  1. That's a good idea. The Pdf can be a lot to take in for the uninitiated 🙂 With anamorphic, I've wanted to experiment with that for a long time, but have stayed spherical for the time being. I think there are some good complete m4/3 anamorphics now that aren't too expensive (relative to most).
  2. Really nice Parker. What anamorphics do you use? I'm now working on a software that will integrate all steps (WB, Exp, ABL etc) to vastly simplify the workflow (and make other things possible)
  3. Emotive Color V5 'SPECTRUM' The V5 'Spectrum' update is ready. The V5 emails are going out now (let me know if you haven't received it). It is the culmination of four years of engine development, and I hope you enjoy! Emotive Color Component ('EC709') EC709 component (Full/Theatrical) rebuilt with new engine, allowing accurate, uniform far gamut projection of Arri display table Arri Rec.2020 now used as the color target (projected within EC709 envelope); results in deeper saturated red and blue that are otherwise clipped in Arri's Rec.709 High Scale is now Full Scale (unlabeled); a direct replacement for LogC+Rec709, with notable advantages (aesthetics and gamut preservation) New Classic 'Soft' and 'Hype' variations (like V3-era 'Soft' and 'Main') Refined natural saturation model Core LogC Fully realized uniform far gamut projection from known lower saturation samples (solves issue that caused saturated orange to twist towards red) New rolloff math; allows grayscale reconciliation of high saturation brightness values (only available for interpolated .cubes; not achievable in Matrix) Added final, fourth calculation pass (post-smoothing), which allows absolute accuracy to known sample points in final render (while retaining smoothness) Corrected an issue that allowed smoothing algorithm to clash with a 'safety lock' on grayscale hue, that could result in red-green banding near the grayscale (especially with 33x under Trilinear Interpolation); now fully smooth regardless of grayscale Misc. New Ceiling Modifier [POST] files; allows variable highlight compression New 'Natural' profile [PRE] for GH5 (shares settings with Cine-D: -5 Sat, 200 Iso) Remade all PREs (picture profiles / exposures) Revised Pdf; Important: DaVinci Resolve - Enable 'Tetrahedral Interpolation' under Project Settings > Color Management > Lookup Tables (allows 65x performance with 33x cubes; complete gradient smoothness - FCPX has this as default) Remade Premiere PREs with new measurements (to reflect 2021 Premiere's improved codec color); no 8-bit VLog or Cine-D PREs needed Significant revision to Premiere Pdf guide; Advanced layering section is no longer relevant, use Lumetri's luma curve (improved significantly) Gradient Test is now 16-bit png (compatible with Premiere) rather than tif Entire Matrix PowerGrade now printed directly from the engine (complete reverse-engineering of .drx format): Precise values entered directly into the curve interfaces, at maximal point density Improved engine gamma accuracy enables significantly improved base matrices New LogC Exposures feature (true exposure gammas extracted from sample data) New 4200K PowerGrade variant If you have any videos or stills you've made that you can share, I'd love to see them! -Alex
  4. Working on it at this very moment (and a raft of updates simultaneously). Its a generational shift rolled in. I rewrote all code since the last 4.2 update; it's been a very technical winter 🙂
  5. It's a good question; I don't recall there being the same flagging issue. I am in the midst of going back through all cameras for a new update, and I'll test this. The key is, does the LogC variant place black level at 8 Ire, or notably lower (should sit at 8 )
  6. From what I've seen, ProRes Raw is slightly different. I'm planning to get a newer Raw recorder to see if a Pre is warranted, but I think it is usable.
  7. For thoroughly tested LongGOP that maintains complete functionality with pristine imaging, I would highly recommend LPowell's FlowMotion v2. He really did top notch work there.
  8. It does have Gen 5 support - I will be revisiting all G5 profiles after release to be sure that they are in line with the latest from BMD (along with a few other adjustments)
  9. Interesting; what comes to mind is that the latest files allow projection below zero. This only happens in theoretical space (i.e. below legal LogC / VLog), and projects sans clipping (an offset immediately after can bring sub-zero data into view). This area shouldn't be encountered in real footage, so it may be the higher Isos which change the lower data range (S1a is optimized for VLog 640 Iso, 100 Cine-D, 400 HLG). Also, luma grade maneuvers in advance of the Pre/conversion is another way to bring this range into view. I used to have an artificial rolloff to 0 black for theoretical black projection, but this caused problems downstream, so I removed that cap with the latest files. For noise, increased color separation will amplify noise, despite completely smooth tetra interpolation, if the footage has noise macroblocks. Higher bitrate codecs and lower Iso is optimal for clean imaging. Can you send me .tifs of the raw footage to noodle around with?
  10. And to you all - here's to a healthy '21!
  11. @Attila Bakos Very cool, I was on a 3770k; I switched to Ryzen last year for this very purpose. Now I'd like to swap out to one of the newest Ryzens, but they are sold out everywhere. I'm doing something atm wherein I throw enormous amounts of data in, and the renders can easily go upwards of an hour at 100% cpu. My data files are usually around 1Mb per each; these are going upwards of 50Mb atm @zerocool22 CST is a versatile tool that allows whitepaper transforms between any two spaces. These are the manufacturer specified color spaces. Emotive is a measured conversion between two cameras (or profiles etc), such that it factors in sensor response to a light source and internal camera processing (of WB, profile, etc). Emotive has simulations of sensor LogC solely using Resolve color tools (sans CST) called Matrix. Both the interpolated conversions (with Tetrahedral interpolation enabled) and the Matrix LogC simulations are non-destructive, while Arri's Rec709 (that can be added to Matrix LogC) is partly destructive (of extreme Led gamut). CST can be either destructive or non-destructive, depending on the transform specified and relevant gamut. CST + Arri 709: Emotive Color
  12. It must be pre-baked data sets of some sort ('assemble on site'). What Cpu are you rockin'? Yes, with default settings, except set to DR400 (for photos), FLog is preferable for widest gamut
  13. I gave it a spin a few weeks ago; sometimes it works decently, and sometimes less so. Here's a comparison of GH5 and Arri, as well as their gradient charts:
  14. Not yet - I've been on an experimental binge for the last month (not pertaining to the Alex conversions), and I've had a major breakthrough there. But that update will be releasing for sure!
