I've done a bit of work with FFMPEG in my days and I am somewhat familiar with VirtualDub as well as high-end products such as Sony Vegas.

However, I still can't figure out a simple and straight-forward way to extract frames M to N out of a given WMV file and encode that into an x264-encoded video.

I use Windows 7 64-bit.

Any ideas?

You first have to figure out the start time of the first frame in HH:MM:SS.msec format, or in S.msec. Then, where <start> is the timecode:

ffmpeg -i input.wmv -ss <start> -c:v libx264 -frames:v 123 output.mp4

If you want to use filters you could do something like this, where 100 is the frame to start from:

ffmpeg -i input.wmv -filter:v "select=gte(n\,100)" -c:v libx264 -frames:v 123 -vsync 0 output.mp4
