Displaying 24 fps film at 60 Hz requires uneven frame repetition unless the chain uses another conversion method. Slow camera pans can therefore look uneven without any network pause. A supported frame-rate matching mode or suitable display refresh can improve cadence. Look for a regular uneven rhythm in smooth camera movement while playback time advances normally. That pattern differs from a loading pause. Matching a supported film timing can improve cadence, although the underlying motion still contains only the captured film frames.
Recognize cadence
Regular pan judder differs from random loading stalls. A 24-frame sequence cannot distribute identical repeats across sixty refreshes: some pictures remain on screen longer than others. On a slow lateral pan, this can appear as a repeating hitch even when every decoded frame arrives in time. Check a consistent scene without a spinner or audio dropout. Random freezes, rapidly growing decoder counters or source judder require separate investigation rather than assuming all uneven motion is cadence.
Use supported matching
The app and device must cooperate; not every player switches modes. Read the player's actual frame rate when available, because a title described as film may use 23.976 rather than exactly 24 frames per second. Enable the device's documented frame-rate matching and verify that the application uses it. The television's information panel can confirm the resulting input timing. Do not assume a system preference changed the output just because its switch appears enabled in the settings screen.
Expect a transition
Changing HDMI refresh can briefly blank the display. Allow the display to settle after a refresh change before comparing the same pan. Some HDMI chains briefly lose picture during negotiation, so repeated switching can distract from the motion assessment. Turn motion interpolation off or keep it constant for this test, since it can obscure the cadence difference. If matching causes persistent signal loss, return to a supported stable mode and inspect the connection chain.

An example to work through
A film pan looks uneven at 60 Hz but more regular when the chain outputs a compatible 24 Hz mode. The player timeline continues smoothly in both cases and neither version shows a loading indicator. The improvement concerns how evenly existing film frames are presented, rather than a change in download speed or the creation of new camera frames.
Questions about this topic
Is24fps defective?
No. It is a common film cadence. Its characteristic motion is expected; uneven refresh conversion can add a separate layer of judder.
Will faster broadband fix repetition?
No. A faster connection cannot alter the mathematical relationship between source frames and display refreshes.
