Very hard to sync two videos when the canvas preview lags extremely. I have a i7 processor and 8gb ram so it's probably not my computer. I'll be doing a lot of videos with one video over lapping another and it's going to be very difficult for me to edit them together when I can't view them. One video works fine but when I add the second video into another track it lags and is very choppy. I'm doing drone videos and will need to have two video, one of the camera from the drone and another from my point of view with them sync together.
