Trouble exporting video with VideoExport library - no errors but no .mp4 written to file

Always good to look inside the given examples coming with a library.

ie:

hamoid/video_export_processing/blob/master/examples/basic/basic.pde

import com.hamoid.*;

VideoExport videoExport;

// Press 'q' to finish saving the movie and exit.

// In some systems, if you close your sketch by pressing ESC, 
// by closing the window, or by pressing STOP, the resulting 
// movie might be corrupted. If that happens to you, use
// videoExport.endMovie() like you see in this example.

// In other systems pressing ESC produces correct movies
// and .endMovie() is not necessary.

void setup() {
  size(600, 600);

  videoExport = new VideoExport(this);
  videoExport.startMovie();
}

This file has been truncated. show original

You’ll notice, that there is a call to …

videoExport.startMovie();

… right after creating the VideoExport instance, which seems to be missed in your code above…

PS: there is also a library called GifAnimation which you can check out…
