Meh, wife has gone out with her mom and I'm stuck home because I'm not feeling well. I'm bored and have nothing else to do....hold on to your hat...

So, you can use something like adobe audition to try and maybe EQ to try and remove the wind noise in post-production(though, not if it's a live/news anchor type broadcast [more on this, later] because the audio is going straight out with the video and there isn't really any "post"). Really though, the best way is to try and get it right the first time, and there are a few different ways of doing this - depending on the situation....

Microphones

There are two main types of microphones - condenser mics and dynamic mics. You can read more about their pros, cons and differences here

Shotgun Condenser Mic

The first way is with what's called a shotgun mic, these are easily recognisable from their long, thin shape. The one pictured here is the very popular NTG-2.

The basic idea of these mics are that they record only what is directly in front of them, and very little else. These are what you would stereotypically see mounted on high end "camcorders" from the 80s or 90s like this

These are also the types of mics you sometimes see poking into shot above scenes in TV shows if you watch closely and are usually the type of mic you see the "soundman" carrying you can see an example of this, here (complete with deadcat no less). These types of mics are used becuase they are highly directional and good at eliminating background noise from things like an audience laughing, or traffic in the street etc. This works by having the actual microphone capsule at the end of a very long tube with holes down the side of the tube. The air interference through these holes cancels out any off-axis(anything the mic isn't actually pointing at) sound.(more on this here).

I've also seen a shotgun mic used for field reporting hand-held a few times for the reasons outlined above. Though, I wouldn't recommend this without a shock mount because they are usually condenser mics and are therefore very sensitive.

Hand Held Dynamic Mic

The next way I guess would be a hand-held mic of some sort. These are usually the type of mic you'd see reporters holding and can be easily recognised because of the short, fat bobble at the top (the stereotypical "microphone" look). Most of these are Dynamic Microphones (though not all) because dynamic microphones have what's called a "cardiod pickup pattern"

Lavalier Mic

These types of mics are the kind you see as a little black spot clipped to someone's shirt collar. These are sometimes used for live reporting, but more often used in a studio setting for panel shows, news anchors etc.

I don't work in the broadcast industry so I can't say for sure what the reasoning for this, but my suspicion is that these are used in situations where you don't want the mic to be visible, or where performers might need to move about - for example on [whose line is it anyway?]
(http://media.cwtv.com/cwtv/digital-smiths/thumbs/2013/08/05/WhoseLineIsItAnyway-112-Wilson-Bethel_bp-fix_a75e7362_CWtv_720x400.jpg)), or on news anchors. Whereas, in live news settings they actually use the mic with a custom mic flag to advertise the news station.

Digital Recorder

This is one I've not seen used very often, but you do sometimes see reporters in huge crowds round a celebrity holding little boxes asking for comment whilst shoving those boxes in their face.. See here. I can't say for sure what kind of digital recorders those are, but I'm pretty sure that's what they are.

Audio Capture

As far as audio capture goes, there are a few different options here too...

Live

In a live setting, the audio just goes into a mixing board and then out to the viewers or listeners.

Off Camera Field Recorder

Sometimes, the audio can go via a cable(Wireless mics do exist also - so, not always) from the mic into an field recorder this is the one that I have where it is recorder on to an SD card for later editing.

On Camera Field Recorder

Another way is the macro recorder that just clips into the microphone's mic cable socket. This is the Tascam DR-10X that works in a very similar way to the off-camera recorder, but without a wire between the mic and the recorder. News agencies LOOOOOVE these for some reason, I've seen them used a lot. Sometimes you can see a small lump on the end of the mic - it's often a clip on recorder like that....don't be fooled though - Sennheiser make something that looks very similar but is actually a wireless transmitter for the mic, there would then be a wireless receiver going into the sound board to be mixed before broadcast. These are popular when reporting in places that you might not want to lug lots of cabling or a mic boom to. You can leave all your audio equipment somewhere safe in the back of a van say, and just take the camera and microphone with you.

USB Connection

So I don't think I've ever seen one of these used, but it does deserve an honourable mention because it's an awesome piece of kit if you want to be able to use professional mics with your computer easily. That is the Shure X2U. It can turn any mic with a standard XLR connection into a USB mic. It can even provide 48v phantom power to power condenser microphones. I have one and I use it with my AT-2020


I find it makes watching the news more interesting when I start to notice these sorts of things like the kinds of mic they're using and how they're being used...Hope all that makes sense - I'm happy to answer any follow up questions you have...

For business videos, audio quality is most important. What mic do you use in the H5?

I'd highly recommend a good mic and mount. This Rode NTG4+ or similar shotgun mic and a good shock mount like this.

Trust me, perceived quality skyrockets when you have good audio quality. Everybody appreciates good audio quality, while few notice good videography. This will help your customers feel they are getting high quality videos.
