I am looking at creating a series of training videos for clients which need to be a combination of screenshots and face to camera. Wanted to know the best combination of tools would get these created with the easiest learning curve and lowest cost. Need them to be good quality but no need to be premium quality. Can I just use my I phone to shoot the video and camtasia to create screenshots. Any suggestions or if you could point me to some resources to research this better would be greatly appreciated.
