Crashes and crashes – Video BlendEr -Free Double ExpoSure EditOr SuperImpose Live EffectS and OverLap MovieS Review

2 sec length vids - 1 sec length vids - nothing works using iPhone 7Plus using latest OS update. Tried non HD, and small file size. Nothing works. Wish to give it 5 stars, not 1 —- Frustrated!!
