Shape the cleanup area yourself
Mark the exact area that needs attention.
Start from a detection suggestion or create the selection yourself with rectangle, polygon, brush, and eraser tools.
Workflow
A workspace built around the frame, not a form.
Draw directly on the video, tune the edge, inspect the timeline, and save only when the selection looks right.
- 01
Choose a tool
Use Rectangle for fixed marks, Polygon for hard edges, or Brush for irregular areas.
- 02
Draw on the frame
Place the selection around the visible overlay and use zoom or pan for detail.
- 03
Correct the shape
Add with Brush, remove with Eraser, or use undo and redo.
- 04
Tune the edge
Expand or shrink the region and feather its boundary to reduce seams.
- 05
Review nearby frames
Check the selection on bright, dark, and visually busy moments.
- 06
Save and preview
Generate a short result before the full processing job.
Capabilities in context
The right tool for the shape in front of you.
Capability 01
Rectangle
Fast selection for corner logos, timestamps, and other fixed regions.
Capability 02
Polygon
Point-by-point control around sharp or angled graphics.
Capability 03
Brush and Eraser
Paint irregular areas, then remove any part that extends too far.
Capability 04
Mask properties
Adjust expansion, feathering, brush controls, and temporal smoothing.
Practical review states
Know what to look for next.
Each state points to a concrete next action instead of leaving you with a vague score or success message.
Corner logo
Use a small rectangular mask with a slight expansion beyond the visible edge.
Timestamp
Check several timestamps so changing digits remain inside the selection.
Subtitle line
Use a wide, shallow region and verify it does not cover scene text you want to keep.
Irregular graphic
Combine Polygon and Brush for shapes that do not fit a clean rectangle.
Keep the limitation visible before the job starts.
- The current MVP applies the saved mask across the full video; custom time ranges are not yet a separate processing mode.
- Extend the mask slightly beyond visible edges, but avoid covering nearby details.
- Feathering can reduce seams, but it cannot repair a poorly positioned mask.
- Reset and redraw are always available before processing begins.
Next step
Precise control when the footage needs it.
Start with authorized footage, review every selected region, and use a preview before full processing.
