Problem convering 23.976 avi to SVCD

[Spaceboy]

When I convert a 23.976 avi to svcd using the ntsc film template, although the film plays ok, I have a slight flickering effect on the screen, i.e. I'm, playing a widescreen film on a normal 4:3 television and throughout the film the borders at the top and bottom are continuosly moving up and down.

I have the video source type as non-interlace (progressive) and the encode mode as 3-2 pulldown when playback.

Is there anything else I need to alter?

Try changing the field order.

progressive sources dont have a field order -- they are progressive ..


which begs the question are you sure the source is progressive ?

what is the avi made from ? dvd or vid capture ...

did you try to just crop out the edges a few pixels ?

the borders at the top and bottom are continuosly moving up and down.

When you do your encode, in the advanced section double-click the *clip frame* option. Clip 2 pixels off top and bottom, and select *Top mask* and *Bottom mask*.

Tried to crop a few pixels off the edge. Didn't make any difference.

The avi is a DVD rip. How can I check whether the source is interlaced or not?

use bitrate viewer (great program - specially the full version) or dvd2avi or vitec dvd tools ..

Avi is not interlaced. If it was created from an interlaced source incorrectly there could be interlacing effects. If it was incorrectly cropped this may account for it, but it sounds exactly like what happens when I import DV from my camcorder without trimming off the top few pixels. Whatever it is, you will be able to remove it by using the *clip frame* setting in TMPG. Maybe you didn't enable the clip frame feature, or didn't clip off enough pixels? If this doesn't work then I suggest your player may be defective.

- not sure what you mean , there can be interlaced AVI's for sure , as well as of course interlaced DVD's

I presumed we were talking about DivX avis, which are not interlaced.

ahh yes of course .. as are vcd's -- i see what you mean ...

Well, I've just re-encoded it with non-interlace as the encode mode (rather than 3:2 pulldown when playback), and keeping the original framerate of 23.976.

The flickering has completely gone and playback seems pretty smooth.
