Re: [Avid-L2] pro res proxy

 

Yes they play in QT.  But Avid wants no part of the files.  I have moved to Premiere as it takes anything easily.  Just have to fumble through to hit deadline.  I am converting a file in Voltaic to DnX just to see what happens but one file takes over an hour so no time to do 4.

Lou,
Just as an FYI, 40GB of ProRes proxy is a lot of video: about 150 minutes of 1080p 23.98fps, or 120 minutes of 1080p 29.97fps.

If that sound like far more than you were expecting, then maybe the files are corrupt. Can you actually play them in Quicktime?

Actually.  I can't even load the AMA file into the source monitor.  Just get spinning  ball and eventually the error.  Could all these files be corrupt?  Could it be an issue with the drive they sent?   Transferring a file to one of my drives for a test.

This isn't necessarily a problem with ProRes Proxy files. It's a problem you run into any time there's a perceived corruption in the source file. If you AMA the file, can you scrub through it in the viewer? All the way through without it throwing up an error? Open in QuickTime player - can you do the same? Does it stall at any point? If so, that is the answer to your issue.

ProRes Proxy as mentioned before is just another variant of the same codec.

ProRes 4444 = ProRes 330
ProRes HQ = ProRes 220/175
ProRes 422 = ProRes 145/115
ProRes LT = ProRes 100
ProRes Proxy = ProRes 45/36

just data rate differences.

Could really use a suggestion here. Im under a very fast turnaround and got the pro res proxy files yesterday late. 4 files at 40GB. I tried to AMA and transcode but keep getting same error. Exception: Failed to get the sample position from the AMA Plug-in.

I tried to import overnight but after 12 and a half hours I got one file. I need to start cutting today. Rebooted linked via AMA and tried to transcode just one file but got the same error. WTF?? Why am I getting this? I have never worked with ProRes proxy files so I'm not in my element here.

Any help would be appreciated greatly.

thanks
Lou
