what is Volume / Normalized
in Youtube video
In YouTube videos, "Volume / Normalized" refers to the way YouTube processes and presents the audio levels of your video. Here's a breakdown of what these terms mean:
Volume
The "Volume" percentage indicates the relative loudness of your video as uploaded. This value shows how close the audio level is to YouTube's target loudness. A volume of 100% means the audio level is at the standard target, while a volume lower or higher than 100% indicates that the audio level is below or above the target, respectively.
Normalized
The "Normalized" percentage indicates how much YouTube has adjusted the audio level to meet its loudness standard. YouTube uses a process called "normalization" to ensure that all videos have a consistent audio level, providing a better listening experience for users. This normalization process adjusts the loudness of your video to meet YouTube's target loudness, which is typically around -14 LUFS (Loudness Units Full Scale).
Content Loudness
The content loudness value (e.g., -13.4dB) indicates how much the loudness of your video's audio differs from YouTube's target loudness. A negative value means your video is quieter than the target, and a positive value means it is louder.
Example Interpretation
Given your example:
Volume: 100%: Your video's audio is at the target loudness level set by YouTube when you uploaded it.
Normalized: 100%: No additional normalization was needed because your video's audio already met YouTube's loudness standard.
Content Loudness: -13.4dB: The loudness of your video is -13.4 dB relative to YouTube's target loudness of -14 LUFS. This means your video is slightly quieter than the target, but within an acceptable range.
How to Fix Loudness Issues
If your content loudness is significantly off from the target, you might want to adjust your audio levels before uploading. Here’s how:
Check and Adjust Audio Levels in Editing Software:
Use audio editing software like Audacity, Adobe Audition, or the audio tools in your video editing software (e.g., Premiere Pro, Final Cut Pro).
Aim to normalize your audio to around -14 LUFS.
Use YouTube's Audio Library:
If you’re using background music or sound effects, consider using YouTube’s audio library, which offers pre-normalized audio tracks.
Re-upload Video:
After adjusting the audio levels, re-upload your video to YouTube and check the new Volume / Normalized values.
By ensuring your audio levels are close to YouTube’s target loudness before uploading, you can avoid significant normalization and maintain better control over how your audio sounds on the platform.
