You can convert audio to keyframes. Right-click the footage with the audio, and choose Animation>Keyframe Assistant>Convert Audio to Keyframes, or with the audio layer selected go to the Animation menu in the menu bar. This will create a new layer with keyframes for the intensity of the audio. You can copy those keyframes on to any property that you want ...

I second the vote for Processing, but if C++ is more your thing than Java you could also look at openFrameworks. It allows for more processor-intensive computation and as such is good at real-time synthesis and manipulation of video. Another tool worth checking out is NodeBox. It allows for coding, but wraps it all in a node-based GUI, the aim being to ...

You should check out Processing dot org.

From what I understand 't' is evaluated once. Have you read this: https://ffmpeg.org/ffmpeg-filters.html#zoompan ? Ffmpeg Docs: 9.170.1 Examples Zoom-in up to 1.5 and pan at same time to some spot near center of picture: zoompan=z='min(zoom+0.0015,1.5)':d=700:x='if(gte(zoom,1.5),x,x+1/a)':y='if(gte(zoom,1.5),y,y+1)':s=640x360 Zoom-in up to 1.5 and pan ...

I do not know of any existing solutions for this in Premiere or AE. However, if you know a little about programming, you might be able to write a script using OpenCV that runs Tesseract OCR on video frames, and comes out with the text you want. Once you have the text and time codes, you definitely could write a script to build the titles at the appropriate ...

To add upon John's answer, one way to do this using FFmpeg would be to add your filters (in C), but another, more modular, way is to code a Frei0r plugin, which can then be used with various host applications, whether FFmpeg, MLT..etc Frei0r is a minimalistic plugin API for video effects. The main emphasis is on simplicity for an API that will round up ...

As an alternative to Processing, if you prefer to use C#, you can write plugins for VVVV using their C# APIs. Also if you prefer to just write pixel and vertex shaders which you can apply to your audio/video, they support that as well.

Trapcode Particular is the tool of choice for this. You can generate any type of noise/particles, based on an audio track, and tie the parameters to not just the track, but specific frequencies (so the noise is warped on low bass, or changes color on high frequencies). There are also a lot of templates you can buy on videohive that will jumpstart the ...

My thoughts as a programmer: You can make make watermark hardcoded in the video, and remove it with the script in your player. For example you add big text "STOLEN" in your video but not with white or semitransperent font color, but with inverted color of every pixel. Like that: After that, player on your site will invert those pixels again on the fly. You ...

I believe You want to delete some objects from Your scene. Adobe After Effects recently introduced a feature allowing users to do just that: Documentation: https://helpx.adobe.com/pl/after-effects/using/content-aware-fill.html Video example: If You meant anything else please clarify Your question a little bit more.

Most professional quality video editing software has this kind of functionality. You can take a look at DaVinci Resolve, which is available for free on Linux. This article has more details about how to do it, but "Scene Cut Detection" is the name of the feature you are looking for and it's available when right clicking on a video file.

To my knowledge there is no tool available for editing After Effects project files other than After Effects itself. However you can script After Effect using Adobe's Extendscript language, so that it will work without user interaction, and even without showing the GUI. Extendscript is based on ECMAscript (basically it's Javascript) and allows you to do ...

You can code custom plugins for Shotcut video editor using MLT, frei0r, or WebVfx plugin. MLT and frei0r plugins require C or C++ coding; whereas WebVfx lets you use HTML5, CSS3, JavaScript, SVG, and WebGL. : https://shotcut.org/notes/make-plugins/ I like unity3d for audio/video things Obviously, have a go on Milkdrop if you want fluid dynamics code, else ...

You might want to look into using FFmpeg - it seems like the kind of tool you're looking for. Adobe's After Effects allows some custom scripting, but not nearly to the extent you're looking for.

There isn't really an alternative to x264vfw. Are you sure the error is with the codec and not your application? It's in wide use, such a major bug would definitely be found. Also be aware that h264 doesn't work in a frame by frame basis unless you encode only intra frames. VP80 is NOT h264, just a similar codec. If you need to develop an app you probably ...

No there isn't - DVD authoring does not include 'expiry' option.
