Loopstream

Practice the moment, not the whole video. Loopstream adds a focused practice workspace to YouTube. Mark an A and B point, repeat the section, and fine-tune either boundary in 0.1-second steps without scrubbing through the entire video. KEY FEATURES • Create precise A–B loops • Fine-tune start and end points in 0.1-second steps • Adjust playback speed from 0.25× to 4× • Use a 3–2–1 countdown before playback • Discover Predefined Loops from timestamped video descriptions • Preview, fine-tune, and optionally save Predefined Loops to your practice cuts • Save, rename, update, replay, and delete loops • See saved loop positions on a visual timeline • Save videos into folders and mark favorites • Open saved videos directly from your practice library • Control playback with keyboard shortcuts • Choose your preferred interface language directly from the Loopstream side panel HOW TO USE 1. Open a video and launch Loopstream. 2. Choose a Predefined Loop when available, or set the A point where your practice section begins. 3. Set the B point where it ends. 4. Fine-tune the range and playback speed. 5. Save the loop and return to it whenever you practice. Predefined Loops are detected from timestamps provided in the video's description. They are temporary until you choose to save one to your practice cuts. KEYBOARD SHORTCUTS • R — Enable or disable looping • B — Start the 3–2–1 countdown • Space — Play or pause LOCAL STORAGE Saved videos, loops, folders, favorites, and language preferences are stored locally in your browser. Loopstream does not upload your practice library to a Loopstream server and does not download video content.
