Unable to export video as Apple Prores 422HQ in premiere pro

Hi,

I,Ramdas Gupta, imported one of my video footage which is already in 422HQ codec and I created a new sequence later when I completed my editing work, I tried to export in same format but unable to export it. I'm having issue with exporting video in Prores 422HQ in Premiere Pro

Kindly, help me out from this issue because I have to submit it in same format of 422HQ .

Thanks & Regards

Ramdas Gupta
