 [prores_videotoolbox @ 0x7f8963905c80] Error: cannot create compression
 session: -12908
 [prores_videotoolbox @ 0x7f8963905c80] Try -allow_sw 1. The hardware
 encoder may be busy, or not supported.
 [vost#0:0/prores_videotoolbox @ 0x7f8963905980] Error initializing output
 stream: Error while opening encoder for output stream #0:0 - maybe
 incorrect parameters such as bit_rate, rate, width or height
 Conversion failed!

 I'm on Intel Mac so I think prores_videotoolbox is not supported so it
 shouldn't be in the list when calling ffmpeg -encoders
