Rendering Troubles

gallois wrote on 6/21/2004, 2:06 AM

I've been having this problem for a while now:

When I render a timeline I'm getting random corrupted clips. When I check the media settings for that clip in the timeline, the field order has changed from "lower field first" to "None (progressive scan)". Somehow the program is changing the settings of random edits and the resulting video looks jittery and weird, definitely not broadcast quality which is what I need. I also notice that on the properties menu for video event, the setting has gone from "maintain aspect ratio" to "reduce interlace flicker". Has anyone else noticed media settings seemingly changing by themselves?

Thanks for any help with this problem.

Where did you capture the media?
What are your project properties?
What kind of media is it? (PAL/NTSC)
Rendering to which preset?

"Where did you capture the media?"

All the media is NTSC DV transfered from Canon GL2 cameras via firewire using Vegas capture mode.

"What are your project properties?"

NTSC DV, Lower field first, 29.97 fps, resolution: good, motion type: gaussian, deinterlace: interpolate. Also the "maintain aspect ratio" and "smart resample" boxes are checked.

"Rendering to which preset?"

Render to .avi through Broadcast Colors plugin. (Template: NTSC DV)

I've had this same problem on two different machines. Sometimes I'll let it render in the background while I edit something else in a new timeline.

Thanks.

Is it OK to render a clip in the background while I edit another piece?

Nobody else seems to to be having this problem based on numerous forum searches over the past few months, so I have to assume that it may be a hardware related problem, except that it's happened on two seperate systems. Could corrupted source video be the cause of this?
