Anyone diving a Canon ELPH 300HS? Quick question!

[Coll]

So I just bought the 300HS, it looks and feels great, very intuitive. I haven't gotten a chance to take it sub surface yet (Still waiting on Ikelite housing in the mail) but as I was messing with it, it seems that the manual white balance setting does not apply itself to video. Obviously this would be problematic since the video will all come out poorly colored, does anyone have a solution to this? I can get the WB to set for pictures but then I took a video and it was all auto colored.

Thanks for the help and if anyone is currently diving this rig I was love to see any pictures or get any insider tips/tricks to the set-up. Happy diving all!
