Video outputs stream and seek in preview
Job output downloads now support HTTP range requests, so large videos start playing and seek immediately instead of downloading in full first.
Previewing a large video output used to mean waiting for the whole file to download before it would play. The output download endpoint now answers HTTP range requests, so a player fetches only the bytes it needs. Playback starts right away and you can seek anywhere in the timeline without pulling down the rest.
This is a serving change only. The file is byte-for-byte what your job produced, with no re-encode and no extra processing. Every output format that a browser can play benefits, and existing download links keep working unchanged.
Range requests apply to every output, including the big files unblocked in outputs larger than 100 MB. Output handling is documented in job lifecycle.
