About this conversion
What happens
Video is discarded, metadata is removed, and the isolated output is validated before a one-hour download window opens.
Limits
250 MiB input. 15 minutes, up to 3840×2160, and 100 MiB output.
Things to know
192 kbit/s is the balanced default. Raising bitrate cannot recreate detail missing from the source audio. Files without audio, unsupported/corrupt streams, excessive duration, queue capacity, or validation failure are reported clearly.
