Analyph photo into DVD

[klode]

Hi,
I want to make a DVD with an anaglyph photos gallery, using the navigation of the menu. I realized that with DVDLab Pro 2 (and with Sony DVD Architect).

I make the same DVD PAL 4:3 project in both software. Then I test this DVD on my LG 47" LCD 16:9 of my living room. After setting the TV on 4:3 show, and after I setting the DVD player on 4:3 too, the image not seem to be correct!

The problem is the images are not anaglyphed on my TV! If I see this images on PC (and of course with the RED-CYAN glasses), I see perfectly the 3D image... But if I put this images into an Authored DVD, they lost the 3D fx. The colors seems not correct, so the lens cannot get properly the relative portion of colored image of the photo. And the image results quitely stretched.

Anyone of you can help me??? I wish to see Mars on my TV!

Try to resize your photos correct, inside a 720x576 canvas. You can do that with photoshop or other image editors

Colour issues are to do with your TV settings, not the authoring. Aspect ratio is to do with your preparation, and not the authoring (if done correctly).

I can't help you, but I did come across a couple of interesting discussions on the difficulty of doing anaglyph in mpeg a while back. Maybe they can give you some ideas:

what does help a little is slightly raising the saturation. After mpeg2 encoding I would notice the 3d clips generally get a little duller than my original uncompressed avi that I was using for anaglyph 3d and therefore would loose the effect quite a bit. Slightly raising the colors (so the red/blue seemed a bit brighter) helped to a degree.

here is a really good example, below is a youtube clip I made of converting a 2d film into a 3d film

1. WATCH THE FILM IN NORMAL QUALITY AND SEE HOW THE 3D SUCKS

2. NOW WATCH IT CLICKING THE HQ BUTTON ON THE BOTTOM RIGHT OF THE VIDEO WINDOW AND SEE HOW THE 3D EFFECT WORKS PROPERLY AND LOOKS MUCH BETTER

and this one

the normal mode on youtube is very similar to how the end clips looked when converted to mpeg2 (no saturation boost). However using the HQ button boost it up close to my original sources that the 3d works the way I want you to see it. I assume this is roughly the same problem you are having and why I mentioned the saturation boost helping out

so try a short test and slightly boost the saturation and see if that helps you at all. Also as others stated make sure you color is correctly set on your tv.

thanks for your supply.

Otherwise, if we make a new matrix for MPEG2 quantization, can we resolve this problem???

Any idea???

The matrix won't make much difference. It's more likely you have colorspace conversion issues. Or you're simply using too little bitrate. Keep in mind that MPEG encoding (like most high compression codecs) stores colors at half resolution. So your 720x480 frame has a 720x480 luma channel and 360x240 chroma channels.

If your source video is interlaced be sure you are using interlaced encoding to keep the chroma channels of the two fields from mingling.
