.HEROThanks a bunch man! Well Besides skiing, I would like to video skating, and anything else I guess...but skiing and skating for the most part. Black Magic looks cool too. Would you recommend staying with the GoPro, getting a t4i, or panasonic hvx200a?
Cameras are only tools we use as filmmakers. A better camera won't help you tell a better story. That being said my suggestion to you would be to keep practicing. If I were to suggest anything I would definitely keep the GoPro for now. Its a great camera, its small and you can put it in places many other cameras would not fit. You can mount it on your skis, or helmet, dive down into water without the need for an expensive waterproof housing etc. Many people would take a T4i over a HVX, I on the other hand would take a HVX over a T4i. Its really all opinion and who you are as a filmmaker. Its hard to give you a straight answer on weather a t4i or hvx is better, so here is my quick opinion on the two.
HVX - Great camera to just pick up and go! Although P2 cards are still pretty expensive, they have came down tremendously in price over the past few years. XLR inputs, with 4 channel audio! This is a must have for capturing good clean audio! The camera will maintain focus throughout the zoom of the lens (meaning you can zoom into your subject, focus and zoom out and your subject will still be in focus). It has a viewfinder, and built in ND Filters! Unlimited record time (depending on your p2 cards), It does record 720/60p, but at 1920x1080 60fps the image is interlaced (1080/60i). This is a run and gun camera by all means, and can certainly be used more cinematically if you rig it up with the right equipment.
T4i - DSLR body, takes EF lenses, does not have built in ND filters, does not have XLR inputs, but does have a 1/8" mic input that you can attach a small mic to (or now there are many other solutions to recording audio directly into the camera), hard to maintain focus, 1080 up to 30fps, 720/60p, takes SD cards, you are only limited to recording 10:30 minutes per clip, each to achieve shallow depth of field. This is not a camera you can just pick up and run with. You need some kind of stabilizer at all times (Tripod, Monopod, Steadicam,MoVI), otherwise footage is very shaky.
I'm sorry if I missed anything in there, just writing from the top of my head. To basically sum it up, both are great cameras, the HVX has everything you need built into it, where the T4i you will constantly be building up. If you want to shoot action sports with a DSLR I would suggest getting a wide lens.
Please feel free to do a google search on these two cameras, being that they are two totally different styles of cameras. Again, sorry if I was not being clear on any of these topics, but I hope it helps you in some sort of way.
