What kind of video camera are you using and it's optical zoom range?
I use a Sony Handycam HDR-UX10 with the disc recording set on HD. This model has the higher quality Vario-sonnar lens. Then on that I put a 1.9X doubler on it. All of this is on a tripod.
I deliberately included the part where the shot goes away just to show how difficult it is for a single person to not only make a long range shot but also to get a recording. Lots of times I just cannot get everything done in time.
