I make game videos of a local hockey team that plays in the lower tier league. I've got most of the video equipment sorted, but would like to improve the audio in the videos. Currently I just use the built-in mic on my Canon hf g30 and built-in mics on a few gopros. The 'arena' is small, with corrugated metal sheet walls. It's just big enough to fit a hockey rink and a wooden bleacher on one side. Players bech is opposite to the bleacher. I film from the top of the bleacher and the audio I get is conversations in the crowd people yelling and cussing loudly I would much rather get some sound from the ice. Anyone could give any recommendations on what budget gear could be used to improve audio. Im thinking a shure sm58 peeking over the glass or some kind of wireless omnidirectional mic to get rid of wires people can trip over.
