how in the world do you edit video? i purchased vegas 9 to edit ski videos off my HD. when editing it doesnt give you real time video. only audio. you will get about 1 frame viewed every 90 frames. that basically one picture of someone approaching a wave and another of them riding away from the trick. its impossible to edit or even know what things to edit in or out of a video. i wish i could return all this crap.
Do realize the gopro hd cam's H.264 output files are one of the hardest consumer level formats for an editor to deal with. It isn't even compatible with some of the best editing software out there so do expect some major inconveniences for the ones it does work with. There are a couple of options to work around this though.
For navigating the mp4's, use the keyboard shortcuts j,k,l (reverse play, pause, forward play) and the left and right arrow keys (back x frames, forward x frames). JKL gets you close to your cut point, then the arrow keys can get you to the exact frame you need. They will skip by different amounts of frames each keystroke depending on how zoomed in you are on the timeline. You can change your zoom with arrow up and arrow down. Get proficient with these shortcuts and it really doesn't matter how choppy the preview is.
The other option is to get your footage into vegas and then do a file>render as... . Use the save as type 'Video for Windows' option and, if needed, hit custom and change the settings to make sure it outputs in the same exact format as your input. For example, if you film at 60fps (which I hope you are) it will default to 30 and you'll have to manually change it to 60 in that custom dialoge. If you don't have one, a good program to tell you all the specifics specs of any video file you have is GSpot. Be carful when you google for that one, lol. With the hd file saved in this format it should preview smoothly in vegas given your computer is fast enough.
Long story short, be made at gopro, not vegas. Also, there is an abundance of tutorials on youtube for vegas. I strongly suggest spending some major time watching those before you spend too much time editing.
