Tearing issues in Premiere CS4 export

[MadScientist]

Hey everyone, I dunno if you can help me or not, but here goes.
I just switched over to CS4. I finished an AMV that I am submitting to a contest, but I seem to have an issue with exporting the video from Premiere. I have tried both DV and regular AVI uncompressed but the video seems to always have tearing, especially during the transitions. I have kept the source footage at 23.98 fps and always exported at the same framerate. I don't know why I keep seeing it. When I run the video through Vdubmod, and move from frame to frame it does not show actual tearing, just when I hit the arrow key to progress to the next frame it shows a horizontal break in the frame for a split second. So is it just a refresh rate issue I keep seeing, and not actually in the footage? Its driving me crazy since I can't figure out the cause.

This would seem to indicate that your video card is to blame (or perhaps your hard drive or processor, seeing as how you're dealing with very large files here -- does it still show up if you compress to something distributable, like XviD?). If the actual frames themselves are showing up all right in VirtualDubMod, then you should be fine.

If the issue still is there in the final encode, because it actually is there in the export, then it might be due to the effects you used. I know for personal experience that using the twitch in premiere will cause tearing upon export, no matter the codec (it exports fine from after effects, tho). This might have been due to the fact that I am using e beta version of premiere, but I feel like pointing it out in the case the issue is still there in the final too. Some other external plugins might be causing such issue, so try to export without those and see if you can add them in after effects or in some other way.

Well ultimately I needed to run it through AE to put some final effects on it with some adjustment layers. So I ended up turning on the frame blending on the video layer and it seemed to stop it. So I am not quite sure what the cause was, but i seemed to get rid of it so I'll have to pay closer attention next time.
