Question

Apple pro res 422 file consuming more space than usual

hi everyone!

I've been working with FCP 7 since 2008 and at the same time I started working with Canon T2 from 2 years ago and I haven't had any problems with my FCP workflow files, editing and output used to be H. 264 based files until I started to have problems with my hd DSRL projects. Recently when editing the audio went out of sync and I was suggested to change the Quicktime video settings from FCP 7 to imovie (which is th application I commonly use to create chapters and share to iDVD) this worked perfectly. It was the first time I which I had to change the Quictime Settings to Apple Pro Res 422 The Out of sync problem was resolved but the space consumed by the file was enourmosly ncreased instead. ie. A 5 min project usually would take like a 500 mbs quicktime file and now using the Apple Pro Res 422 this 5 min project went up to 5.3 Ggs!! And also the exporting process is taking forever!! For instance I'm working with a 30 min project and the Quicktime conversion never ends. It's taking about 12 hrs and is not taking more than the 20% of the process. Is there something I'm doing wrong? I need help in a extremely urgent way! Thank you all guys! And best regards from Mexico!!

That's about right for a ProRes 422 file. High quality video takes a lot of space. It's sufficient to use the lighter ProRes LT for the footage from your T2 by the way. Your MacPro can also have up to 4 hard drives for plenty of storage.

Why are you using QuickTime Conversion?

Exporting to QuickTime with current settings and self contained is the better way. Then you use Compressor to make your delivery format from that master. Compressor is faster because it can take advantage of multiple cores - FCP doesn't. It will also give you far more control and choice over the encoding.
