A rebuffer (also known as a “stall-out”) occurs when a video stops playing mid-way, pauses to reload buffer data, then resumes.
🧪 Measuring rebuffering
Rebuffering can be measured by how often playback stalls and how long those stalls last. A buffer-time ratio alone doesn’t tell you how many viewers experienced a stall.
