Hi all,

I've just shot a short with this camera and am in the process of syncing the video to the externally recorded audio.

Lining up the WAV file with the transcoded video (both Cineform RAW and MOV out of DaVinci produces a video file that is a frame shorter than the audio file that is created.

Is that normal or is there a discrepancy in the transcode?

I have noticed that when I lay the video into Premiere, it tells me that, for example, the duration of a clip is 0:01:45:20 (one minute 45 seconds 20 frames) but the start time and end time are listed as 0:00:00:00 and 01:45:19. So a discrepancy of one frame.

I can't figure this out. I certainly don't want to start my edit only to discover that I am not editing with frame accuracy.

Thanks for your help,

Unless I'm misunderstanding something, there IS no error in the report. The 00:00:00;00 frame is a frame and contributes to the frame count.

00:00:00;00 to 00:01:45;19 would have a duration of 1m45s20f

That's what I thought - just semantics of numbering. A bit like digital addressing, 0 to 254, or 1 to 255 - same thing!

You can't really have a frame zero - the first frame has to be frame 1, doesn't it!

The frame 0 is ACTUALLY frame 1 but then the whole concept of "backspacing one" to get the elapsed time would come into play...

Ugly, I know...

I guess I understand, but why then am I getting longer duration video files than sound files?

If you were in NTSC land, I'd say it was a Drop Frame versus Non_Drop Frame issue but you are in PAL land...

UNLESS you recorded in 23.98 instead of 24...
