  • Mass editing videos on Ubuntu?

    - by rick
    Hi, I'm trying to add a watermark and a credits image to all of my old videos. I downloaded them off YouTube so they are all flv (H.264?). Is there some software that will allow me do simple edits in batches? I know a little bit of Python and tried looking at some of the library but they all seem like overkill (and way above my head). So is there a solution besides getting some software and going through all my videos and doing it manually? They are all mostly the same length, but it would be nice to specify a relative position for my credits. e.g. show a static image for 10 seconds when the video is at 95%

  • ffmpeg: Could not find codec parameters for stream 0 (Video: h264) unspecified size

    - by dempap
    I try to convert a video from .raw to .mp4. For this reason I did download, build and install both x264 and ffmpeg. However, command: ffmpeg -f h264 -i output.raw -vcodec copy output.mp4 fails with error (shown in picture below). Is there any way to fix this? Commands I also run: 1 root@beagleboard:/# v4l2-ctl --list-formats ioctl: VIDIOC_ENUM_FMT Index : 0 Type : Video Capture Pixel Format: 'YUYV' Name : YUV 4:2:2 (YUYV) Index : 1 Type : Video Capture Pixel Format: 'MJPG' (compressed) Name : MJPEG 2 root@beagleboard:/dev# v4l2-ctl --set-fmt-video=pixelformat=0

  • How can I fix Problems with interlaced video jerking/flicking when playedback on DVD players? (Mixin

    - by Simon P Stevens
    I'm trying to make a DVD and the final DVD jerks when played on standalone DVD players. It seems to play fine on PCs. I think the problem may be to do with interlacing settings when rendering the final output, but I'll outline the whole editing process I have followed in case I've made a mistake somewhere else. Most of the footage comes from a sony handy cam (one of those mini DVD ones) so isn't great quality. It was set to "high quality" (haha) and 16:9 aspect ratio when it was recorded. I copy the files directly from the mini DVDs onto the hard drive and import them into Cinelerra. In Cinelerra I set the format to 25fps, 720x576, RGBA-8bit, 16:9, interlaced bottom fields first. When I've finished the editing, I add a Fields to frames effect (set to bottom first) to each video track. I render to audio and video separately: Audio: AC3, 128kbps Video: YUV4MPEG steam, video pipe settings: ffmpeg -f yuv4mpegpipe -i - -y -target dvd -flags +ilme+ildct mpeg2video % Cinelerra often crashes during the rendering, so I set it to generate a new video file at each label, and combine them using cat when I've got a sucesful render of each one. Once I've combined them, I use mencoder to re-index them: mencoder -forceidx -oac copy -ovc copy merged.m2v -o mergedReIndexed.m2v I combine the audio and video files using ffmpeg: ffmpeg -i AudioFile.ac3 -i VideoFile.m2v -target dvd -flags +ilme+ildct FinalMovie.mpg Then I build the menus with spumux and I create the DVD file system with dvdauthor, and finally I write it do a dvd-r like this: nice -n -20 growisofs -dvd-compat -speed=2 -Z /dev/dvd -dvd-video -V VIDEO ./ && eject /dev/dvd Originally, when I did it the DVD flickered badly, so as suggested in a guide I added the fields to frames effect in cinelerra. Now it doesn't "flicker", but has become "jerky" when there is lots of motion, particularly when the camera is moving, so the whole background moves. This is what I've tried so far: Removed "mpeg2video" from cinelerra video render pipe. Removed +ilme from render pipe. Removed +ildct from render pipe. Removed +ilme from render audio/video rejoin command. Removed +ildct from render audio/video rejoin command. Added -alt to render pipe. Added -alt to render audio/video rejoin command. Tried with and without the frames to fields effect in Cinelerra. and various combinations of the above. I've also tried this: change the Cinelerra fps to 50, use fields to frames (instead of frames to fields), render to an intermediate QTforlinux jpeg video stream, re-importing that back into Cinelerra, adding a frames to fields effect and then rendering that output as normal (@25fps), and I still have the same problem. Has anyone experienced this "jerking" playback before? Can anyone give any suggestions on how to fix it? (Like I say, it plays back fine on a PC, but not on any of the standalone players I've tried)

  • Add keyframes to a stream (FLV from RTMP)

    - by acidzombie24
    I downloaded a RTMP stream to my desktop. It uses the FLV (Flash) video codec. I do not want to reprocess/transcode/whatever to this video. VirtualDub can delete sections of video and since it's not encoding again the quality is the same and the filesize shrinks. I want to do something similar but instead add keyframes and not encode. What can I use?

  • How to stream H264 Video from camera over FTP?

    - by Jay
    I bought a h264 security camera system last year and set it up to ftp video to my computer. I was able to get the video to play (even though it played a little fast) on Ubuntu 11.04 using mplayer. A few months ago, I did a fresh install of 12.04 and I cannot seem to get the video to play with mplayer, smplayer or VLC. I have the restricted formats video packages installed and when playing with any of the players, all I get is a gray video. When calling mplayer from the command line to play the video with no options, I get a lot of these errors: [h264 @ 0x7f278c61f280]concealing 1320 DC, 1320 AC, 1320 MV errors No pts value from demuxer to use for frame! pts after filters MISSING I'm not a video expert and have been coming up with a lot of dead ends when Googling for this. Could someone offer some advice about how to play these videos?

  • How to use mencoder to speed up video ?

    - by timday
    There's a webcam streaming WMV video that I can play/record with mplayer/mencoder (Debian Lenny including Debian-multimedia) just fine. I'd like to capture the video such that, when played back, it's faster (so say 100s of real time zooms past in every 1s of video). The "frameskip" filter seems like it ought to do this, but when I try e.g mencoder -o output.avi -ofps 25 -vf framestep=100 -ovc lavc -lavcopts vcodec=mpeg4:... <mms source URL> what I actually get is something which plays for the same length of time as it's allowed to capture for, but which only updates the displayed image every 4 seconds. Is there any way mencoder can be persuaded to do what I want ? (By the way, ideally I'd like to average the frames together to obtain motion-blur instead of just dropping/discarding most of them.).

  • Extracting streaming video from swf

    - by user1018733
    I am trying to speed up this video by 1.25x to 1.5x, udacity style. I tried grabbing the http://smart.if.uidaho.edu/courses/f2012/cs512/ using the Download Flash & Video Firefox plugin, but it only grabbed the swf player that streams the video. Is there any other way to download this video? (as well as future videos). As a final solution, I can use video capture software while I'm not using the computer, but I don't want that hassle and time delay if possible.

  • FFmpeg convert video w/ dropped frames, out of sync

    - by preahkumpii
    I recorded a video using Bandicam with the MJPEG encoder to get the least amount of lag. Now, I am trying to convert that massive file to a h264 avi using ffmpeg. I know there are dropped frames in the video stream...more than 100 in the first two minutes, which I assume is simply because Bandicam dropped some when it couldn't keep up. So, when I convert the file to h264, the video and audio are out of sync, and appear to be more and more out of sync as output video progresses. Here is my basic command in ffmpeg: ffmpeg -i "C:\...\input.avi" -vcodec libx264 -q 5 -acodec libmp3lame -ar 44100 -ac 2 -b:a 128k "C:\...\output.avi" I have tried EVERYTHING I can think of including: -itsoffset [-]00:00:01 Tried this before and after input file. This doesn't work because as the video progresses it becomes more and more out of sync. -async 1 Doesn't work. -vsync 1 Doesn't work, but it does show dropped frames being duplicated. Two inputs of same file with mapping using -map 0:0 -map 1:1. Doesn't work. The source plays just fine. Any ideas how to convert it with ffmpeg and keep the audio and video synced? Thanks.

  • how to get adobe flash fullscreen video fluid with an atom processor?

    - by Antoine Rodriguez
    My system has an atom N270 + intel i915 graphic card. Under Windows I can enjoy 720p bigbuckbunny youtube video fullscreen without any trouble. Under Ubuntu 12.04 I have laggy and choppy fullscreen video and choppy video when not fullscreen. I've seen that under ubuntu the cpu is almost always at 100% use. What I must do in order to have videos playing well under ubuntu ? I've already tried the following : Force flash gpu detection : (no result) : mkdir /etc/adobe echo "OverrideGPUValidation = 1" | sudo tee -a /etc/adobe/mms.cfg grub options (had results but not enough) : i915_enable_rc6=1 i915_enable_fbc=1 i915_lvds_downclock=1 pcie_aspm=force updated intel drivers (glasen ppa) Using chrome instead of firefox (had impact but not enough)

  • Proper 16:9 video size for non-HD 4:3 video (for youtube/vimeo)

    - by Xeoncross
    Since High Definition video came out on all the online sites it has changed the default aspect ratio of the player from 4:3 to 16:9. This means that for people posting SD video you have to resize some of your videos to get them to fit right. For example, NTSC DVD quality (aka 480i/p) is 720x480 pixels (width x height). However, low-end High Definition (720i/p) is 1280x720. Resolution Chart Anyway, now that the video players are built for HD you will find that uploading standard quality videos will result in videos that are "letter boxed" which means they have extra black bars on the top and bottom (or sides). Correct me if I'm wrong, but in order to get a 720x480 video to fit a box that is designed for HD the best practice would be to crop some of it off so that it fits as 720x404 since: 16/9 = 1.78 (1.7777777777778) 720/405 = 1.78 405x1.78 = 720.9 The same would stand for 640x480 (old TV quality) video that would need to be 640x360 correct? I'm asking because I'm not sure about all this and whether this is the proper way to fix these letter-boxing/display problems.

  • Best software to convert video to a different aspect ratio for various screensizes

    - by facepalmd
    I sometimes get .mp4 and other video formats whose aspect ratio is clearly off What apps do you use to reconvert such videos to an aspect ratio better suited to to fit either a regular desktop or LCD screen size? Hopefully with little or no loss of audio/video quality Any instructions on best settings to use would be very welcome. I have so far mostly used vlc which came off with less-than-ideal results. Thanks for any help you can offer.

  • Trancoding a video with vlc and the MPEG-4 codec with a video bit rate

    - by Nicolas
    When I try to trancode a video with vlc using the MPEG-4 codec and a video bit rate, I get the following error : Either both buffer size and max rate or neither must be specified Here is the command line I used : vlc -vvv myvideo.m2ts --sout-ffmpeg-strict=-2 --sout '#transcode{vcodec=mp4v,vb=2000,acodec=mp4a,ab=96}:standard{access=file,mux=mp4,dst=/path/file.mp4}' It seems that I can't specify a video bit rate with the MPEG-4 codec. (If I remove the vb option, it works). So how can I specify a video bit rate with the MPEG-4 codec ?

  • How to convert a video to 4:3 or 16:9 aspect ratio without loss of video quality

    - by Linux Jedi
    I uploaded my video to youtube and the highest resolution it appears as is 360p. This is much lower than what I uploaded. I believe that youtube isn't making higher resolutions available for my video because of its aspect ratio. The video is 720x400. How can I convert this to a different aspect ratio without losing any of the picture or picture quality? I don't care if blank space appears around the video so long as the picture doesn't get stretched horizontally or vertically.

  • How can I automatically lower Spotify playback volume when my Video Editing program makes a sound?

    - by Mark Major
    I'd like to listen to Spotify while I am video editing. This is just casual listening - nothing to do with the editing work. How can I automatically fade out the volume of Spotify when my video editing program plays audio? I often need to hear the video editing audio without the distraction of Spotify playing over the top, but the video editing playback is too on/off/on/off to switch Spotify audio manually each time. Without background music, I get really sick of the repeated playback of the audio clips with only silence inbetween. I suppose what I needd is an app that monitors sound output from 'App A' and reduces the sound output from all others (Apps B, C, D, etc) when something is played.

  • custom video icon for a single video file in windows 7 file explorer

    - by MrBrody
    recently I found a video on the net ( a .mp4 file), and when I had it on my computer with Windows7, I noticed its thumbnail was not the average windows 7 video thumbnail (which looks like a piece of video film with a random picture from the movie), but a custom thumbnail! Looking in the file properties did not help find the correct button to change the thumbnail...so I just wonder how he did it! Here is a picture: left: the custom thumbnail, right: the average thumbnail...

  • Flipping the video stream in Sony Vegas Studio!

    - by NoCanDo
    How do I flip a video stream, making it effectively appear to run backwards? For example, I've got a 6 second video stream. I cut it at 2, 4, 6, so I've got now 3 seperate streams with 2 seconds each. 1-2 ; 3-4; 5-6 - That's how it'll be displayed normally. Now what I want to do in Sony Vegas is to copy/paste and flip a selected stream. Let say: 1-2; 3-4; 3'-4'; 5-6 - The second 3-4 is copy/pasted; now I've got a video stream with 8 seconds. Now I want to flip this copy pasted making it effectively run backwards. 1-2; 3-4; 4'-3'; 5-6. The idea is I want something like a movie, it goes, and goes and goes, then a text appears "WAIT! What just happend?", then the movie goes back to second 3. 1-2-3-4-'WAIT! What just happened?'-4-3-4-5-6. I hope you get what I want to do in Sony Vegas.

    Is there a table that shows what is necessary for streaming video on demand? Specifically what I'm trying to do is stream Video on Demand to 50-100 people. I'm flexible with the format, but I'd like text on the screen to be legible (i.e. not 320x240). If someone knows of a calculator or something that would let me figure out exactly how I need to structure my video and ISP that'd be handy too.

  • Video/Animated GIF advanced frame editor?

    - by meder
    What sort of application could I use for example if I had a 5 minute video or an animated GIF with 50 frames, and I wanted to basically Photoshop replace an object, say a person's head, with another image for all those 50 frames? Is there some sort of smart tool that can do this or do I have to edit every single frame by hand? I wouldn't mind there being a tool where I can paste the image in every frame automatically, and switch from frame to frame adjusting the position of it, I just need something efficient. I've tried using Photoshop's import video into image sequence and tried editing with the animation toolbar at the bottom, but it's not quite what I want. I don't care if it's free software or not, I'm primarily using Linux but I have VirtualBox Windows XP if there's an excellent application that's not available otherwise.
