  It's the compression the HD you watch at home is highly compressed HD. The worst thing to try and compress is noise it changes every frame and eats up bandwidth like a hungry little demon. Fast pans and subtle shadows will show where the math falls apart noise on top of this will be a challenge. HD and Blueray are good but the potential for better is there.
  
  Think that uncompressed HD video takes 190 MBps and BlueRay has a max of 40 MBps. Unfortunately I think that at full 40 MBps. it would lead to an hour of video taking up about
  150 Gigs of space.

  • DVD was fairly tolerable for quite a while despite the even greater compression. - oscar 05:17:37 08/30/07 (0)

    Current HD media gives you more efficient video compression codecs plus more space and bandwidth for the compressionist to work with. Good enough for a lot a people to consider the result "transparent" to the Master video tape (Hah !).
    
    When a better HD format comes out, I'll come a looking. I doubt it's going to happen for quite a while. And when it does, it might be too good. I suspect the Studios will hesistate to release perfect digital copies of their movies to the public.

• PQ can only be as good as the encoding schemes allow, ... - oscar 09:04:41 08/29/07 (1)

  .. the amount of TLC a compressionist is willing to put into it, and the allowable bandwidth and storage capacity available to the HD media. With the same encodes, the movies should look identical for both Blu-ray and HD DVD. As pointed out in the thread, hardware differences and/or calibration issues could be the primary reasons for his issues.

    I agree. Big difference between 5th element and remastered version issued by sony. Format doesnt matter - TLC put into mastering process - thats important. But I will say again I really enjoy each and every advancing format and improvements. Enjoy this hobby - its for FUN!
