I struggled for a long time to find a tool that would record my screen, or my webcam, or both together and then I came across Screen Cast O Matic. It is a great tool that is just so easy to use.
I suggest that you download it to your computer making it even easier to use.
Signing up is free, and you can record videos up to 15 minutes long which I find is more than adequate for my needs. There is a paid version which lets you record videos longer than 15 minutes and it costs only $15 a year so it is not like it will break your bank.
You can save your videos to your computer or to your Screen Cast O Matic profile. You also have the option to upload it directly to Youtube.
I did some previous training on Youtube which you can check out here:

As mentioned in that training I suggest you save your videos to your computer first and name your video as the keyword you want to rank on Youtube for since this will help your rankings.
I hope you have found this training helpful, if you have any questions please let me know in the comments.
Keep up the awesome job!
Best wishes :) ~Sherry
