Problem
Automatic VOD processing produces an incomplete or delayed archive after a stream ends unexpectedly.
Solution
Root Cause / Diagnostic:
When a live stream terminates abnormally (due to a power outage, internet disconnect, or encoder crash) without the operator clicking "End Stream" in YouTube Studio, YouTube's ingest servers wait for an RTMP reconnect timeout before closing the session. In ungraceful terminations, the final video chunks may fail to finalize, resulting in a truncated archive or indefinite processing loops.
Actionable Fix:
1. Always manually navigate to YouTube Live Control Room and click "End Stream" to initiate a graceful session teardown once an unexpected disconnect occurs and cannot be restored.
2. Configure local recording in your broadcast software (OBS/vMix) using the MKV or fragmented MP4 container format, which prevents file corruption even if the computer crashes abruptly.
3. If the automatic YouTube VOD archive is truncated or corrupted, use the local master recording to re-upload the complete, polished broadcast as a dedicated VOD upload.
Pro Tip:
Never record locally in standard MP4 format for live productions; if power cuts mid-stream, standard MP4 files lack the finalizing moov atom and become completely unrecoverable, whereas MKV or fragmented MP4 files preserve every second recorded up to the crash.
