Blackmagic Forum

Hi there,

my first post here.

I'm trying Fusion and I'm liking it a lot so far.
One of the thing I couldn't find though is a good zdefocus tool. Is there anything to add realistic defocus using zdepth passes?

a quote from different thread on this forum:

michael vorberg wrote:there is no native depth based defocus in fusion right now. if you have a studio version which can load plugins the best solution is the frischluft plugin. which is really nice.
for the free version you could try a macro: http://web.archive.org/web/20110823131222/http://vfxpedia.com/index.php?title=Settings_and_Macros/DepthDefocus_Description

Thank you for your reply Marek,

Sorry if this was already posted, next time I'll try to search better

I'm trying to decide what to pick, if Fusion or Nuke. At work I can already play around with Nuke, and with Fusion free I can test Fusion as well.
3d wise I prefer Fusion, way better. Also, not sure if it's because I've already started with Nuke, but Fusion seems very intuitive.

I really hope they'll add a native Zdefocus in the next version.

Best,
Carl

no problemo, Carl
glad to be of a help.

happy fusioning and Merry Christmas, Everyone!

Someone pointed me to a macro on this forum that does a pretty good depth defocus. But the built in Variblur node also does a pretty good Z-defocus (but without shaped aperture) you just need to use a use a 'bitmap' node to convert your depth image to a 'mask' & set the blur type to 'defocus'

heres a little flow to demonstrate:

Depth blur is working fine for me so far, the only issue is that you don´t have some nice features like bloom and aperture shape.

I hope that helps.

Cheers!

actually blooming should be there., but as looked for it i couldn't find it... ?
will look further into it
aperture.. not so much - but You have sth called - Bokeh Profiling- play with that (if You haven't already)

I think the most impressive part of the example is the grid made with paint node!

haha thanks, I'm an artist at heart...

Sorry to state the obvious,
but there is a GridMaker Macro in Bins->Templates->Layouts...

Cheers.

Eric.

heh, maybe obvious to you, I hadn't even found the bin!

Hi Marek,

For blooming, please make sure that the Pre-Gamma / Post-Gamma checkbox is switched on and adjust the Image Gamma parameter.

It sits there for the case, when your input image is in sRGB or another non-linear color space. But even if you work in a totally correct linear way, you can still use that pair of controls to exaggerate the bokeh for artistic purposes.

i have DepthDefocus made by Chalenko from fusion instruments, but i have no right to give it to anyone, so if you can find it somewhere its yours... this defocus have bloom, normal borders, fast enough, and native and other good things that i can not describe because of luck of englesh language.

Wow! i didnt so chalenko post up here
