If I were to try simple cut edits with melt using the following command
melt InFile.avi in=80 out=120 -consumer avformat:OutFile.avi
How will melt implement this? Does it jump to frame 40 and only decode
the next 41 frames? Or does it decode the entire file and only output frames
40-81. My input file has no inter-frame compression, and each frame is
comrpessed with ffvhuff.
The reason I'm asking is I have a very large input file, 100000 frames,
and I would like to split it into smaller segments to so I can mpeg4-encode
them concurrently. If I have to step through the entire file each time (some
tools
do it this way) to edit segments, then that would be prohibitely slow.
Also, if I tell melt to start an edit at frame N, how does it compute N? Does
it select the N-th actual frame of video data that's actually stored in the
file?
That's what I want. Or does it first try to sync the video with audio, then
add or delete frames and then figure out what it thinks the user really
meant by N? I don't want that.
