  1. I haven't seen this problem in 15.3.1 on Mac OSX 10.14.5, either with the Mini Panel or the Advanced Panels. How many nodes? What specific hardware are you using? I typically use anywhere between 15 and 30 nodes, but there's a lot of "it depends" in there. I do run with quite a few nodes bypassed when they're not needed, but I certainly do a lot of enable/bypass actions when I'm doing a trim pass.
  2. Another thing you could do is qualify a key on upper-mids and highlights, soften it to reduce artifacts, add a little NR, and desaturate there. The effect is different than a Lum vs. Sat curve and (to me) not as destructive if you're very careful. I do this all the time when I need to subtly go in the opposite direction and desaturate blacks without artifacts. But I try not to push it too hard. Noted DP Steve Yedlin has some things to say about the "film look" and digital cameras, and he has some interesting theories and conclusions: http://www.yedlin.net/OnColorScience/
  3. Another recommendation for PixelTools: they did a terrific job at assembling together utilities, often-used nodes, and looks in one package. And unlike a LUT, they can be adjusted to work in any color space and camera format.
  4. I would point to the Oscar-winning film The Artist as an example where they not only digitally created "halation," but they went a step further and made modern 35mm color film look like 1920s B&W nitrate film. That's a very clever trick, and I think it helped sell the look and period of the film very well. Only Richard Deusy as Duboircolor in France knows exactly how they did it, but I think you can bet there were carefully-qualified keys, a glow filter of some kind, and some blur here and there. Great lighting and filtration in-camera probably helped as well. It's a great-looking film -- all shot on film, but (ironically) done at Red Studios on Cahuenga Blvd. in Hollywood.
  5. BTW, here's an interesting interview I missed a few months ago where Stefan was part of Panasonic's introduction of their new GZ2000 OLED display: This is the longest I've ever heard Mr. Sonnenfeld speak about anything.
  6. Stefan doesn't give many interviews, but he did chat with Steve Hullfish's book The Art & Technique of Digital Color Correction, and I found a lot of what he said enlightening. My take is that Sonnenfeld works very quickly and uses simpler techniques than a lot of people suspect. He does extraordinarily good work, and there are few other people in Hollywood (and everywhere else) who grasp the importance of client relations, sales, business, and technology and have the ability to balance all of them the way Stefan Sonnenfeld does.
  7. Yes, you can grab a still frame of the "good" image and then paste that within the keyframe area and that should recall the keyframed color correction. You have to kind of figure out a strategy for dealing with color fading. To tell you the truth, I don't think Resolve (or Baselight or Lustre or whatever) is the best tool for that job: you'd be better off doing kind of a "best light" and then sending the files through an MTI DRS or a similar restoration system just to "stabilize" the color fading, and then take those files and color correct them for a final look. The problem with film color fading is that it's non-linear, meaning that one side of the image is going to be more faded than the other, so you could wind up having to use a lot of power windows and masks on top of the keyframe issue. The labor involved would be ridiculous, to the point where it'd drive you mad. One thing I know that Lowry Digital did back in the day (when I was there around 2010-2012) was they would break the image down into RGB, then process and reduce the flicker and fading on a channel by channel basis. Once that was done, they would merge the RGB files back together again. That may be more complicated than what you want or need to do, but it's interesting to note that generally one channel is flickering or wavering more than the others, and that might give you a clue as to how to attack the problem.
  8. No, in Resolve the RGB Mixer has a completely different function. I tend to use Offset very early in the grade (usually followed with a Custom Curve), to get a broad overall adjustment, and once I get the image in what I call "quasi-Rec709 space," then I can start making more precise balances. I tend to use Pots (individual RGB controls) in the Primaries to start the adjustment, but you can make a good argument for other methods. I sometimes work with film-based projects where there is no Raw data per se (that is, no Raw adjustments), so sometimes I'll use either the RGB Pots or sometimes the RGB Mixer to fix color temperature problems. In particular, it's helpful if you have an underexposed Blue channel, and you can "steal" some information from R&G to give the Blue a cleaner signal to work with. This will help minimize noise in cases where the Blue channel is underexposed. There are a lot of different ways to work, and the beauty of Resolve (or Baselight or Mistika or any top-flight system) is you can choose one of a half-dozen different methods. As long as it works, the end justifies the means. I do tend to start with a very well-balanced picture first and then degrade it later on if we need to go to (say) an extreme blue look or a bleach-bypass look. I'm not a fan of starting with an image that leans off to one side early on in the signal chain, because the danger is that later on, you can wind up with distortion and noise because you're overdriving the signal (or worse, destructively crushing the signal and then being unable to normalize it in subsequent nodes or layers.
  9. Yes, Dan Moran is very good. (He's also of normal height, which I like.) I don't often get into "beauty grading," but most of what I know came from Dan's lessons, and they helped me immensely on a couple of projects. Dan also had some great ideas on how to mask and track complex objects, which boiled down to multiple shapes -- and that was a good lesson to learn. MixingLight is a terrific resource.
  10. Naw, we go with just the 2-up Display at the moment. It's been fine. It's rare I ever go beyond 25 nodes. 18 is more normal for the way I work. There are always exceptions: a few weeks ago, I did a 90-minute documentary in 12 hours in 5 nodes, whole thing, maybe 900 shots. It's more a time/budget exercise, not "how many nodes can I make?" The wide displays give me a headache because I'm breaking my neck on the keyframe window. I also like breaking out the external scopes to a 3rd display.
  11. You could also paste the clip on a dedicated timeline on the edit page and just repeat it over and over and over, with a fixed Composite Level and setting. There are pros and cons to either approach. Note you can also color-correct the grain to intensify it or reduce it.
  12. Walter is a very bright guy. I also use a fixed node tree and (because great minds think alike) I also have preset Left / Center / Right masks when needed plus a vignette. One thing I got out of this was I've always had a TRIM node at the end for client trimming, but at Walter's level, he needs a DP Trim mode, an Exec Trim mode, and a Director Trim mode, which I had never thought of. That's a clever idea. Walter has said many times (so this is no secret) that it's very important to get a solid "balanced" image early in the image chain, and that's all part of the Node Order of Operations. As an alternate approach, look at the similarity of this technique to Mark Todd Osborne, who is also a very fine colorist here in LA: I do a variation of this with some parallel nodes early on right after normalizing the image with a node for Offset/Printer Lights and a second node for a Custom Curve and/or individual YRGB pots (with Lum Mix at 0), followed by 16 more preset nodes. Most of them are turned off 90% of the time and I only activate them when they're actually used. But then there's days when this happens... (That would be a joke. I do not actually use this many nodes.)
  13. What hardware (CPU, RAM, GPU, disk i/o)? What OS? What kind of source material (codec, bit-depth)? What timeline resolution?
  14. If you're delivering in Rec709, you could also just decode the clip and adjust the Raw files as needed and do it all manually. Store one correction for one type of camera as a Gallery still, and store another correction for the other type of camera as another Gallery still. Then as they go back and forth, grab whatever you need and go for it. As an alternative, you could create a temp grade for (say) the Red files, sort them in C-mode so that all those camera files come up at once, and then apply that temp grade to all of them. And then locate all the BMD files, highlight those, and apply the temp grade there. Go back to A-mode (record) sorting, and fine-tune every clip. It's not that hard.
  15. The International Colorist Academy (icolorist.com) provides training in classroom situations, all the way from basic to fairly advanced. Be advised they're not cheap, but their teachers are top-notch and do a very good job. They provide classes all over the world, so it's possible one will take place in the next few months in your area.
  16. Some good additional reading: VES: Cinematic Color (free 52-page white paper) https://raw.githubusercontent.com/jeremyselan/cinematiccolor/master/ves/Cinematic_Color_VES.pdf Color & Mastering for Digital Cinema by Glenn Kennel https://www.amazon.com/Mastering-Di...=sr_1_1?s=books&ie=UTF8&qid=1514855461&sr=1-1 Digital Cinematography: Fundamentals, Techniques, & Workflows by David Stump https://www.amazon.com/Digital-Cine...855497&sr=1-1&keywords=digital+cinematography Color Reproduction in Electronic Imaging Systems by Michael Tooms https://www.amazon.com/Colour-Reproduction-Electronic-Imaging-Systems/dp/1119021766/ref=sr_1_1?s=books&ie=UTF8&qid=1541130852&sr=1-1 Digital Video and HD: Algorithms and Interfaces by Charles Poynton https://www.amazon.com/Digital-Video-HD-Algorithms-Interfaces/dp/0123919266/ref=sr_1_1?s=books&ie=UTF8&qid=1541131105&sr=1-1 The Art and Technique of Digital Color Correction by Steve Hullfish https://www.amazon.com/Art-Technique-Digital-Color-Correction/dp/024081715X/ref=sr_1_4?s=books&ie=UTF8&qid=1486686304&sr=1-4&keywords=color+correction Modern Post: Workflows and Techniques for Digital Filmmakers by Scott Arundale: https://www.amazon.com/Modern-Post-Workflows-Techniques-Filmmakers/dp/0415747023/ref=pd_sim_14_22?_encoding=UTF8&pd_rd_i=0415747023&pd_rd_r=56C6PQKJHFAEGAHTSYJC&pd_rd_w=5STw4&pd_rd_wg=ZLbLY&psc=1&refRID=56C6PQKJHFAEGAHTSYJC I would also point to the free manuals available from Blackmagic Design for Resolve and from Filmlight on Baselight. Even if you aren't using these particular platforms, there's some great information there on color, workflow, signal processing, and other factors important to colorists. I also think having a good basic grasp of cinematography, lighting, and lenses is crucial, though that's an entirely separate (but related) subject. Being able to anticipate and solve the DP's problems in the color room is very helpful, even when sometimes all you can do is commiserate and try to reduce the problem.
  17. Tiffen abandoned their partnership with DFT and allowed DFT to take it over completely. They're the same filters, just without the Tiffen name on them. And the "Light" patterns are part of it.
  18. The Video/Film tab takes you to a different page, which says: Gobo library for lighting effects includes 751 gobos categorized into Abstract, Doors, Elements, Foliage, Snowflakes, Textures and Windows groups and: The DFT video/film plug-in is licensed on a per host basis. You can choose from: Adobe After Effects/Premiere Pro, Apple Final Cut Pro X/Motion, Avid Editing Systems, OFX hosts or a Multi-Host license which will run all video/film and OFX hosts on the same machine.
  19. New link for the Tiffen "Light" plug-in, which is now run separately from Tiffen by DFT directly: http://www.digitalfilmtools.com/light/
  20. Remember that you can color correct the composited grain, and that will affect the intensity... all the way from almost invisible to very harsh. Just a slight gamma adjustment or a custom curve can do it. I tend to use one of the middle Cinegrain selections when I want to do something subtle. One interesting tip I heard in LA: I know of a colorist who uses 16mm grain on the outside edge of a circular mask, and 35mm grain on the inside. I think that's a little extreme, but if it works for him, I'm not going to tell him he's wrong. You can make an argument for composited grain with a vignette in some cases.
  21. I do so much with windows, masks, filtration, and keys, that LUTs are not part of what I do for the look 99% of the time. On the rare occasions when people bring in a LUT, I'll make a stag at telling them we'll match it "or their money back." As I said elsewhere in another thread, it's possible to completely duplicate a LUT with the controls you already have in Resolve (or any other good color-correction system). A "filmic image" really boils down to great lighting, great art direction, great exposure, and great lenses, and that happens long before the project arrives to the colorist. A lot of it just entails experience, hard work, having an open mind, and being willing to experiment. I stumble over little tricks and techniques all the time, and I've been enmeshed in color and post for almost 40 years now. Try new things, read the manuals, watch the tutorials out there, and find ways to solve the cinematographer's problems.
  22. You can also see Juan Melara's tutorial on how to duplicate certain film-based LUTs as Resolve PowerGrades here: http://juanmelara.com.au/blog/rebuilding-the-600-dollar-linny-lut-for-the-alexa-plus-free-download
  23. Some good reference material here: "Dolby Vision Color Grading Best Practices Guide 2018" http://www.digitalvision.tv/w/images/d/de/Dolby_Vision_Color_Grading_Best_Practices_Guide_2018.pdf I also have collated a few HDR/Rec 2020/Rec 2100 documents relating to post-production which are at this download link: https://spaces.hightail.com/space/nEaXy
  24. On Baselight, no. It's a powerful system, and I'm sure there's an equivalent of it there.
  25. Thanks for this, guys. An introductory course like this is really needed these days.
