  1. I haven't see this movie yet, but after reading the article I must see it asap. Which system was it used to grade it? I'm particularly interested in the oversaturation/desaturate technique. Was it done with a spliiter/combiner? To make it work the signal needs to be clamped someway? I'd love if someone can answer this!
  2. I haven't had the chance to look into it But as a work around you can use the @Paul Dore aces ofx you can basically build your aces pipeline as a node structure keeping resolve color science in yrgb that way you should not have any problem with video monitor output lut
  3. Hi Michael if the lut is placed in the "3d video monitor output" should not give you any problems as it "should" work post ODT. I might be wrong here tho, maybe its not post odt even if sounds very strange. To make a 3d lut working in aces your best bet would be to use lightspace, @Steve Shaw can really help you out here. Check https://www.lightillusion.com/aces_manual.html under "CONVERTING LUTS INTO ACES" section. Lastly, the monitor calibration does have not to be different if you work in aces or unmanaged, since your monitor will still be a 709 monitor. In aces by choosing the ODT you transform from the aces color space to the choosen one (709 for example) and you have to monitor on the same colorspace you choose with the odt I hope it make sense cheers, Orash
  4. Hi Michael the problem is where you are placing your lut, most likely in aces a "normal" lut cannot be used within the node tree, you either convert it to an aces lut, which is not as simple as it said, Otherwise since it is a monitor calibration lut I would suggest it to load it to the "3d video monitor output" in the color managment tab (that should come after the odt, so should not create problems) or straight into the monitor. hope that helps you Orash
  5. Hi all! I'm planning to buy a mini panel and currently bm is giving (in Italy) a 10% discount. It's not a lot, but still isn't bad. Anyway, are there any rumors of a new panel announced after nab? Cheers Orash
  6. Hi all! It's now a couple of months that I have set up my windows workstation. So far everything it's fine, in still getting used to few things but it's running smooth. I'm finding few bugs here and there and I wanted to check was my problem or it's a common issue. For example : In the deliver page, choosing a render folder, when i right click in the explorer/finder window to create a new folder, DaVinci crashes. Once reopened it doesnt happen no more. Anyone else has this problem? Cheers Orash
  7. Hi! I have just tested my new pc with a gtx 1080Ti and trying to export a red clip 8K with a noise reduce I got two errors: "The GPU failed to perform image processing because of an error" "Error Code: 33." "The GPU failed to perform image processing because of an error" "Error Code: 77." I'm using Resolve If I disable in the preferences "use GPU for RED debayer" I don't get the errors but of course it slows down quite a lot Did anyone found a solution for it? cheers, Orash
  8. Also, if you don't check Luma and sat mapping but you trim by hand, there is not clipping after the transform
  9. Your comment on "the hobbit" thread helped me find the article I was referring to 😊 In that article it clearly state that printer point are used to control highlight and shadows. I was wandering what it meant and how was that achieved.
  10. Agree! Altought I was hoping to get a little deeper insight, but I hope some more things can come up in the comments. For example I was reading in some other article (can't find it right now, I will look for it) the use of printer lights also to control with precision different tonal range like shadows, mids, hilights. How that can be achieve? By keying the 3 tonal ranges and keep them in parallel, perhaps? It's quite long time im using printer points for my base grade, and I have to say it's the best tool as far I'm concern
  11. I'm not really a "happy new year" guy but I wanted to take this chache to thank the people behind this forum and the users involved. I have to say lowepost has become a great resource of information and I'm thankful of the help, tips and tricks and info I found here. So I wish to this forum and the users a great new year, full of nice info, tutorial and insights.
  12. With this estimate time is taken into consideration the "needs" of dop and director or are this "maximum" timing given by budget/production I work with a dop (that I really like and we have great relationship) that is not easy to work with, he just doesn't want to stop. He could work on a grade for a whole year if someone doesn't stop him, and I cannot always do that.
  13. Love this format and Kevin is really clear on explaining every bits and pieces. Thanks a lot for the efforts
  14. The way I do it is to key the highlight, add a ton of blur to the key, then lift both gamma and lift while lowering the gain to control. If needed add a bit of colour to the lift control.
  15. Hi @Jeremy Dulac! here's a quick example of how you can use the edge detect node Let me know if this it helps Orash
