I am guessing there is no possible fix for this, but I recorded a 4K vide on my iPhone 7 that lasted for 4m 16 seconds. However, at around the 3 m 50 sec mark, the video is frozen but still plays the sound for a few more seconds before it is totally frozen. All of my videos are in the cloud so I was wondering if there is a way to try re-download it from iCloud where it may have those last seconds of video intact. I assume not, but thought I would ask just in case....
