I went into video in general in one of my last posts in some detail and know a bit about the stuff available.

No DVD will hold up on my setup. Most HD sources reveal their inadequacies very obviously on it. 2nd generation Kuro, still going strong after four years, but said to be surpassed by the top line plasmas Panasonic puts out this year, with added gimmicks, but most noteworthy bigger screen sizes and - even better - 120 Hz playback, instead of 72 Hz with 1080p/24 input.

Just to mention something:

There's nothing better than 1080p/24 video from a Blu-Ray.
The best image quality in porn is delivered by Digital Playground this way, as they actually shoot with some of the best cameras abailable; the RED One or a different model from the same company. The Girlfriend Experience was shot on it as well.

Elegant Angel seems to shoot on prosumer camcorders, which deliver good quality, not excellence. Their material looks good.

Elegant Angel's 1080p downloads look pretty good, but not as good as their Blu-Ray releases. It most likely has to do with a higher bitrate, better encoding or both.
The framerate isn't the same as the one it was shot in, I think. It is around 30p, not 24p. This leads to obviously different motion depiction. For those who've gotten used to seeing it displayed correctly, it's said that there's no going back. Some don't see it, know about it or whatever else and don't care. DVDs can't really show the effect. It's there.
