I cannot see video files on conected camera only photos
On my Camera I have both photos and video's on the SD card, when I try to access them through what ever method I only see the photos to import.
They are definitely on the SD card as I can see them on the camera, only when the sd card is in it. I have tried to use the cable link to the camera and that gets the photos, but videos are not there. Have also tried inserting the sd card directly into an attached card reader. Even tried on my old MacBook pro which has a built in card reader - in both cases finder shows photos but not the video's.
I am wondering if it might be to do with the Norton AV I have recently installed.
Would be grateful for any advice.
MacBook Air 13″, macOS 11.6
