So I'm starting to get into Kdenlive, and finally start to navigate through it. I'm making a small video about 4 minutes in length, with music and currently 5 video tracks, with a few composite, and pan & zoom effects, along with high quality pictures. The problem is seeing as I'm no where near done, I like looking at the rendered video to see how the final product would look, and any rendering "glithches" that would get in the way; the rendered video only contains a small fraction of the whole video (about 18 seconds). I've tried rendering in a variety of formats, all in 1080p 60 FPS. Can someone tell me if I'm doing something wrong, or if this is a known bug. Please I'm planning to put quite a bit of time into this, and would like to run this program smoothly.
Ubuntu Version 12.04
