      @@VFXstudy Hi Brend, great tutorial as always, love all of your work!! I had a quick question, I have a video clip of a tree which has a transparent background (appears black in Fusion or Resolve) and there is a duplicate video clip showing only the white alpha of the tree. What would be the best way to use these two clips together to have a clean clip of the tree which then has a transparent background? The only way I managed to do this is with the Luma Keyer, but I was wondering if I could use the two clips together somehow so the black background appears transparent as soon as I import the clips into Fusion or Resolve. Not sure I’m making sense but any advice would be great! Thanks

    Hello Bernd, very good presentation. Seems like you are the specialist who can answer me a question in regards to compositing :) In my green screen recording environment I would like to set up more than one physical static cameras. The plan is than to integrate the different camera views into a virtual studio scene. In order to do this correctly, I would like to somehow use Davinci to compute the camera poses (3D position + 3D orientation) in the room. I thought about setting up the cameras in front of a calibration pattern before the actual recording, to get both cameras into the same reference coordinate system. I have seen that Davinci supports Camera tracking for a single moving scene. Maybe this could be used somehow? Maybe stacking a reference shot from the calibration pattern of each camera into sequence and that using the tracker to get the relative pose between camera positions? Of course things could be made a lot better if Davinci already has camera calibration algorithms on board which would allow to preset camera characteristics like focus and pixel size. Thanks for your response and your great channel. Helps a lot to get started with Davinci! Best regards, Christoph

    Very good video. It will be interesting to see an example of workflow where the greenscreen is digitally added with software for example with runawayml.

    • @VFXstudy
      @VFXstudy  Před 2 lety

      You can also try the magic mask in the DaVinci resolve Color page to get an AI / Machine Learning extraction of a person. Not sure how it compares with runawayml. Some software extracts the subject and then places it in front of an artificial greenscreen - that's generally not a good solution, it's better to output the extracted object with an alpha mask in a file format that supports alpha channel (like ProRes 44444 or DNxHR4444). But if you do get a digitally added green background, then extracting that is usually quite simple and tends to work with pretty much any keyer you want.

    I'm learning keying in Fusion, but I'm encountering an issue with the delta key transmission to matte control. Why does the key quality degrade in this process? Conected to the matte control mode a green edge is showing up again?

    • @VFXstudy
      @VFXstudy  Před 5 měsíci

      Not sure how you connect it or how you use the MatteControl. Generally, if you use the RGBA output, there's no way MatteControl could add a green edge that the DeltaKeyer already removed. However, perhaps you are using only the alpha channel from the DeltaKeyer? In that case any despill that the DeltaKeyer might perform would be ignored. Sometimes that's exactly what we want if we do despill separately or want to try different algorithms for Despill.

    • @VFXstudy
      @VFXstudy  Před rokem +2

      That's quite tricky. Because of blur you probably get a very soft mask in the wavy area which let's a lot of green through. After doing despill it'll get dark or grey in that area - there is a technique called adaptive despill (covered in my compositing course), where you compare how much spill you removed in the semitransparent area and then replace it with the appropriate amount of background image (or a blurred background) to a better appearance of the semi-transparent areas. Another attempt would be to tighten the mask so it's quite hard and then add artificial motion blur again afterwards.

    after doing such a complicated node tree for the keying, my fusion renders the image sequences at abysmal speeds using the saver node, sometimes up to 6 seconds per frame. I also realised that fusion is using much of my GPU to render the frames, do you have any advise to optimize the Fusion render speeds? I'm already using at RTX3080.

  • @austinbaker5840
    @austinbaker5840 Před 2 lety

    Hello, I followed these steps, but when I go to the status tab on the delta keyer, the fine hairs and edges have a layer of gray around them and there appears to be some kind of flashing effect around the flyaway hairs when I playback the video. Is there a way to remedy this? Is this covered in your course on the vfxstudy website? I was thinking of purchasing.

    • @VFXstudy
      @VFXstudy  Před 2 lety +1

      It's always tough to cover a specific issue on a specific shot. The gray probably comes from the spill replacement. Maybe you eroded or blurred the edges a bit or have the mask a bit two wide. See how the alpha is there. In some cases you can tune the edges within the deltakeyer and possibly change the color replace mode. The course goes into some more detail of the individual steps including some edge refinement, edge extension, and adaptive despill. Of course there will still be tuning on any individual shot.

    Hello and thank you for the very detailed tutorial! I have 10 years of experience in After Effects and I do mainly keying and compositing. Recently I'm considering learning Fusion and switching to Davinci Resolve, but after I watched this video I'm not so sure. The greenscreen shot you showed here is not a complicated case at all. In AE, I would just create a rough hard key with "keylight" and then I would add "key cleaner" effect, which automatically refines the mask details. And that is in most cases all you need for a really good key. I understand the process you are doing here but it seems so demanding and complicated! Isn't there a simpler way? Something like the simple process in AE that I use?

    • @VFXstudy
      @VFXstudy  Před 2 lety +1

      Sure, you can simplify it. The purpose of the tutorial was to show an advanced workflow for maximum artisitc control for demanding shots. At the end you only do the steps needed in any specific case.
      Keylight in AE is pretty much the same as Delta Keyer in Fusion. I'm not sure what that "key cleaner" effect does, but there are refinements inbuilt into the delta keyer, an inbuilt clean plate tool and you can do a simple hard comp soft-comp approach by concatenation two delta-keyers. See my earlier delta keyer tutorial for that. Often that will be enough. But for tough problems or holywood-grade results you might need more...
      I think it's less about the software but more about how much control you want and need. Vice versa, the workflow I am showing here can certainly be done in AE as well, though you would need some pre-comps and it might get even more cumbersome with that.

    • @JaroAtry
      @JaroAtry Před 2 lety

      @@VFXstudy Thank you for your answer! The "key" feature in AE for me in the Key Cleaner. You can feed it with a very rough mask and it calculates the perfect soft detailed mask based on the local contrast around the edges. This makes the keying process co much easier. You dont have to deal with any problems with uneven background or green spill in the subject making your subject transluscent because you can set your key threshold as high as you want. The only goal is to separate the subject, doesn't matter if the mask is ugly and you lose the hair details and stuff because when you apply the Key Cleaner, it will bring the mask details back. Can you do this in fusion somehow?

    • @VFXstudy
      @VFXstudy  Před 2 lety

      @@JaroAtry is this an AI powered algorithm? I don't use AE so I don't exactly know what that is. Thoug I suspect that it's just something like a hard comp fill which you can do with an additional key or matte control. Again hard to say exactly what it is without side by side comparison.
      purely technically speaking there can't really be a process like that that always works. Spill and transparency are different things from different sources and desired transparency and accidental transparency look the same on a pixel basis.
      So either AE just simplifies a more generic process which works in many cases - like my other tutorial, that's whatI suspect, or it's an AI powered tuning trained for the most common cases (don't think so but possible).
      Probably AE also uses a clean plate internally. Delta keyer can do so via the second tab.

      So short answer yes. The tool is called Delta Keyer, the process @VFXstudy is describing in the video above is a maximum artistic control workflow. Why don't you try the Delta Keyer tool and see how it compares to the AE effect tool? Its a 10 second process. Add the node, use the color picker to choose the chroma key color, release your finger, and boom its done. Then use your threshold to manage and refine the mask.
