Detailed Comparison

1. Background Removal Quality

CapCut: Uses ByteDance's AI (same company as TikTok). Automatic detection works well for people in simple scenes. You can manually refine edges with the eraser tool, but it's frame-by-frame manual work.

OBS Mask Generator: Uses Meta's SAM 2.1 AI. You click on the subject once, and the AI tracks it across all frames. Better for complex scenes with multiple subjects or when you need pixel-perfect precision.

Quality Winner: OBS Mask Generator (more precise tracking, better for complex scenes).

2. Workflow & Ease of Use

CapCut: All-in-one workflow. Import video → trim → remove background → add effects → export. You never leave the app. Great for creators who edit entire videos in CapCut.

OBS Mask Generator: Web-based single-purpose tool. Upload video → click subject → process → download. Then import to your editor (CapCut, Premiere, OBS). Best for creators who want specialized background removal before editing.

Workflow Winner: Depends on your workflow. CapCut if you edit everything in one app. OBS Mask Generator if you use multiple tools.
