I'm not well-versed with Unix shell scripting, and also only have basic proficiency in Windows scripting, so I can only offer a pseudocode flow of the script: 1) Break up your full video into N-second segments of only audio (into a temporary folder) ffmpeg -i GoProFull.mp4 -vn -c:a copy -segment_time n -f segment GP%03d.mp4 Obviously, this will generate a ...

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 --> 00:00:05,...

MoviePy looks less intimidating than other scripting languages. It may be easier to script your time tag cutting tool with it. http://zulko.github.io/moviepy/

Create your keyframes Select them by holding down Shift, via box select or simply click the Flare Brightness Property Then hold Alt and click the stopwatch icon, this will create an expression Then click the Expression Arrow > and select Property > loopoutduration this will cause that the keyframes to repeat themselves

You can do this with ffmpeg using either the concat filter or the concat demuxer. Which one to use depends whether or not your inputs have the same parameters or not. If they do not, you may have to perform additional filtering to make everything suitable to be concatenated properly. Example: concat filter For inputs that vary in frame rate, width, and ...

After Effects can be automated using the Adobe extendscript scripting language, and can be run from the command line, meaning that it can be integrated into other processes. Extendscript is JavaScript and it works across Adobe's product line (to varying degrees, you can use it to script Photoshop for instance). If you have a JavaScript developer available ...

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":

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.

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 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 ...

Have you got the latest version? After Effects CC 2018 is all about data driven animation. Either way you can use external file to drive expressions (in older versions too) using the eval javascript function. I explain it on my blog thus: If you have a file that contains something like this: var vals = {"rotation":8, "scaleX":150, "scaleY":200}; you can ...

Shift-Q does it - as per the following StackExchange answer which refers to images but this applies to videos too: Shift-Q - extend previous edit to playhead

Your idea sounds absolutely possible. On the other hand you write that you have never done any stop motion. I think it would be very well advised to start with some basic techniques (by hand) and then see what you can maybe automate in the future. Building puppets that can be easily animated is a already a complex task, since it usually involves building ...

While it doesn't cover all your criteria, I use a program called Total Commander for most of my file management needs and it works well for working with a very large number of files and huge file sizes. Among it's features, it is able to do a directory synchronization that determines the differences between to folders, either by filesize/date or by content (...

The answer is that this is not possible - at least as per the time of writing this answer, since the concept of "image sequence" does not exist in the XML spec Premiere utilizes - namely, XMEML version 4, also known as Final Cut Pro 7-style XML.

Automation Software might be a good option, although you'd need to give yourself a day or more to just get yourself up to speed learning curve wise. AutoIt is free, and you can basically code your scripts and then compile it into a program or batch file which you could run on a folder of files. I use a program called WinAutomation, which is similar to ...

I work with DataClay have built out several automated AE Comps allowing for thousands of personalized videos to be rendered based on data. I would highly recommend dataclay.com

I wrote an automation script for after effects that allows data and assets to populate a template I have worked with companies over the years extending this so that it runs on a server, takes assets and data through a web browser, and renders the modified template.


1

A script that generates a custom ffmpeg command based on inputs provided could do this. You'd need to construct a filter complex with scale/crop filters for each video and multiple overlay filters with time conditions for the compositing. If you're willing to learn and trial it out, grab the Win static binaries here and start with some basic guides.

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 ...

I had a similar need as yours - to produce shorter videos with different scenes from a single large video. I came across PySceneDetect which provides two kinds of cutting method: threshold scene detection (detect-threshold): analyzes video for changes in average frame intensity/brightness content-aware scene detection (detect-content): based on changes ...

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 :)

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 ...
