I'm looking for help from anyone who has used Tmpgenc Plus. I'm trying to transfer an interlaced clip onto DVD using Tmpgenc Plus. There are two short scenes which contain intense red objects. After the mpeg-2 compression (it doesn't seem like typical ghosting) the left-eye image is "burnt" onto the right just for that object. Any advice on how to remedy this would be appreciated.

Proper interlace setting in TMPGEnc will not cause color bleed... my guess is it is either in the original movie or the ghosting is caused by something else:
Recheck your settings in TMPGEnc and make sure you have the "Interlace" options on.
Load the original movie (before conversion to MPEG 2) in VirtualDub and "deinterlace to side by side", then look for the color bleed.
Load the resulting MPEG 2 in VirtualDubMPEG2 and "deinterlace to side by side", then look for the color bleed.

When I load the movie to Vdub and deinterlace the images before the conversion there's no color bleed at all. But after the conversion to mpeg-2, there is definitely bleed apparent. So I'll have to check the interlace options in Tmpgenc. Any recommended settings? Thanks PKK... you rule.

I would do this is two places:

In TMPGEnc,
1) go to "Setting" > "Video" > "Encode Mode" and choose "Interlace".
2) go to "Setting" > "Advanced" > "Video Source Setting/ Video Source Type" and choose "Interlace".

If you still have problems, upload one frame of the original and the same frame of the MPEG and maybe I (or someone) can identify the problem.

The reason for color bleeding can be both the encoder and the decoder. If you've configured Tmpgenc properly, the problem is caused by the decoder. Most software decoders decode color information improperly. Here's an example from Slingshots's Haunted Castle 3D-DVD:

Correct output (PowerDVD):

Incorrect output (Moonlight-Elecard Decoder):

Ok... the problem wasn't TMPGenc. I'm using StereoMovie Maker to join the left and right images of the movie after refining them in Vdub. I've been using the XviD MPEG-4 codec for video compression in StereoMovie Maker to save the interlaced stereo movie. Ater I join the left/right images to interlaced mode I get the color bleed (I checked them in Vdub with fields unfolded side by side). I've tried all the codecs and only when I save the file uncompressed do I get the result I need (no color bleed). Any suggestions? Thanks.

Aha. I figured it was something simple like that :-)
You are correct. Only uncompressed or lossless compression will retain the field integrity.
I use HuffYUV.
http://neuron2.net/www.math.berkeley.edu/benrg/huffyuv.html
It is one of the only lossless formats for the PC, and is the the only freeware one, I believe. The file sizes are still rather large, but much smaller than an uncompressed AVI.
The only other good solution is to frameserve directly from VirtualDub to TMPGEnc and encode an MPEG 2.

Hmmm. I guess I shouldn't have said that "only uncompressed or lossless compression will retain the field integrity." Obviously, there are a few (but not many) lossy options, but HuffYUV might be your only option (or one of very few... and probably the only free one) for rendering from StereoMovie Maker. I would definitely use HuffYUV or create the interlaced conversion in VirtualDub and frameserve to MPEG 2 with TMPGEnc.
I have seen an MPEG 2 codec (AVI wrapper) that you could access from SMM... and there's a lossless MJPEG codec... also DV might work, huh? Just remember, if you want to make a DVD, it's not a good idea to recompress... i.e., it's best to go straight from uncompressed or lossless to MPEG 2.

Hey... how about that! HuffYUV did the trick! Thanks guys.

One more quick note. With my fast computer, I can even view HuffYUV video in real-time without dropping frames (normal rez... I haven't tried hi-rez), but it's really useful for archiving (keep that codec! :-) or transitional editing/encoding (like SMM to TMPGEnc).
So, you could use it for things like progressive anaglyph or lossless field sequential 3D "shorts", avoiding lossy compression artifacts...
It was originally developed for analog capture, but I think lots of people still use it for these other purposes.

Geez I wish I would've know about it sooner. Thanks though... it works perfect. Very nice results.
