The most important thing to consider is a microphone. Most on-cam mics suck, and audio is I would say more important than the quality of the video (that is, even if your video looks awesome, if the audio sucks, the video ultimately sucks). You will want to invest money in a good lapel mic if it will only be the president talking, or a solid handheld mic if you’ll be doing interview style dialog. The next thing is lighting. Wait till youv’e bought the camera, and then do tests to see what lighting conditions you can reproduce with the lights in your office, the locations, etc. Your goal is of course to make the president look great, and lights really are the key to this (well, that and a not busy background… but not a wall, that’s too boring). There are different types of lights out there which produce different effects, I’m not a lighting technician so I can’t help with this sadly. In terms of production time, it really depends on your skills. 30 seconds is pretty short, but the shoot itself will likely take half an hour to an hour to set up, test lights, record many times (that’s the key to all recordings of any type, do multiple takes). There’s not a lot of video cleaning up one can do other than cuts etc, if anything it’s the audio that will need to be cleaned up to take away the breathing between phrases (or reduce it). A 30 second production should be something one person can handle… but putting it onto someone with no actual training is a bit cruel of them to do. Sadly, video quality is somewhat proportional to your budget, so please let us know the exact dollar figure so we can make recommendations appropriate to you.
