![]() ![]() ![]() I'm brazilian, here I shoot between all shades and I found 60% a good point (I tested with a color checker too for accuracy). Why 60%? Is a middle point between skin tones. Next time setting your zebras to 60%, if you have a external monitor use false color to match this value and remap all scene. LUTs are just a start point, try color space transform from Davinci for a better workflow, If you use Premiere, try mask skin tone, and match in Vectorscope (in this scenario I recomend Color Checker passport for better workflow). Your problem with slog2 is with the exposure, and bad LUTs. I grabbed your stills and open in Davinci Resolve, just to see what I expect. This can be easily done if OP uses either Premiere Pro or Da Vinci Resolve. Later apply this preset to all clips, much easier and simpler. I feel it's easier to manually adjust a clip within the video software and then save it as an efx preset. generating my own LUTs using the published formulas. I've basically avoided canned LUTs at this point due to the inflexibility, vs. (ffmpeg is more predictable about legal vs. The best results I've actually gotten are by exporting a still frame from a video using ffmpeg, tagging that frame with the appropriate ICC profile (I need to post the actual ICC profiles generated by my hack at as opposed to just source code somewhere so people can use it.), loading it into RawTherapee and editing it to taste, then applying those edits to a level16 HALD CLUT which I then used to preprocess all clips using ffmpeg's lut3d filter. ![]() The problem is that, under the hood, kdenlive would make some bogus full-legal luma conversions because S-Log video is flagged in metadata as being full range (even though it's kinda pseudo-full - it uses values above 235, but the "zero" point for the formulas given in the whitepaper are the legal range definition, e.g. Of course the manual way is not ideal, and you have to check the waveform & vector scope for conforming to REC709 standard.Īs one example - for a while I attempted to use kdenlive's lut3d filter as my LUT. Apply the preset to all the video footages. If all else fail, and the editing software has curves like Photoshop/LR, you can manually tweak it and then save it. Doesn't mean you must stick with a Sony SLog LUT. Many yrs ago I played with a SLog file in Premiere Pro, and you can select different LUT for best match. Could be a LUT compatibility issue between software and SLog2. My footage when the Sony fs5 slog2 to rec 709 utility lut is appliedįirst off need to know what video editing software you are using. My ungraded footage from fs5 - shot in 4k slog2 I am attaching some images to illustrate: A great example can be seen here - this means i know beautiful results are possible. * i know many say the old 8bit doesnt stand up to slog performance, however i have seen stunning footage from the a7sii and a7iii graded w only a utility lut. I have driven myself crazy trying to figure this out! I have even downloaded someone elses footage from the a7iii, used the Sony lut, and it comes out beautiful - just as i would want, so i assume it cannot be a software glitch.Īny ideas on how i can get to the deep and rich colours I often see on explainer slog vids? I am very frustrated - I have tried a million combinations of in camera settings, different exposures, and LUTS - but can never seem to get to a satisfying starting point. The same challenge applies to my fs5 and a7iii footage. It looks as though the utitlity LUT is malfunctioning - although i cannot quite figure out where the problem lies. However in my case, when working w my slog2 footage, when I apply a utility rec 709 lut, my image becomes a blown horrible unusable mess- instead of the colours becoming richer and deeper, they become flatter, yellower, and details are lost. In theory, when slog2 is exposed correctly, applying a utility rec 709 lut should transform the flat desataturated image, into one rich and deep in colour - a great starting point to then finesse a grade. My main issue is that my footage seems to be uncooperative when i am trying to shift into a rec709 colour space. Ive been trying to crack the old slog for some time, and keep running into problems. ![]()
