Frequently asked questions
Does it track moving faces?
No — areas stay where you draw them. For something that moves, add several areas with different time ranges.
Is the video uploaded?
No. It's processed on your device with ffmpeg (WebAssembly).
Can a blur be undone?
The exported pixels are replaced, so the original detail isn't in the new file. For sensitive info a solid black box is the safest choice.
