3 AUDIO VIDEO COMBINE

For personal use. Connects videos with audio. Still in testing.
Note that it does not work with videos without audio.
If you must use videos without audio, the audio file set at the beginning of "AUDIO+" is silent. Please use that to create a video with audio first.
Initial fps 30. Can be changed.
Volume of each video can be adjusted. Variable 0-1, where 1 is 100% volume.

If not all load slots are filled, blank spots will be filled with the first file instead.
