Creative teams waste time describing visual ideas when they could be sketching directly on reference footage.
Create a web-based tool that lets teams load video, scrub frame-by-frame, and draw annotations that persist across frames. Add simple version control for iterations.
Target small animation studios and video production houses with team plans. Charge per project or monthly.
Start with a basic single-user sketching tool, then add collaboration features.
Risk: Existing video editors may add similar features as plugins.
