A planning estimate from your inputs. Measure the visible response in your actual client.
How it works
Add your estimated model delay, one-way transport time, playback buffer and decode/display delay. This planning budget uses inputs you supply; the result is an estimate. Control acknowledgements and generation-window boundaries can add delay that needs separate measurement.
- Enter estimates for generation and one-way network delay.
- Specify buffered frames, playback FPS and decoding/display time.
- Use the component breakdown to choose what to measure and reduce first.
Common questions
- How do I calculate a video latency budget?
- Add generation delay, one-way transport delay, buffering and decode/display time. Measure the end-to-end visible result separately to confirm the estimate.
- Can I use ping as the one-way transport delay?
- Ping reports round-trip time. Half of it is only an approximation of one-way latency and depends on route symmetry and other conditions.
