The magic word is: Deepening!
When you have a LD, the first thing you should do (and what I forget quite often and am not good at yet) is deepening to increase vividness and length of the LD. It can be done as tosxyChor suggested by just shouting “Increase vividness!”, or by rubbing your hands to really feel them, or by peering at your hands and dream objects and observing all the details of them quickly but thoroughly. An interesting video for that technique is the following:
Other techniques I heard of are ripping off your clothes (because you get aware of your body sensations) or taking the vividness pill which you will find in your pocket while dreaming
The general idea is to stimulate your senses until you have a vivid dream. Oh, and regarding “video performance”: I have heard that dream vividness can go beyond that what is possible in the real world, but I haven’t seen those HD visuals yet.
