I am at last getting to sort out my video files, since having had to recover them after my extreme senior moment.
Some have a thumbnail that is a preview and will play properly, whilst others' thumbnails are just the icon. Some of the latter will play, others not.
I understand that the unplayables will be corrupted, but not how some of the playable ones produce a preview thumbnail others not, the media detail being the same.
The left side of the attachment is an example of both versions of the playables, the right those that fail to play.
Comments?
