cedric Martin

  I'd like to transfer a domain from one registrar (Key-systems) to another registrar (OVH). I don't really understand the procedure and I'm a bit confused... I read everywhere that clientTransferProhibited prevents people from stealing your domain name. Now apparently during the course of transferring my domain from Key-systems to OVH, I'll to change clientTransferProhibited so that the transfer is allowed. Wouldn't my domain then become "stealable" during some amount of time? (a few hours / days / week)

• Windows 7 Easy Transfer does not start (Windows XP)

  - by Gerhard Weiss

  Windows 7 Easy Transfer does not start on my Windows XP system. I installed Windows 7 Easy Transfer and when I click to start it nothing happens. Not even an error message. I uninstalled and reinstalled a few times with the same results. I even tried starting it from C:\Program Files\Windows Easy Transfer 7\migwiz.exe with the same results. Nothing happens! Any one else run into this issue? Any suggestions on how to start it up differently? This is my work system so I do not know if they have it locked down. This is a Windows XP, Dell OptiPlex755 built about 3 years ago. I downloaded the 32-bit from this website: http://windows.microsoft.com/en-us/windows7/products/features/windows-easy-transfer and yes my system is 32-bit ;)

• Low USB transfer speed

  - by dhasu

  Hello, I am using Windows Vista, my Motherboard is Intel D102GGC2 The transfer speed through USB is very slow on my PC, just 2-3 MBps... I also use Ubuntu 9.10, and surprisingly the USB transfer speed is as expected, ie 16-17 MBps. So everytime i have to transfer Huge files i have to reboot into Ubuntu. What might be the Problem ??? I checked the Intel website for the ubdated drivers for my mobo, but they dont support my mobo now. Thanks

• Closer look at the SOA 12c Feature: Oracle Managed File Transfer

  - by Tshepo Madigage-Oracle

  The rapid growth of cloud-based applications in the enterprise, combined with organizations' desire to integrate applications with mobile technologies, is dramatically increasing application integration complexity. To meet this challenge, Oracle introduced Oracle SOA Suite 12c, the latest version of the industry's most complete and unified application integration and SOA solution. With simplified cloud, mobile, on-premises, and Internet of Things (IoT) integration capabilities, all within a single platform, Oracle SOA Suite 12c helps organizations speed time to integration, improve productivity, and lower TCO. To extend its B2B solution capabilities with Oracle SOA Suite 12c, Oracle unveiled Oracle Managed File Transfer, an integrated solution that enables organizations to virtually eliminate file transfer complexities. This allows customers to load data securely into Oracle Cloud applications as well as third-party cloud or partner applications. Oracle Managed File Transfer (Oracle MFT) enables secure file exchange and management with internal departments and external partners. It protects against inadvertent access to unsecured files at every step in the end-to-end transfer of files. It is easy to use especially for non technical staff so you can leverage more resources to manage the transfer of files. The extensive reporting capabilities allow you to get quick status of a file transfer and resubmit it as required. You can protect data in your DMZ by using the SSH/FTP reverse proxy. Oracle Managed File Transfer can help integrate applications by transferring files between them in complex use case patterns. Standalone: Transferring files on its own using embedded FTP and sFTP servers and the file systems to which it has access. SOA Integration: a SOA application can be the source or target of a transfer. A SOA application can also be the common endpoint for the target of one transfer and the source of another. B2B Integration: B2B application can be the source or target of a transfer. A B2B application can also be the common endpoint for the target of one transfer and the source of another. Healthcare Integration:  Healthcare application can be the source or target of a transfer. A Healthcare application can also be the common endpoint for the target of one transfer and the source of another. Oracle Service Bus (OSB) integration: OMT can integrate with Oracle Service Bus web service interfaces. OSB interface can be the source or target of a transfer. An Oracle Service Bus interface can also be the common endpoint for the target of one transfer and the source of another. Hybrid Integration: can be one participant in a web of data transfers that includes multiple application types. Oracle Managed File Transfers has four user roles: file handlers, designers, monitors, and administrators. File Handlers: - Copy files to file transfer staging areas, which are called sources. - Retrieve files from file transfer destinations, which are called targets. Designers: - Create, read, update and delete file transfer sources. - Create, read, update and delete file transfer targets. - Create, read, update and delete transfers, which link sources and targets in complete file delivery flows. - Deploy and test transfers. Monitors: - Use the Dashboard and reports to ensure that transfer instances are successful. - Pause and resume lengthy transfers. - Troubleshoot errors and resubmit transfers. - View artifact deployment details and history. - View artifact dependence relationships. - Enable and disable sources, targets, and transfers. - Undeploy sources, targets, and transfers. - Start and stop embedded FTP and sFTP servers. Administrators: - All file handler tasks - All designer tasks - All monitor tasks - Add other users and determine their roles - Configure user directory permissions - Configure the Oracle Managed File Transfer server - Configure embedded FTP and sFTP servers, including security - Configure B2B and Healthcare domains - Back up and restore the Oracle Managed File Transfer configuration - Purge transferred files and instance data - Archive and restore instance data and payloads - Import and export metadata You will find all the related information about SOA 12.1.3.

• Does a site's bounce rate influence Google rankings?

  - by Joel Spolsky

  Does Google consider bounce rate or something similar in ranking sites? Background: here at Stack Exchange we noticed that the latest Google algorithm changes resulted in about a 20% dip in traffic to Server Fault (and a much smaller dip in traffic to Super User). Stack Overflow traffic was not affected. There was an article on WebProNews which hypothesized that bounce rate might be a ranking signal in Google's latest Panda update. According to Google Analytics, these are our bounce rates over the last month: Site Bounce Rate Avg Time on Site ------------- ----------- ---------------- SuperUser 84.67% 01:16 ServerFault 83.76% 00:53 Stack Overflow 63.63% 04:12 Now, technically, Google has no way to know the bounce rate. If you go to Google, search for something, and click on the first result, Google can't tell the difference between: a user who turns off their computer a user who goes to a completely different web site a user who spends hours clicking around on the website they landed on What Google does know is how long it takes the user to come back to Google and do another search. According to the book In The Plex (page 47), Google distinguishes between what they call "short clicks" and "long clicks": A short click is a search where the user quickly comes back to Google and does another search. Google interprets this as a signal that the first search results were unsatisfactory. A long click is a search where the user doesn't search again for a long time. The book says that Google uses this information internally, to judge the quality of their own algorithms. It also said that short click data in which someone retypes a slight variation of the search is used to fuel the "Did you mean...?" spell checking algorithm. So, my hypothesis is that Google has recently decided to use long click rates as a signal of a high quality site. Does anyone have any evidence of this? Have you seen any high-bounce-rate sites which lost traffic (or vice-versa)?

• Dlink DWA-556 Access point fails to start on 2.6.35-25 while 2.6.35-24 works. How can I do this with >2.6.35-24?

• Understanding the maximum hit-rate supported by a web-server

  - by SNag

  I would like to crawl a publicly available site (and one that's legal to crawl) for a personal project. From a brief trial of the crawler, I gathered that my program hits the server with a new HTTPRequest 8 times in a second. At this rate, as per my estimate, to obtain the full set of data I need about 60 full days of crawling. While the site is legal to crawl, I understand it can still be unethical to crawl at a rate that causes inconvenience to the regular traffic on the site. What I'd like to understand here is -- how high is 8 hits per second to the server I'm crawling? Could I possibly do 4 times that (by running 4 instances of my crawler in parallel) to bring the total effort down to just 15 days instead of 60? How do you find the maximum hit-rate a web-server supports? What would be the theoretical (and ethical) upper-limit for the crawl-rate so as to not adversely affect the server's routine traffic?

• PC to USB transfer slow

  - by Vipin Ms

  I'm having trouble with USB transfer,not with external hard disk. Transfer starts with like, for the transfer of 700MB file it starts with 30mb/s and towards the end it stops at 0s and stays put for like 3-4 mins to transfer the last bit. I have tried different USB devices, but no luck. Is it a bug? Another important point is, in Kubuntu there is no such issue. So is it something related to Gnome? I'm using Ubuntu 11.10 64bit. Somebody please help, it's really annoying. Here are the details. PC all of my drives are in ext4. USB I tried ext3,ntfs and fat32. All having the same problem.

• Why Standards Place Limits on Data Transfer Rates?

  - by Mehrdad

  This is a rather general question about hardware and standards in general: Why do they place limits on data transfer rates, and disallow manufacturers from exceeding those rates? (E.g. 100 Mbit/s for Wireless G, 150 Mbit/s for Wireless N, ...) Why not allow for some sort of handshake protocol, whereby the devices being connected agree upon the maximum throughput that they each support, and use that value instead? Why does there have to be a hard-coded limit, which would require a new standard for every single improvement to a data rate?

• A bounce-rate attack to manipulate SEO ?

  - by Denis Volovik

  This is a question to experienced people that might help us shed some light on the issue. We noticed a very strange behavior on our site, in Google Analytics. Some dude from Finland, namely, from Kouvola city is hitting one of our pages - only one page on our site, 'bout a hundred times per day, all with an average bounce rate of 90%+... This is causing our overall bounce rate to go up by 1 to 3% per day... which is very disturbing.. since we're trying to do our best in order to keep it as low as possible. And obviously having it jumped from ~24% to 27%, just because of that crazy dude is not making us happy at all... We tried implementing a geo-targeted script in order to catch this particular visitor and deliver him a juicy message, and it seemed like it helped in the beginning, it has stopped for a day or two, but now he's back... The geo-targeted script was also logging all IP addresses for page requests originating from Finland in order to find out more details and (in order to block them on the server level, later).. but thing is, it was all mainly cable or DSL connections with various, but not constantly repeating IPs... we are all wondering what is he up to really ? I think that this page should be kept updated with ideas on how to combat this and perhaps someone could also shed light on what it might be ? What is the reason for doing this "bounce-rate attack", as I call it? There was a similar question asked on stackoverflow earlier, with no meaningful answer - here - How to stop bounce rate manipulation.

• Transfer websites and domains to new server

  - by Albert

  We have currently around 40 websites and 80+ domains/sub-domains in a shared 1&1 hosting package, and we just acquired a managed dedicated server with 1&1 as well. Now it's time to start transferring everything over to the new server. Transferring just the websites and databases wouldn't be a problem, it would take time but it's pretty straight forward. The problem comes when transferring the domains, let me explain why. Many of the websites we have are accessible via sub-domains of a parent domain. Ideally, we would like to transfer the sites one by one, in order to check for each one that everything works fine in the new server. However, since we also need to transfer the domain so it's managed in the new server, once we do that means that all the websites using that domain need to be already in the new server before transferring that domain, thus not allowing the "one by one" philosophy. Another issue is the downtime when transferring the domain, from the moment it stops working in the hosting package and becomes active in the new server. I believe there's nothing we can do here. So my question is if there's any way we can do the "one by one" transferring of the websites (and their corresponding sub-domains) in the circumstances described above. One idea I had would be: 1. Let's say we have website A, which is accessible using subdomain.mydomain.com (and there are many other websites accessible via other sub-domains of mydomain.com) 2. Transfer the files of website A to the new server 3. Point a test domain in the new server to the website A's folder (the new server comes with a "test" domain) 4. Test if website A works with that "test" domain 5. In the old hosting, somehow point the real sub-domain (subdomain.mydomain.com) to the new location of website A, in a way that user always see the same URL as always 6. Repeat 2-5 for every website belonging to the same domain 7. Once all are working in the new server, do the actual transfer of the domain to the new server, and then re-create all the sub-domains and point them to their corresponding website That way, users wouldn't notice that there's been a change (except for a small down time of the websites when doing the domain transfer). The part I'm not sure about is point 5 of the above. Is there any way to do that? I mean do it in a way that users see the original domain all the time in their browser, even for internal pages (so not only for the "home page", which would be sub-domain.mydomain.com, but also for example for the contact page, which would be sub-domain.mydomain.com/contact.php). Is there any way to do this? Or are we SOL and we're going to have to transfer all at the same time?

• Tried verything - Yet highest Bounce Rate?

  - by Sam

  I read a lot of blogs and tips articles on how to decrease bounce rate. I feel I write very good content (niche is science) and I setup a good design, with attractive features (like download as PDF etc.), increased site loading times (google page speed score is 80+) but even then my bounce rate is always above 90, sometimes 100 :(. I get 42% traffic from the US and google analytics reports no visitor staying for more than 10-12 seconds. Please guide me.

• How can I electronically transfer money to another account using Bank Transfer (BACS)

  - by Mooktakim Ahmed

  I'm working on a project where we collect payments from users using credit/debit/PayPal payments. The service is taking payments from users on behalf of a 3rd party organisation. Once we take the payment, minus fees, we want to transfer the amount to the organisations bank account. For now, what we can do is pay the organisation using Online Banking BACS bank transfer. But I would like to know if there is a way to do this automatically using an API. If we need to somehow register the 3rd parties bank account details before making transfers, this is fine. We just want to automate the whole process, since at the moment the transfer is a manual step. Are there any gateways or APIs I can use for this? In the UK?

• Transfer page from internal to external

  - by Theo Gulland

  Afternoon all! Currently I have a website with a list of audio products (essentially a search engine for audio deals). http://www.soundplaza.co.uk Once you go to the details page, you can then press the 'view deal' button to go to providers site e.g. = http://www.soundplaza.co.uk/all-deals/113/bookshelf-speakers/acoustic-energy-1 This jump between two sites is a bit harsh and I would like to show a transition page, to simply ease them into another site and not scare them off. Within this tradition page I will have a simple loading gif and some graphics showing that your transferring. QUESTION: What is the best way to send the details (link, product name etc) to this transfer page, to then wait 5 seconds, to then move on to the desired link... this can in NO WAY damage my SEO, if anything rel="nofollow" would be great if possible. Currently I have seen that you can submit form to the transition page, then you can use php sleep and then php header to transfer... however I am not sure if php header will transfer SEO value tot he provider? Any opinions would be great! Thanks

• Transfer files using java

  - by markovuksanovic

  I need to transfer lots of small files to a remote computer within my java program. I was wondering if somebody could suggest the best way to do so... I need to transfer lots of small files and it has to be really fast. Should I use some existing protocol implementation? maybe ftp? One important thing is that most files would be the same all the time, or the difference would be minor so I was thinking of using git for that purpose. Does anyone have experience with sth like this?

• Low "time on site" and high bounce-rate in Japan

  - by Noam

  I'm seeing a substantially low "time on site" and high bounce rate from visitors coming from Japan. Comparing to other states, even in languages I don't speak, the stats are still dramatically worse. So I assume there's something specific to that nation, that I should understand in order to make their experience better. The content they are seeing is in Japanese, and I've also translated the head-lines, which to my surprise didn't make stats look better. The site doesn't have a mobile version, so I assume that might be part of the problem. Wanted to hear from your experience what other reasons might there be that are specific for Japan. UPDATE: The content itself was in Japanese all the time, that's the reason it attracts users from Japan. The head-lines were in English, so I only changed them.

• Constructive criticism for my bounce rate being so high [closed]

  - by Daniel

  The bounce rate on my website's product pages is 80%, which is terrible. Could you offer any opinions on whether you consider the user experience to be bad, and how I could possibly improve it? Other pages, such as the home and category pages, have acceptable bounce rates, but the vast majority of my traffic lands on the product pages. I already tried removing some Google ads for a couple of days, but this didn't seem to help at all. I'm working on doing A/B testing at the moment. (It's tricky, as the site is based on a CMS - I custom coded the [Joomla] component, so hopefully I can get this testing working.)

• Purchase existing domain and transfer to new registrar

  - by Kiefer

  I am purchasing an existing domain from the owner who has it registered with GoDaddy. I want to transfer the domain to another registrar and of course have it under my name. If they update the registrant info to my name then it will lock down for 60 days. That's no good. If they simply transfer it to my registrar, how will they update the registrant info? I know about escrow services, but I don't feel I need one because I trust the seller and the amount is (relatively) small. Advice? Thanks!

• My rhythm game runs choppy even with high frame rate

  - by felipedrl

  I'm coding a rhythm game and the game runs smoothly with uncapped fps. But when I try to cap it around 60 the game updates in little chunks, like hiccups, as if it was skipping frames or at a very low frame rate. The reason I need to cap frame rate is because in some computers I tested, the fps varies a lot (from ~80 - ~250 fps) and those drops are noticeable and degrade response time. Since this is a rhythm game this is very important. This issue is driving me crazy. I've spent a few weeks already on it and still can't figure out the problem. I hope someone more experienced than me could shed some light on it. I'll try to put here all the hints I've tried along with two pseudo codes for game loops I tried, so I apologize if this post gets too lengthy. 1st GameLoop: const uint UPDATE_SKIP = 1000 / 60; uint nextGameTick = SDL_GetTicks(); while(isNotDone) { // only false when a QUIT event is generated! if (processEvents()) { if (SDL_GetTicks() > nextGameTick) { update(UPDATE_SKIP); render(); nextGameTick += UPDATE_SKIP; } } } 2nd Game Loop: const uint UPDATE_SKIP = 1000 / 60; while (isNotDone) { LARGE_INTEGER startTime; QueryPerformanceCounter(&startTime); // process events will return false in case of a QUIT event processed if (processEvents()) { update(frameTime); render(); } LARGE_INTEGER endTime; do { QueryPerformanceCounter(&endTime); frameTime = static_cast<uint>((endTime.QuadPart - startTime.QuadPart) * 1000.0 / frequency.QuadPart); } while (frameTime < UPDATE_SKIP); } [1] At first I thought it was a timer resolution problem. I was using SDL_GetTicks, but even when I switched to QueryPerformanceCounter, supposedly less granular, I saw no difference. [2] Then I thought it could be due to a rounding error in my position computation and since game updates are smaller in high FPS that would be less noticeable. Indeed there is an small error, but from my tests I realized that it is not enough to produce the position jumps I'm getting. Also, another intriguing factor is that if I enable vsync I'll get smooth updates @60fps regardless frame cap code. So why not rely on vsync? Because some computers can force a disable on gfx card config. [3] I started printing the maximum and minimum frame time measured in 1sec span, in the hope that every a few frames one would take a long time but still not enough to drop my fps computation. It turns out that, with frame cap code I always get frame times in the range of [16, 18]ms, and still, the game "does not moves like jagger". [4] My process' priority is set to HIGH (Windows doesn't allow me to set REALTIME for some reason). As far as I know there is only one thread running along with the game (a sound callback, which I really don't have access to it). I'm using AudiereLib. I then disabled Audiere by removing it from the project and still got the issue. Maybe there are some others threads running and one of them is taking too long to come back right in between when I measured frame times, I don't know. Is there a way to know which threads are attached to my process? [5] There are some dynamic data being created during game run. But It is a little bit hard to remove it to test. Maybe I'll have to try harder this one. Well, as I told you I really don't know what to try next. Anything, I mean, anything would be of great help. What bugs me more is why at 60fps & vsync enabled I get an smooth update and at 60fps & no vsync I don't. Is there a way to implement software vsync? I mean, query display sync info? Thanks in advance. I appreciate the ones that got this far and yet again I apologize for the long post. Best Regards from a fellow coder.

• My application's bounce rate jumped from 30% to 80% overnight

  - by davidrac

  My application is provided as a service that is embedded in other sites. I have google analytics installed on the login popup dialog which is a page of my application, which is opened from the host site (OAuth). About a week ago, I've noticed a sharp decrease in the number of new users registrations and a jump in the bounce rate (from ~30% to ~80%). This happened without any change in the application. I looked into technical parameters like page load time and error rates, but could not see any change in there. Any ideas what can cause this behavior?

• FFmpeg extract clip - stream frame rate differs from container frame rate (x264, aac)

  - by fideli

  Summary H.264 video seems to have a really high frame rate that requires a scaling factor to the applied to the duration of video that I'm trying to extract (900x lower). Body I'm trying to extract a clip from a movie that I have in MP4 format (created using Handbrake). After trying mencoder and VLC, I decided to give FFmpeg a shot since it was the least troublesome when it came to copying the codecs. That is, compared to mencoder and VLC, the resulting file was still playable in QuickTime (I know about Perian, etc, I'm just trying to learn how all this works). Anyway, my command was as follows: ffmpeg -ss 01:15:51 -t 00:05:59 -i outofsight.mp4 \ -acodec copy -vcodec copy clip.mp4 During the copy, The following comes up: Seems stream 0 codec frame rate differs from container frame rate: 45000.00 (45000/1) -> 25.00 (25/1) Input #0, mov,mp4,m4a,3gp,3g2,mj2, from outofsight.mp4': Duration: 01:57:42.10, start: 0.000000, bitrate: 830 kb/s Stream #0.0(und): Video: h264, yuv420p, 720x384, 25 tbr, 22500 tbn, 45k tbc Stream #0.1(eng): Audio: aac, 48000 Hz, stereo, s16 Output #0, mp4, to 'out.mp4': Stream #0.0(und): Video: libx264, yuv420p, 720x384, q=2-31, 90k tbn, 22500 tbc Stream #0.1(eng): Audio: libfaac, 48000 Hz, stereo, s16 Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Press [q] to stop encoding frame= 2591 fps=2349 q=-1.0 size= 8144kB time=101.60 bitrate= 656.7kbits/s … Instead of a 5:59 duration clip, I get the entire rest of the movie. So, to test this, I ran the ffmpeg command with -t 00:00:01. What I got was exactly a 15:00 minute clip. So I did some black box engineering and decided to scale my -t option by calculating what value to enter given that 1 second was interpreted as 900 s. For my desired 359 s clip, I calculated 0.399 s and so my ffmpeg command became: ffmpeg -ss 01:15.51 -t 00:00:00.399 -i outofsight.mp4 \ -acodec copy -vcodec copy clip.mp4 This works, but I have no idea why the duration is scaled by 900. Investigating further, each ffmpeg run has the line: Seems stream 0 codec frame rate differs from container frame rate: 45000.00 (45000/1) -> 25.00 (25/1) 45000/25 = 1800. Must be a relation somewhere. Somehow, the obscenely high frame rate is causing issues with the timing. How is that frame rate so high? The best part about this is that the resulting clip.mp4 has the exact same feature (due to the copied video codec), and taking further clips from this needs the same scaling for the -t duration option. Therefore, I've made it available for anyone willing to check this out.

Anyway, my command was as follows: ffmpeg -ss 01:15:51 -t 00:05:59 -i outofsight.mp4 \ -acodec copy -vcodec copy clip.mp4 During the copy, The following comes up: Seems stream 0 codec frame rate differs from container frame rate: 45000.00 (45000/1) -> 25.00 (25/1) Input #0, mov,mp4,m4a,3gp,3g2,mj2, from outofsight.mp4': Duration: 01:57:42.10, start: 0.000000, bitrate: 830 kb/s Stream #0.0(und): Video: h264, yuv420p, 720x384, 25 tbr, 22500 tbn, 45k tbc Stream #0.1(eng): Audio: aac, 48000 Hz, stereo, s16 Output #0, mp4, to 'out.mp4': Stream #0.0(und): Video: libx264, yuv420p, 720x384, q=2-31, 90k tbn, 22500 tbc Stream #0.1(eng): Audio: libfaac, 48000 Hz, stereo, s16 Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Press [q] to stop encoding frame= 2591 fps=2349 q=-1.0 size= 8144kB time=101.60 bitrate= 656.7kbits/s … Instead of a 5:59 duration clip, I get the entire rest of the movie. So, to test this, I ran the ffmpeg command with -t 00:00:01. What I got was exactly a 15:00 minute clip. So I did some black box engineering and decided to scale my -t option by calculating what value to enter given that 1 second was interpreted as 900 s. For my desired 359 s clip, I calculated 0.399 s and so my ffmpeg command became: ffmpeg -ss 01:15.51 -t 00:00:00.399 -i outofsight.mp4 \ -acodec copy -vcodec copy clip.mp4 This works, but I have no idea why the duration is scaled by 900. Investigating further, each ffmpeg run has the line: Seems stream 0 codec frame rate differs from container frame rate: 45000.00 (45000/1) -> 25.00 (25/1) 45000/25 = 1800. Must be a relation somewhere. Somehow, the obscenely high frame rate is causing issues with the timing. How is that frame rate so high? The best part about this is that the resulting clip.mp4 has the exact same feature (due to the copied video codec), and taking further clips from this needs the same scaling for the -t duration option. Therefore, I've made it available for anyone willing to check this out.
