today I was setting up Silverstak ...
I noticed this .. there are Lut PANAVISON conversion included DXL2 ..

Thoughts on this lut?

Interesting Will do a difference between that and the Ipp2 luts... just to see.

Edit, here:

The cleaner image without the green cast is DXL the other is IPP2 No contrast softrolloff.

Edit again the diagonal split shows the difference.

Quite nice lut I think from just playing with it.

Exact..

THanks for sharing Luigi, do you know if this is a 64x64x64 LUT?
This works the best with Monstro and not other sensors, correct?

My pictures where dragon. Seams to do the remove green tint trick even more for dragon. Don't know what size lut it is.

Though there are many other "DXL LUTs" from Panavision out there, even on a project by project basis, these I believe or the most current cubes for general release.

The general concept of the above is the newer version of Light Iron Color, seen here as Pana.cube. This LUT will work on RED footage from all current cameras. Color-wise it works best on modern sensors from about Dragon on IMO. It was developed for Monstro, but do keep in mind that RED's internal color calibration is alarmingly close sensor to sensor and moderately OLPF to OLPF these days. So yes, you can use it on whatever you want. The the DXL in some ways still is unique in a couple directions, I don't see a major issue using this on current DSMC2 bodies.

Typically Panavision develops a normal and film variant, which you will notice provides different tuning to saturation and even the tone curve itself, though general color is pretty close.

As for the look, I would explore this after VFX related work such as a green screen pull as you can see what it does to a few channels. Much like my LUTs or anybody's, this is a unique though "familliar" themed matrix that pushes the fairly accurate color of the camera to a more "directed look".

luigi do you have the film cube as well. This seams to be the plain one only.

It's not unusual to do two passes in color, one to optimize the green screen to give the VFX artists a chance pull a better key, and then a separate look that optimizes the foreground elements (people, cars, products, whatever). A LUT wouldn't be part of that. We'd give the VFX department both parts, and then they do the composite and give us back the elements for tweaking in final color. In some cases, they provide an external matte so that we can still color-correct the various pieces separately.

I agree that good LUTs are necessary so the crew can look at the image on set to determine if it's going to work, and I have no problem with that.

hehe I searched inside the silverstak program if there is a folder containing the 3d lut cubes .. unfortunately no ..
So the only option was to disable all cdl menus and apply this look to a movie and only then can I export a 3D Lut 33x33.

Thank you for doing this! I'm going to play around with this this weekend. On a side note, who is the subject in the Elevator? They remind me of Angus Scrimm and I wish I could hire him one day!

Luigi thank for the hint! I just downloaded Silverstak and managed to extract a 64 3D LUT for both profiles, I am in love with the results.
Here's a comparison including my usual settings (IPP2 and Anton Esteban's ARRI LUT) and the PANA.cube Luigi provided (which i find extremely close to the DXL2 709 Film).

I don't know if sharing those .cube would be legal or not.

great comparison Man ..
Yes, this lut makes RED cameras even better. out of the box

Sorry how did you extract the 64x64 in silverstack?


a ma sei di Milano siamo vicini eheh

Easy trick: get a 64x64x64 HALD file, throw it on an uncompressed video file and give it to Silverstack. Export the result and do everything backwards. ;D
If you don't mess up with codecs and video space you should have a 100% correct LUT (as far as I know!)

yep, Milano :cheers2:

Good to know Fabio, any chance you'd like to share the 64 LUT file?

Thank you.

I've just tested with black skin tones my end, and love how it immediately takes away sickly greenish cast from my Dragon! I noticed that the LUTs are already 33x33x33 don't know if you can actually "upscale" a 33 lut to a 64 even by using the HALD. However, there is a very easy way to get both LUTS from Silverstack. Simply apply the LUT you want in Silverstack, and then from the top menu go to Export > Looks from Clip... You will get various options , I used REDCINE X PRO (*.cube)

Thanks guys

Is there no way to use this PANA cube in camera with IPP2? Perhaps someone can convert it to a creative LUT rather than a Log3g10 LUT somehow? This would help a lot for getting playback in color and even baked color proxies... Hate having to go into legacy mode and be stuck in log for playback and prores etc. Really like the way it takes away the green/magenta oversensitivity issues I have with IPP2 compared to most other cameras.
