A real MKV video file whose audio track is your Opus, paired with a generated visual — a still background, the cover art, or a rendered waveform. Nothing is invented: the audio is untouched, and the picture exists only because a video container needs a video stream.

Only if the container requires it. Opus ní àwọn àkóódúrò àìdájú àwọn, and where the MKV container accepts that codec directly we copy the stream through untouched, bit for bit. Where it does not, we re-encode once at a high bitrate — audible difference is very unlikely.

Yes — choose the waveform visualiser and the picture is rendered from the actual samples of your Opus, so it moves in time with the audio. It costs more encode time than a static image but performs much better as social content.
Duration is limited by the file-size cap rather than by minutes. A static-image MKV adds very little per minute on top of the audio, so full-length podcast episodes and DJ sets convert comfortably; free accounts cover typical uploads and Pro raises the ceiling.

MP4 with H.264 and AAC is the universally-safe combination and what we default to.

Tags are copied into the MKV container metadata where there is an equivalent field. Note that platforms usually ignore embedded video metadata and use the title and description you type into their own upload form.
Can I convert a batch of Opus files into videos?
+
Yes — upload several and each becomes its own MKV with the same visual settings. This is how people turn a full album or a season of episodes into uploadable videos in one pass.
Yes — uploads are processed in isolated workers and deleted within minutes. Unreleased tracks and recordings are never stored, reviewed or reused. See /privacy/.
