  Slow framerate playback in Pro trial using Quicktime

  Posted by Shane French on January 9, 2014 at 10:50 pm

  Am evaluating CatDV won Win 7. I’;m having an issue with playback of h.264 files. The framerate is slow (guestimate 12-15 fps) within CatDV. Have tried regular and protected mode player within CatDV, same slow result.

  Playing same files in standalone Quicktime Player works fine, video is smooth.

  Now, I have realized that if QT’s audio playback is set to anything other than 16-bit 44.1, the player exhibits the same issues. Who knows why (of course, the same files play fine in all other apps). Does CatDV force playback at a different audio setting? Could explain the issue I suppose.

  Additionally, playback is smooth within CatDV using Directshow, etc…but it causes VERY frequent crashes (can provide error log if anyone wants to look at it).

  This is a fresh install of Win 7 64-bit. nVidia GTX680.

  Hoping I can get one of the two options working satisfactorily!

  Thanks,

  Shane

  Shane, are the files on a local drive or on a network?

  There are many issues with QT files playing over a network on Win.

  (You might search here for UNC path issues.)

  Hope that helps.

  Hey Bryson,

  Nope, they’re on a locally attached SAS RAID – blazing fast.

  Thanks,

  Shane

  Was this issue resolved? I’m also seeing slow/hitchy playback of h.264 proxies in CatDV Pro 10.1.1 on Windows 7 (not a trial version). The same proxies play smoothly in QuickTime Player, Windows Media Player and they work as expected in the web client.
