Ahh, I had heard of Audacity. I will check it out tonight, thanks!
Yes, I don't want to spend a lot of money on a video editor, so I think I'll just stick with the free ViewNX 2 from Nikon for now.
For clients all I can really do is make exact copies of images or cut video down to just what's needed. No other editing can or should be done. :)
Oh! I didn't think of that - using the many video editors from camera manufacturers like Sony's PlayMemories Home which is great at organizing and basic editing! Great advice :) If VewNX2 can handle basic video manipulation then that's all that is needed really, in this case.
