No capture preview color

RWatts wrote on 7/21/2007, 8:44 PM
This happens with any dv tape - the device captures, but the color disappears on the preview and one sees a ghost in white, green and black of the scene. However, when the capture is complete, the preview thumbnails look normal, and the captured scenes are fine in VMS. The problem is, we like to capture selectively, and it is hard to judge from the washed-out image.
Any thoughts?

I assume you use Video Capture 6.0? If yes, I could not reproduce the bug here. Might just be a slight incompatibility between your camcorder and the capture program... The bug might be fixable in your camcorder;s settings actually rather than the capturing app.

Imho, this may be a driver issue.
Go to the graphics settings of XP, find 'hardware accelleration', and turn it off and see what happens.

If that brings back the colours, you may want to install the latest drivers for your graphics card.

No, I should have clarified that. This problem occurs on version 3B, which I have on a second computer for an assistant to do pre-editing. On my main computer with VMS 6, it works fine from the same camcorder.
The hardware acceleration was set to maximum, I will try it withy it turned off now.

Ivan;
That did it! Capture color returned with the accelerator off. According to Winows XP, we have the latest driver installed, so I'll see if we can just carry on in this mode.
Thanks

My bet is you have an Nvidia graphics chip on your pc. These chips give problems with Apple's Quicktime. My guess is that Vegas uses the Quicktime engine for the preview screen.

I"m not sure if this will work, but you should give it a try. Instead of turning down hardware accelleration in windows XP - which affects all of the pc - you can turn it down in Quicktime only. Run Quicktime Player, go to Quicktime Preffereces>Advanced and turn off DirectDraw Accelleration.

Good luck, and let this forum know if it worked!

Hmmm, i find it doubtful that Vegas uses QuickTime for the preview display. Vegas and VidCap's previews works fine even without quicktime installed.

Ivan and Chienworks:
I'll give that a try when the operator gets off the machine, but at least we are back in business temporarily.
Thanks
