Vegas Rendering Issue - Help! (Please?)

Hi,

I've imported some footage from a film I'm working on into Sony Vegas 7. The footage was shot on a DVX100b in 24p widescreen squeeze mode with a RedRock M2 lens adapter. The footage, when played back on the camera's viewfinder or on a television, is fine. When rendered out of Vegas and viewed on the computer digital lines appear onscreen, usually when there's a lot of movement. I've ruled out any issues with the tape/footage itself. The problem comes after rendering out of Vegas. Can someone please recommend the settings to render out of Vegas or advise if they've had similar problems? The specs I'm rendering out to are below:

.avi
NTSC DV Widescreen 24p (2-3-3-2 pulldown)
Audio: 48,000 Hz, 16 Bit, Stereo, PCM Uncompressed.
Video: 23.976 fps inserting 2-3-3-2 pulldown, 720x480, Progressive.
Pixel Aspect Ratio: 1.212. OpenDML compatible.
Widescreen NTSC DV video files compatible with Sony Video Capture.

Project settings are:
NTSC DV 24p Widescreen (720x480, 23.976 fps)
720x480
Field order: None (progressive scan)
Pixel Aspect Ratio: 1.2121 (NTSC DV Widescreen)
Frame Rate: 23.976 (IVTC Film)
Motion Blur Type: Gaussian
Deinterlace Method: None


Is this something to do with the field order or the deinterlace method? If someone can please let me know what the ideal project and rendering settings should be for a project of this type, I would greatly appreciate it.

Thank you!

*Edit* One other possible factor - using the RedRock lens adapter we don't have the image flipper so I'm flipping the footage in Vegas. I've heard that this could possibly mess with the field order, etc.
 
No, it has nothing to do with the deinterlace method. Don't let anyone tell you need a deinterlace filter or to deinterlace the footage. You do not want to do that.

It's because you rendered to NTSC DV. The lines are interlace lines; it's normal, because NTSC is an interlaced format. When you export to NTSC DV, you have to add interlace fields, which is what pulldown is. It's that way on tape, too, but you don't see it on a TV screen because it's interlaced, too.

What do you want to export FOR? Exporting to DV is pretty much only for going back to tape, or for broadcast, or for delivering to someone else for editing.

If you want to watch it on your computer, you should export to a non-interlaced format, preferably at 23.976.
 
Thanks for the info. I double-checked and the lines didn't appear on the video when watched on a television. As for what I was exporting it for, I was in the process of flipping the image and syncing audio and wanted to export it to get review the footage to make sure everything looked ok. Thanks again!
 
OK. Glad it worked out.

You should mention if you're manipulating the footage when you ask these things, though.
