Can anyone help with this, I'm exporting my timeline to a Quicktime .mov, my video is roughly 49 mins long and was shot at 1080P. When I export it reaches 00:48:44: mins out of 08:28:00 roughly then freezes. At that point Media Composer just hangs and then crashes. I'm running on a HP Z400 quad 2.93 with 8G of ram and using Quadro FX3800 video card. Checked all the specs and configs, trashed user profile, confirm Quictime 7.7.1 running, any help would be gratly appreciated. Need to get this video out to my clients.  

Do you not have some external program with which to encode your export, such as Sorenson Squeeze?  Most editors shy away from straight QT exports out of Avid, given Quicktime's history with gamma shifts and the length of the export process.  I don't even want to think about how lwrge a file a 49 minute 1080p Quicktime would be.  

Most commons workflow is a Quicktime Reference export out of MC, then encode with Squeeze, Media Encoder, or other.

 

What type of Quicktime are you trying to export?

I am not understanding this

but you say your movie is

49 mins long

Is your timeline made up of "AMA" linked media?  Or is it Captured footage or Imported media?

I interpreted it as meaning that out of a total export time of 08:28:00, it crashes at 00:48:44.  I think he's trying to export a straight Quicktime.  Hence the lengthy export.

In which case I would do an audio and Video mixdown and edit these mixdowns into a new sequence.  If either of those mixdowns fail to create it could well indicate why the original export fails. (Mixdowns are relatively fast to create and easy to delete if you need to free up some disk space after the client has received their video.)
Then as you said export the Mixdown sequence as a QT reference file (almost instant export as it just references the mixdown media you just created) and use a third party encoder.
