Pro Res export time?

[Andrew clemson]

Been asked to deliver dailies as 1080p Apple Prores-HQ. Last time I checked, this wasn't a particularly speedy process. am I being stupid? Is there something I can do to speed up the process? I think my problem might stem from the fact I only take a laptop out when on location. I only take a tower system when in a studio, and then the renders dont take nearly as long.

According to Graeme, use half-high for the debayering from 4k to 1080, that will convert significantly faster and retain the sharpness to the video.

You really need to access the towers 8 cores to create media with any kind of efficiency.

If you use clipfinder to render (it uses redline) then you can specify the number of cores and it will tell you how fast it is rendering in FPS. The average from 4K at half high for DVCPRO 720P is about 8fps.

That sounds about right for half-high based on what our 8-core previous generation Mac Pro tower does.

If you're just transcoding to 720p for an offline, though, you might consider using 1/4 res decoding, which should get you up into the 20-something frames per second range. It looks a little softer, of course.

If they're asking for 1080 HQ it probably means they're going to output the dailies, no online, no going back to the R3D's, etc. So maybe a full-res debayer, though slow, is the way to go. You get about 2 frames a second on a 3ghz 8-core with RedRushes set to full-res, HQ, 2 clips and 8 cores. Half-res high bumps you up to 6-8 frames a second on that same machine, but you can tell the difference between half-high and full. Just do overnight transcodes and be patient...

joe, from my experience and with from Graeme's information, half-high with REDLINE (that means RedAlert!, Monkey Extract and Clipfinder) with OLPF on does special treatment to look sharper than debayering full and resizing to HD.
Try it and compare.

You're right, I tried it and it does look sharper, hmm perhaps one more reason to start using ClipFinder instead...

where does one turn on OLPF in ClipFinder?

Joe, I use Clipfinder to adjust the metadata (so RSX gets saved), then use the XML from FCP in Monkey Extract to render from the XML and the RSX. You can set the OLPF independently in the render setting in Monkey Extract.

In the Clipfinder, the half-high is in the Render/De-bayer Resolution. And the OLPF is set with each metadata (edit look) window.

Thanks Kaku, Monkey Extract is definitely on my list of must-have software

First I thought I could get by with Crimson, then started using Clipfinder, then I found out that Monkey Extract can render only used frames from FCP XML, I had to buy it. Then I was in charge of managing the footage for a feature film then I had to buy R3D manager.

They all help us a lot and serves well for each purpose and I'm feel thankful to each developers.

The workflow I talked about was the exact workflow that I used for the last feature film that I worked for Kadokawa Film. Imagica (the print lab) and the DoP were so impressed with the picture quality.

Good luck to your project joe.
