Re: [Avid-L2] Re: Blu ray recorder

 

PsF is a transport protocol and a method for storing progressive frames on tape. Nothing is stored as a file in PsF. Files are either interlaced or progressive.

If you want some progressive stuff on a Blu-ray, feed your encoder a progressive file. If you want some interlaced stuff, feed it interlaced. Blu-ray has no concept of PsF.

My guess is that either Terence is correct, and the player was trying to play at 23.976, or that some players might not be able to output at anything but 25i or 29.97i, so anything that's not 29.97i or 25i will be forced to output at those rates. So 23.976 gets 2:3 pulldown and looks OK in 29.97i, while 24.0 might get a duplicate field every half second (2:2:2:2:2:2:2:2:2:2:2:3) to make 50i. That could be the stutter, as that's the easiest way to make 24 become 25. Try to make 24.0 become 29.97i without changing speed and your head could explode.

What about 29.97 psf.  Does the BD format just tell everybody it's 1080i/59.94?
