Hi everyone,,My first post to here and I am rather hoping you can stop me from pulling the last vestiges of hair from my scalp.

I have been working with 3ds and max for a very long time. However, usually for informational promotional CDs, web based movie or print. Now I am in a position where I need to create DVD material of land development, golf courses etc.

For better or worse, I chose to render from max non-interlaced Targas at 853x480, 16:9 square pixels. I figured that maintaining an actual height at which DV1 would finally render it out, I would save generation loss. Now bringing this material into Premiere and exporting the movie to a 720x480 16:9 format I get the most horrible verticle lines that look like bad antialiasing in the width compression and also terrible undulation in the land surface of my scenes. Non of this of course happens if I encode to wmv for DV or any other use.

I have been reading that there is a problem with the MS DV1 codec, is this relevant to my snags or is there some other reason for the problem.

By the way I also chose to render at 853x480 for another reason, my frame render time is almost 8 minutes and would have gone up seriously if I had rendered at 1280x720. I am in the process of installing a render farm so I should be able to upscale my render size then.
I did try rescaling the targas at 1280x720 to another directory through premiere with no compression etc and it still makes the same terrible mess.

I did another 600 frame pass last night (reduced poly) at the proper resolution of 720x480 with a pixel aspect ratio of 1.184 and this morning I tried this in Premiere and get the same terrible lines

Save me a visit to Bosley Medical anyone :-) ??

thanks Paul

I think you should visit www.vcdhelp.com (http://www.vcdhelp.com) and ask someone there, I´m sure that "the guys" around there can save your life!

Curious have you tried using after effects or combustion instead of premiere? You have alot more control over your footage.

I tried to replicate what you trying to achieve with a simple test scene and have been unsuccessful. What version of Premiere are you using?
Are you project and export settings correct?

well, now here's a thing, just to prove to myself that the snag was real I just, 30 minutes ago, burned a CD of the sequence and lo and behold, voila, no lines. It seems that SP2 strikes again somehow, because looking back at material I did before the artifacts showed up, they also now have them.

I thank you all and kick myself for not going to a dvd burn earlier.

anyone got a use for a pile of grey hair ? :-)
