Rendering 640x480 25fps Indeo avi files -> MPEG2 for DVD

prairiedogpics wrote on 7/19/2004, 6:13 AM

I have some avi files from my pre-Vegas days that I want to put on DVD. Most of them are 640x480 avi files, at 25 fps and rendered with an Indeo codec or MJPEG hardware codec. I was able to render them all to the default settings for MPEG2 for DVD, but when I view them on the DVD player there is pretty severe flickering (due to the difference in frame rate?)
How do I get rid of or minimize the flickering?

Would you suggest I match the framerate in the MPEG2 render to the original frame rate of the avi files (25fps)? Would "reduce interlace flicker" help at all?

are you rendering to NTSC or PAL ?

if rendering to NTSC , you would slow the clip down to 23.976 and add pulldown (from a progressive source) , if rendering to PAL , you are at PAL fps now but you didnt say if your source is progressive or interlaced for field order ..

Indeo codec clips will ussually look bad , you may want to letterbox them and leave borders (they would have to be letterboxed slightly anyway as they are 1:1 pixel ratio and NTSC or PAL is not) ..

Thanks for the reply, B_JM

I'm rendering to NTSC.
A couple questions: How to I slow the clip down to 23.976 in Vegas? You're not talking about about a velocity envelope are you? This is the setting in the properties dialog, right?

How do I "add pulldown" in Vegas. Sorry to be so dim...

I'm not sure if I did this right, but I made the project properties NTSC DV 24p, and then I rendered to MPEG2 DVDA NTSC Video stream with the framerate set to "23.976 + 2-3 pulldown".
This reduces the flicker (overall strobing effect of the entire video, I guess you would say), but caused major combing during wipe transitions in the original avi file. Any way to get rid of the combing AND flicker?

the original avi is 640x480 25 fps progressive Intel Indeo(R).

I'm just trying to get the best quality converting it to MPEG2 NTSC DVD.

Thanks for any help.
