Fujifilm XT3 H265 HEVC Conversion Issue + Work Around

I have an XT3. I am shooting with the onboard recorder. So uncompressed available. F-Log / 4k / 60fps / H265(HEVC). When I drag that footage into Premiere, it runs slowly. This is not a surprise.

As usual, you want convert any of those highly compressed things, so If I use Adobe Media Encoder to transcode from H265 to Apple Pro Res 422, and it converts pretty quick.

When you look at that converted footage in Premiere (or in finder), all of the clipped WHITE is interpreted as BLACK. This is very strange. Shame on me for not properly exposing... but it shouldn't do that.

If I drag the original HEVC footage into Premiere, the colors are interpreted properly, though it is slow as HEVC.

When I transcode the HEVC footage in Premiere to Apple Pro Res, it transcodes properly. So, the bug is in media encoder. The work-around is using Premiere to individually do all your clips. Which is obviously a pain. But this isn't as fast as just the old media encoder drag and drop.

So the question is: Is there an interpret issue in AME or is this just an annoying bug? Any other work arounds?

Here's a thread on eosHD discussing this issue:

Tyvanharen​ that's great news - also see this massive long thread about it here:

WEIRD problem with zebra in Fuji XT3 video files. Help!

I have found that converting in Resolve (until adobe fixes this) works just fine - but I've found it to be slower than AME's encoding so hopefully they repair this soon. I haven't noticed any issues converting w/ Resolve like you have with Handbrake.

Hey dude, so I have literally spent 10+ hours on the phone and with Adobe remotely logged into my computer. I've sent them sample footage too, so that their software engineers can test on my footage on their computers. In short, it's a bug in the latest version of premier that is specific to H265 footage on XT3's. The ONLY workaround is to transcode your footage outside of Adobe (they suggested Handbrake) to H264 and then import it. This 100% works, but it's a pain. I've tried transcoding from within media encoder and whilst ProRes sometimes removes the artefacts, it's only temporary and the artefacts showed up later in the project (ie when grading).

It's a massive pain in the arse and Adobe have basically just said to deal with it and hope that it will be fixed in the next update of premier. See below email from their support:
