rendering rendering...

I'm trying to render something at 15fps, originally shot at 29,97fps. The problem I got is that I get these horizontal cutting lines across the image. Is it because I'm trying to compress to 15fps? these lines are not thick grey lines, these are invisible lines that seem to "cut" between two different frames so what's up in the image is not "synch" with what's down. They can happen like three times on a 4 min video, each time "striking" between 2 to 5 times...
Is that too abstract? :|

I tried rendering out to 15 fps, but had no problem. What format is your source file? Output file? Any audio? etc. Then people (like me) can try to replicate the problem to see what's causing it.

My source file is:
(and I'm telling you all that's on the info tab)
file extension: MOV
Format: 16-bit little Endian, Stereo, 32kHz, 16 bits
None, 266x200, Millions+
FPS: 29,97
Data rate: 6,2MB/sec

I'd like to render for Web in MOV for streaming.

Thanks for the reply by the way!

Are the lines there in the original file - just one of 30 instead of 15?
KNow it's an extra step - but would it help to save the mov file at the new rate (or as an avi for editing) first using the q/time player/encoder?

Almost sounds like you had interlaced source material that didn't get deinterlaced because the field order property wasn't set right, or the deinterlace method was turned off.

I also have troubles with slow motions. My vegas doesn't make lines, but it pixelates. Every time i try to make a slo-mo, whether is by expanding (ctrl+clicking) the event, or by adjusting the velocity envelope, the result's the same when I render or prerender. I can even see the pixels while previewing the rendering action.

Another strange thing is that when i preview it normally, I mean, with out rendering, it looks just perfect.

Somebody help me please!

SonicDennis: so... is there a cure somehow? Rendering with interlaced/progressive? I don't know...?
