  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Red Gamma / Color questions

I guess a simple way of explaining it would be:

The image sensor in the camera records brightness values as linear data and you need to apply a gamma curve to that linear data to make the contrast look "right". Redgamma 1-2-3 are gamma curves where the aim is to make a usable image right out the bat, 3 being the latest version of the curve. They're essentially best used when you're finishing in REC.709 and arent going to do much color grading.

As a side note: Redlogfilm is another gamma curve and its aim is to deliver an image that is suitable for log grading (which delves from the fact that scanned film footage usually comes in with logarithmic gamma).

Redcolor is sort of the same thing: make the data of the sensor into a visually pleasing image, but it only applies to color. And Redcolor3 is again the latest version.

EDIT to add: For more on log gamma and grading, check out Mike Most's blog. What Log Is... And Isn't and Understanding Log Grading.

Of sorts, yes. It's a way of interpreting the data from the camera.

I would assume the flat image you mean is Redlogfilm.
 
Usually anytime a log curve is used, the image will appear flat - this preserves maximum amount of detail in all the brightness levels of the picture, knowing you are intending to spend time/money in post on grading, so that the detail is there to be pushed around. The log image is not intended to look right while you are shooting it, although you can apply a local look (LUT) on top of the log image for viewing purposes (if you have the required types of monitor/outboard adaptor box, or a setting in the camera) which saves nervous clients from worrying during the shoot.
 
AFAIK you need Sony Vegas Pro 11 to handle Scarlet files (Vegas 10 will not do). I think Vegas does not yet support redcolor3
 
Hey guys, im sorry to dig this thread up, but i have a problem. So after doing a nice grade in RedLogFilm over in Red CineX, i save as RMD, then import it into vegas, it looks too contrasty. Just like when i change the settings in RCX to be RedGamma 2 or 3, after grading on RedLogFilm. Since there is no way to change the gamma settings (only color) in vegas red importer, i dont know what to do. Any suggestions? Apart from grading in RedGamma 3 since it doesnt look as nice ;)

I would recommend using Redgamma3 and Redcolor3 especially if you are grading in RCX. IMHO RedLogFilm would be for if you were going to render out to something else before grading and wanted to save as much info as possible. Since you are grading the Raw footage I don't think there is any reason to use the RedLogFilm.

My guess is that if Vegas doesn't give you an option it's interpreting the footage with Redgamma/color 2 or 3.

Ok thanks. Looks like the way ill have to because thats the only way it works haha.
 
I agree that grading in RCX will end up being the easiest route. Redcolor/gamma 3 represent the latest color science setttings developed by Red. 1 and 2 are still available, and still preferred, by some, but I would roll with 3. I have never used Vegas, specifically, but lots can go wrong with xml files, and, in my case, in the past, have had issues with exporting proxies to FCP 7, back to RCX to connect to full res, then back to FCP then out to Apple Color for grades..you get the picture.. There is an enormous amount of flexibility in RCX IMHO, and with the right curve, you can pull out alot of contrast (depending on lighting) and fine tune it quite a bit. I've grown to like it as it keeps me more focused on how I lit my shots, what the camera can do etc. as opposed to spending all of the extra time bouncing back and forth between programs..best of luck!
