chefsteps.com shows some good sous vide techniques. I trimmed up 2 whole beef tenderloins for Christmas about 2" thick, about 1 Tbsp butter, 1/2 tsp of SPOG mix, at 137 degrees for 1:15 hours. patted them dry, and seared the bejesus out of them for 45-60 seconds a side. My family said they didn't know steak could taste like that. Not sure I will make steak any other way...other than charred skirt steak, I love that stuff. Experiment, I'm still learning every time I use it. Still trying to figure out Chicken, I've done 148 degrees for 2:00 hours and then seared it, but I'm not fond of the texture. I still think high heat, brined chicken is the best. Good luck.
