If daz can output images, I wouldn't be suprised if you could take the image strips and make a movie.
if not, you can do the same thing with blender. you output individual images so that, incase of an issue, your data is not corrupted , you can continue from the last frame saved (can't do that with videos).
Afterwards, go to "video sequence editor" in blender (blender is rather tricky to use if you are not familiar with it, if you need help I can post some images to show you what to do), load in all the images (I think you need to hold both control and shift to select all of the images), and then set your video type, size, stuff, and export.
it does not export webm (I have only seen this as google's server compression, never anywhere else), but it can export AVI, as well as mp4 and what not. Again, if you are having a hard time with blender, I can post a little series of images. I use 2.79, not sure about the 2.8 beta (which is ment to be more user friendly)
