I have a video project I am trying to compile. Here is the overview:
- I have many videos which are 5 minute training sessions - Main video.
- The Intro Video will be a standard 5 second video that will have the Video title and Author. This will be concatenated to the main video.
- The Trailing Video will pretty much be a stock video that will be concatenated to the main video and have all the legaleze etc.
- The Intro Vid will smoothly fade into the main vid as well as when you get to end of the main video it will fade into the Trailing video nicely.
- The product is a new video with a Intro, Main & Trailer video all in one!
The concept is really that simple. In fact I found an example of a person who has solved this and is doing exactly what I want.
This solution is a Bash script that takes a config file that has the title, author, etc. and generates the Intro, the Ending and creates the resulting video with them concatenated.
I am using Ubuntu 12.04 Server. I have been trying to take this as a sample and just running it with no luck because of incompatibility errors. I even attempted to convert it using .MP4
containers or .MKV
. I am running into error after error or incompatibility issues. I went as far as changing out the ffmpeg
binary using the 25 Oct 2013 version from http://ffmpeg.gusari.org/static/64bit/ which I like as I don't have to worry about rebuilding the binary. Almost successful but again I have some error which I cannot solve.
I know part of the problem is the fact that video production, codecs, formats is a completely new field for me so I am attempting to work through this new territory.
Perhaps an expert here has something similar that I can use as a guideline that uses MP4 or h.264 format. Or take the solution above from the URL and make it work with a more up-to-date version of ffmpeg.
I will include the script and its parameter file and the output (abbreviated because of limitation) below. Basically as the script stands right now, when run I get the error [matroska,webm @ 0x27bbee0] Read error
.
This error is return from the 'reasembleVideo' routine from the first ffmpeg command.
The following is the Parameter File:
#!/bin/bash
INPUTFILE="ssh_main.mp4"
LOGO="logo.png"
LOGOLENGTH="1"
SPEAKER="Jason"
TITLE="Basic SSH Video"
DATE="October 28, 2013"
SCENESTART="00:00:01"
SCENEDURATION="00:00:09"
OUTPUTFILE="ssh_basic_1"
}
The following is the script I am running. The ${OUTPUTFILE}
being used is a small 2 minute video I create in screen-o-matic in MP4 format.
