Found these first-person observations from this week's
edition (halfway down) summarizing an advanced motion imaging conference interesting.
- Someone reported on a vintage CBS study that the highest average projected film resolution measured from observations in different cities was 875 TV lines per picture height in Hollywood but 750 lines elsewhere. (Believe that multiplies out at 1335-1558 on a 16:9 set.)
- A 1920 x 1080 24p HD "Independence Day" was played at a little over 6 Mbps and appeared 'fine', sharper than a DVD of the same scene.
- Someone from Sarnoff Laboratories reported we're approaching the MPEG-2 limit of visually lossless compression with SDTV at 3 Mbps and HD at 15-18 Mbps. MPEG-4, he said, might provide about 15% more.
