I've had Vdub on the pc all this time and i didn't really know it could work that way though, so thanks to Dave for that first video. First time I tried to import images to it, the images weren't numbered so I didn't know why I could not import a bulk of images. That's why I thought it was useless.

I still need to figure out how to fix the batch rendering errors though and so far I have no idea what those errors mean.
