Compressor Render Time = 541 hours?
I recently filmed a concert and am converting all footage over to Apple ProRes 422 (HQ), and I am also converting the frame rate from 29.97fps to 30fps in order to use FCP’s multiclip feature with the other two cameras that shoot at 30fps.
I submitted a job earlier for Compressor to render. It is approximately 4.5 hours of footage when compiled together.
Footage is 1440X1080, 29.97fps.
I DID use the “Best” motion settings under frame controls when converting the frame rate, and I know that that particular setting is often extremely tedious to render, but 541 hours?
Is there any way for me to salvage more processing power from my Mac Pro, or allocate more to Compressor? I read an article recently about using QMaster, but am now unable to find it.
Mac Pro
Mac OS X v. 10.6.8
Processor: 2X3 GHz Dual Core Intel Xeon
Memory: 8 GB 667 MHz DDR2 FB-DIMMThanks.

We’re missing some important details here.
First, most cameras that say they shoot at 30fps shoot 29.97. 30fps is a non-standard frame rate. Your frame rate conversion probably isn’t necessary. Check the media (open it in QT, play it, then hit butterfly+I) from your other cameras. If a conversion is required I suggest converting to 29.97 instead of converting to 30 – even if it means converting more footage.Second, just because ProRes 422 (HQ) has (HQ) after it doesn’t mean it automatically gives you higher quality footage. If this is footage from a DSLR or HDV camera ProRes422 (LT) or ProRes422 would be a better choice – particularly if you’re going to multi-cam without a RAID drive.
Third, yes, you should be able to speed things up in Compressor. Look into setting up a “virtual cluster,” which is using Q-Master. With dual dual core chips you shouldn’t expect a dramatic difference, but it should help. Also, if you transcode from a source drive to a different target drive (not USB) it’ll help.

If the footage really is 30fps you can conform it instantly to 29.97 in Cinema Tools without render.
This may introduce some small sync issues, however (but you would have that anyway using the method you were trying).I would consider conforming everything to 29.97 in Cinema Tools, then use Compressor to convert to ProRes. As had been stated, 30fps is non standard and some monitors won’t even play it.
If you are still having monstrous encode times, Google the utility “Compressor Repair” from Digital Rebellion

When I open it in QT it does indeed say 30fps. How should I do this in Cinema Tools, and will I end up with motion problems?

You are absolutely certain that converting down in frame rate is the superior option here? I have always heard that found so will produce stuttery video. How should I fix the inevitable syncing issues later on?
Thank you kindly for the reply… I am still a budding editor, so I apologize got seemingly nescient inquiries.
