Useful for putting your own soundtrack under a clip.
Good to know
Two ways, both tested. 'Mix Audio' adds a music file to a video that already has sound. If the video has no sound, 'Mix Audio' does not work (an error appears and the old output stays): use 'Raw FFmpeg' with the example 'Replace audio track' instead, which gave a silent video sound. That last way is less user-friendly. Tested with a short mp4 (4 seconds, 320x240); large files were not tested. According to the developer, there is a memory limit of about 2 GB. In English; first loads an engine of about 31 MB.
