user19807: I have a source video file (@60 fps), and a "list" of frames of interest. I'm trying to get a "compilation" of 6 seconds clips (3 before, 3 after the said frame), add a fade in between them and output said video.
This is what I'm currently using:

melt test1.mp4 in=2340 out=2700 -mix 120 test1.mp4 in=4140 out=4500 -mix 120 test1.mp4 in=5220 out=5580 -blank 1500 -consumer sdl

The transition between the first and second clips is done correctly, the one between the 2'nd and 3'rd however is NOT processed.
Any ideas?

As a side note, I will have about 10-15 clips per movie, so I plan to move this to either a textfile or xml scheme later, but I'm trying to make this work from the command line for the time being.
Edit: 
Ok, so I figured it out. Turns out you need to apply the "-mix" flag to the SECOND clip, and it will mix between the previous and current clip. 

melt test1.mp4 in=2340 out=2700 test1.mp4 in=4140 out=4500 -mix 120 -mixer luma test1.mp4 in=5220 out=5580 -mix 120 -mixer luma -blank 1500

This now works correctly, and adds a fade between the first and second clip, as well as between the second and the third.
