    Hello

    I like ffmpeg because it compresses video pretty well, and would like to use it to cut a video by using frame numbers instead of time.

    By opening a FLV file (h264 + aac) in VirtualDub, I could write down the start and end frame numbers, but it looks like ffmpeg only supports time through the -ss and -t switches. Can someone confirm?

    Alternatively, do you know of a Windows application that 1) can open MP4 or FLV files, 2) cut a file precisely to the frame number, and 3) re-encode the cut sequence as efficiently as ffmpeg?

    Thank you.

    Edit with virtual dub and export with ffmpeg via external encoder.
    Got my retirement plans all set. Looks like I only have to work another 5 years after I die........

    Is there a tutorial that explains how to use VirtualDub and ffmpeg?

    How can VirtualDub use ffmpeg to cut on frame numbers while ffmpeg doesn't seem to support it?
