  Squashed & frozen playback within Prem Pro CS4

  Posted by Graham Macfarlane on July 16, 2010 at 9:25 pm

  When I render a preview within premiere Pro CS4 to watch my edit in real time the playback is squashed down.

  I’m temporarily stuck on an old machine (AMD Athlon 64 X2 Dual) (running XP 32 bit because the GeForce 7800GT messes up under a 64bit OS).

  I cleaned out all the old preview files and checked the scratch disks are pointing to a nice fast empty HD but it doesn’t help.

  I tried fiddling with the Video preview options in the sequence settings.
  In the codec list at the top there are three DV options and all of these cause the squash issue.
  Other codecs I tried:
  * Intel IYUV: Doesn’t squash but also doesn’t play back real time
  * Microsoft RLE: Doesn’t squash but looks horrible (colour banding)
  * Microsoft Video 1: Same as RLE
  * Uncompressed UYVY 422 8bit: No squash but not real time (data rate too high)
  * V210 10bit YUV: No squash, looks acceptable but frame rate is very slightly choppy.

  It would seem the last codec in the list is the one to use.

  Unfortunately I also found that some elements in my edit (which are from MOV sources rather than image sequences) freeze up and do not play beyond their first frame. At first I thought this was another issue with the previewing in premiere but when I did a full render output the result is the same. They all worked perfectly on Premiere CS3 on the same computer.

  I heard from Vincent Rosati on the Cow forums, that some older CPUs (Pre SSE2) are limited to CS2 for some of the Adobe applications, however I believe my CPU can manage SSE3 instructions so it shouldn’t be a hardware problem.

  Thanks for any help,
  Graham
