Videos stutter or the screen is slow

Most stuttering comes from the player, its resolution or the network. Work through these.

#The player

• Smart TV browsers are often slow with video. A Fire TV Stick 4K, Raspberry Pi 5 or Windows mini PC is much smoother. See Which player should I use?.
• Older or very cheap sticks struggle with busy designs: many animations, effects and widgets at once. Try simplifying the design, or use a faster player.
• Restart the player (⋯ → Restart player) if it has been running for weeks.

#The resolution

• On a Windows PC, set the display to 1920 × 1080 under Settings → System → Display. Drawing in 4K is four times the work for the graphics chip, and many older computers can only send 4K over HDMI at 30 frames a second, which makes animation look choppy.
• If you do want 4K, use a player and cable that support 4K at 60 Hz (HDMI 2.0 or newer).
• Raspberry Pi and Fire TV players are already set up for 1080p.

#The network

Videos are downloaded before they play, so Wi-Fi doesn't usually cause stuttering, but it can make updates slow to arrive. YouTube videos and web pages stream live, so they do need good internet. For video that must play perfectly, upload the file instead. See YouTube videos and web pages.

#The video file

SignBlink converts uploaded videos to 1080p for smooth playback. Very high frame-rate or unusual videos can still be heavy; exporting at 30 frames a second from your editing app helps.
