I came across a suggestion by Philip Greenspun on his personal website about Capturing Family History on Video. This seems to me a fantastic idea, and I'm going to give it a go later in the year hopefully. But I want to ask about recording audio, which I don't really have much of a clue about. I intend to "interview" my own parents as well as several aunts and uncles. The interviews will probably take place in a living room or kitchen in the respective houses. Each interview will be with 1 or 2 people. I have a Sony α7 II, and I'll set it up on a tripod with a 50mm lens probably. But how should I record audio? I will need to buy some hardware for this, and if possible I'd like to keep my expenses under £100. Where do I start? What are my options even? Philip suggests using lapel microphones, but I am wondering if that's really so essential. I don't want my relatives to feel that it is a "professional" interview - I'd like them to relax. I was wondering about one of those directional mics that slot into the camera's hotshoe. Are they good for recording 2 people, or only 1? Do they offer a significant improvement over the camera's built-in mic? I assume so. What about something like the RØDE VideoMic or the RØDE VideoMicro - would either/both be a reasonable/good option? If lapel microphones really are significantly better, what are my options at this kind of budget? Particularly with 2 people. Can I use a simple splitter and input one person's audio to the camera as the left channel, and the other person as the right channel? Is that even a good idea, to have different people on different channels? I probably won't edit the video myself - I was thinking of maybe using an online freelancer to outsource the editing. What about a wireless receiver that can simultaneously connect to 2 transmitters/microphones? Does such a thing exist (at this budget)? Thanks for your insight.
