@jonottawa Good work with the content jon, I looked over your channel and you seem to be quite dedicated to pushing out videos for URW. I have some suggestions in regards to how you could possibly improve the quality of your videos;
1. I'd suggest maybe highlighting specific parts of your play through videos that seem particularly interesting in terms of gameplay as seperate, shorter videos (like you've done with this one, albeit specifically as such and not from random gameplay), and then doing a voice dub over the video to evaluate and discuss it, I believe you'll have an easier time perfecting what you're trying to discuss in relation to the video as you can always replay your cuts and think about what points you want to underline easier than on the fly commentating, should also open up more options when you're editing your videos (if you use some editing software) in terms of sound and overlaying stuff you want to discuss.
2. The sound quality isn't particularly pleasant, at least for me I find it harder to listen to. I don't know if it's just your mic or what, but I can hear your voice all over the room as sort of a background tone, might just be the location you're streaming from. Wouldn't hurt to experiment and see if you can reduce the background noise.
3. I haven't looked at too many of the game play videos, but one thing I notice that keeps the attention of viewers are long term goals with planning, and the explanation of why you're doing particular things to achieve particular goals or milestones.
4. To cut down on video length and increase the quality of your videos, I would remove boring parts of gameplay that aren't too exciting such as traveling from point A to point B, grinding/processing a lot of the same material, I believe cropping redundant tasks and highlighting the most rewarding parts of the experience will give you higher quality videos. Nothing wrong with full gameplay videos though, but I think people will find your content easier to pick and choose from with more organized cuts, and reduced video length, as most people like to watch videos between 5-40 minutes in length depending on the videos content.
Overall, I think you should focus more on polishing the content after/during recording, and make particular highlights so each video stands out as its own, currently you have a lot of gameplay videos, which can be fun to watch, but you have so many of them at such high lengths that the average person looks at the them and isn't sure which is going to be worth their time sifting through, where as shorter videos with a particular focus will give someone the most bang for their buck on a particular mechanic or subject in the game. Another thing you could consider, is combining clips from multiple videos in the case of explaining a particular mechanic or concept as obviously you wont be doing the same thing everytime you're playing the game, but you can accumulate a lot of clips where the situation occurs and combine these clips to create a video where you can explain each part of the subject in greater detail, and with far less subject change.
Anywho, I hope this can be of some help for you, obviously you have the passion to produce the videos, so if this helps improve that process for you in any sort of way I'm glad I could be of help in your future creative endeavors.
