Timeline masks
Multiple regions, each with its own active time range for watermarks that come and go.
Remove Watermark from Video
Draw boxes over watermarks, set when they appear on the timeline, and export a clean H.264 MP4 — audio untouched, nothing uploaded.
Lossless audio
Audio samples are copied through bit-for-bit — never re-encoded.
FAQ
Which video formats are supported?
MP4, MOV (QuickTime), WebM and MKV input — H.264, VP8, VP9, AV1, and HEVC where your device can decode it. Output is always H.264 MP4.
Is the audio re-encoded?
No. Audio samples are copied through without re-encoding, so audio quality is bit-identical to the source.
How long does processing take?
Region blur runs at roughly real-time speed or faster — about one minute of processing per minute of 1080p footage.
