Add timed blur, pixel or cover masks and mute or bleep sensitive audio.
Use the guide alongside the working tool.
Open Video Blur & Bleep →Cover a visible address
Export range: 0–20 seconds
Address visible: 5–12 seconds
Mask: opaque cover
Mask time: 4.5–12.5 seconds
Audio: mute the spoken address intervalLeave a time margin and check every frame around the entry and exit. A fixed cover only protects the area it occupies; if the address moves outside it, enlarge the rectangle or add another appropriately timed mask.
Create and export
Choose a video and the export range. Add a mask, select blur, pixelation or an opaque cover, and set its rectangle and active source times.
Add audio intervals for mute or bleep. The original audio is suppressed inside those intervals; overlapping bleeps use a union so overlap does not intentionally double the tone.
Render and review the entire encoded selection before sharing. Fixed masks do not follow a moving subject; use an opaque cover and sufficient time coverage for sensitive information.
Methods and limits
Videos up to 50 MB and 10 minutes; export a selected range up to 2 minutes at up to 720p. Up to 8 fixed rectangular masks and 8 audio intervals. Masks do not track moving objects. Review the encoded result across the entire range before sharing. Blurs and pixels are not guaranteed anonymization; use an opaque cover for sensitive information.
