Drop a video in — the MAP logo, header and tail are already loaded, so that is all you need. Click any of them to swap in your own. Output is a real MP4: Best quality at up to 4K (larger sources are scaled down), or a compact 720p copy for sharing. Everything runs locally on your machine; nothing leaves it unless you send the result to your own Drive.
Paste a Drive link to a video — or to a whole Drive folder — instead of dragging the file; several links at once become a queue, and Add a folder from this computer queues local videos too. Sign-in works with @maplaverriere.org accounts only. Batch results are filed automatically: Drive videos go to “Watermarked (done)” in ARCHIVES; for a folder from this computer you choose — beside the folder, to Drive, or both. A file too big for this browser goes to the 4K converter automatically, and when a run finishes a confirmation email goes from the signed-in account to the address under “Email when finished” (clear the box to skip it).
Discreet, but a crop of the edges removes it.
Same resolution as the source, quality first.
