I am currently living the life as a ski bum, and take a lot of video with my Gopro HD. I want to be able to do some editing to the videos I take, so I used Pinnacle Videospin to chop up my first video. Problem is, when I put the 1st video up on youtube, the maximum youtube would give it is 480p, despite that the video modes used for that video are 960p (960 tall in 4:3 aspect) and 1080p. My 4th video I put up straight as it came off the gopro, without editing of any sort (in 960p mode), and youtube allowed 720p.
Videospin also added some weird noise to the video when it transcoded to make the final clip, you can't see it in the youtube video at 480p, but in my local copy it's pretty obvious:
Apparently the problem has to do with the transcode itself, so I would like to be able to skip the transcoding if at all possible. Vdub is apparently able to do that, but 1. I can't get it to open the gopro's mp4 files no matter how many internet guides I follow and 2. I'm not even sure it has a powerful enough feature set to do the thing I want.
The editing I did on the first video was kind of just to figure out what videospin could do. I have previously done editing on a mac for a school project, which had tonsss of editing and splicing together. I would like to do something similarly edit-happy in the future, as there is a video competition coming up for a newly-opened area of terrain, the Superbowl. I probably won't win with just POV footage, but I would like to give it a good solid attempt. From what I can tell, videospin doesn't have the effects I want (most notably fast-forward).
So, what software should I be using? It needs to be able to transcode in such a way that isn't ultra-lossy or atrifact-inducing, needs to have a decently beefy feature set, and needs to be able to open mp4 files.
