@Un1to1 I do it in a free editing software that I found. I use sounds from the older madness combat episodes or MPN (steam) which you can find on the internet and I also use sounds by Cturix who made sounds for the newer madness combat animations by Krinkles and you can download them here:

I think you do have to credit Cturix when you use them !!!
so basically you export your movie as a SWF, then through Swivel turn it into an mp4, and then you "mix it" with sounds in an editing software. I am not qualified enough to tell you which editing software is the best for you or how you use it, hope I helped at least a little bit :)

Hello, I am also a starting animator and I know how it feels like to not get any advice
Watch this: https://www.youtube.com/watch?v=BFLrgKMujGk
It has a lot of really great information for people starting to animate in the madness style, you'll even find stuff such as exporting and a little bit about adding sounds, it helped me a ton.
I've been playing around with animating for quite some time, so if you need some more basic advice, you can ask and I'll (probably) have an answer :)

It's funny because I have already watched that video plenty of times, but I will say this: How does one add sfx or music to their videos? It doesn't exactly state that in the video itself...
