I'm trying to edit a video with some music on it.

I've had a bash with this free Windows job & I can't edit the length of my clips by the 10th of a second, only by great big jumps of a whole second at a time, or even more, by moving the edit bar side to side.



Is this how it's supposed to be?

I'm trying to get the picture to change as each different part of the song kicks in, but it's all over the shop & looks shit.

Does anybody know where I'm going wrong or is the software really this bad?

Any suggestion as to what I should be using (as long as it's free)?
