I have an emitter that is emitting a liquid, but it is really jaggy, when it collides, it is nice and smooth. What can I do to smooth it out in the pre collision part?

Having only a video to look at it is difficult, if not impossible, to determine what's going on in your simulation so I'm gonna have to give you a simple solution/answer:

upres your sim!

You most likely need to play around with the amount of particles (add more) and lower the voxel size.
