Quick answer
Jerky travel is usually seized rollers, dry or bent tracks, or spring tension that has drifted. Lubrication fixes some cases; most need garage door repair.
A healthy door moves smoothly from floor to fully open. Shaking, stuttering or juddering means something is fighting it.
Rollers
Flat-spotted or seized rollers stick and release. See rollers guide.
Tracks
Dents, loose brackets or tracks pulled out of plumb. See track repair.
Springs
Tension that has dropped makes the opener strain and jerk — balance test.
Opener drive
A slack chain or worn sprocket causes judder at the start of travel — garage door opener repair.
