On the requisition candidate view, you can access an option called "Re-encode responses", as seen below
When you select "Re-encode responses", the original interview responses are sent back to the interviewstream encoding servers, which combines the audio and video recordings and formats them for playback.
If you experience any issues with video or audio playbacks, it can be worth trying the re-encode responses option, as this may resolve any issue experienced with this feature area.
Selecting this option is harmless, and will not result in data loss.
This option can be used as a possible solution for issues with interviews stuck in processing status, as discussed in this article
If your issue is not resolved by choosing this option and allowing 1-2 hours to pass, please contact support.
