I always video my show (using a point & shoot camera) before it gets dark. Our eyes are better at seeing in the dark than any camera. So to get an idea when, stand outside with sunglasses on and when it starts to get dark then try videoing. Try multi times to figure out your best video time (note: time of day for any future videoing)
Some pointers:
1 - Use a tripod (or sit camera on something solid - ladder, table, trash can, etc)
2 - turn off auto focus and use manual focus if possible
3 - set white balance (use incandescent or fluorescent ) depending on your type of lights
4 - turn on wind noise reduction (usually in video/movie setting)
5 - if using #1 then turn off any vibration reduction
Hope that helps some
