Upload Method.

Your final export, prepared with purpose. Analyse, optimise and validate your video in one place.

THE WORKSPACE

Prepare your next upload.

Get a clean, validated MP4 without installing extra software.

Secure · Private · Browser-based

Sign-in required

Sign in with Discord to prepare a video. Your file is kept only while it is being processed and downloaded.

A CLEAR PROCESS

Four steps. One better export.

STEP 1

Analyse

We read the codec, colour, frame rate and audio of your file, and check that it decodes cleanly.

STEP 2

Decide

You pick a mode. The plan shows what will happen — and whether your video can simply be kept as-is.

STEP 3

Prepare

One pass, straight from your source. Compatible streams are copied instead of being encoded again.

STEP 4

Validate

The result is decoded end to end, checked for sync, structure and fast-start, then signed and handed to you.

Good to know

  • Accepted files: MP4, MOV, WebM, up to 500 MiB and 15 minutes.
  • Your video is stored in a private folder, is never public, and is deleted automatically — the result expires after 30 minutes.
  • Only you can see or download your own jobs.
  • This tool prepares a file; it does not post anywhere. Platforms may still recompress any upload, and no outcome is guaranteed.
