mpeg-2 flicker/shake only on standard def tv but not hd tv.
Hi,
I am trying to wrap my head around something. I currently am rendering a project out of encore with no compression. I am then using ProCoder to convert it to an mpeg-2 file. I then us this in encore to authour a dvd. All works fine except for one issue. When I play the DVD back on a HDTV there are no issues but when I play it back on a standard def tv There is a flickering/shacking that goes on the edges of the video (Where the video is being letter boxed). I have no clue what might be the cause of this and was wondering if anyone might have an idea?

That’s probably to do with interlacing. It happens on a lot of commercially available Hollywood DVD’s too, btw.
I’m assuming you meant you rendred a video out of After Effects and then used ProCoder. What sort of file are you rendering out of After Effects? What size, pixel aspect ratio, frame rate? Also, what kind of settings do you have for interlacing?

I am rendering out as a lossless Quicktime animation, 720 x 480 (3:2), and 29.97 fps. Excuse my green thum but where am I suppose to be looking for the interlace settings and what would I be looking to do once I have found such settings. 🙂

I KNOW, Star Trek’s credits were terrible! A lot of Hollywood DVDs are coming out with poorly done stuff. It’s like they’re so wrapped up in the new technology that they forget that the majority of their audience are still watching their stuff in SD.
Also, is it just me? It seems more and more commercials that are being broadcast are being done by idiots with no concept of field order. We’re talking national spots here! Graphics move across the screen all kinds of jumpy.
COME ON PEOPLE!

This page in the help file mentions it.
It’s called field rendering in AE. The field order matters greatly when it comes to SD. If it’s wrong, all the motion looks weird. DV is often lower field first. Most modern DVD players can play progressive files and it often looks more film-y that way. Try rendering it progressive (no fields) and with fields (both upper first and lower first) and see which you like best.– The Great Szalam
