DaVinci 12 Resolve Studio 6K H.264 problems

Hello,

I am currently using DaVinci Resolve Studio 12 (v.12.2.0.013) as my color correction and transcoding software, and I'm having some trouble transcoding some 6k footage to h.264.
I'm converting R3D. footage at 6K (5760 x 3240) to several formats and resolutions using the deliver page on DaVinci, and until now everything went smoothly; however, almost every time I tried to convert my 6K R3D. footage to H.264 codec one of two things happened: DaVinci crashed with no apparent reason at the middle or end of conversion, creating no file, or the file created by the software had a 0kb size. I've tried doing this with grading and without grading (a very simple Rec 709 LUT provided by the software itself, with only a few minor changes using the color curves, so nothing heavy or fancy), but the problem persists. However, everything went perfect with the footage's transcoding to H.264 at HD, 2K, or 4K, so I'm guessing this is a 6K only problem... You'll find attached a capture log I made after these problems started.

Has anyone had this kind of problem, or has any thoughts about what it could be (except for a bug I mean)?

Thanks a lot!

is there a reason to be making h.264's @6k in the first place?

i'd question the entire concept... and i'd look in system logs for errors in QTEncoder/QTDecoder jsut before hangs/ crashes

but on earth who uses a 6k h264? if you are editing with 6k proxies then maybe use low bandwidth Prorez orDNx...

screeners at 6k for producer's? isn't it likely QTDecoder will gag on their mbp's?

H264 can't be 6K. Support ends at 4096x2304.
If you want something small and heavily compressed than it has to be h265.

The bigger question is who is editing in 6K or needs to see dailies in 6K? That way lies madness.

you cannot even see 6k dailies (then there is the whole thing about debayer and 6k being not really that)

4k/UHD will be the max format you will distribute anyway.

a good hd is good enough, the h264 in 4k will kill the resolution anyway.
