Every now and then my friend's daughter records some songs. She likes to put them on youtube. In the past I converted a few mp3 to a photo slideshow video for her. I don't remember what I used (probably vlc + avidemux). Now she wants to be able to do it herself.

Can anyone recommend any free software for windows so that she could manage to do it on her own?

AFAIK VLC and Avidemux are available for Windows...do you just want to know if there's something other than those?

Thanks. With the number of people putting slideshow videos with music on youtube, I'd think there must be ONE windows app that would let a computer-shy person do it in a few simple steps. Some kind of youtube slideshow wizard? As much as I like her, I don't have time to teach her how I did it using TWO programs. I'm sure there must be a simpler solution.

I'm going to google it, but perhaps someone here knows of a reliable solution. I don't want to recommend her some dodgy windows software that will also install a lot of rubbish adware on her computer.

I second MrCodes of idea because you are also spreading FOSS.
Try to teach her how to use it and i am sure it cant be that hard.
(Note: I never used Avidemux).

I believe Windows Movie Maker is commonly used.

This is what I was originally going to suggest, but the OP specifically pointed out that he wanted it to be FOSS, and I'm pretty sure WMM is most definitely not FOSS.

Thanks to all,

The idea of spreading FOSS is a noble one, and I try to do it as often as I can. In this case, however, I'm looking for the simplest (from her point of view) solution

If she has XP then she or someone has already paid for WMM and it is a good tool for the job.

Thanks - For the above-mentioned reasons I'll probably have to tell her to do it in WMM
