Can i use a website to add a voice over to a video?

[Sevy]

I created a Video (.mov file) from a Powerpoint and i brought it to my imovie but for some reason when i play it it doesnt show the change in slides, so i cant add a voice over because i dont have the right timings. Is there a website i can upload my video too and do the voice over from there, or is there a solution to my problem?

Firstly, I recommend using VLC Media Player to play your converted video as other programs can sometimes be tricky. Download it here:

Secondly, try converting your video into a format which Windows Movie Maker likes and then add audio using that instead? You'll find it to be a lot easier.
