Scene Detection

Hi,

I'm using Vegas to capture digital video from my Panasonic DV cassette deck. In the video capture preferences, I have "enable DV scene detection" checked, but when I actually capture the video it seems to chop the video into random scenes, without regard to pauses or stops in the video itself. Usually it gets split into far fewer scenes than there actually are in the video.

How can I change it so that it cuts up the video into scenes at every pause or stop point?

Vegas scene detection only works from breaks in the timecode recorded by you camera during "filming." I.e., if you record continuous timecode, you get no scene detection. You can check out the topic in the manual for more info. I either go to advanced capture and individually identify the clips I want captured, or capture a continuous stream and break it up in the trimmer. DGrob

To clarify what DGrob stated:

Scene detection works by reading the time (as in time of day) information which is encoded on your DV tape as you shoot, not timecode (the frame address), which SHOULD be continuous on your tape.

Vegas' scene detection is based on time of day code on the tape. If there were starts and stops while recording then that's where scene detection will make a break.

Of course, you must set the clock on your recorder.

Scenalyzer has optical scene detection. That may be what you want. Otherwise you might have to log the in-out points yourself. Happily, after you've done it and captured once you can then re-capture the clips again a year later.

Any time you start or stop your DV camcorder, it will cause a break in the timecode. However, if you rewind the tape and then start taping, you can sometimes get very small remnants (just a few frames) of the previous segment. These short segments can cause the capture to malfunction.
