SD card mp4 file read

Hi m_irshaid,

We'd like to help you find the best resolution path for this file issue. We recommend testing another file on the SD card to see if this is isolated to the file itself or the entire SD card. If this happens with all files on the SD card, try another external drive or SD card and see if this continues, and further test in safe mode with these steps: Start up your Mac in safe mode. We'd like to know the result of these test so we can help privet more clear and helpful guidance.

Hi m_irshaid,

Thank you for sharing this isolation. With this isolated to just this SD card, this would indicate the Mac is working as intended and there may be a compatibility issue or something we would not have any Apple resources on. We would recommend to check with the manufacture of the SD card and see what the limitations and expectations for your current macOS and model you are using. If you reach out and they determine no issues should be expected, you'll want to reach out to Apple Support. You can use the link below, if needed.
