I had a similar problem a while ago when trying to play looped MP4 files on some older office desktops. The playback was also smooth in VLC but would lag in other applications, mostly because certain players use hardware acceleration better. What helped me a bit was converting the video to a different format or profile with a lower bitrate, just enough to keep the visual quality decent while easing up on CPU demand. Reducing frame rate from 30 to 24 fps also made a noticeable difference without hurting playback too much.
