    I think that you should have mentioned the scopes in Resolve - I have mine always set to 10-bit - data levels and all imported files display with the black and white levels at 0 and 1023 -.
    Just mentioning because people may get confused while looking at the scopes.
    We usually tell people that the "auto" for levels where it seems to get the right call almost all the time. It's kind of a "set it and forget it" option that most "auto" is not.

    Very important topic, and I haven't really seen a lot of people talk about it. Especially at this level! Wonderful video, Marieta. I agree on using "Auto" for most codecs. But I noticed that when working with any DNx codec and using Premiere or Media Encoder afterwards, you wanna make sure to tag it correctly, because Adobe will for sure misinterpret the "Auto"-tag.

      Thank you, Sven! That's a very good point. I find that DNxHD 444 specifically forces full data levels causing a gamma shift in Premiere Pro. But since my last tests Adobe have introduced Colour Management so they may have fixed it. Or, at least, they hopefully now offer the ability to switch between Full and Video levels the way Resolve does.

    I just got a BenQ monitor (I think you have the similar one), and I've been struggling with calibration because I constantly have crushed blacks. Then you release this video, which I think has put me on the right track. Now I’m optimistic again that I’ll be able to set up the monitor properly. Thank you!

    • @marietafarfarova
      @marietafarfarova  29 дней назад

      That's a great question! If you're creating colour-critical work as a professional in Resolve, it is essential that you have a dedicated calibrated colour grading monitor and you're feeding a clean feed to it via a capture and playback card. Otherwise, what you see in your viewer is affected by your OS and it's not a reliable representation of your grade. It doesn't matter where your deliverables are going.

    Merci pour cette vidéo. Peite question, si nous faisons le choix de partir sur un projet avec de l'ACES, je ne vois plus la possibilité d'appliquer le choix d'option REC709-A, ça me stresse un peu car j'ai peur de retomber à nouveau dans les différences de rendu entre l'export et le viewer. Comment avec l'ACES, quand on est sur Mac, pouvons-nous être sûr qu'il n'y aura pas de différence entre l'étalonnage avec le viewer et les exports ?

    • @marietafarfarova
      @marietafarfarova  28 дней назад

      I'm really sorry but as mentioned in the video, this is not referring to the Mac gamma shift and the Rec709-A workaround. I don't use Mac so I cannot test, troubleshoot and provide any clarity on this subject, unfortunately. To my knowledge, there is a great video by CineD about this topic you may want to go through: ruclips.net/video/ZQ8VY9aWUfE/видео.html&ab_channel=CineD If this doesn't answer your question, it may be worth asking @DouglasDutton to create a video on this topic as I know he is on a Mac and has experience working in ACES.

    Hi. Thank you for your explanation. I'm running into problems that I thought were connected to this, but after trials doesn't seem to change the fact. When working with HDR in resolve, the exports played back in QuickTime do not match. Both mediapool clips and exports are set to auto, but the exports in QuickTime get desaturated, and brights and lows are gone and thee video is overall less contrasty, almost like if it was SDR. The outputs are in rec 2020 st2084

    • @marietafarfarova
      @marietafarfarova  29 дней назад +1

      Hey. I have a number of questions about your setup:
      1. Are you grading on a reference monitor calibrated for HDR and set to Full/Data levels?
      2. Are you sending out Full/Data levels from DaVinci Resolve (under Video Monitoring settings)?
      3. What is your OS?
      4. Is your second monitor, where you're viewing the deliverable in Quicktime, set to Full/Data levels?
      But to be honest, I'm unsure whether it matters at all how your deliverable is shown on a Quicktime player. The only thing that matters is how your grade looks like on an HDR calibrated mastering display. And I mean a proper one e.g. Sony BVM-HX310 or FSI XMP310, not a consumer-level TV such as LG C3 that claims to be HDR.

      ​@@marietafarfarova Hi. Thank you for replying.
      No I'm actually on the XDR 1600 nits Mac display. I know that you are recommended a secondary display for editing, but this is a great display, and still shouldn't give this result?
      I have been trying both changing clips in the media pool to full/data and following the same steps in the deliver page but none of that is giving a difference in the exported file.
      Sonoma 14.5.
      But what it sounds like from you, and from the guys I was speaking over at blackmagic etc, is that you can't trust the Mac display, no matter which one it is. And that problem wouldn't exist on a proper secondary display.

    • @marietafarfarova
      @marietafarfarova  28 дней назад +1

      ​@@SkardeLine Hey. The issue with not having a dedicated colour grading reference monitor that is connected to a playback and capture card, is that otherwise what you're seeing in your viewer is being affected by your operating system and is not a true representation of your grade from Resolve. Therefore, it cannot be trusted. You can have the greatest display. But if it's not connected as a dedicated calibrated ref monitor receiving a clean feed - it doesn't matter how amazing that screen is.
      I hope this helps.

    I don't understand this tube. For a long time I used data level full video renders because these settings are compatible with my RUclips and social works, and I don't see any issues, I don't see the crushed colors or blacks that people mention or speak about. Used mostly Prores 422HQ or DNxHR444 12bits. Every time I tried Auto or Video settings because I read or see somewhere that's the pro way to do it, it is doing exactly the opposite of what I need, losen contrast and less punchy colors, And I am not using any of these devices for monitoring. Note that I am not trying to diss down this video, on the contrary, I want to understand the issue to either improve my workflow or knowing how to adress it properly if I come accross the problem.

    you forgot to mention one problem that colorists often face. Davinci on wind generates DNX files in RGB space with video levels. Premiere thinks that all DNX files are in XYZ space with full levels. Because of this, after rendering from Premiere, the picture fades.

    • @marietafarfarova
      @marietafarfarova  29 дней назад

      Thank you for your insight. In this video I wanted to focus on the broad picture rather than specific issues related to codecs and incorrect decoding by different software.
      In my experience, I've only faced issues with DNxHR 444 12-bit - Premiere interprets the file as full data levels even though it should be video. But I have not had any issues with DNxHR HQ.

    This isn’t a gamma shift, it’s contrast, you should make that distinction

      @marietafarfarova  28 дней назад +1

      @@m1nt9reen You’re absolutely right. However, if someone is looking to troubleshoot an issue related to data levels, it’s quite likely the term they would use is ‘gamma shift’ even though that’s not the correct technical term. So while I agree with your point, I’d much rather use a term that people are searching for so they can find this.

      In this walkthrough, it’s shown how to connect to FTP. However, the steps are identical to connect to Google Drive. All you need to do once you’ve downloaded Cyberduck is to Open Connection -> from the dropdown menu select Google Drive. And this is going to open up a new window in your browser prompting you to log into your Google account. Once you’re in, just allow Cyberduck to access your Google Drive account and you’ll then be able to upload and download anything via Cyberduck. This avoids Google Drive’s zipping and the speeds are significantly faster. Hope this helps.
