It's a good idea to read through it and try to understand it.

Also, you'll have to figure out what kind of settings you need to attend to when exporting your videos in whatever program you decide on, because this will have a lot to do with how large of a file you end up exporting, and at what level of quality. In general, the higher the quality and resolution, the larger the file. And larger files = longer upload times.

Anyway, you can probably find simple tutorials about this stuff on the web. You're not trying to do anything incredibly complex, so it should be easy enough to get a grasp on the basics so you're not waiting a year for your videos to upload and either get rejected because they're too large, not being comfortable with the quality after it is converted by Youtube, or it being all jacked up because we didn't take Youtube seriously when it told us what not to do.

Good luck.
