The strange thing is that the alpha is not specified anywhere in the metadata so I understand why Resolve refuses to show the file as it sees data it doesn't expect.

I suspect the primary source is a bug in Quicktime, as the pixel format should be yuva420p to contain alpha information, not yuv420p.

Would transcoding the file be of any help??

(Edit: You can get around it with VP9, but I don't know if Quicktime supports that codec.
The alternative is ffmpeg -i Overheating.mov -pix_fmt yuva420p -c:v libvpx-vp9 -crf 0 overheat1.mp4 or your prefered ffmpeg frontend)
