If your goal is to make money, starting a comedy youtube channel doesn't seem to be the obvious choice. There's lot's of competition and little money.

I'm curious about whether sex sells

But why would you investigate that by comparing promotion using attractive models (note: the fact that "model" has two quite different meanings is one reason why it would have been helpful had your original question been a bit more discursive) with random means of promotion? What you actually want to know is surely something more like: If you take some means of promoting a thing, and then make the minimum possible change to it that adds or removes a substantial amount of sexiness, what happens to its effectiveness?

sometimes my comments become redundant when a commentator rephrases or restates all points of interest

This is not sufficient reason for deleting them, any more than the fact that an employee has been made redundant is sufficient reason for killing him.

By all means edit your comment to add a disclaimer -- put it at the start if you like, to save readers' time -- but please do not delete the original text. If nothing else, it provides necessary context for understanding the responses.

Something you could do, alternatively, is use software like facerig, assuming you have a webcam. It would work fairly effectively, I think, and is comedic enough in its own right to go along with your show.

I've no clue myself. My minimal expertise in computer specs is 5 years old; the last time I payed attention to them was when I built my current computer (and even then with parts recommended by a friend). However, I've long since delegated figuring out if my computer can run something to Can You Run It. It functions fairly effectively in checking that sort of thing.

This new example video is much better. If I wasn't invested in watching it in order to assist you, I would have clicked away from it after about 45 seconds rather than 5, and then mostly because of your pausing speech. (Many YouTube creators cut out every single inbreath, and I suggest you try that.) The music made a surprising amount of positive difference, and I actually like the picture a bit - I hope you have rights to use both?

Of the visualization options you name, I figure a nature image, possibly with a textual description, is the least bad option. But really, not showing your face cuts down your appeal by at least 90%. As long as you don't do that, your problem isn't in the marketing, it's in the product.

I'm not suggesting background music, although it evidently helps. I'm saying that when I watch videos, expecting to hear enjoyable music is frequently my main motivation. And since almost all of the most-viewed videos are music videos, that's obviously a common motivation. Your video is not adressing that motivation, and background music is unlikely to change that. Nor is it adressing the common motivations for personal connection, interesting or actionable information, or something pretty to look at. You could get at the personal connection bit if you made jokes about (what you claim to be) true stories from your personal life and - did I say that already? - show your face.

To me, your banner looks simply cheap. It signals you're not committed to making me have a good time. Yes the clouds help a bit, but I'm sure you could do much better.

A one-liner (or better yet, three good jokes in the first 20 seconds to build up expected entertainment value for the rest of the video, and keep me watching) will help even without a face. A face would help more. Compare this: https://www.youtube.com/watch?v=FHczVzGfyqQ . The guy isn't conventionally pretty, and the video is clearly not about visuals, but still, he wouldn't have gotten over 300K views with a goddamn static visualisation.

And yes, people will make stupid hurtful comments about your face, even if you're the sexiest person on the planet. Growing to tolerate that is one of the best reasons to make videos.

Descriptions will occasionally make me invest a couple more seconds in a video, i.e. make me give it a couple more opportunities to get me hooked.

These files will be made regardless of whether there is a YouTube channel hosting them

Why? What your purpose for creating them?

You don't articulate a purpose.

You're giving me no relatable subject I could be interested in, nothing pretty to look at and no music. Literally the only hint that lets me expect anything good from this channel is the word "Comedy" in the title. And when you fail to give me a good joke in the first 5 seconds, my expectation for funniness from the rest of the video goes way down. This means no expectation to be entertained is left, so I leave.

Your voice is good though, and the sound quality is fine.

Minor points: You talk too slowly, except in your first video. Your channel banner is repulsive. The visualizations you use are both ugly and getting worse; the newest one is downright painful to look at. (Seriously, an unmoving image would do less harm.)

If you show your face and drop a quick one-liner right at the beginning and talk a bit faster, this might be going places, otherwise I don't think you have a chance to be talked about for this, let alone make money.

You fail to say what the videos are about. That's bad for any venue that you want to market.
