Video on dA is still growing. Technical support is getting better - I see 1080p is now supported, although it seems the 200MB limit is still there. Getting 'video submission rights' is still a bit of a mission though. Much of the work is various forms of animation, and some of it is really good. Narrative, documentary and just moving images recorded and edited because they are pretty are in a relative minority, but there are some lovely pieces.
For your edification, some of my favourites. For the best effect, make sure you are in a place where you can listen to the sound, preferably with reasonable speakers or headphones, as sound is as critical a part of the experience as the images. And to have enough time to watch to the end. Unlike images which can be assessed at a glance, also allow enough time to watch them. They are not long, but I have enjoyed them.
