Video editing >

This is an aborted project from when I was thinking of manually implementing a dissolve feature.

• Fade (audio engineering)

• Dissolve (filmmaking)

kino can do this!

• A fade-to-black idea.

  • Requires a patch to FFmpeg.

My idea ∞

1. Take 10 frames from source a as PNG images. (FFmpeg?, MPlayer?)
2. Take 10 frames from source b as PNG images.
3. Apply transparency effects to those 20 images, from 0% transparency to 100% transparency in source a, and 100% to 0% in source b.
4. Merge the 10 source a and 10 source b images together. (1-10 a with 10-1 b)
5. Create a video out of those 10 images.
6. Cut 10 frames from the end of video source a.
7. Cut 10 frames from the beginning of video source b.
8. Calculate how many frames equals how many seconds.
9. Clip the audio from the two sources.
10. Use SoX to cross-fade the two sound sources.
11. Apply the cross-faded sound to the transparency-picture video.

12. Merge the new source a, the transparency-picture-video, and the new source b.

Problems:

• cross-fade the sound too.
