You could do this by making subtitles from your data streams and then either playing them back on a media player that can display subtitles, or rendering them into the video. Most subtitle formats are very simple ascii files — to demonstrate, here's an srt subtitle file: 1 00:00:01,046 --> 00:00:02,540 This is my home. 2 00:00:03,560 --> ...

The obligatory ffmpeg answer (not a very good one, other answers still needed): You could feed your video through ffmpeg -vf drawtext=textfile=onscreen.txt:reload=1 With whatever other drawtext options you need to put your text where you want it, with the font you want. reload=1 makes it check the text file for changes every frame, but doesn't give you a ...

You can also try to use Avidemux -- its free and open source program + you can use it on Windows, Linux and Mac. Here is the documentation wiki on Avidemux, where you can find section "Scripting":

I found out about melt and created video-splitter which is a command line wrapper around the former. There might even be a very elegant way to do everything in a command pipe with two or three commands or even everything with one melt command.

The only recent tool I know is a plugin for After Effects called Magnum - The Edit Detector. While After Effects isn't exactly the most suited program for these kind of tasks it would do what you want with some sort of control over it. You can export the resulting clips/layers in After Effects via a script like redefinery's Layer Render script (seems the ...

Take a look at Sony Vegas Pro. It supports scripting automation based on .NET (C#). There are third-party extensions like Vegasaur, which contains a lot of scripts and tools.

I'm sure Virtual Dub http://virtualdub.sourceforge.net/ can do what you want, though there may be simpler scripted cutters out there. Before investing too much time in the script, be sure VD can handle the particular codec(s) you'll be using.

Consider the following technologies: ffmpeg + command line Adobe After Effects + ExtendScript language (based on JavaScript) Sony Vegas Pro + C# language (or any other Microsoft .NET language)

To automate things like that you will have to write a script for After Effects. This isn't all that hard, it just requires a bit of programming knowledge. You can see them as more powerful type of expressions that can actually control the whole program not just your comp, so you can mage changes to your layer based on certain other aspects. For example you ...

I hope there is a better answer, but my similar case is making lower thirds where I have to change out the name. In that case, I have a static composition with the title that I use as a source in other compositions. I then create a text layer for each name, hide all but one, click through to the final render comp (using the parent/child links) and start a ...

There is no Action function in Adobe After Effects. You would have to write a script to do the sequence for you. I'm not versed enough to tell you if there's a Plugin or not.

I would honestly suggest outputting the whole thing to a lossless format and then using another tool to split the file. Depending on if you have audio, it could be particularly easy to do by exporting as an image sequence and simply moving and renaming the images for each 30 second clip and then encoding each. If they have audio, then you'd want to ...

Quite an expensive solution: Sony Vegas Pro + Transcoder plugin can do it :)

You can achieve all your goals using ffmpeg and sox, these are command line tools for video and audio processing respectively. I can not provide you with a ready to roll solution, but here are examples for a pre-roll video, audio noise reduction, text overlay and conversion from AVCHD.

I would use a particle system to do this, like Particular or Particle World. Particular is part of the Trapcode Suite of AE plugins, and is the easiest to use. http://www.redgiant.com/products/all/trapcode-particular/ Generate a load of particles in random positions Make a pre-comp with all the different text layers on different frames, so one text object ...

I haven't done this myself, but I think it's quite doable. First, you'd need to setup a ffmpeg script to demux the video into audio and video portions. Then, you'd need to apply a script that will analyze the audio file. Silence is easier to automatically detect in an audio file, assuming that you can produce the silence on site to mark the intervals (e.g. ...

try Freemake (older version, latest adds a watermark) or video to video converter.Both have easy to use graphical interface.
