What software do you use to edit?
I bought a sony action cam a month or so ago. It's pretty chunky but the picture quality looks to be decent. Am heading up to lake louise within a couple weeks will be good to test it out on the snow.
Cyberlink powerdirector 9 I believe. I've tried Windows Movie Maker but found it locks up a lot. PD9 is actually relatively easy to work with, and I've got it outputting in M2TS format now which doesn't seem to process the video as much. Actually the video produced looks pretty good, but when it's uploaded to youtube it seems to really get shitty.
Was looking at the Sony too recently, I feel like in another generation or two ALL the cameras will have high FPS rates at the lower price point.
You should have fun at LL, there's pretty good cover in most places. Even if no new snow falls there's still fun to be had there. If you get new snow it'll be great!
