OBS Stinger cuts halfway

[roorider]

Using a 4 second .MOV file for my stinger
Stinger cuts around half way through for no reason (plays through in the preview but when switching scenes it cuts)
Tried 2 different pc's both running OBS 27.1.3 and both did the same

Have used a 1 second stinger before that works fine

any ideas??


Edit:
Discovered an MP4 will play fine as a stinger (doesn't cut)

Discovered that OBS just hates .MOV files...
went and converted to .webm and the stinger is now working
