Yes, I have had this happen to me.

Try unchecking the minimum clip length or setting it to 0 in the Capture Preferences.

Does your video happen to be a time-lapse?

Are you guys capturing PAL or NTSC?

Deef, I'm using NTSC.

You were the one that got my problem fixed. My above post was your suggestion and it worked for me.

The video that I was capturing was a time-lapse. My camcorder recorded for 0.5 seconds every 30 seconds, I forget what the default minimum clip lenth is, but it is not zero.

As Chienworks posted in the VF forum, you should also uncheck (or disable) the 'enable' DV scene detection for 'time-lapse' video, other wise you will may get 800 + different clips as I did.

Diako...any comments or did you get it working?

Ahhh...right. What DV device are you using Stiffler that allows time-lapse?

You shouldn't have to disable or set min clip length to 0, if you disable DV Scene Detection, in the case of time lapse capture. Your problem was because DV scene detection was capturing many clips because of the date/time stamp discontinuities due to time-lapse, but the min clip length would cull them because they were less than your time lapse interval. Disabling DV scene detection should be all you have to do for this to work.

Can you please verify this is the case?

Thanks!

I have a Sony DCR-240 Digital-8, (not DV...it records to tape).

Disabling DV scene detection eliminated my 800-plus clips, yes.

In the case of using time-lapse with this camera and Vegas, you do need to set the min. clip length to zero. Recording my time-lapse...I had it set to record for 0.5 seconds every 30 seconds.

Does this make sense?

This was not a Vegas problem, just a default parameter...the default min. clip length in Vegas and VF is above zero (I forgot what it is-like 5 seconds).

My suggestion is to make the default 'minimum clip length' at zero.

Thanks for asking.
