You can make this type of videos with Adobe After Effects. If you cant use it fully, you can get premade AE files from Videohive for $10-$30 each. And some of them are all over the warez sites as well. All of them has pdf or video tutorial and can be fully edited (texts,video parts, effects, music, etc) w/o any deep knowledge of the software in 1-3 hours. After that you can render it for yourself in avi, then convert the 1-2GB video to mp4 for 1/100 of the original size, and upload to youtube.
