I have been busy on Animoto and made several videos; all of which took about 5 mins each! Here is one I used for my French classes to introduce the new question of 'Où habites-tu?'
Try our slideshow creator at Animoto.
It's great, because it's so short, but if you sign up as an educator, you can get a promo code which will allow you 6 months (or more I think) of pro Animoto, so you can make longer videoclips. Try it out.
