Tips on recording live music, please?

I own a NIkon D5000 and would like to start filming live bands, and while the video quality is radical the sound is awful. I was wondering since the Nikon D5000 has no input for a mic what you guys would suggest me using to record the sound?

You need to plug directly into the soundboard, and then sync the audio and video afterwards.

It's going to be really difficult "filming" with this camera since it doesn't use film. Abusing terms only makes you look dumb. Now you've really done it calling film video - oh my, where does it end.

Getting audio outside the camera isn't difficult, it's the loop that will take the time. Will play back after upload be exact? Who can tell. Will the recorder do it's job? Will the microphone you choose not distort with that kind of volume level.

I'd agree, if you can tap into the band's sound board, take a mike level feed out to your recorder's mike input you might lucky. Then there's the editor and the loop - but that's another story.

As someone stated, you need a direct feed to the mixer panel and also a house mic (one with a strong cardioid pattern). I generally find that mixing the direct feed with the house audio turned down around 6 dB (need to experiment) gives good fidelity plus a bit of ambiance. The direct feed is too sterile sounding. Having a bit of the house audio gives a bit of house reverb and audience reaction. You also need to time-align the direct feed with house audio since there's a slight delay which is annoying if not corrected.

You also need to sync the external audio recording device with your video. Before the gig starts, get someone to clap in to a stage mic (equivalent to a clapper board you see used in movies). This will give a visual and audible means of aligning your audio and video tracks.

The device you are thinking about seems like a good little recorder. You may also consider getting a little Mackie mixer. Makes life much easier trying to balance audio channels. Be sure not to clip your audio. Digital recorders suck when it comes to clipping! Best to have someone deal with the audio while you do the video shooting - at least until you can figure out your audio settings.
