  ```
  exiftool -m -overwrite_original -api QuickTimeUTC=1 -api LargeFileSupport=1 -tagsFromFile input.mp4 -All:All '-FileCreateDate<QuickTime:CreateDate' '-FileModifyDate<QuickTime:CreateDate' output.mp4
  
  ```
  
  On the other hand IINA and VLC should have no issues with playing any decent new or old codec.
