Background Remover

Background Remover is available exclusively on Beeble (Cloud app). It is not available in Beeble Studio.

Background Remover extracts clean alpha mattes from your footage using AI, producing background-free results ready for compositing and VFX work. Upload an image, video, or image sequence, and the AI generates a precise foreground mask automatically.

Background Remover is a standalone alpha extraction tool. For generating a full set of VFX passes (alpha, depth, normal, PBR maps), see Generate VFX Passes.

Key Features

AI-Powered Alpha Extraction

Extract clean alpha mattes using advanced AI models for professional-quality results.

Keyframe Preview & Refinement

Two-phase video processing: preview rough alpha keyframes first, refine interactively, then run full extraction.

How It Works

Step 1: Upload Your Footage

Upload your footage to begin. Background Remover supports three source types:

Single Image — PNG, JPG
Video — MP4, MOV
Image Sequence — Sequence of image frames

Step 2: Keyframe Preview (Optional)

Keyframes are first extracted with rough alpha previews generated on those frames, so you can review the overall quality before committing to full extraction.

The keyframe preview shows a rough alpha estimation — it is not intended to be pixel-perfect. Fine details like hair edges and semi-transparent areas will be refined during the full extraction in the next step.

If the keyframe alpha needs adjustment, you can refine it interactively by clicking the Edit Alpha button in the Keyframe Dialog.

Skip Review mode — You can choose to Skip Review during upload, which bypasses the keyframe preview step (Steps 2–3) and runs full extraction immediately.

The AI automatically uses the first frame as the keyframe and runs the entire pipeline without manual review.
This mode works best for simple shots with clear subjects and consistent backgrounds, where manual refinement is unlikely to be needed.

Step 4: Full Extraction

Once you approve the keyframe previews (or skip them), full extraction runs across all frames.

Step 5: Download Results

When extraction completes, download your results. You can also bulk download multiple completed results at once.

	Beeble (Cloud app)
File Format	PNG, JPG, JPEG
Max Size	100 MB per file
Resolution	Up to 2K (2048 px) - Rejected if larger
Max Frames	Up to 2000 frames
Color	sRGB for best quality - Other color spaces, such as Log, may degrade quality

FPS	Up to 30 FPS - Reduced if higher
Color	Rec. 709 for best quality - Other color spaces, such as Log, may degrade quality

Best Quality Settings - Use Rec. 709 / sRGB color space. Beeble (Cloud app) supports up to 2K and 60 seconds.

Output Format

Beeble Cloud provides two output formats:

PNG: 8-bit PNG sequences for each output.
MP4: 8-bit MP4 files for each output.

Output	Color Channels	Bit Depth	Color Space	Note
Source	RGB (3-ch)	8-bit	sRGB
Alpha	Grayscale (1-ch)	8-bit	—	0.0–1.0 matte
Processed	RGBA (4-ch)	8-bit	sRGB	RGB with transparency applied

Output	Color Channels	Bit Depth	Color Space	Note
Source	RGB (3-ch)	8-bit	sRGB
Alpha	Grayscale (1-ch)	8-bit	—	0.0–1.0 matte

MP4 (H.264) does not support alpha channels, so a Processed (RGBA) MP4 is not available. Use PNG output to get the RGBA composite as a PNG sequence.

Tips for Best Results

For the best alpha extraction results:

Use footage with clear contrast between subject and background
Ensure the subject is well-lit and in sharp focus
Avoid footage with excessive motion blur
Use high-resolution source material when possible
For videos, review and refine keyframes before running full extraction
