YouTube is testing a new experimental feature for Premium subscribers that automatically adjusts video playback speed during viewing. Called Auto Speed, the tool is designed to speed up certain parts of a video dynamically rather than applying one fixed playback rate throughout.
According to YouTube, the feature lets viewers finish videos faster while maintaining comprehension. Instead of manually choosing a setting such as 1.25x or 1.5x speed, Auto Speed changes playback pace automatically depending on the content being shown.
Available as a Premium experiment
The feature is currently being tested as part of YouTube Premium’s experimental tools program. Eligible users can enable it through the “Try experimental new features” section of YouTube Premium settings. Once activated, Auto Speed can be turned on from the playback speed menu while watching supported videos.
YouTube says the tool will only appear on videos where the feature is supported, suggesting that not all uploads are currently compatible with the system. The test is limited to mobile devices and select English-language videos.
More Premium experiment
Auto Speed is being tested alongside another Premium experiment called On-the-go, which offers a simplified viewing interface designed for audio-focused content such as podcasts and talk shows. That feature reduces on-screen distractions and can activate automatically when motion is detected while a user is listening on mobile.
The addition continues YouTube’s pattern of using Premium as a testing ground for new viewing features before deciding whether to expand them more broadly. Previous Premium experiments have included tools like enhanced bitrate playback, Jump Ahead, and other playback controls.
YouTube has not said whether Auto Speed will launch permanently or expand beyond Premium users. The feature remains experimental and is collecting user feedback during the testing period. For now, Premium subscribers can try the tool through April 27 before YouTube determines whether to move forward with a wider release.
