It's been a few times that happened to me : I record a video sequencebut when I playback it's just a black image. The QuickTime is playing and the file is the length of what I recorded but there is no image! The infos shows normal datas like if everything was normal. I think this might happen when I turn off the battery too quickly after landing but I can't tell for sure. Does anyone knows why it happens? And is there a way to recover those files? Even VLC won't play it.
