You put good info into your videos, but they can be up to 15 minutes long on YouTube. After that they have other things to sign up for, like even longer ones. Anyway, I've use Movie Maker (NOT to be confused with Windows Movie Maker, they are different!) for windows for years & it still works in Win10. All kinds of effects, fades, captions, titles, etc. Music too. And so far as intros are concerned they can make a video look a bit more polished, & my intros never last more than 28-30 seconds. But I'm aware of the ones you mean! Now if I just wouldn't ramble so much...lol. I use a cheap Targus 5' tripod from Walmart that cost me all of 13 or 14 bucks with carry bag. I got a used, but vgc Canon Powershot SX500 from B & H Photo (HUGE camera store in Manhattan) for about $70. It shoots HD video, uses Extreme HD Pro memory cards, & saves sound in separate stereo files. The 64GB Extreme Pro memory card saves about 55 minutes of constant video & stereo sound in way better quality than regular cards...with little or no degradation when uploading/downloading. The whole rig, camera, tripod & Pro mem card cost me about 130 bucks out the door. The still photos with it are fantastic! True HD video too.
The Movie Maker program saves your videos in the format used on the site of your choice; YouTube, Vimeo, Facebook, Twitter, etc. Easy to use & edit with. You can use it for slide shows or video.
