My son's Senior recital is tomorrow, and I want to shoot video. I've not really shot any meaningful video with a DSLR before...in the old days, movie/video cameras focused and tracked and you didn't have to worry about it.
I think I've turned on autofocus on the D7100 movie mode...but it focuses like once, and doesn't really seem to be doing any tracking. It shows AF-F (and a face) in the mode on the back, so I suspected it's in face detection, but it looks like a pretty poor excuse for it.
How do you do it!?!?!?!?

| I've been shooting with DSLRs for a while now. I've never had AF available while shooting. The AF systems aren't really optimized for video even if that's one of the selling points. The best thing to do is to set your aperture to something where you don't have to worry about anything being out of focus OR rack focus, which can take some practice. I know you only have a day or less to practice, but once you get the hang of shooting and focusing at the same time, it can create some wonderful video. If you're looking at shooting without a tripod or monopod then it becomes a little more difficult but certainly not impossible. |

Doing such stuff with a DSLR is not easy Neil, even for an expert. But you can do something to make it easier: use a tripod and forget zooming. Use live view and set manually a point of focus on the stage. Cover the entire scene, don't try to follow the single children, the DOF of a DSLR wouldn't help you. Maybe from the screen it could seem to be ok but when you see it on a computer you will realize most of are out of focus. This is the main difference of traditional cameras and DSLRs. If you can, don't use a wide open aperture but it depends on the light conditions. The acceptable ISO value with a D7100 for me is 2000, but mine is probably the eye of a video expert who see noise everywhere. Don't forget to set the white balance before shooting. As for the quality you can choose HD 1280x760 or Full HD 1920x1080. As for the audio recording the microphone is not an incredible stuff but in D600 and D7100 Nikon improved it a lot. If you have any doubt feel free to ask :)

Thanks. I'll try that. Another option I'll have in my back pocket is just to shoot with the RX100. It works great.
But it has a 30 minute limit, and the concert is 45 minutes. So no unattended shooting with that.
Then I just read that the Nikon has a 20 minute limit in high res, 30 minutes in standard res. Argh. What were these guys thinking? |

I believe the reason for the recording limits are to avoid taxes in the EU. Anything beyond X time would be considered a video recorder which is taxed higher or something like that. The RX100 records a beautiful 60p (Or 50p for PAL) video. However, in order to watch it you'll have to drop it from full-HD to standard HD if you put it on a DVD or Blu-ray as I don't believe any players can currently play video at 60p. Your best bet would be to then convert it to 30p. |

Neil there are a couple of reasons for this limitation: first of all sensor is at risk over that time, it can overheat. There's also another 'commercial' limitation, at least in Europe: if the cameras record more than 29 minutes and 59 seconds they become a video recording device and there are specific taxes on those ones.
Neil, you should ask if there is some sort of pause in the concert. I have been working in this sector for a long time now and I used (and sometimes still use) tapes, so I developed every sort of tricks to find out the right moment to change them :)
In any case a stop and re-start can be very fast on a camera. |

Thanks all...
I think it went ok...I just got back home and have only looked at the video on the camera so far. We'll see, and I'll post a link.
The concert was absolutely incredible! He blew us away and so did his accompanist.
