Ha ha, a progression video would be cool. Your videography skills are better than mine. Can you take multiple videos and meld it into one progression video? I like how you add text in your videos also, I don't have a clue how you do that!
I use my iPhone for pretty much all of my video creating. I'm sure there are lots of apps out there, but I use iMovie. You can bring in multiple videos or pictures, insert text, etc. It's pretty easy to use, I think. If you have a droid, then there may be their version of the same app on your phone. Basically, in the app, you create a movie project, and then when you're finished, you can save it to your photos/videos. You have to make sure that you have storage enough to save it. That way, if you have a goal in mind for your video, you can plan it out and shoot segments, etc.
If you use a GoPro, then they have software for that stuff too, and export that to your photos. From there, you can bring that video into iMovie.
If I have to do a voice over, iMovie can't do that (as far as I know), so I use Rush (an Adobe product), but there are other apps as well.
So, for a progression video, I'd have to use pictures to start with, then use voice over or text to explain, because I deleted a lot of my original videos off of my phone to make room for new ones. I'm like a pack rat, save everything LOL.
BTW, I finish up my videos on my PC, because in YT on your PC, there are more options to choose from than the phone app, like adding a thumbnail. You can make your own thumbnails. I used to use Paint, but now there is an app that I use, I think it's Thumbnail Maker free version. I create the thumbnail on my phone then email it to myself so I can get it on my PC. I haven't figured out how to add thumbnails using just my phone. Plus, it's easier to type descriptions and stuff on my PC.
