What does Frame cadence mean?
Frame cadence is the pattern used to present source frames over time, including repetitions needed to fit a display’s refresh timing. An even cadence can preserve consistent motion, while uneven repetition can introduce visible judder.
Why it matters
It is distinct from the source’s spatial resolution and from network throughput. A film can arrive without data interruptions yet look uneven when its timing does not fit the selected output naturally. Supported frame-rate matching can help, but may trigger a brief display-mode switch. The app and device must both implement the relevant behaviour.
A practical example
A24 fpsfilm fits evenly into a 120Hzrefresh by repeating each frame five times. It does not fit evenly into 60Hzwithout a different repetition pattern or conversion. Increasing the player buffer normally does not change that mathematical relationship between the source timeline and display output.
