6/7/2023 0 Comments Lutcalc walkthrough![]() kdenlive has a current limitation of 8-bit workflow in all scenarios, so I "bake in" adjustments to the LUT - I usually only do this once per event I record, and it's not really anything different to doing WB tweaks in my RAW converter. I don't have that in my editing software (kdenlive), so I just apply a LUT to each clip. OK, thanks for the clarity - it sounded like you were using an adjustment layer in between your clips and pre-LUT - but the adjustment layer includes the LUT. And since I shoot everything overexposed, this is the step where I drag my exposure down on the individual clip. This does not affect the LUT, but instead allows the original clip to be modified right there on my timeline with the LUT still applied. From there, if I decide a clip needs to be adjusted further, I just click on the clip and make the adjustment in the Lumetri Color panel right there on my clip. ![]() With this LUT applied to my adjustment layer, this means that any clip I drag onto my timeline now automatically has Sony's LC709A LUT applied. ![]() You can find this LUT online for free by Googling it. This LUT was specifically designed by Sony to give accurate color to Sony's FS7 and F5 cameras when shooting in Slog3 / S-Gamut3.Cine, but it works great with Sony's mirrorless cameras when shooting in Slog2 or 3 with S-Gamut3.Cine. In that adjustment layer, I pull up Lumetri Color and apply Sony's LC709A LUT. When I start my project in Premiere, I create an adjustment layer and drag it across the entire timeline, putting it several layers up so that when I drag my clips onto my timeline, they will be underneath the adjustment layer. I shoot everything on my A7SII in Slog2 / S-Gamut3.Cine, overexposing by 1 to 2 stops to ensure a clean image. To answer a question asked on here, I use Premiere Pro to edit and apply LUTs. I think you guys are overcomplicating it a bit. So far S-Log2 has been sufficient for my needs, and I believe it's a better match to the 8-bit depth limit of all of Sony's non-cine bodies. This has led to proper WB being my biggest challenge so far. The one thing I don't like is that it can only sample a single pixel for WB, instead of averaging WB over an area. You can also do exposure compensation and white balance tuning very easy. I've only gotten the hang of probably 5% of LUTCalc's capabilities - it's extremely powerful, but for a basic LUT (such as S-Log2/S-Gamut to Varicam V709 gamma + LC709A gamut - I know I linked the basis for that recently, I think on another post in this thread). Actually in many cases, I just use the camera's own preview thumbnail JPEG for this purpose and it works great. Yeah, I'm a bit confused as to how he is able to even guess at the appropriate adjustments if he's adjusting BEFORE applying the LUT.Īt least for my workflow (which I'm still refining as I'm still learning the ins and outs of S-Log) - I export a JPEG of one frame of my video and then use that as the preview image in LUTCalc, and do all of my LUT tuning there. Looks great! What video editor are you using that allows Sony LUT adjustment layer on to of your timeline?
