If I had a dollar for every shooter buck I've had on camera in the last four years I'd have about $100 dollars. If I had a Dollar for every one of those bucks I shot then I'd only have $2. Just getting a buck on camera means nothing other than he was there at one point. It takes a lot of effort get your hands around the antlers than it does to get a picture. I have hundred of hours on the stand that prove that.
They are good bucks and both shooters in my opinion. In velvet, they look a lot bigger in my opinion. If they are bucks that you would be happy shooting then they are big enough and old enough to shoot. I know I wouldn't hesitate!
