Frame size setting in output exceeds the allowable dimensions of the HEVC codec
Googling this strange error has brought me no joy.
I'm on FCPX 10.4.10 (still on Mojave) and am unable to export my DJI Air 2S's video in HEVC at the original 5K size, though H264 and ProRes work.
Compressor's presets all max out at 4096x2160; attempts to set it to automatic don't help.
From everything I've read, 8K is HEVC's maximum, surely?
