Your PLAYER will control the video speed..
..
but if you mean in the EDITING of a Digital Video Project../??
..
there are [fps]..
..
the best in Digital Video is 30-fps..
..
in the RENDERING of DV-->>mpeg2..there are some numbers calling out even 1700fps..<<--I'm confused on that one..
..
Video Speed is correctly called Video Playback-->>Speed..
..
This is a SETTING in the PLAYER...Configurations..or TOOLS-->>Options..
......................................................................
Also if your confused than you may have even ruined your DV..
and really nothing means anything except...start over.
