Has anyone tested the FS700 Slog2 LC709a LUT already?
For me it looks a little bit weird with a shift towards green/cyan also in 7Q preview and in NLE/Resolve too.

But anyway a big thanks for adding this feature for free!

First of all, to Mitch & CD: Great Scot! ;-)

I had the same thing. So, I intentionally used WB off by 200K, and it worked. I may be wrong, but this shift towards green is an FS700 issue. Right?
 
I have a great problem.
If a normal Slog2 to 709 Lut brings the 32% to 45%, why does the -2 Stop Lut brings the exposure down. Wouldnt it be right if this LUT wouldnt do anything about exposing because 2 Stops over exposure is 45% and thats already right, so the LUT only has to expand contrast and remap to 709 space.
Now what the LUT does is if you expose to 45 it goes back to 32 and thats senseless.
Additional i found that the -1 stop LUT is about 1/3 of a stop and the -2 stop LUT is about 2 1/3 stop.

I don't know what you mean with WB off? It also looks weird in resolve with the .cube LUT but without the LUT you get a nice image either by manual correction or by match with the color chart. There was no need to fiddle with WB or color temperature

View attachment 101724got some problem using Odyssey-Additional-Preset-LUTs-MAY2015...

I converted the cube to cdlut, and add to ssd, i saw this result in 7Q preview my old footages.

Build in Luts look normal.

Thanks

Did you get a reply from CD? I'm seeing the same thing. I converted on a Mac. First time I did it the first 6 LUT's showed proper but the name list in Odyssey was empty. I tried again a few times and only see this (pretty cool I must say) psychedelic effect.

Another problem: why are LUTs clipping in extended range and in legal range its not?
Click to expand...
Extended range mode takes the signal from the camera, expands the 64-940 range to fill the entire 0-1023 range, applies the LUT, and then shrinks the 0-1023 range back to 64-940. So anything above 940 in the original signal will be clipped off by this process. This is done to mirror what happens in Resolve if you read a ProRes file, apply a LUT, and render a ProRes file.

Legal range mode just applies the LUT to the signal "as is".

It is complicated, and the terminology is potentially confusing. Have you read the section on LUT Ranges from the article I wrote for the CD Knowlegebase?

Because that is what it was designed to do.

Shoot at e.g. T5.6, then open up two stops to T2.8. Apply the standard LC709A LUT to the first clip, and the -2 LC709A LUT to the second, and the image should look the same, except there will be less shadow noise in the second image. You over-expose in camera, and the LUT brings it back down, reducing noise.

...or, you could, just as easily, expose the LC709A LUT to set white at 90%, then apply the -2 LUT in post. Same, same.

I am slightly confused by your numbers. The standard S-Log2 to LC709A LUT does not change 32% to 45%. It changes it to 39%. Are you sure you are not using the Rec.709(800%) LUT, which does take 32% to about 45%? The minus 1 and minus 2 LUTs are not based on Rec.709(800%) they are based on LC709A.

Also, are you saying that if you open up your iris by two stops, a grey card which was previously reading 32% in S-Log2 now reads 45% in S-Log2? This should not be the case. I don't have a camera here to test, but opening up the iris two stops should take 32% to 55% in S-Log2.

But if you plan to use the -2 LUT in post, why not use it while you shoot. Otherwise you are looking at an over-exposed image while you are shooting. I would always suggest that what you look at when shooting should be a preview of what you intend to do in post.
 
Great stuff!

Installing the firmware. I just purchased the M31 Cinema 3d LUt. How do we install it onto the 7q?
 
Really looking forward to using this update. This might be an easy question, but I've never used the REC 709 (800%) before with the Odyssey 7Q. Is it as simple as just going into any Picture Profile and changing the gamma to that?

Also, include me in the list of those who would love to be able to bake a LUT into the footage. So often I hand off Slog2 to clients only to see them butcher the grading. It would be so nice to give them a finished look that couldn't be messed up (this is why I'm interested in experimenting witht he REC 709 (800%).

Guess I've never learned to trust a viewfinder, preferring zebra and histogram/wfm. And with this release of the firmware, it's possible to have a million different ways to view the scene, but, still have the zebra and waveform unaffected. Perfect combination for me. It's always possible to have a LUT applied, in-camera, then mistakenly double LUT the image on the O7Q. No, for me, there's too many chances for error by relying on a VF.

Art Adams has a pretty good write-up on exposure if you use LC709A as a VF LUT here:

Great stuff thanks to cd!
Not so interesting for our productions.
We've been waiting for the promised fs700 prores 200/240 fps feature and are totally disappointed now.
When will this happen?

Were this banding issues only in log2 or in rec709 as well?
thanks for a reply.

We will post a new forecast shortly. "Cause we've done so well with them in the past! ;-)

Banding issues were with any RAW output and have been addressed as such.

Does that mean that we should only shoot 3200K or 5600K? Because in some situations i shoot 4400K in mixed lighting situations, or live concerts...

No, it means that you should try to adjust your white balance when you shoot to something vaguely close to what you want it to be in the end. Whatever that may be is fine, just try to get in the ballpark.

Hello Mitch!
any words about the samsung evo 850 compatibility and handles?
thank you!
Click to expand...
We will have a new forecast soon. The handles are actually available for purchase now through our dealer network. We sell them in packs of five with the necessary screws and glue.

Think I'll let Nick Shaw respond when he gets a chance. He wrote those LUTs.

Edit: I see Nick already responded. I should really read ahead.
