ITO Production v1 native Fusion presets
These restrained presets are separate from the preserved ITO_V28 compatibility examples. The parent review approved their two-source still previews. Exact installed imports, parameter/connection readbacks, save/reopen and six 30-frame renders passed verification. The Lua installer also passed actual installation and an idempotent rerun, with original presets unchanged. They do not change the finished V28 film.
Presets
| Preset | Behavior | Starting strength |
|---|---|---|
| HighlightBloom | Glow limited to brighter image content, without an exposure or color-gain node | Threshold 0.70, glow gain 0.12, 6px glow size, 22% blend |
| RGBFringe | Opposing red/blue spatial offsets with unchanged original green/alpha routing and duplicated edge pixels | Normalized horizontal offsets −0.001/+0.001, approximately −1.92/+1.92 px at 1920 px width |
| LumaHalo | Thin glow through a Sobel/luminance mask recomputed from each source frame, without translating the image | 2 px glow size, glow gain 0.10, 25% blend |
The halo follows image edges through its per-frame mask. It performs no object detection or tracking. These are conservative starting values, not a universal match for every shot or reference. RGB output is recombined from actual spatially offset channels; it does not remap green from alpha as the compatibility example does. Both glow nodes use frame clipping. Alpha preservation is established by node routing/disabled alpha processing; H264 proof renders do not contain alpha.
Install
Keep the three .setting files beside install_ito_production_v1.lua. On macOS run the saved installer from its absolute path:
"/Applications/DaVinci Resolve/DaVinci Resolve.app/Contents/Libraries/Fusion/fuscript" -l lua "/absolute/path/to/reusable/install_ito_production_v1.lua"
It installs into your user Fusion/Macros/ITO_Production_v1 directory. It preflights every source, refuses conflicting installed bytes and verifies readback. Identical reruns are allowed. Existing ITO_V22 and ITO_V28 files remain untouched.
Import and connect
Use Resolve's TimelineItem.ImportFusionComp with the actual installed .setting path in a new composition or duplicated clip. These are serialized tool-graph snippets, so add the clip's MediaIn and MediaOut boundaries. Internal links are already serialized.
- HighlightBloom: connect MediaIn to ITO_PROD_Bloom.Input; connect Bloom output to MediaOut.
- RGBFringe: connect MediaIn to RedOffset.Input, BlueOffset.Input and RedCopy.Background. Connect BlueCopy output to MediaOut. Each node name carries the ITO_PROD_ prefix.
- LumaHalo: connect MediaIn to Contours.Input and Halo.Input. Connect Halo output to MediaOut. Each node name carries the ITO_PROD_ prefix.
provenance.json records exact shipped hashes and a sanitized summary of prior native verification, with hashes of the separately retained evidence. The earlier ITO V28 compatibility examples are not recommended production defaults. This package does not include the source footage, native project or proof renders.
