Looking at the first footage you put up, it maxes out at 480p which is not a high def resolution. That makes me think that you did not edit in HD, so it would be the project you were working with, not the footage. As far as what file format to save to, someone said that wmv was an issue but for you, it shouldn't be. I've directed commercials that were delivered to the network in WMV and they will work fine if done correctly. That said, goPros will get very grainy in low light and don't have a lot of latitude in their exposure. If there is too much of a range between the light and dark in the image, you will blow out the whites, block up the darks, or both. You have to realize that it just isn't a high quality camera, but has it's time and place. I have used them in places that a movie camera would not fit and with proper exposure, been able to use the footage in a movie. Another thing you have to watch out for with the goPros is the jelly image that comes with shutter roll. This is really a weak point with cameras that are sold as a means to record action. Shutter roll in digital cameras is what happens when the frame is not recorded all together but pixel by pixel, line by line. This means that the entire exposure of the frame happens over a length of time, not all at once. While the frame rate may very well be a 30th of a second (for a goPro, not typical of a film camera which is 1/24th) and the exposure may be considered something like 1/60th, each frame may take closer to 1/30th to expose, section by section. That means while something is moving quickly through frame, it will not be in the same place while each individual part of the frame is captured, making the image look like it wobbles like jelly.
