I feel like you guys have it already sorted but just a TL;DR version with steps:
1. Make sure the move, line, obstacle AND RIDER (100% of his/her body+ bike) are all inside the frame of the video, so we can actually see what just happened and what the rider did, not just filming the wheels or the shoes. Step back and make sure we can see wtf is going on.
2. Pick some non-cheesy music (if you're adding music)
3. Use of slow-mo should be tasteful, we don't need to see a slow-mo 1 meter gap and 2 minutes of rear wheel hops because they were all captured in slow-mo.
4. It can be commercial but just tell the people filming that the viewers will want to be able to see what just happened, and will also want to see a 90% riding video.
5. It does NOT have to be a movie production with storyline, etc. Refer to Borisevich Pavel's older videos, CLS, Ali C.
6. Not required but good for reference: latest amazing videos are ones from Mark W.
7. Dress like a proper human being.
And some people will hate me for this but if you see Danny Mac's videos, yes they are over the top productions but you can see what he's doing, even if you don't like his riding style AND they're all about someone riding a bike.
If I missed something let me know.
