Adobe makes Premier - one of the best semi-pro NLE editing suites out there. Unfortunately, it is neither cheap or easy to learn.
Much as it pains me to say it, Windows Movie Maker is probably your best bet (assuming you're using Windows). It's free, easy, and it will do everything you want to do. Here's a fairly complete tutorial on using it:
YouTube - Movie Maker Video Editing Tutorial
The software is only half the issue though. If you want to make a good video, you have to
shoot good video. That means proper lighting, camera placement, and sound recording. These factors are almost always ignored by youtubers, and the lack of production effort shows. You should have two or more lights pointed directly at you to avoid shadows. The camera should be on a tripod and
manually focused on your position (if possible). Most cameras have a crummy built-in mic. Consider investing in a decent lavalier mic to clip to your shirt. Failing that, at least run a background noise cancellation filter on your footage after editing to kill mic and room noise. You can do this with free software like
Audacity. While you're at it, check the levels and raise or lower them to get them in the proper range.
Choose your backdrop carefully. As much as we like to see your kitchen in the background, it is a bit distracting and unprofessional. Don't hold stuff up to the camera like you did in the provape review. The camera has to refocus, and that looks sloppy. Instead, shoot closeups of the items you want to show separately and edit those clips into the video later. Script your reviews before you shoot them. You don't have to read from the script verbatim, but try to practice it ahead of time so you know what you want to say and can avoid the "ahs" and "ums". You don't have to look directly into the camera all the time, but you should make eye contact as much as possible.
You should always be as energetic as you can - whether you did or didn't like the product in question, it should be obvious from your facial and verbal expressions (you just seemed nervous and bored in the provape review). And most importantly, don't say in ten words what you
can say in five. Keep it short, and don't repeat anything except perhaps in a final "in conclusion" statement. Just because youtube has a 10min limit, don't feel you have to fill it. You can do a thorough review in 3 min that will have a lot more impact than an 8 min review that says the same things, only slower. The first 20 sec is the most important part of the review, because that's all most viewers will watch. The more engaging you are in the opening segment, the higher the chance that a viewer will keep watching. Keep your title sequence to under 4 sec. and get right to the good stuff.
I did some part-time radio and TV production work a while back, so if you have any specific questions, just ask.
