reconnecting uncompressed files to pro res offline…

Posted by Nina Hirten on April 11, 2009 at 1:46 am

Hi there

I edited a short which was shot on film. I received the footage direct from Technicolour as two HUGE files (each is about 500GB large), both Uncompressed 8-bit.

I decided to do an offline edit, and used compressor to convert the two huge files into Apple pro res files. I did it with a timecode generator at the bottom to make sure the timecode stayed true.

Now, as I’m reconnecting the files, each one is saying that the “media start and end is different.” How is this possible?? The timecode is the same and the files are the exact same length! Anyway, I press continue and it’s horribly out of sync, not to mention that my computer is not fast enough to play through more than a few second of the uncompressed files.

I hate to downgrade quality, but what are my options? Does anyone have any advice?

thanks so much..

Hard drives are very inexpensive (RAID configuration). For this project, get yourself at least 4.5tb of storage. As I mentioned, you will need a fast RAID. No need to work in offline.

This could happen if your offline files were accidentally created with a different frame rate.

As an aside – why were you given uncompressed EIGH-bit files? 10-bit would have been much better quality for post if you intend to use colour correction or effects…

Can you tell us more about the files you were given and the files you created? Codec, frame size, and frame rate are the key pieces of information. If you’re not sure, you can open one of each in QuickTime and hit CMD-I or select ‘Get Info’ from the menu. If for example the frame rates are different you’ll get an error. Say if you converted footage shot at 59.94 fps to a 29.97 offline file.

In any case it will be easier to figure out what happened if you can provide more data.

Hi there

Nope, I exported the Pro res files at the same frame rate (23.98), so that’s not the problem. I even had timecode synced as well. Maybe I’ve just encountered a glitch..

In any case, I have no idea why Technicolour gave me 8 bit, that’s just what I got. *shrugs*

Hey there,

Would be happy to… These are copied and pasted from QT info.

Original files:

Part 1:
-Uncompressed 8 bit, 1920×1080, Millions
-23.98 FPS
-file size: 584.81 GB
-duration: 0:01:45:15.14

Part 2:
-Uncompressed 8 bit, 1920×1080, Millions
-23.98 FPS
-file size: 325.50 GB
-duration: 0:00:57:15.31

Offline files:

Part 1:
-Apple ProRes 422, 1920×1080, Millions
-23.98 FPS
-file size: 118.61 GB
-duration: 0:01:45:15.14

Part 2:
-Apple ProRes 422, 1920×1080, Millions
-23.98 FPS
-file size: 71.84 GB
-duration: 0:00:57:15.31

as you can see… I’m pretty sure that I exported it correctly… Unless I’m totally missing something. But any thoughts are definitely appreciated!
