    media composer 3.0 playback freeze on mac pro

    Hiya,

    Brand new to Media Composer, and straight out of the gate I have hit my first snag.  I am having some funky playback issues.  Imported a clip (quicktime) and it plays in the viewer, but video will not play in the timeline/canvas.  In both the viewer and canvas audio playback is fine, but video does not update.  I imported another clip, and video would not play in the both viewer or timeline.  Is this a video card issue?

    I am on a mac pro, os 10.5.4 with an ATI radeon hd 2600 card.  I know avid recommends the nvidia card, but is this required?  Its odd, as Xpress Pro worked just dandy.

    I'm guessing your 'Pro software was pre-5.5.x....

    GFX card requirements went way up after that. Does that card support Open GL and have a minimum of 128 megs of vram? If not, that's were the problem lies.

    I've got the same card and it works flawlessly.  The 2600HD is 256mb.  What kind of drives?

    Here's a few things to try.  First off... what are the resolution and refresh rates of your monitors set to?  Also, bizzare as this sounds, try overlapping the timeline wiondow with the S/R window just a little.  Does that help?  Lastly... what version of QT are you running and how much RAM is in the machine?

    I have seagate drives, the stock 320 that came with the early 2008 mac pro, but my media on a 1 TB.  7200.11 is the model, I believe.  Additionally I have a firewire phantom drive 500 gb.  I am glad that your 2600HD works, I really didn't want to "upgrade" to the nvidia 8800, as it's supposed to be slower in most applications.

    Hiya,

    After work did a reinstall of the MC software.  I should have done this before posting, but anyway it fixed the playback issues.  I was all set to get a Nvidia 8800 @ fry's and test it out too!  Thanks so much for your input all!
