Fusion Notes

This notes relate to Resolve inbuilt fusion tab, Davinci Resolve Studio 16.2.3.015.

Shorcuts ↓

Ctrl + p is pass-through for a node.
Ctrl + t is switch bg and fg
Ctrl + shift + lmb drag pans the node tree
V toggles node minimap
shift + space opens search for nodes
Ctrl + G group, Ctrl + E toggle collapse

Preview ↓

Rmb on node and select ‘Create/play preview on’. Shift+Rmb will reuse settings and skip quality selection tab.
Note: Seems to be flaky, easier way is to exit back to resolve timeline and see it rendered there.

What exactly is proxy/autoproxy thing?

Various ↓

There is save image in viewers and it will save png with alpha.

Routers are tiny nodes used to reshape the look of the node-tree. To add one, alt + click anywhere on the connection

To extract/disconnect node or nodes from a tree shift-drag them.

Node format is not binary, one can copy paste them into text editor and back.

Nodes can be instanced, ctrl+c a node, rmb on background and select ‘paste instance’. A green line shows the link. Instance can be deinstanced. More interestingly a single parameter on that instance can be deinstanced (rmb on parameter name in inspector and choose deinstance).

Organization can be performed by using underlay boxes or groups. Groups can be precached on disk (in theory, in reality this seems to freeze fusion in resolve…, maybe in standalone version?). Groups can be saved to disk (rmb/settings/save as - page 172) and reused by drag droping.

Macros are an advanced version of groups, one that enables creator to select exposed user inputs… Shall be used to generate for example title templates for resolve editor. Titles should be stored in C:\Program Files\Blackmagic Design\DaVinci Resolve\Fusion\Templates\Edit\Titles.

Layers ↓

This are 4k layers (png) and I seem to run out of gpu mem after adding a few more of this lines…

This is multilayer psd (scaled down to 1920x1920), with instaces of this one single input and deinstancing layer and selecting each layer in inspector we can recreate this layer uhmm stuff. Seems like a lot of manual work.

edit: There is also import psd which generates some sort of node structure automagically. edit2: Also import svg, but slow and crashy (Don’t use).

An attempt to add some sort of preturb/shake animation to some/most of this layers, precache will take 35 minutes on this machine, seems really really slow (and this is pure 2d comp). ‘Cache to disk’ didn’t really work, manual render from resolve timeline now.

2nd pass, fx and some compositing

Experiment 1. ↓

Merge node has in 3rd tab of inspector an option to select what is used as mask/key channel (should only show when mask is connected).

Higly profesional final comp (with a lot of confusion what matte really is at what point …)

The one with TV effect

Animation

Text on path, char by char ↓

a. In text inspector, 2nd tab select type/path
b. rmb on ‘Type’, select ‘bezier spline’
c. use tools in view to add/move points, you can smooth with rmb on points and select ‘Text1:path/smooth’.
d. animate position on path…

textOnPath animation

Defocus ↓

Expressions ↓

There is no int. Looks like LUA.

This is working

math.ceil(calculatedangle.Angle)
math.floor(calculatedangle.Angle)

Construct text (for styled text input)

Text(input_.Width.."."..input_.Height)
# returns 1.12

Padding

Text((math.floor(input.Width)).."."..(string.format("%02d", math.floor(input.Height))))

if then else (1st if true, 2nd if not)

iif(math.floor(calculatedangle.Angle) < 361, math.floor(calculatedangle.Angle), math.floor(calculatedangle.Angle)-360)
