Bonus tips: How loud should your video be

Video loudness should range between -12dbFS and -6dbFS, especially if they are destined for the internet. While this level can go higher up to -1dbFS, it should not exceed 0dbFS as this can create distortion. For example, YouTube uses an algorithm to normalize their videos to the range of -20dbFS to -12dbFS. Mixing with these levels enables your video to translate better after uploading. This ensures your media is not significantly quieter or louder than other content on the platform. If you are creating a video for a specific platform, it's advisable to enquire about their preferred sound level.
