Advanced Depth of Field in Davinci Resolve - Fusion

[@CameraTim]

The more I learn about different mapping and matte tools, the more I love Fusion. Love these types of tutorials!

[@alwayscallingmeblaze]

Just wanted to say I love your stuff. I have been following you since near the beginning. I know this niche of KZbin isn't very rewarding, but I greatly appreciate you taking the time to provide these videos. You put in the VERY hard work to get to know Resolve inside and out, and you're one of the very few I view as a real authority on the subject. Thank you for keeping up with it!

[@VFXstudy]

Thanks a lot for the support!

[@CodyHovland]

Clean Plate is a game changer! thanks for showing me this!

[@VFXstudy]

It is - though for depth map more like a hack from the keying world :)

[@richarddurkin833]

Amazing Bernd, I can't thank you enough for this.

[@millolab]

There’s the DepthBlur node in Fusion. It’s not as good as Frischluft but it’s there!

[@VFXstudy]

But it doesn't work like a Depth Blur. It produces the same result as a Blur with a depth channel attached as a mask. So it's not really doing what we need it to do.

[@millolab]

@@VFXstudywhat are you referring to?

[@VFXstudy]

@@millolabThe standard DepthBlur (DBI) tool. I believe it just uses a fixed Blur size and then blends the blur based on the depth map, like if you shuffled the depth map into an alpha channel and used it to mask a regular blur node. From what I figured, it doesn't change the blur radius based on the depth and it doesn't operate in a layered way, where background pixel are blurred without the impact of (less blurry) foreground pixels.

[@millolab]

@@VFXstudy it’s not the best, but it doesn’t use the depth map as a mask.

[@VFXstudy]

@@millolab Oh, now I think you are right. I just did another test. Indeeed it seems to be better than I remembered. It seems to be quite similar to the VariBlur - although not precisely. So it does seem to vary the blur radius but doesn't seem to do any layering or so to deal with edges.

[@thielecomposer]

Thanks a lot for your awesome tutorial, yet again! If only it had come out a week earlier - I could have used that info on a video I just sent to a client :D Keep it up!

[@hisroyalillness]

great overview!

[@totox691]

Very clear and informative tutorial as usual :)

[@arnoldsnodgrass2953]

Very useful indeed and very clear. Thanks

[@erikals]

Great review! Thank You! ⭐

[@VFXstudy]

Glad it was helpful!

[@mazefaer]

Goat back!

[@muscle__rr]

Wow, really really helpful

[@ProjectHelisexuality]

Fusioneer!

[@tyesamson]

Really appreciate this, thank you! Have you played with the color page Tilt-Shift effect? It uses a lens blur and comes with the option of plugging in an external depth matte so you don't have to use the janky tilt-shift emulation controls. I'm pretty sure that the effect is available on the Fusion page but I'm not in the darkroom this second to confirm that it can take the external depth matte in Fusion the way it can on Color page. I lean on it a lot in order to avoid the ugly opacity fall off you point out here. Would love to see an A/B with the 3rd party OFX you demo'd!

[@VFXstudy]

Good point. I'll have to try. I think it's probably similar to the variblur but haven't done the comparison either and am flying now. Maybe someone can test/comment?

[@ApexArtistX]

can you do a z depth generated by depth node to use as compositing alpha of background CG elements

[@VFXstudy]

you can put a z-depth into an alpha chennel with a channel booleans or copyAux node. But it's also possilbe to direclty use the z-depth inside a merge node.

[@thatcherfreeman]

I find you can substantially improve the quality of blurring in post by blurring an image that's been converted to scene linear. Even gaussian blur looks pretty good when in linear, whereas it looks horrible on log images.

[@VFXstudy]

Sorry didn't mention that, but I did work in linear for the cg render.

[@smepable]

​​@@VFXstudyis it possible to affect the Iris/aperture shape or other technique to get an anamorphic Blur? Like in this Video at 10:35 but I dont understand how he gets that shape kzbin.info/www/bejne/aqrSomSohbl_e9Usi=os_z2JRnk7bXLM6p

Hello, I am trying to make a fusion template for the folder "Title" and I did everything you said in a previous video about macros and how to do it, when I share the macro to my other computer it does not work at all I have multiple pictures in there so I am not sure if that is what is wrong but my macro is not working on another computer

[@VFXstudy]

If you have pictures or videos in the macro, you should load them via a Fusion loader node within the macro. Inside that you can use the Setting path to create a relative path and then make sure you have the assets in the same folder or relative path as you point in the loader. Not sure about the exact path syntax, but you can check it if you open the macro in a text editor. There should be a setting (or settings??) variable that you can use.

thanks

Hi, I’m trying to do something that may not be possible for DaVinci Resolve. I’m trying to create an effect that looks like pouring black ink into water. I don’t care about the water or the pouring. But, I’d like to see the movement of the black fluid as it spreads out. I tried using … well, many things but I cannot seem to get close. I think Blender would work but I do not know how to use it yet. Any ideas? Thanks!!

[@rano12321]

You'd have to create fluid simulation for that so you'd have to use a 3D software.

[@VFXstudy]

Indeed. In theory some very rudimentary fluid simulation could be approximated with Fusion particles, but in practice you probably want something more powerful. Blender could be a good start.
