Seat height: upper handles (if app.) in line with shoulders
Chest pad: both hands should comfortably reach handles at full extension
Back pad should sit at upper back
Footrest: allow for a slight leg bend
The video's machine involves kneeling; you need to stand on W&L's

Seat height:
chest pressed into pad
collarbones at handle height
My recommended progressions for pull-ups: dead hangs, active hangs, scapular pulls, negatives, band-assisted pull-ups, then unassisted pull-ups.
For height, drag a jump-block over to stand on.
Chest pad height:
High enough so the handles are just within reach
5 main form cues:
Handles right below chest, wrists flat
Elbows flare out and back
Ideal layback and forward lean (11 or 1 o'clock)
Don't "end vertical"
Handle pushdown moving forward
Hands high and in-line with the chain
Legs, then hips, then arms
Keep shoulder blades tight
Slight bend in knee
Come forward to 90 degrees (avoid full extension)
Control the movement
These come in 2 different heights!
Keep legs rooted and stable under the thigh pad
Squeeze/retract shoulder blades for the entire movement
Keep reps slow and controlled
Pull bar to collarbones/upper chest
Adjust thigh pad to upper thigh (goal: hinge at the hips)
