BUG: Clips still moving at faster than normal speed when viewing

bug

#1

I’m now experiencing the issue where when viewing an alert video, the playback is sped up. I thought this was fixed a while ago but either it has come back or just decided to hit one of my cameras. It’s not doing it on them all.
The camera in question is on firmware 4.9.3.60 and says it’s up to date. I have other cameras on the same firmware that do not exhibit the fast playback problem.

Not sure what to do to try to resolve this.

Thanks.
