Hello. I've been having difficulties. One of them was getting these black boxes out of the edited video. This was fixed by using the same rendering resolution as my original video resolution. However, I am having issues with the end result now. The video is even worse quality than when I originaly recorded it. Someone told me to up the bit rate by moving the two sliders (drop down menus) for the bit rate in render settings. This did absolutely nothing. I'm not quite sure what to do next as I'm not computer savy. Any help would be much appreciated.
