  RED workflow is jerky

  Posted by Jeremy Pitard on November 24, 2009 at 8:41 am

  Hi everybody

  I have a probleme with the RED workflow.

  First… this is my machine:
  Mac OSX 10.5.8
  Two 2.26GHz Quad-Core Intel Xeon “Nehalem” processors)
  8GB memory (4×2 GB)
  two NVIDIA GeForce GT 120 with 512MB
  and 2To in RAID 0 (my book studio edition II) connected in esata to PCI express card Sonnet tempo E4P
  FCP 7.0.1
  and I installed RED FINAL CUT STUDIO 3 INSTALLER from RED website.

  Second… I edit a short movie shoted in 4K.

  Third… When I use the log and transfert window (I tested in native and all pro res) everything is ok… excepted… I can’t read the rushes fluently. It’s jerky.
  And it’s the same when I importe the QT reference movie in 2K or 1K.

  So I don’t know what’s wrong ???

  In the RED website, they says “use a suitable graphic card such as NVIDIA 8800, or ATI 4870”
  I have two NVIDIA GeForce GT 120 with 512MB…
  Can I Have problems if i don’t use a suitable graphic card ?
  Or Have two graphic cards can make conflicts ?

  Does my Hard disk is fast enough ?

  Or it’s my Mac pro which is not powerfull enough ?

  So much questions and I don’t have answers !!!

  Somebody can help me ?

  Thanks a lot

  Jeremy

  Ps… sorry for my english. I’m french 🙂

  cordially

  Alter your RT settings as suggested in the whitepaper for native playback – something like medium or low quality, with full framerate. Make sure external video is turned off.

  If you are not experiencing smooth playback after encoding to prores, I would check your storage connection with a disk speedtest. An internal 3 disk array in your Mac Pro is cheaper and faster.

  Hello Mr Holmes

  Thanks a lot for your answer.

  I configurated my sequence with an illimited RT, a low playback video quality and a half playback frame rate… and It’s working 🙂

  I have an another question for you.

  After the edit… The Production want make the colour calibration to Color in 4K.

  If I importe the 2k Reference QT movies into FCP, I can reconform in 4K into Color
  and if I log and transfert in Native REDCODE… I also can reconform in 4 K.

  So which is the different between this both way ? And which is the best ?

  Thanks a lot

  Hello

  In fact… I imported the 2k Reference QT movies into FCP… and It’s working (even if it’s lighty jerky still)

  but i can’t use the Digital Cinema Desktop Preview (too much jerky)

  So I have question…

  If I add 4GB memory… (I have Already 8GB)… Does it approuve something a lot?

  thanks a lot

  Jeremy
