Batch proxy generate

[david_winters]

Just shot a two day project and want to generate new PROXIES with an exposure and curve adjustment. The changes are global (all R3D files). Is there a script I can write to do such? Or, even better, a GUI method?

Thanks

Hi David,

At the moment the curves and DRX settings will not carry over to the new quicktime reference files generated by Red Alert. I would suggest using the Matrix functions and the contrast, exposure, etc. sliders to adjust your image and make new quicktimes. You will have to take it one file at a time, not aware of any batch ability to make reference files at this point. Also, in Build 15 audio is contained in the qt reference files so make sure you don't overwrite your files if they contain audio (there is an NA appended to the end of the new reference files to protect you from this).

David,

You can use Redline to do it. Here is a little script that will search for your .R3D files and make all size proxys.

for FILE in $(ls */*001.R3D | awk -F "_001.R3D" '{print $1}'); do redline -i `echo $FILE"_001.R3D"` -w 10 --useMeta --QTsize 0; echo "Finished with $FILE" ; done

Just open Terminal

Change directory (cd) into your .RDM directory

run this script

If you want to run this script on multiple .RDM folders change to the directory above the .RDM folders and add another */ to the script like so:

for FILE in $(ls */*/*001.R3D | awk -F "_001.R3D" '{print $1}'); do redline -i `echo $FILE"_001.R3D"` -w 10 --useMeta --QTsize 0; echo "Finished with $FILE" ; done

This should be very fast. You could also insert all your color changes to the script. Where this script has "-w 10 --useMeta --QTsize 0" you could add things like:

Color Space Settings:
-G <int> : gamma curve: lin=-1, custom=0, rec709=1, sRGB=2, REDlog=3, PDLog985=4, PDLog685=5, PDLogCustom=6 [default = 3]
-v <int> : custom gamma value [default off]
-c <int> : color space: rec709=3, camRGB2=9 [default = 9]
-d <int> : detail: leadingLady = 1, medium = 4, high = 8 [default = 8]
-D <int> : post sharpen low = 1, med = 50, high = 100 [default OFF]
--NR <int> : Noise reduction off=0, very mild = 1000, milder = 500, mild = 250 medium = 100, strong = 50, max = 10 [default OFF]
-n <int> : no Matrix [default ON]

Color Settings:
-I <int> : ISO [default = 320, range = 100 to 2000]
-k <int> : kelvin [default = 5600, range = 1700 to 50000]
-t <int> : tint [default = 0.0, range = -100 to 100]
-x <int> : exposure [default = 0.0, range = -12 to 12]
-T <int> : saturation [default = 1.0, range = 0.0 to 2.0]
-C <int> : contrast [default = 0.0, range = -1.0 to 1.0]
-B <int> : brightness [default = 0.0, range = -10 to 50]
-r <int> : red gain [default = 1.0, range = 0.0 to 4.0]
-g <int> : green gain [default = 1.0, range = 0.0 to 4.0]
-b <int> : blue gain [default = 1.0, range = 0.0 to 4.0]
-X <int> : DRX: Dynamic Range Extender [default = .5, range = 0.0 to 1.0]

and much more. If you make your changes in Red Alert and then in the render menu copy to clipboard and paste in a text doc you can see all the settings Red Alert is using to get that look.

Hope that helps. Let me know if you have any questions.


Mahalo,

Thanks for posting this Dusty. Good stuff.

You can also use the automator plug in from anders holck... very great...

Hello

Anyone from RED software team knows if curves and DRX CC will make it into proxies from RA soon or is it something we should forget about for the coming months and either use the workaround (only matrix functions) to edit with '1st light' color corrected proxies ? Else I guess we'd have to process R3D to real QT files using REDRushes or other available options.

Thanks much

Mikael

Yes, should be coming soon (in the next month).

[Mikael Lubtchansky]

Thanks much for the fast answer and the upcoming Ra feature I'll sure be using and enjoying A LOT.
Hopefully with redline we will be able to batch one Rsx into multiple Qt proxies to do 1st light CC on a whole sequence
