Capture with scene detection

tserface wrote on 1/31/2002, 11:52 AM

Is the scene detection stuff supposed to figure out when the scene changes and break a capture stream up into different clips? It doesn't seem to work if I capture from a VHS tape through the Director's Cut box, and from my camera it seems to only use the time codes to break up the clips. Is there a setting I'm missing or is it really time code detection rather than scene detection?

Scene detection will only work on DV tapes that were shot with a DV camera. Shot, as opposed to recorded. If you are recording from VHS or whatever to DV and then capturing that, you'll get no auto clip detection.

Aha, so it is not really scene detection after all. Thanks for clearing it up. I was going nuts trying to figure out why it couldn't detect the differences in even the most blatant scene changes. Perhaps you guys should rename the option so it isn't so misleading???

Thanks,

Tom

Try ScenalyzerLive www.scenalyzer.com
It does both 'optical' and time code detection.

Recommended.

When using Scenalyzerlive what DV-AVI type should you select? (Type1 or Type2)
Does any one know the difference?

Tserface:
It is scene detection, but, probably, defined differently than what you imagined. My first video editing program was Pinnacle's VideoDirector 200 (a linear editor . . . very capable for it's day, by the way). Its scene detection was based upon scene contrast, and it would have detected scene changes in your VHS recording very well as long as those changes involved detectable levels of change in contrast.

To this day, I believe, Pinnacle's SD continues to rely upon contrast for its detection cues.

Vegas, as you've observed, uses the time code, and will detect those points where you've interrupted your recording sessions. For detection of tapes shot on your digital cam, this method is probably going to be more accurate. In the case of your VHS tape, it will treat all footage as one scene.

I am not a fan of scene detection, so I don't use it, and, therefore, cannot say whether Vegas allows you to insert a scene detection point manually or not (Pinnacle allows for manual scene detection . . . you view the preview window and press the space bar to indicate a scene change).

Well, it doen't work for me and my DV Camera when I shoot. I always get one clip only. If I use Pinnacle Studio Version 7, the scene detection works great. What is the problem with VV3? Is there anything in the preferences I could have missed?

Do you have enable DV Scene detection selected under perferences under capture?

I like that space bar idea... OK SF, add it to the wish list...

Yes, I have. On clip only. Always. I have also unchecked the box for "minimum length"

Clip detection in SF Vidcap also requires that the camera data/time be set prior to shooting. I've made that omission myself-
