If your network bandwidth is not enough (lesser than media bit-rate), you may experience
frequent “buffering." This “buffering” may result in an animation such as a “spinning wheel”.
This leads to a pattern of stoppping/resuming of video playback. This is called stall. For best
results use Ethernet connectivity or for Wi-Fi use an 802.11ac Router/Access Point.
Stutter and Judder
When the TV refresh rate doesn’t match the video frame rate you may see “jumps” or “hops” in
video at regular intervals typically when the scene has panning motions. This effect is called
judder. This is not random stutter, but a skipping at regular intervals (milliseconds or
seconds). For best results, use TVs with a refresh rate of 60Hz (120Hz or 240Hz).
Random pausing of video is called stutter. Please note this is random and not periodic in nature.
Typically one sees a pause with audio resuming normally, followed by few frames getting
skipped to catch up with audio.
To get the best video experience, modern TVs have an internal algorithm with the capability to
understand the cadence of raw video frames provided from “decode” capable sources. The
term for this varies, depending on the TV manufacturer (like “natural motion smoothening”
etc.). In technical terms it is termed MEMC (Motion Estimation Motion Compensation).
Consider enabling or disabling MEMC setting to see if there is an improvement in performance.
