I don't trust recording inside the instagram app again. I have fallen victim before and it was not palatable at all. Now, I have learnt. my lesson and in a very hard way. I record with my phone camera first because if one notification enters or the network misbehaves, my original video is still very safe. After editing, then I upload it quietly. That saves my sanity. I still can't forget the day there was a power failure while I was editing and my phone restarted. Just imagine if everything was done inside the app, I would have lost everything. Since then I don't even take that risk again.
