QT & H264 encoding in FCPX not working.

[0ChrisLambert0]

Hello Everyone

Congrats on having such a fantastic site and helpful community!

I have managed to avoid for the most part posting stupid questions and attempted to do my own research to help keep the road clear for others in a easily confusing topic but have recently come stuck with FCPX & QT.

In FCPX on both the previous version and the new 10.4 I am unable to export a file in H264.
"The operation could not be completed because an error occurred while exporting (error -12912)."
I am ok to export in every other format tried including the new H265.

Today I was attempting to screen record my setup and QT has been crashing. I am presuming due to the same issue.

My setup is

gigabyte z170 ga-z170x-ud5 th atx
Intel 6700k
AMD RADEON 480 8gb (Internal graphics is disabled, I have tried auto also but this does not appear to work.)

Can anyone shed any light on this? I am assuming this is a quick sync issue, onboard encoding related but then why would h265 be ok?

Thanks and If this is a newbie error I apologise.

Chris

I just tested this myself and I got the same problems as you when running with just my RX 560. I then turned on both integrated graphics as well as my 560 and both screen recording and exporting as h264 worked.

What SMBIOS are you using? I'm using iMac18,3
