Hi everyone,

I'm starting an uprez today, and for the first time we'll do it in-house with MC and Mojo SDi. Now, to be honest I haven't done that for years, and I was wondering if I should go for 2:1 or 1:1 compression. I talked to one of the main Avid house yesterday, and they told me that I shouldn't bother about 1:1 and go for 2:1 instead which will be easier on the harddrives and as good as 1:1.

All my sources are archives, some dating 30 years - though most are between 1 and 8 years old. It's mainly news footage, probably shot on Beta or SP at the time, and often on NTSC converted to PAL. The film won't be effect heavy (a couple of dissolves here and there), but the quality of the original footage will require some cleaning (drop-outs, damage tape, etc). I don't know yet if we'll try to clean as much as possible on the MC (well MC's not exactly a finishing tool) or if we'll take a digibeta playout and clean it at the place where the color-correction will happen.

With all the info I can provide, thanks guys for your feedback and advice!

I'd go 2:1. Here's a good thread for you...

Thanks, great read. For some reason, I didn't find it on a search. I'll go for 2:1 for most of the shots, and grab the one that will be tweaked at 1:1.

You might find that 1:1 results in a snappier sequence, especially as you add effects. I understand that this is because the CPU doesn't have to decode for 1:1 material. Obviously your storage requirements will double.

YMMV

Good point. I'll get the shot that will have some effects at 1:1. I've raided two 500gig inside the MacPro, QuickBench gives me 120Mo/s, that should be enough for 1:1, no?

Should be fine. 10-bit RGB Uncompressed PAL requires about 45 MB/sec not including audio.
