Above: The new Fuji X-S10 and Canon EOS R6 10bit mirrorless cameras do not play well with Adobe Premiere Pro.
Fuji users have probably – 90% of them – not been seeing the true capabilities of their cameras, because Adobe Premiere’s hardware acceleration doesn’t interpret the files correctly. As the EOSHD Dynamic Range Enhancer shows by fixing this, the full range 10bit H.265 files are heavily clipped in both the shadows and highlights. With the M1 processor, this seems to be improved due to Apple’s new hardware acceleration but the issue has been plaguing Fuji users for years on Intel, Nvidia and AMD systems.

The other problem with Adobe Premiere is the lack of hardware acceleration for Canon’s 10bit 4:2:2 H.265. This is the format Canon has used for C-LOG recording on the new mirrorless cameras like the EOS R5, and the Cinema EOS C70. Even on a new M1 processor, I find that files fail to playback at all and buffer constantly – and this is just a single clip on the timeline without any effects or grading applied.
There’s a reason Fuji chose 10bit 4:2:0 for their HEVC codec implementation on cameras like the X-T4 and GFX 100 – Nvidia and AMD GPUs don’t support hardware acceleration of 10bit 4:2:2 H.265. So did Canon not realise this?
Either way, Canon EOS R6 and R5 users are stuck with uneditable files that have to be transcoded to another format to be usable in Adobe Premiere Pro.
