Nice video Chris.
I'm not a photographer, director, producer, editor, marketing professional, or anything like that. I'm just a Joe who loves aviation and flying, but, since you're asking for help, I'll give you some observations and critical feedback that is purely my opinion, but hopefully useful to help you improve your final product. I am at no time attacking you and don't mean any offense by anything. If something I said offends you, I apologize in advance. You are free to take my observations and opinions or leave them.
I love the in-flight footage. The narration and the music go nice together too.
On the whole though, the video seems a bit cold, distant, and impersonal. Kinda Joe Friday-ish, just the facts. Adding some people smiling, laughing, and generally having a good time in the airplane would probably help with that. It might sound dumb, but in my 40-something years of life, I've learned that people will forget what you told them or showed them, but they won't ever forget how you made them feel. Get them excited. Get them involved. Make them want to see themselves doing that and feeling like they are joining a small community of pilots who know and experience something fun, special, and amazing that nosedragger pilots will never get to know or experience.
Maybe you could also find or make some pics/video of people having a good time, chilling out around a campfire or fishing in the backcountry with an airplane or two in the background. I might be biased there; escaping congested and controlled airspace, paved runways, radio traffic, and crowds in search of freedom, peace, quiet, adventure in nature, and landing on airstrips that aren't even airstrips is one of the main reasons I want to get a tailwheel endorsement.
At the end of the video you have like 15-20 seconds where you put up a boring list of what you just told them. It seems like lazy, "filler" material hanging there, marking the end of the video. At that point, I stopped listening and started reading the video shot instead because you lost my attention. I'm not talented enough to read and listen at the same time, so that's on me, but that would probably be an excellent opportunity to put in video and/or pictures of happy pilots and passengers laughing, smiling, waving, and having a good time while you continued your narration.
If you wanted the viewer to see the reasons written on the screen, I suppose you could just very briefly put the word, Aerobatics at the aerobatics scene, Warbirds at the warbirds scene, Gliders...broader employment opportunities, etc.
I didn't see your contact information anywhere in the video. The beginning had a small block that had Chris Dupin KCAB in the bottom left hand corner, and your copyright tag stays at the top right, but there's no link, email, or phone number to contact you, or to use to find a CFI nearby someone that they can use to get an endorsement. Maybe that was intentional, or maybe it was accidentally left out. It just seemed weird to me that a promotional video didn't have any means for an interested viewer to follow up with.
Also, at about 1:00 into the video you use the term "Private Pilot Rating". Have you thought about editing that to "Private Pilot Certificate"?
All that said, I think you have made a GREAT start with your video. I really enjoyed watching it!
