I have since moved on from using my laptop that I used to make everything from, and as such I no longer have windows movie maker. What is another free alternative that allows me to

1. import gif/avi/mp4

2. import mp3 and edit/trim start time (bonus if I can speed it up/slow it down)

3. save as an mp4 file without upgrading to pro









edit: I would also be happy to let other people get in on posting mp4/gifsound stuff from this page. reply or something if you are interested
