What specific mount can I use to attach camera on the window seal?
I'm trying to mount a camera setup on a window seal for a youtube setup. I have a window in front of me and would save floor space if I don't use a tripod. The camera needs to be about 14 inches (35cm) away from the window seal, but almost at the level of the seal. Maybe ted higher. So if I use this triangular mount from SmallRig I'd need to tilt it down quite a bit like in the second image.
But the camera needs to be level, horizontally, not tilted. I'm not sure from the photo if that ball head can twist upwards like that. That would be more than 90 degrees for sure. And probably even camera body wouldn't really fit in that kind of twisted corner.
I'm pretty new to rigging, so have no idea what to use. Is there some extra attachment that can solve this? Probably would need an extra knee or horizontal pole at the end. I could also use this type of mount. But same issue with camera twisting.
I could potentially mount it upside down? So the tilt is going upwards and not downwards making the ball head angle less than 90 degrees.
It needs to hold Sony FX30, light Sigma lense, and Elgato Prompter. Pretty heavy setup. Comes out to be about 4.5 pounds (2kg).
