So, I really have no Idea where to post this, but I thought this may be the sub-topic to post it in. Anyways, I was just fooling around with SV and decided to make a MF Test. Now, I do see the line in the smoke from the flash, but, it wasn't there before I rendered it in Vegas. I'm not sure what happened. Well, please comment on what you think I could improve on. Also, this was filmed on a tripod, and all the movements are done in-program.
