GoPro Hero 7 Black files are not uploading in Premiere Elements 2019

That too. But mainly is doesn't support the H.265 HEVC codec.

The codec for this file is identified as High Efficiency Coding. That's an H.265 codec (as opposed to the more traditional H.264 usually used to create MP4s).

The H.265 codec is not supported by Premiere Elements and will not edit well in the program.

same problem here, this is the media info text
