Export codec_tag setting for HEVC

Help/How To

Problem

In order to be compatible with Mac Quicktime the video codec needs to be labelled as HVC1.

Shotcut by default exports with the following codec tags:
codec_tag_string=hev1
codec_tag=0x31766568

Quicktime needs the following codec tags in order to display the HEVC video:
codec_tag_string=hvc1
codec_tag=0x31637668

I’ve tried selecting the Shotcut HEVC Main Profile and adding the above parameters to the Export --> Other section however this does not seem to work.

Does anyone know how to change the codec_tag settings in Shotcut?

ffmpeg workaround

The following ffmpeg based workaround exists:
ffmpeg -i input.mov -c copy -tag:v hvc1 output.mov
