A recent encoding change caused a mismatch in initialization metadata for some clips that were created in the last 24 hours. This would affect clips of assets created before Thursday, March 6 — 15:11 UTC that utilized "basic" or "premium" video_quality. A fix is currently being worked on.
- resolved Mar 07, 2026, 01:57 AM UTC
Engineers have resolved the issue with clips not having audio. Any new clips will function as expected. Impacted clips created during the incident window are not retroactively corrected, but can be re-created from the original asset.
