Using the profile in Tricaster for restream get the same issue. How do you change keyframes.

Restream 860 AE3 1080/50i
Tricaster 860 AE3 using
Using the Tricaster encoder preset
When I stream I get the following error message from Restream dashboard.

Check you encoder settingsflash
Keyframe interval: 1
Recommended: 2

Where do I change this? I've also noticed some audio drift on this on youtube at 1080/50i

Thank you
