ITT: ways of extracting clips from videos and editing them.

Here's a screen capture showing how to use ffmpeg and Avidemux to cut and crop a clip from a video. I've sped the action up by a factor of 2 so it's easier to watch.

I start by using converting the video into a format I know Avidemux can read. This isn't always necessary (and, in fact, wasn't in this case), but I wanted to show it anyway. To avoid having to convert the whole video, I start by opening it and finding the approximate time of the clip I want.

Then I invoke ffmpeg at the command prompt to convert the video:

ffmpeg -ss 20:40 -i source.mp4 -t 20 -pix_fmt yuv420p -c:v ffvhuff -an tmp1.mkv

To break this down:
> -ss 20:40
start at 20 minutes, 40 seconds
> -i source.mp4
input file is source.mp4
