Flicker problems after encoding to Mpeg2 in Premiere 6.5

[jones_randy]

I am using Adobe premiere 6.5 and I have created a video footage and photo montage video. It looks great when playing back in Premiere and after copying to a VHS tape. The problem is, after I encode it to a MPEG2 file, to get ready to burn to DVD, some of the pictures but not all of them have flickering/dithering in them and it is very noticable. The video looks fine, but just certain pictures do this. I can play the mpeg before burning it to dvd and I see the problem, so I know it is in the mpeg file itself, because it also plays fine in adobe, before I encoded the mpeg file. (I also went ahead and burned the dvd and it also shows up on it, which I figured it would) Does anybody have any idea what could cause this? I just use the defaults in adobe when encoding the mpeg. Is there some kind of custom settings I should use that would eliminate this problem? What really confuses me is it only does it on like 10 pictures out of 100 and the video footage looks great. Very strange! Any advice would be greatly appreciated! Thanks in advance!

Can't help you i'm afraid but why post the same thing three times?

You have a common problem called interlaced induced flicker. The images that flicker probably have thin horizontal lines less than two pixels thick. When the TV scans the video, it scans it in fields horizontaly, if the lines are thin, it only catches them on every other scan and couses it to flicker.

Other things that cause flicker, is an image that is too sharp (never sharpen or use Unsharpen Mask on an image you plan on using in video), or too much contrast.

Take the offending images and run a Guasian Blur @ .3 pixels on them, that will effectively make the offending lines bigger and thus reduce the chance of flicker. If it's only a small area, then you can use a blur tool to blur only the offending area.
