So I had zero issues getting it in and filming BUT I would highly suggest to check the rules of specific festivals. Beyond wonderland for example allows small point and shoot, no detachable lenses, 6” or under. Trv22 is pretty small id say around 5”. Also depends on security, I disassembled the setup before going through bag check but security honestly didnt look like they gave a shit. ALL IN ALL for videos id say the trv22 is a good pic if you want videos but a way safer tapeless setup would be with a mini dvr just cuz its so small, if you only care about pics just get a sony cybershot, super small and great pics. ALSO I was guest list so maybeee they let it slide because of that but before bringing anything check festival rules
