[SOLVED] Res numbers for 4K (2160) 21:9? I need help for movie studio 15

[danny009]

What is the res numbers for a 21:9 4K? for example it is (for youtube) 1280 544 but what about 21:9? I do want to put out on YouTube as in 21:9 but also in 4K

Thank you

You can't, youtube only supports standard 16:9 resolutions.
If you want to keep the 21:9 ratio upload it as is with the source resolution and youtube will pad it out accordingly, otherwise convert it to 16:9.
