What's the average compression ratio for BDVideo codecs?

I've long wondered that. I think the next format should ditch lossy compression.

I also don't know why they didn't go with 720p video and lossless compression rather than 1080p with lossy compression.

Why do most people prefer artifacts with more detail rather than no artifacts with less detail?

Movies in digital format for a theater are about 140-160GB per hour. Blu-ray still cannot handle that level of storage. We are getting there with storage media but not there yet.

If you want non compressed video then you are looking at a single image for each frame of about 60MB per frame.
8.6GB per minute
518.4GB per hour

Theaters use a codec that has no loss but that still only cuts it by a little over half.

A good BD transfer at 1080p on a good, properly calibrated tv looks damn good to me.

Thanks🙂 They should just go with 720p and lossless downloads then.
