Professional AI-Powered Rotoscoping for DaVinci Resolve — Including the Free Version

Transform hours of manual masking into minutes. KVN Rotoscope uses cutting-edge AI models to automatically segment and track moving objects in video, giving you production-quality masks with minimal effort.

⚡ Save Hours of Work

Traditional rotoscoping means drawing masks frame-by-frame. KVN Rotoscope does it for you. Annotate just one frame, and our AI automatically tracks the object through your entire clip - delivering masks in seconds, not hours.

Troubleshooting

Why am I getting an error when I launch the app directly?

KVN Rotoscope must always be started from DaVinci Resolve. Place the playhead over your clip and run Workspace → Scripts → KVN Rotoscope. Launching the app directly without running the script first will result in an error.

Why isn't the KVN Rotoscope script showing under Workspace → Scripts?

Python 3.13 is required. If the script is missing:

1. Download and install Python 3.13 from python.org/downloads.
2. Re-run the KVN Rotoscope installer.

If it's still not showing after that, make sure you're on DaVinci Resolve 20 or later — older versions do not support the Scripts menu location used by KVN Rotoscope.

What do I do if the app has an issue after running the script?

In the KVN Rotoscope window, go to Help → Report a Bug to file a report with your logs attached. This is the fastest way to get support.

What if nothing else works?

1. Fully uninstall KVN Rotoscope
2. Download the latest version from the website
3. Reinstall

Getting Started

1. Download the latest release and install. This will take 5-10 minutes depending on your wifi connection.
2. In Resolve, put playhead over target clip.
3. Go to Workspace → Scripts → KVN Rotoscope. This launches the app automatically
4. In standalone app, session auto-loads on launch; annotate, track, then Render.
5. Back in Resolve, your clip should now be automatically masked!

Known Issues

Intel Mac — slow tracking performance

Intel Macs have no GPU acceleration support. All AI inference runs on CPU, which makes tracking significantly slower compared to Apple Silicon or a Windows machine with an NVIDIA GPU. A 10-second clip that takes ~30 seconds on Apple Silicon may take several minutes on Intel. If you need faster turnaround, an Apple Silicon Mac or a Windows PC with an NVIDIA GPU is recommended.

If you run into any issues, please contact me or raise a GitHub Issue.

Changelog

Version 1.2.9 — Unified script and auto-apply

May 2026

Highlights:

• ✨ Single unified script — Begin.py and Render.py merged into one KVN Rotoscope.py; the script handles the full flow start-to-finish with no separate Render step needed
• ✨ Auto-apply matte — after tracking completes, the matte is applied to Resolve automatically without needing to return to the Scripts menu
• 🔧 Timeline snapshot + auto-revert — a snapshot of your timeline is taken before any changes; if you close the app without finishing, the timeline and compound clip are automatically restored to their pre-Begin state
