Thank you for downloading Tracer Free by Visual Library.
Your support means a lot and helps us keep creating tools for the community.

═══════════════════════════════════════
INSTALLATION
═══════════════════════════════════════

1. Unzip the whole package first. installer.lua and the content folder
   must stay together in the same location.
2. Open DaVinci Resolve and navigate to the Fusion page.
3. Drag and drop installer.lua directly into the Fusion node area.
4. Follow the on-screen prompts and click OK to agree to the licence and
   complete the installation.
5. Restart DaVinci Resolve.

Tracer Free is a Fuse, so it is used on the Fusion page:

  Add Tool  ->  Fuses > Tracking > Tracer Free

You can also press Shift+Space and search for "Tracer Free".

Prefer to install by hand? Copy TracerFree.fuse from the content folder
into:

  Windows : %APPDATA%\Blackmagic Design\DaVinci Resolve\Support\Fusion\Fuses\
  Mac     : ~/Library/Application Support/Blackmagic Design/DaVinci Resolve/Fusion/Fuses/
  Linux   : ~/.local/share/DaVinciResolve/Fusion/Fuses/

...then restart Resolve.

USING IT
═══════════════════════════════════════

Add the Tracer Free node to your comp and feed it an image. It finds the
bright areas of the frame (or the dark ones, with Invert Detection) and
draws markers, boxes and traces between them on top of your footage.

  Threshold     - how bright something has to be to count as a target.
  Target Size   - ignore targets smaller / larger than this.
  Grid Size     - the pixel stride used for detection. Lower values are
                  more accurate but slower.

Tick "Preview Detection Mask" to see exactly what is being detected.

═══════════════════════════════════════
