The video files taken in February 20 19 are exported to PC. For example, the size of the original video file exported at that time exceeded 100 m, but I don't know when to upgrade to IOS 1 1, and the size of the video file exported again this year became 45 m.
What is the difference? There is almost no difference between the two files when viewed by the player and the naked eye. But when doing video editing, there will be obvious differences in PR, or catastrophic differences.
Apple believes that optimization and unauthorized decision-making are reasonable. After the video file in the user's mobile phone is optimized and compressed, there will be obvious phenomena of frame skipping, frame breaking, wrong frame and wrong order during PR editing, so it is impossible to play a complete video normally, let alone edit it. However, the original file of 65,438+000 m was put into PR, and the playback was normal and smooth, without any of the above errors, and the editing was normal.
Therefore, this is a serious problem. At present, the solution is to use video conversion tools such as format factory to re-convert the compressed video and output it again, so that the above situation will not occur during PR editing.
I wonder if Apple is aware of this problem.
