extracting clips

What's the best way to extract/make clips from a video file?

Better, is there any way to make virtual dub not to save along with the clip I want the first keyframe in front of it?

ex:
frame -
keyframe +

video: -----+---------------+-----------
I select to save: --
the program saves: +--

pls help!

Well, if your source video files weren't encoded with delta (or P- and B-) frames, you wouldn't have this problem.

I suppose you could try serving the files with AVISynth, which forces VirtualDub(/Mod) to see every frame as a keyframe.

thanks man. and how do I do this?

If your version of VirtualDub has an "Open file via AVISynth..." option on the File menu, use that to open the file. It will automatically create an AVISynth script for you in the same directory.

If not, pull up the usual Open dialog box and see if there is a drop-down box marked "Use AVISynth template".

If neither of these is the case, then get <a href="http://virtualdubmod.sourceforge.net">VirtualDubMod</a> instead and try again.

.. doesn't it strike you as "a little bit" strange .. that the first frame was somehow saved without being a Key Frame ? ? ?? ?

Um, how do you get that from "the program saves: +--"?

by what they are trying to save:

Clearly the OP didn't actually mean s/he was taking frames from the very beginning of the video. The first frame can't be a delta frame, because if it was, it would have nothing before it to refer to.

By way of clarification: HDjunkie, you meant to say that the program saves starting with the first keyframe before the first frame of your selection, right?

.. Scintilla although you and I may know the difference, they may not understand what the editor is trying to correct ...

.. if I understood the question correctly; they wanted to know why they were trying to save non-key frames and the Editor kept saving only the locations where a Key Frame was available.

-- I could be wrong

not starting, just the keyframe and the selection, nothing in between.
