I believe I saw a post about this on vMix threads, but I am running into an issue where my picture looks ok when opening the web portal to my Spark, but the TriCaster squishes is down to 4:3. The camera I am using is a ReplayXD Prime-X (GoPro equivalent). The cam is set at 1080i59.94

Any suggestions on how I can fix this? It works fine on my Panasonic cams, but any of my action cams have this issue.
