haha, sick

1)cut realtime via th QT wrappers (created by redalert) in FCP, or transcode the wrapper files to a off line codec in quicktime or FCP MUCH faster than doing it in REDCINE.

2)then export a XML via FCP,

3) Import that into AE (via fcptoAE from: here)

4)Then manually go into RedCine and create a pull list of my edit

5) render from redcine at 4k

6)import those clips into AE

7) replace the existing LQ clips in the AE project, change project settings to 4k etc.

8) drink beer

Most of this workflow could be automated with a little applescript/perl/tktcl/cobalt/whateverscriptyouwant. The only thing that holds this back is REdCine's understanding of a pull list.

This can be worked around by making a small program that would refrance the r3d files listed in the EDL/XML then 1) set the metadata of the r3d to the in/out listed in the EDL/XML then 2) move them into a directory by themselves. That way RedCine could jut import the directory.

Speed Tests:

NOTE: For both systems the test .r3d file was located on our local RAID- via gigabit connection

Test File: Jim's 4K Dragster footage (236 frames)
Output: 1080P 10 bit DPX files
Write files to desktop

System 1-
Windows XP
2 x QuadCore Intel Xeon X5355 @2.67Ghz
4GB RAM
Quadro FX 4500 (latest drivers, Oct 4th release)
Close to realtime playback at "1/2 HIGH"

RENDER TIME: 2:43


System 2-
17" MacBook Pro

Here are the RedCine settings if you want to compare:
slight s-curve
contrast 1.1
exposure .46
Color ]
5.781
0.000
-2.522
Kelvin- 6700
saturation 1.1
10-bit DPX 1080P

Great, thanks for that comparison! Sounds like most users are going to need a dedicated computer that handles all things render within RedCine. Luckily PCs are relatively cheap to assemble so that shouldn't be a big problem.

Thanks Mike for the rundown.. I'm going to play with this..

A macbook pro will always be slow when processing 4K footage, sorry. It will get better when we optimize things, but it's a lot of data to push around. If the new macbook's are nvidia indeed and the Apple driver has not been "fixed" then I have to advice to not use it for 4K rendering in REDCINE (which you probably want to do on an 8-core with a proper raid system anyway).

2K and lower should be fine (but keep in mind that REDCINE will do a full 4K decode and then downsample that to 2K when you're outputting high quality, so it will still have problems with the nvidia slow down on OS X)

[Greg M]

I never expected the MBP to be fast...actually I am very impressed with the performance overall. The 8 core system is pretty respectable.

what about automtic duck? do you see any use for it?

[Mike Prevette]

AD Is a great program, I've worked with Wes Plate the creator of it a few times here in Seattle. In this instance it wouldn't be doing anything RED specific, it would just be doing what a free script can already do in number 3 of the list above. Since this is an offline edit at that point the complex conversions that AD do wouldn't be utilized. AD is a GREAT product and i highly recommend it, but in this case it wouldn't be helping you out to much.

[Jay A. Kelley]

My goal is to be able to take a 2k REDCode file, then output/downconvert it to 1080i or 720p or 480i.

As I understand it, only quicktime is available.. But I would sure love some windows formats in this (Like uncompressed AVI for SD).

I will have my fun, but this is what I will need to make money

RENDER TIME: 12:40

is that 2 hours and 43 minutes or 2 minutes and 43 seconds?
