Vx + snow = ???
Would a sony vx be good for filming in the winter?, how would I keep it from getting wet
I am not familiar with that camera, do you have a link to a website with details?
Most of us have POV’s like Drift or Gopro for shooting in the snow. Water proof etc etc.
If you don’t have a weather resistant cam, just pick your days and you should be fine 
With a “rain jacket” or a plastic shopping bag tapped to the lens shield the Sony VX series of cameras handle snow/rain fine and last a number of years if your carful with your equipment - the ones I’ve used in the snow require a visit to a specialist repairer for maintenance every 3-4years.
These are popular amongst wedding videographer and you see many being used in snow and skate parks.
They are bulky and will restrict your riding and limit your day on the hill to just shooting.
It’s a “prosumer” camera (semi-professional).
Maintinance costs are about the same as POV action cams.
Unless you have a video business this type of camera probably isn’t ideal.
I own a similar canon (XHA1) - rarely will I bother using it in the snow because I can achieve much more with my DriftHD.
If your still considering the Sony VX (or similar) you might want to think about a DSLR that shoots video.
Yeh I agree that POVs are easier to use but I am over watching all fish eye/up close videos….looks heaps better when it is mixed up a bit ( I am very guilty of all fish eye clips lately so this is aimed at me as much as anyone).
Is that Camera actually High definition? I have an older 3ccd cam and the footage quality looks better then the older non HD cams but not as good as full HD cams.
Non POV cams are extra good because of zoom capabilities meaning you don’t have to be so damn close to the rider the whole time.
New VX cameras are HD - I think they are 3ccd
3ccd trumps single chip cameras even if the 3chip is SD.
Every year I do a live feed into a 20foot screen using a 3chip Canon XL1s (it’s 540i). After the performance I then mix it with 1080i footage (Canon XHA1). I prefer the footage from the XL1s - it has excellent glass!
