Is there anything else you'd like to see? Body position? Throttle application? Trail breaking? Suspension setup?
My request is that you use and spell the term "trail braking" properly. You want to use the brakes at the track, not break anything while there.
As for the video quality, there's likely not much you're going to resolve with the on-bike setup. For me, the quality comes into play more with a stabilized set up not the overall resolution. Not a bouncy, jerky, wide-angle video stream. I'm talking about smooth, full-frame, and focused video on the subject in question.
I run my cameras in HD settings of 1280x720p and skip the 1920x1080 resolutions. This is due to the frame rates of the 720p at 60Hz versus 30Hz which allow better video at higher speeds with less blur. Add to that that the slow-motion capture aspects at the 60Hz rates, and the higher resolutions really aren't needed. So you may try more of that.
Also, I would think the edge-of-the-track camera looking would help augment the video rather than just all the on-bike footage. If you have the capability to set up a tripod off track and take some shots, that would add to your videos depending on the topic!
And yes, video production is a long process. I've spent well over 100 hours of labor to try and produce a 1 hour video. It's time consuming to sort, review, layout, edit, and produce good videos! Keep at it though!
