Page-specific workflow
AB repeat is for exact boundaries
A normal repeat button restarts the whole video. AB repeat gives you two boundaries so a practice section starts and ends at the exact moments you choose.
Precise phrase
A at 0:12.5, B at 0:24.5, speed 0.75x.
Micro correction
Use +/- 0.1s for tight phrase boundaries.
Practice share
Copy a loop URL after the markers are stable.
How it works
Set the loop once, then practice without touching the timeline
Load a YouTube video and play to the first boundary.
Click Set A, play to the second boundary, then click Set B.
Use fine tune controls, speed controls, and sharing once the loop feels correct.
Use cases
Built for repeat practice, not passive replay
A normal repeat button restarts the whole video. AB repeat gives you two boundaries so a practice section starts and ends at the exact moments you choose.
Language timing
Place A before the sentence starts and B after the speaker finishes.
Music practice
Loop a riff or drum fill with enough lead-in for the next repeat.
Movement practice
Repeat the exact choreography count instead of replaying long sections.
A/B markers
Separate controls for start and end points keep the practice range clear.
0.1s adjustments
Nudge boundaries when the section starts between obvious timeline clicks.
Keyboard-ready flow
The layout keeps repeat, speed, and fine tune actions close together.
Tips and internal links
Keep every loop page focused on one job
- If a section starts on a beat, set A slightly before the beat to avoid cutting the attack.
- Use 0.75x first when learning, then move back to 1x.
- Keep a named recent loop for the section you practice every day.
