All about Recording Audio for High Quality Videos
There are a few ways to raise the audio of our video to the professional level, and that's what we're going to tell you right now.
Most cameras, whether DSLR or Digital, do not have a good built-in microphone because the goal is video capture. That way, for you to produce a professional-quality video, our advice is to capture audio through an external microphone.
Here, we can point out 3 types of microphones that will help you in capturing the audio, each of which is more recommended for a specific situation - Boom Microphones, Lapel Microphones, and the Smartphone (believe us!).
Lapel microphone - This is good for being close to the mouth of the speaker, capturing the sound in a more targeted way, and therefore does not take so much noise from the environment. Thus, it manages to gain much in the quality of the audio, as well as in the clarity, but only in cases that the voice of the actor needs to have prominence. This should be close to the source of the sound, about a span, and should never be covered or hidden.
This microphone only has the disadvantage of being a little intrusive, meaning it should be passed through the inside of the clothing, and then fixed near the mouth of who is talking, besides being visible, which in certain situations is not recommendable.
It is suitable for audio recording in interviews, or auditorium programs, or in situations where you have a greater control of the sounds, and time, in order to fix the equipment.
Boom, Directional microphone, or shotgun - If you have some money to invest, and if you want a more targeted capture, and a higher quality than the camera, then this is the ideal microphone for you. They are suitable for any type of production because it is very malleable and can be used by both the stationary, for someone handling them, depending on your need.
With them, you get good recording quality and direction. It will pick up only the sound coming from the direction they are pointed to, as well as eliminate outside interference (not so good for highlighting the actor's voice).
Note that these microphones always require either a stand, or some operator to hold it.
Smartphone - Believe it or not, the microphone in your smartphone can be a big help, especially if you're on a tight budget. The great advantage is to be cheap, but another advantage, which perhaps nobody has ever told you, is that when it is positioned in the right place, it can be used as an excellent microphone. Here, the Galaxy and the Iphone gain points, as they have very good integrated microphones, much better than the microphones already integrated in the camera.
To do this, place your smartphone in a pocket that does not do much interference in the capture and ask someone to direct it to the source of the sound. You can also use an improvised microphone stand. It gives a good result.
Remember that they are omnidirectional, that is, they capture the sound of the whole environment, so it is very important to correctly position it to ensure the quality of your audio.
Regardless of the type of microphone you choose, it needs to be plugged in somewhere to do audio recording, whether it's the camera, or a recorder, or computer.
How do I position the microphone to record audio?
Lapel Microphone - The best place is to fasten it on the shirt (just below the neck). However, be careful that the microphone is not in a position where it is subject to overlying the shirt. When the person moves, it can generate noise by hitting the fabric.
Directional Microphone - Should be positioned just above the actors, and always directed to the mouth. This is because the tendency of the voice is to rise. Take care that it does not appear in the image, disrupting the quality of your video.
Smartphone - The principle to follow is the same as the directional microphone. Connect your native audio player of your phone, place it in the cradle, and position it below the actor, with the microphone pointing to his mouth.
Top Tips for Professional Audio Recording
1 - Tap a palm before you start recording your audio.
It sounds strange, but it is not! When you record with an external microphone, what happens is that the image and audio are separated, and then, to put together, it can become a nightmare so that the image and audio are perfectly compatible.
When you tap a palm before starting your recording, it will generate a peak in the line of your file, which will make it easier to identify where the part that really matters begins.
2 - Always record a test audio.
It is very important that you record a test audio and listen on the computer before moving on to the final recording. In this way, you already know how the final audio will get, and going in time to make some corrections, such as external interferences, proximity to the actors, echo, among others.
3 - Projection of the voice.
You may have the best microphone in the world, but if you do not know how to project your voice, there is nothing the microphone could do for you. So, keep a firm posture, fill your chest with air, and only then start recording. It's important that you relax, unwind, grimace, test your voice, stretch, or anything else that makes you uninhibited in front of the cameras.
