Do yourself a favor, learn on a pro software package like Adobe premiere, Vegas pro, Final Cut pro... each of these programs have cheaper dumbed down version, and when you make enough you can buy the full blown versions assuming you want to stay legit.
They have steep learning curves but between all the tutorials on youtube and tutorial sites, shouldn't take long to learn the basics.
The cheaper programs other than those 3 will be easier to learn, but you will develop bad habits as they have non standarized controls and you won't be able to transition to the bigger pro programs in an easy way as those all for the most part have standardized controls.
