Hello, I have a big problem I would like to do a speedrun on ps4 but the broadcasting stops automatically after 1 hour so that if the broadcast is involuntary it does not last too long. But I'm forced to restart the broadcast because my speedrun lasts more than an hour. How can I do that?

This doesn't sound like broadcasting, it sounds like you're just plain recording on the PS4 with external memory storage which only allows for 1 hour tops of recording
