I have recorded video for 1 hour on Nokia 5. It was 720p resolution. It's total size is about 4GB. After recording tried to play the video and it's not playing or shows any error. Just a blank screen showing. Even not playing with WMP and VLC on PC. Anyone facing this issue?
I did not try replicate the issue, but had similar weird behaviour when recording more than 1 hour in Sony's audio recorder.
I guess it has something to do with the streaming nature of the file and/or a limit in Android. It's on my curiosity figure-out list for next winter.
Can the file be loaded in a video editor?
Kdenlive is free software, Sony Vegas is solid but expensive. You may also consider take the video file along with pizza and cola to somebody who is used to work with video editing, or a local Linux nerd?
