Video freezes, but Audio continues on timeline

Jun 29, 2012 11:07 AM

Tags: #help #premiere #sequence #playback #h264 #freeze #cs6

I'm working on a timeline with a mix of footage. It's mostly MXF files from the Canon C300 (which I used to create a custom sequence), a little bit of 5D, and some h.264 files.

 

I'm having an issue where my timeline will playback fine, but after some amount of time (sometimes 10 seconds, sometimes 3 minutes) the video will freeze, but the audio will continue playing. Timecode will continue to run as well.

 

I have to pause the playback and restart it to get the video to unfreeze.

 

I'd really appreciate any insight. I'd like to use premiere, but I cant even watch back my entire 6 minute timeline at this point without freezes...

 

Specs:

 

Mac Pro 3,1 w/ 10.7.4

 

Premiere 6.0.1

 

2x3ghz Quad Core

12 GB Ram

Nvidia GTX 470

AJA Kona 3 (With latest NDD Driver and Additional Adobe CS6 Driver)

    Is this a relatively long project?  I have a PC project that is about 16 GB of AVCHD that has similar problems, especial if you scrub the timline.  It is with Adobe.  No comments yet

    It's only a 6.5 minute piece, so hopefully that's not the problem.

     

    I forgot to mention that the media is on a Facilis Terrablock Fiber connected Raid 5, so throughput shouldn't be an issue either.

    What happens when you render the Timeline? Do you still get the freezing, or does it play all the way through?

    I have the same problem. It often freezes on the Canon C300 footage, which requires no rendering.

    Have you tried clearing your cache?

    Unfortunately that didnt solve the problem. It seems very random. Sometimes it will happen in the first 15 seconds of my timeline. Sometimes it takes 4-minutes of playback before I get a freeze...

    I have some c300 footage I'll test, perhaps I can reproduce this as a bug.

    Unfortunately I can not reproduce this bug, i've been working with c300 footage for about 2hrs straight and not seeing the video freezing and audio continuing.  Try resetting your Pram, (restart holding command+option+p+r, until the C-chord chimes twice then release.)  I've run into a

    few strange bugs here and there where resetting Pram has usually helped.  Good luck.

    Hi,

     

    I'm also having the same problem with CS4 version.  I'm using Mpeg4 file shot on my canon 60d and it's freezing the video in places and continuing the sound.  The whole clip is just over 2 mins and I don't have any effects at all.

     

    Does anyone know how to solve this please???

     

    Cheers!

     

    Shan

    CS4 is very different... you need to ask in that forum http://forums.adobe.com/community/premiere/premierepro_previous?view=o verview
