I was given a little go pro type camera but when i load the card it says cannot read Quicktime videos

The manufacturer(s) seems to to use third party online stores exclusively, with very little documentation and no external links. It seems to use a TF card/​microSD, up to 128 GB (sold separately). It seems to write AVI files with H.264 video.

QuickTime Player doesn’t read AVI files (anymore). Try a different media player software (e.g. VLC), or convert to a format (.mp4) that QuickTime Player likes better (through e.g. HandBrake).

Please identify the camera and model, so that manufacturer specifications can be looked up.
