I have MP4 clips from my new DJi drone and they play with VLC but wont load to the project bin just goes blank, but why I though KDENLIVE was capable of MP4?

KDENLIVE REPORTS IN CLIP PROPERTIES :- H.264/AVC/MPEG-4 AVC /MPEG-4 PART 10
In properties on the clip shows just MP4 Video file

The funny thing is which I cant work out if I convert from this file to a MP4 again it works and Kdenlive reports same type of file?

Files from DJI mini 2 works fine here, using kdenlive 21.04.3 on Arch linux. They are quite heavy, so proxy generation takes some time, but as soon they are done everything is fine.
