Getting Skilled High Quality Sound From Your Camcorder
Interviews and presenters
These days camcorders are used for more than just filming house movies. A large community of amateur videographers now film short clips to put on internet sites reminiscent of ‘Google video’, ‘You Tube’ and their very own personal sites. Some of these are purely for leisure whereas others are for info purposes e.g. local historical past societies interview individuals for their reminiscences of the locality.
The standard of modern camcorders and laptop based editing methods mixed can produce wonderful visual outcomes which are often let down by poor high quality sound. The principle motive for that is that the constructed-in video microphone is usually too far-off from the folks being filmed.
At the time of filming, our ears, eyes and mind work collectively to successfully suppress the reverberation and other undesirable sound sources within the room to allow us to hear what someone is saying, what we hear is totally different to what a microphone ‘hears’.
That is the place exterior microphones are required, the closer a microphone can get to the topic, the quieter different undesirable sounds successfully become.
If at this stage you don’t have any exterior microphones then the most effective recommendation for getting good high quality sound from the inbuilt video microphone is to get your camera as close to your sound supply as attainable i.e. about three ft away, nonetheless you would possibly nonetheless hear some digicam motor noise. In case you are taking videography critically then it’s finest to wear closed-back headphones so that you just solely hear what might be on the audio tracks.
Often camcorders have a inbuilt stereo electret microphone which can either be unplugged from its socket or there are external microphone sockets and some means of switching between them and the in-built video microphones. An A/V socket is often accessible for plugging in an exterior audio mixer.
It might be needed to purchase a ‘stereo plug to 2 mono sockets’ lead with the intention to make full use of the 2 tracks which are accessible on most camcorders.
Presenter
In case your presenter needs to be mobile then it will be finest to buy or hire a radio microphone equipment (be sure you get a package that has a small battery powered receiver - not a big mains powered one), this permits a lapel microphone (normally omni pickup traits) or a plugged in handheld microphone (usually cardioid pickup) to be completely close to the presenter’s mouth. The lapel microphone is normally worn on a tie, go well with lapel or shirt, try to avoid putting it on a shirt collar since this picks up too much sound from the throat, which sounds un-natural.
If the presenter is always static and fairly near the digicam always then an electret ‘line microphone’ could be worn related via an extension lead, which must be framed out of shot.
Presenter and Interviewees
If the presenter is interviewing several people, one individual at a time, then a handheld cabled or radio microphone can be used, this could be a cardioid dynamic or condenser microphone. To avoid missing components of questions and/or answers as a consequence of poor microphone approach, a separate lapel microphone may be worn by the interviewer who then points the hand-held microphone at the interviewees.
If a large group of people are to be interviewed then it could be finest to have a ‘growth operator’ to focus on pointing a hypercardiod microphone on a ‘fishpole’ at the interviewee who’s talking.
Alternatively make use of a sound recordist with an audio mixer with a enough number of microphone inputs and lapel microphones to fade up whoever is talking within the group of interviewees. The presenter’s microphone goes to 1 track and interviewees to the other.
At the modifying stage the related audio monitor will be favoured to get as ‘shut’ a sound as potential, if each tracks are pale up all the time then the sound turns into too ‘open’ and fewer inteligible.
In case you solely have one camcorder then it might be greatest to concentrate your photographs on the interviewees after which after the interview to take some shut-ups of the interviewer asking the questions and possibly an introduction and conclusion plus the ‘noddy’ pictures to assist your edit. A wide shot of the entire group where you can’t see the interviewer or interviewees talking is another helpful shot for editing purposes.
Camcorder technical issues.
The built in microphones and pre-amplifiers on most domestic camcorders might not be adequate for skilled requirements. It is best to use a separate audio mixer and microphones plugged into the A/V enter and switch off any in-built ‘auto’ features and limiters and then set the recording ranges within the camera manually in keeping with the Tone generator in the audio mixer.
Analogue camcorders must set their ranges at -4vu and digital camcorders at 20db below full scale and set the audio sample fee to the very best setting i.e. 48khz.
In case you are utilizing microphones plugged instantly into the camera it is best to manually management their quantity (generally fairly fiddly on home camcorders) or settle for the potential draw back of ‘pumping’ audio for those who elect to make use of the ‘auto’ functions.
Condenser microphones will want a separate energy provide on most camcorders except they're the semi-skilled {and professional} versions, through which case you’ll have to pick phantom energy to be active on each channel.
