background

What is mastering?

Mastering is the task of adjusting the sound. By mastering, it makes it easier to hear, and powerful. Simply put, it makes a good sound. By realizing dynamic range, frequency characteristics, sound pressure (loudness) etc, realize it.

For music, professional, amateur, regardless of releasing the song, almost always, mastering is done. For movies, I think that mastering is probably done on commercially available movies and TV programs, but I think that many videos uploaded to YouTube are not mastered. When you listen to the sound of a TV or movie and the sound of YouTube, especially when you listen to the sound of YouTube, it is difficult to listen by the volume difference between the videos (especially difficult to listen to) Saya, time to adjust the volume), there is a difference.

For movies, the word mixing, mixing, MA may be more popular than mastering. What is the difference between these and mastering?

Simply put, it is an image that contains silence, mix and mastering in the MA. Recording -> MA (sound -> mix -> mastering) -> distribution. Since there is a possibility that opinions may differ more than any other person, I do not get deeply involved. ※ In music, the boundary between mix and mastering is ambiguous.

An era where you can shoot, edit, and upload videos with your smartphone

Already there are many useful video editing applications on the App Store. Combining these applications makes it easy to shoot, edit and upload movies with smartphones.

Furthermore, if you combine AI Mastering, you can also automatically master video and audio. You can expect to be able to create movies that make it easier to listen to sounds than ever.

* AI Mastering is an automatic mastering web service that has been provided for composers before. Since full-fledged mastering is possible than the smartphone version, if you are interested also, please do.

AI Mastering Features of the smartphone version

Mastering automatically according to the input sound source.

How to use is over.

How to use

Use as preprocessing (sound) of video editing

It is a method of using AI Mastering as the original material before video editing.

I think that when you record with iPhone's standard microphone, noise often comes in. Noise can be reduced by passing AI Mastering before video editing. Since the volume is also aligned, it will be easier to handle as a material for movie editing.

Use as a finishing (mastering) after video editing

Using AI Mastering as a finishing before uploading after attaching BGM or sound effect in movie editing.

Overall quality can be raised.

FAQ

What is Loudness Normalization?

Loudness normalization is a function to make the volume of video constant. Since the volume difference between videos is reduced, you do not have to adjust the volume each time the user switches the video.

Loudness normalization is also introduced on YouTube. However, if the volume of the original movie is too small on YouTube, the volume after loudness normalization will remain small. Such videos are also frequent on top YouTuber videos.

With AI Mastering, optimize the volume when playing on YouTube so that it does not become smaller compared to other videos. You can prevent your video from losing power compared to other videos on YouTube.

Loudness normalization has already been introduced on YouTube. Is there any meaning to increase sound pressure now?

It is necessary to ensure the minimum sound pressure according to the level of the loudness normalization, but there is no need to pursue further sound pressure.

However, as a result of analyzing YouTube's video sound, there are not many videos on YouTube that have reached the minimum sound pressure. Easily securing the minimum sound pressure with AI Mastering makes it sound comparable to the surrounding sound. ※ The results of the survey will be reported separately.

Since sound pressure and sound quality are in a tradeoff, it is best to aim at the very close sound pressure at which volume reduction by loudness normalization occurs. Therefore, the sound pressure setting of the smartphone version of AI Mastering is set lower than the web service version.

Using AI Mastering, you can raise the sound pressure without thinking about tradeoffs with sound quality at minimum sound pressure.

Does the volume rise so much that the sound breaks?

AI Mastering has a mechanism to prevent sound cracking called a limiter. The limiter of AI Mastering raises the volume while checking whether the sound is broken, so it may occasionally crack sound, but in most cases it will not sound crack.

However, please note that there may be a sound crack due to re-encoding. Re-encoding is to decode a video encoded in mp4 format etc. once and encode again. As a result, the form of the speech waveform changes and the peak jumps out, which may distort the sound.

Re-encoding is done when editing video or uploading to a video site. AI Mastering gives some margin to the peak in order to prevent sound cracking due to re-encoding, but how much peak will pop out by re-encoding greatly depends on re-encoding settings and the original sound source.

If you break the sound after uploading the movie, if you tell us the site you uploaded (YouTube etc.), we will respond.

What is the difference with other video editing applications?

The difference between AI Mastering and other video editing applications is where AI Mastering specializes in sound. Because I can not edit video instead of specializing in sound, I think that it is good to use it together with other video editing application.

It is a comparison table with movie editing application that can be used on iPhone.

It is also possible to download videos uploaded with the application version from the web service version.
