Frequently Asked Questions
- What's the difference between solid, pixelate, and soft blur?
- Solid fills each face with a flat dark color across every frame — strongest privacy, zero detail. Pixelate applies a tracking mosaic. Soft blur is the gentlest — face shape stays recognizable but features are obscured. Solid is the default for journalism / GDPR use; pixelate is the classic 'TV documentary' look.
- How long can the video be?
- Up to 10 seconds for free users. Pro plans extend this limit. The AI tracker maintains face identity across frames within a 10-second window; longer clips are processed in chunks.
- What if a face turns away or gets occluded mid-clip?
- Our video tracker handles brief profile turns and partial occlusion. If a face disappears entirely (walks out of frame) and comes back, it may be picked up as a new instance — still redacted, just with a fresh tracking ID.
- Is the audio preserved?
- Yes — the original audio track is muxed back into the output video.
