because your comp starts ar 00:00:00:00
yeah, that makes a lot of sense. Thanks
I see by your display that you are using Drop Frame timecode. Drop Frame timecode uses ; to separate Hr;min;sec;frames. NDF timecode uses :.
Don't panic, you're not going to loose any frames, DF timecode just doesn't count every frame so that the time works out to be accurate. In the time display you'll see 0;00;00;00 when your comp is set to drop frame. This is preferable when working with projects that must be a certain length like TV shows or commercials.
You'll see some missing frame numbers using drop frame timecode when, for example you go from frame 2;59;29 to 3;00;02. Again, no frames are dropped, just frame numbers so that the clock is right.
Non Drop frame time code counts all the frames so you would go from 2:59:29 to 3:00:00 but the clock would tell you that you clip was actually only 2;59;25 frames or you are about 1/6 of a second off. NDF timecode was developed so that hour long programs wouldnt be several seconds short....
You can change fron NDF to DF in the Comp Settings in CS6 or in the Project Settings in earlier versions.
The same thing still holds true for setting a clip to 500 frames or 5:00, you're going to be one frame short at the end of the clip because the CTI is going to stop on the last frame and the video will last until that last frame is played.
BTW, you can change that if you want in the Comp Settings (or project settings).
