For Natron alternatives, port a short shot with masks, tracking, keying, color correction, and an image sequence.
- Compare node behavior and output frame by frame.
- Test color management, bit depth, plugins, and render-farm or batch use.
- Relink assets after moving the project to another workstation.
- Measure render time and stability under production resolution.
- Preserve source project and intermediate assets until revisions are possible.
A matching final clip is not enough if the node graph cannot be maintained. Check the editable project as carefully as the render.
