Help...scene detection issue

PH125 wrote on 7/27/2004, 11:51 AM
I used to be able to capture video with perfect scene detection in Vegas 4, but with Vegas 5 there is a problem. I turned on the scene detection option, and it captured the video without a problem. However, it only split it into 4 clips, while it should really be split into at least 30 due to clear and defined scene shifts in the video due to the starting and stoping of the cam. What am I doing wrong?

Is the clock in the camera set?

How big are the 4 pieces? If they're about 4Gig each, I'd say those splits are due to a FAT32 formatted drive (NTFS would give one large file instead of 4 smaller ones)

Also check your minimum clip length setting.

Checked all of that, everything is fine. I have an NTFS drive. But the problem still remains...

Does the timecode change on the tape at these cuts (where you would expect it to cut)? Or is it one continuous trimecode throughout the tape?

I just checked the tape, and the time code does change at the points at which vegas split the footage. When one clip finishes, the timecode goes back to 0. However, there are a number of different clips within each clip that should have been split.

As far as I know Vegas will only make a split when the timecode jumps on the tape. I might be wrong on that though because I don't normally use scene detection.

I believe it's looking for jumps in the time-of-day, not the timecode. This works fine for me. A break in the timecode is likely to cause problems, particularly if it resets to zero, because there's no way for the capture utility to know "which half" the clip is that you want. It can be easily remedied if you have another camera by simply copying the tape - of course - then you lose the TOD jumps and scene detection won't work then either but at least you'll have a repeatable batch capture list if you go that route.

Vegas splits based on jumps in the date/time code. Are you SURE the clock is set in the camera?

"Vegas splits based on jumps in the date/time code"

This is what I thought and it makes complete sense, he said that at the place Vegas was splitting the file the timecode jumped. The timecoed doesn't jump where he thinks there should be a break in the file. So since the timecode doesn't break, Vegas just assumes that it is all one clip.

Vegas makes a slpit when the "time of day" code jumps. Not the timecode.

No. Not at jumps in SMPTE timecode. It cuts at jumps in the time of day, which is also recorded onto the tape.

Be that as it may, it's curious that the timecode on the captured clips is starting at zero for each clip. That ain't right.

It's not my tape, it's someone I working for's footage.

Is there any way i can split the files in vegas without having to re-render them?

I'm sure the timecode is resetting to zero because at those points in time the recording was NOT started inside the previous timecode so it reset to zero.

Since it is not your camera, I'll also bet that the clock was not set causing the tape to NOT be split.

I guess you could try the optical detection in Scenalyzer. OR you can manually pick the sections and make subclips.
