exported h.265 project in premiere pro and uploaded to you tube...bad quality on you tube

I used iphone h.265 (HEVC) footage 1080P 60 frames second and exported it using premiere pro and after fiddling around with some settings it finally exported without any errors with the mp4 file with good quality. However when I uploaded the file to you tube it was very bad quality. So after research it appears that h.265 does not play well on you tube. So do I have to use a third party program like handbreak to change all my footage over to h.264 and redo the entire project all over again? Is there an easier way to some how take the clips I have in Premiere pro and convert them to h.264. If you any thought or have a link that Might help me with this issue it will be appreciated.
