If you have some portable field recorder like Zoom H2, H4 or similar, you
can record several inputs inside this device (mics incorporated and some
XLR/combo inputs as well). Or you can do the same but less portable with a
laptop and some interface with so many inputs as you need, and the mics,
cables, stands and stuff needed for this.

Then use some multimedia editor like Cinelerra, Kdenlive, Kino... to synch
audio and video, or even inside Ardour that supports audio and video synch
(I have not use this function but I think it was introduced in Ardour v3,
now v4 is out).

Hope it helps.
