I'm fairly new to DR 12 myself, currently taking a very in-depth online training from Color Grading Central... am not finished yet but it is very thorough and would recommend thus far: http://www.colorgradingcentral.com/davinci-resolve-tutorials/
Thanks to both of you.
Both suggestions are too expansive for me.
I’m not going to become a pro editor, neither a pro color grader, all I need is to do some basic editing, including basic 2 cam editing and some very basic color grading.
Are there any good freeware or low cost training(s) for my humble needs?
You can join Lynda.com for $25 per month. You can join for just one month. They have a free trail. Set time aside and you'll go through the training for $25.
