It looks a little busy to me. My rule of thumb is humans can memorize up 7 things at one time and then forget half by the next day.
It looks a
lot busy to me. Professional speakers know that you should have no more than three main points to make in a speech. If you have a "laundry list", then your audience is going to forget most of what you say.

I'm reminded of this story told by my stepfather, a Protestant minister (and a Doctor of Divinity):
A minister who was a member of the local Rotary club was asked by one of his fellow Rotarians if he'd be willing to be the main speaker at a meeting, and if so how long he'd need to prepare.
"Well," he replied, "How long would you like me to speak?"
"How about 15 minutes?"
"Oh, I'd need a couple of weeks to prepare."
"Well, what if we wanted you to speak for 30 minutes?"
"Oh, I could get ready for that in a week."
"What if we wanted you to speak for two hours?"
"In that case, I can start talking right now."

I'm often reminded of that joke -- which has a real point -- when seeing links to some "Ted Talk" which goes on for like 85 or 90 minutes. Seriously, the speaker has something to say which he thinks is important, yet he couldn't get his remarks down to under an hour? Either he needed more time to prepare, or else he doesn't understand that when giving a speech,
less is more. Ditto for the narration in a video.
Now, there are certainly cases where more than 15 minutes is necessary; if you're doing a detailed instructional video, for example showing all the features in a new EV and showing how to operate them, then it may be necessary to go rather beyond that 15 minute limit. But if you're trying to explain a general concept, such as what type of car (gasmobile vs. PHEV vs. BEV) best suits someone's lifestyle, then get it down to 15 minutes. If you need more time, then you're trying to cover too much in a single speech, so break it up into multiple videos.
History's most memorable speeches aren't the ones that went on for hours. Rather the opposite! Lincoln's Gettysburg Address is only 272 words long.
