Hello, Does anyone have advice on how to encode an Anaglyph Mpeg for DVD? I understand that Mpeg compression will cause problems when 'sub-sampling' the red/blue colors during compression. The result is ghosting and unwanted artifacts in the compressed video. This has been my experience as well. Only the uncompressed video formats look proper. I have seen movies such as Spy Kids 3D (and others), which successfully transfer anaglyph video to the dvd format. So, there must be a compression method that will avoid the sub-sampling, and still be compatible with dvd standards. Any advice? Thank You & Best Wishes, Chris | ||

No, there isn't. DVD-compatible MPEG is 4:2:0 and that's that. What SpyKids3D did was tweak the color hues in Post so that there would be: minimal ghosting, minimal chroma-based retinal rivalry, and somewhat decent resulting combined-view color hues (some of these being mutually exclusive). What they did was admirable, but I believe it is somewhat futile, compared to viewing, say 120Hz Pageflipped Active system, or even polarized viewing (from side-by-side master, like Sensio). There are also other, better ways that I can't divulge right now, that don't constrain/lock you into formatting your storage/distribution media to the same format as your exhibition type. Look at PuppetKiteKid's articles on "Optimized Anaglyph" for some good pointers on what to tweak before compressing. Scott | ||

Chris, I am having the same problem exactly. Did you ever find an answer? |
