  Video Level drop

  Posted by Leigh Jewell on July 8, 2005 at 8:49 pm

  I don’t know if anyone has experienced this or even if it is a Kona2 problem – I don’t think it is – but I was hoping someone might know of a solution.
  My main problem is that stills saved from Final Cut have dropped gamma levels. My main test for this has been to use Final Cut’s bars – though I have also used other footage and had the same problem. I export the frame as a file then open the file back up in Final Cut.
  Specifics: It doesn’t matter which type of file I use – Targa, TIFF, PICT. If I save the bars as a movie, open it up in Quicktime and save it, the levels are only slightly dropped. The same movie, exporting from After Effects, slightly more of a level drop than Quicktime.
  We are also seeing a level drop when going from our Mac workstations (both identical setups) to the Avid Symphony. It doesn’t seem to matter what codec is used.

  We recently upgraded to a 2.5 GHz G5 with the Kona2 card. Running OS version 10.3.8. Final Cut Pro version 4.5. Quicktime 6.5.

  Thanks in advance for your help.

  Most of the sequence settings in FCP are YUV not RGB, so when you send clips to AE you are converting the color space to RGB. This is probably why you are seeing a shift…
