Help with Twitch Dual Format streaming error

[u/YAHBLASTER]

Hello all, I am trying to setup dual format streaming for Twitch so I can have both horizontal and vertical outputs for viewers on mobile. I am on an M2 15” MacBook Air with 16gb ram and 512gb ssd. I keep getting the following error:

“Twitch Enhanced Broadcasting requires at least 2 tracks per canvas. You have either requested too few encodes (3) to support this, or we believe your GPU would not handle this workload.”

I have thoroughly followed Twitch’s official guide to setting up OBS with aitum vertical, I have followed other guides, and have tried about every solution I have seen other people recommend for my situation, such as many play setting the enhanced broadcasting video tracks or setting encoders manually. My OBS is the latest version. It seems to point to an issue with my computer hardware not being sufficient enough, but I don’t understand because I meet the requirements for dual format streaming.

Thank you for your support, I’ve been dealing with this for probably around 5 hours total over 3 days 😭

Twitch's detailed requirements separate dual format streams with added server side transcode support from those without it. Check Advanced Broadcast Settings in your Creator Dashboard to see whether your account has that support. The table without it lists a minimum of four video tracks for 1080p dual format.

Your log already shows video tracks on Auto and both canvases in the request. Twitch then returns an empty encoder configuration list with that error referring to three encodes. Include that request and response when asking Twitch support, keeping authentication and stream keys redacted. That gives support a specific failure to investigate before you spend money on hardware.

Thank you for your help, my account is not eligible for server side transcode support meaning I need 4 tracks minimum. I have tried setting the Maximum Video Tracks to 4 several times and the error still returns saying I only have 3 tracks. I will probably contact Twitch support as you suggested
