What is a “rebuffer?"

A rebuffer (also known as a “stall-out”) occurs when a video stops playing mid-way, pauses to reload buffer data, then resumes.

Experts often discuss a 1% buffer‑time ratio, which might sound low—but in reality, that means about 25% of 30‑second viewers will experience at least one stall.
According to Mux, rebuffering encompasses all stalls during playback, and is measured by frequency, count, and duration.

Across the industry, roughly 25% of all playback experiences include a stall (≈25 out of 100 viewers).
With SmartVideo, that rate drops to under 3%—meaning only about 3 out of 100 viewers stall during playback.

This translates to an 8× improvement in smooth playback experience. 🙌

Better viewer retention: Fewer stalls mean fewer viewers abandoning your video.

Enhanced engagement: Smooth playback keeps viewers watching longer, boosting conversions.

Superior user experience: Reliable performance fosters trust and brand credibility.
