Video playback performance in Lightroom Classic is choppy, stuttering, skipping, fails to playback
Video playback performance in Lightroom Classic CC is generally bad and usually degrades after attempting to playback a few videos. Playback is typically choppy, even with relatively lightweight HD files, and especially with UHD or 4K+ content. The video will often stutter when playing, sometimes skipping large sections of video, or playing at a low frame rate and other times completely failing to playback the visuals all while the audio finishes playing. Video in Lightroom Classic usually also appears very low quality when attemting to playback, usually playing at lower resolution with lots of jaggies / aliasing.
Lightroom Classic has advertised a lot of useful video tools (see: https://helpx.adobe.com/lightroom-classic/help/video-lightroom.html) that are nearly impossible to use properly due to its inability to playback video properly.
