Bria Video Eraser (Mask-Based)
Bria Video Eraser (Mask-Based) is a precision video inpainting tool that removes objects using a mask video. Provide the original video plus a matching mask video (white = erase, black = keep), and the model removes the masked regions frame-by-frame while reconstructing the background for clean, production-ready results.
This mode is ideal for creators and post-production teams who need pixel-accurate control over what gets removed—without manual frame-by-frame painting.
Why it stands out
- Mask-based control for precise, frame-consistent object removal.
- Clean inpainting to reconstruct backgrounds after erasing masked regions.
- Works well for VFX cleanup, unwanted object removal, and scene polishing.
- copy_audio toggle to preserve or remove the original audio track.
- Transparent, duration-based pricing with a clear minimum charge and 10-minute cap.
Capabilities
- Mask-video guided object removal (white regions removed, black regions preserved)
- Background reconstruction (video inpainting) across frames
- Frame-by-frame precision for moving objects and tracked masks
- Optional original audio preservation via copy_audio
Parameters
| Parameter | Description |
|---|---|
| video* | Input video file or public URL. |
| mask_video* | Mask video defining erase vs keep (white = remove, black = keep). Must align with the input video. |
| copy_audio | Whether to keep the original audio in the output video (true = preserve, false = remove). |
How to use
-
Upload the video you want to edit (or paste a public URL).
-
Upload a matching mask_video:
- White areas = regions to erase
- Black areas = regions to keep
-
Make sure the mask video matches the input video’s resolution, duration, and timing for best results.
-
Choose copy_audio:
- true to preserve the original audio track
- false to output a silent video
-
Run the model, preview the output, and refine the mask if needed.
Mask tips (best practices)
- Use pure white for removal and pure black for preservation whenever possible.
- Slight edge feathering can reduce hard seams and improve blending.
- If the mask “misses” parts of the object during motion, expand the mask slightly and re-run.
- For complex motion, generate masks with rotoscoping tools or segmentation models, then export as a mask video.

Notes
- The mask video must be properly aligned; misaligned masks can cause jittery edges or incomplete removals.
- Fast motion blur and heavy occlusion may reduce inpainting quality—use tighter masks and short test clips first.
- If you need quick removal without mask prep, use the prompt-based variant instead.
- If you want to generate a mask video. Please use the SAM-3 Video to build one!
