Part 5. FAQs About Making Video Audio Louder

Why is my video not loud?

The most fundamental reason may be that the video file carries a low audio volume, so you can use a tool to increase the volume. Another situation is that the system volume of your device or player is too low. To solve this problem, you can directly turn up the volume in the system settings.

What volume should videos be?

The current volume average for adapting to internet video should be -12dbFS and -6dbFS, with a maximum of no higher than 0dbFS. You should pay attention to these criteria when adjusting the volume of your video.

What is a safe volume level?

Sounds below 70 dBA are safe. Any sound above 85 dBA has the potential to cause damage to your ears and auditory system. Please be careful to adjust your volume while watching videos and listening to music.

Does increasing volume decrease quality?

When you turn up the volume of the video, the audio quality does not change materially. However, too high a volume may distort the speakers, causing the audio to sound as if it is not clear.

Can MP4 be used as audio?

MP4, also known as MPEG-4 Part 14, is a format that can contain a wide variety of media files, and while it is most often used to store video, it can also be used to store audio, subtitles, images, and more.
