Common questions.
How do I add a watermark to a video?
Choose a video, pick Text or Image, set size and opacity, choose a fixed corner or random moving position, then export. The mark is burned into every frame.
Can I add my logo to a video?
Yes. Choose Image watermark, upload a PNG or JPG logo with transparency if you have it, set size and opacity, and download an MP4 with your logo baked in.
What is random / Sora-style positioning?
The watermark jumps between corners every few seconds (2s, 3s, or 5s). It is harder to crop or blur out than a fixed corner mark — useful for screeners and paid previews.
Is my video uploaded anywhere?
No. Decoding, canvas compositing, and MP4 encoding run in your browser via Mediabunny + WebCodecs. Your file never touches a server.
What formats are supported?
MP4, MOV, WebM, MKV, and most common formats with a video track. Output is always MP4 (H.264 + AAC).
