Hmm, the Google Camera used to offer this. Haven't come across any other app that does it recently though. I'll keep looking.
Thanks Bla1ze. I appreciate your help. I film my dogs quite a lot and it would be great to find a pause feature as I like to make short videos with them doing cute stuff to send to friends versus having to take a bunch of videos.
I also missing pauze, because sometimes you wanted a different angle of just filming movements. Kids dancing sometimes just stop and then suddenly they start again.
