Don't forget the sound

When you start creating a video, also think about the sound. Indeed, the video is composed as much of sound as of image. Without good sound quality, your audience will not watch your video to the end.

Sound can come from different sources in a video: the sound of your recordingof the sound design or just a music. What you choose will depend on the type of video you are going to create but it doesn't matter what you choose, quality will always be a primary criterion.

By thinking ahead about what kind of video you want, you'll be able to Define which sound capture is right for you best and can prepare you to have a qualitative sound.

Yes, the sound in a video is just as important as the image! And even more so for some who consider that constitute 70% of the film. But why is that? And how can you get quality sound? I will answer your questions.

Recording, direct sound capture

Most of the time, the sound is captured during the recording of the video.

First of all, the sound quality goes depend on several factors. And will firstly result from posting requirements.

The noisier the environment in which you are going to film, the more likely it is to be polluted by interference noises. However, this kind of problem can be solved with qualitative material.

Indeed, a second factor that comes into play is going to be the quality of your equipment. In order to record quality sound, you will first need to have adequate recording equipment. If you only film with your mobile phone, the sound recording will be done with the microphone of the latter, so prefer a quiet environment to avoid any sound nuisance. Otherwise, a solution is to buy an external microphone like a tie mike for interviews. Depending on the desired rendering and your type of video, you will have different equipment: omnidirectional microphone, external microphone, camera, external recorder, laptop?

And yes, when your video includes a person speaking, in order to have a good sound, you have to pay attention to the distance between the microphone and the speaker. Prefer a micro talker distance of about 10cm.. If the microphone is placed too far away from the speaker, the speaker's voice will get lost in the surrounding noise and will be harder to hear. Conversely, if the microphone is placed too close, it can be unpleasant to listen to.

If you use a speaker, make sure you get a good speech from him or her so that it is easy to understand when listening. A good sound recording during a speech, allows a good understanding of the words by your audience but also for artificial intelligence. A qualitative sound recording is therefore essential!

If you are picking up sound directly, remember that removing a parasitic noise is complicated to mix. and that it is therefore necessary to focus on a qualitative approach directly.
