I must admit that I was somewhat 'sniffy' about ambient videos until I came across a posting on a forum where people listed their favourite ambient tracks and pretty much everyone posted a youtube video link - either of a video someone had made of an existing track or the artists 'official' video.
This made me re-think about making some videos as 'ambient eye-candy' for my material (I'm always looking at ways to get my work out there). So I did some research and found Sony Vegas to be a very good tool for creating videos. Years ago I used to make animations for installations / projections in a program called 'Swish' (cut-down version of Flash), but that never really worked as I would have liked, but Vegas does the job indeed.
I've posted some initial pretty rudimentary videos on my Youtube channel, but now I'm now starting to make them a bit more interesting (hopefully), I recently made one from Kati Astraeir's images that were used in the 'ION' artwork. I'm at a bit of a lull regarding working on my next album, so I'II be working on this side-project for a while.
I've now noticed quite a few ambient artists have been making videos for some time.
