Hi there, sorry for all the trouble that it caused. This is not the experience we want you to have with DJI. Please make sure to download the original footage directly from your SD card and check if the issue persists. Also, kindly upload a sample footage of this concern for further checking. You can upload it by using google-drive or Dropbox and provide the link here.  Thank you.
