ProRes LT to H.264 in Compressor - How to reduce compression times?
on Jul 30, 2011 at 1:32:55 am

I am compressing a ProRes LT 720p30 sequence to H.264 using Ken Stone's vimeo settings:

http://www.kenstone.net/fcp_homepage/vimeo_hd_compressor_douglas.html

The only changes I have made are:
Data Rate: 2500 K/Bs
Streaming: Fast start

I am using MacBook Pro with 2.66Ghz Intel Core 2 Duo, 4GB RAM

I also send the sequence straight to compressor from FCP.

40 minutes of video takes around 5 hours to compress.

Does anyone have any suggestions on how to reduce compression time?

What are the limiting hardware features on compression times? Is it CPU/RAM/GPU?
Would compression times be greatly reduced by buying a beefy Mac Pro?
Any word on virtual clusters? Or even networkingmultiple Macbook Pro's to use as a cluster?
I have had mixed advice on exporting from FCP and then importing to compressor rather than using the 'send to' function - I am in the middle of a job so don't want to experiment with my workflow at the moment.

Thanks,
JH
