Video Optimization

Playlist slow loading often indicates video files as primary culprit contributing to performance issues. Video files tend to be large and frequently cause playback lagging. Video optimization specifically for screen display can dramatically improve playlist performance. TelemetryOS recommends video checking and resizing before media repository upload for optimal performance.

Video optimization involves several key factors directly impacting file size and playback performance.

Resolution

Video resolution directly affects file size through displayed pixel number, measured in width x height format. Target display resolution understanding helps determine appropriate video dimensions for optimal performance.

Common screen resolutions include 1920 x 1080 pixels (1080p) and 3840 x 2160 pixels (4K). Most effective approach involves video resizing to match screen native resolution. 4K video display on 1920px x 1080px screen creates unnecessary overhead. Content resizing to 1920px width eliminates wasted bandwidth and storage while maintaining visual quality.

Audio

Audio tracks contribute significantly to video file sizes, even when display setup won't utilize them. Audio removal from video files for soundless display substantially reduces file size and improves loading times.

Bitrate

Video bitrate, measured in Mbps (megabits per second), determines information transmission amount each second during playback. Measurement directly impacts final file size. Higher bitrates create larger files. Bitrate adjustment requires advanced technical knowledge. Proper bitrate adjustment technique research becomes important for optimization method exploration.

Keeping Copies Original Videos

Original video copy retention and new resized copy naming based on resolution provides readiness for screen upgrades from 1080p to 4K.
