This morning I finally finished the UP-REZ of all the footage. What that means is that all the footage I was previously working with was rendered out at MED-LOW resolution. I then went and re-rendered all the footage out at HI-REZ. I have decided to go into a little bit of an analysis as I managed to come up with some hard stats on the process. Most you will be saying/thinking, "who fucking cares!" and I would tend to agree with you. Except, that is, for the one fact that time is money. Not to mention time taking from my life spent watching the proverbial grass grow.
The figures below are based on the time it took to render out 28 clips shot at 3k (3072 pixels wide by 1728 pixels high). For a size reference go here.

28 clips @ med-low resolution output took 7 hours. So for every 60 sec of shot footage, it takes about 10.5 min to render.
28 clips @ high resolution output took 19 hours. So for every 60 sec of shot footage, it takes about 28 min to render.
So what that means is it takes a fucking long ass time. All these results where using Red Rushes on a Mac Pro with the following specs:

I dont think you will be able to see the difference between the med-low rez frame and the high rez frame but you can click on them to load them up at full size. I have included enlarged segments of the two for comparison. Keep in mind you are only looking at a single frame, 25 of these suckers go by a second so any grain is amplified through the motion of it all.
MED-LOW RESOLUTION

HIGH RESOLUTION

Well I guess you could say my whole point in showing you the difference is that, in and of itself, med-low resolution is still pretty good quality if you are finishing off to HD and if you are working with enormous amounts of footage (like for a documentary) and you don't have 2 months and a few Terrabytes of space in your budget, you could concievable do the whole thing in med-low rez. Of course I would never shoot with a RED Camera and not finish to HI-REZ, it would be kinda pointless don't you think?
(DISCLAIMER: I suck at math so if the figures are off a bit, I blame it on my schooling)
