Hi All,

I've just uploaded a new version of LUTCalc and LUTCalc For Mac, and this one really, really should be the last before calling it v2.0. I'm planning to submit the LUTCalc For Mac version to the Mac App Store, so have added a bit more than I intended to make it more flexible / generally useful.

In addition to cube files, LUTAnalyst can now read Resolve 1D iluts and oluts plus Panasonic 3D vlt files. The capability is also there to save in these formats and to add more as I learn about them.

I've also tried to make it easier to get the settings right when generating a LUT. Instead of a Sony-specific 'MLUT' option, you now choose between 'Grading LUT' and 'Camera LUT (MLUT)'. You are then shown a selection of applications or cameras (OK, the cameras is only Sony 3D User MLUT at the moment, but I have the Varicam code in place, just making sure of levels). LUTCalc will then set the LUT parameters as recommended or required and generate a LUT in the appropriate format.

I've added another preview option - this one is a colour wheel displaying the Rec709 colour space. It is shaped like a filled-up vectorscope and is hand to get an idea what adjustments will do overall.

On the camera / gamma front, I have added in a fairly decent stab at the upcoming Canon Log2 curve. I used a chart in the C300mkII introduction video to estimate it. Not ideal, but assuming the chart is correct the error should be less than 1%, and good enough to get an idea pending proper Canon White Papers. Spoiler alert - it looks extremely similar to Arri LogC.

I have also added the C300mkII and Panasonic Varicam 35 to the camera options, basically so that you can compare camera black / white clip levels on the chart.

Lastly, I've got around to sorting out window resizing. If your screen is big enough, you can enlarge the window to avoid scrollbars when displaying the preview and the charts together.

As for bugfixes, there are small ones to the PSST-CDL, basically around interpolation. It should be a bit smoother now.


As ever, feedback is very gratefully received,


Ben
 
Is there an academy award for apps that only serve people in the video business? You've got my vote Ben, and my eternal gratitude for opening up this camera.
Only wish the FS7 User menu would display the name of the LUT ask I don't get confused .

Of you're ever in the San Francisco Bay Area I'd like to buy you a drink.

Thanks Lenilenapi,

I'd love to be visiting the Bay Area - had a fantastic trip there last summer - but sadly not for the forseeable!

Wouldn't you know it, as seems traditional for me, I've found a tiny, silly bug I added whilst being careful over the complex stuff. Basically, clicking over to 1D LUTs stopped working (or at least generating). I've fixed it and uploaded yet another release - 1.9RC8.

Pretty please this one works properly!

Let me know,
