As Ben Waggoner mentioned earlier on his post "If you want an interoperable video

All the videos are DVC-PRO interlaced . . .  isn't it important to maintain this for final delivery
to T.V. DVD disk?

I don't think Ben was saying that animation would get rid of a field, I believe he didn't mention it either because he was just thinking about video codecs, or he was concerned about the rgb conversion.

Is it really true that some form of JPEG compression is a better option than a perfect rgb conversion? Doesn't 24 bit color have enough information in it to reproduce 4:4:4?

When it is said that PhotoJPEG is lossless, does that mean in terms of quality, rather than the fact that the original image is reproduced pixel perfect (as is the case with animation)?
