For example, some but not all of the applications can import Sony XAVC and XAVC-S formats, which are used by Sony's popular DSLRs, mirrorless cameras, camcorders, and professional video cameras. The same holds true for the H.265 High Efficiency Video Coding (HEVC) standard. Most of the applications here now can import and export HEVC, though there are still a few holdouts.
