Torso, hip, and shoulder angles
Read them as numbers rather than eyeballing a photo.
Posture analysis
Posture claims are only worth the re-measurement.
A single posture photo proves very little — lighting, stance, and the moment you pressed the shutter all move the result. Measuring from video, the same way twice, is what turns it into something you can actually judge.

Numbers you can compare against your own clips.
Front, side, or rear
Different views expose different asymmetries; the rear view is where side-to-side differences show up.
A comparable baseline
Save it and repeat the same setup later to see whether anything moved.
How you film it decides what the numbers mean.
Keep the camera level, square to the person, and far enough back that the whole body fits with room to spare. Note where you put the camera so you can repeat it.
Estimates from a single camera are comparable when the setup is comparable. Note where you put the camera so the next clip can be shot the same way.
Straight answers, including the limits.
Can it diagnose a postural problem?
No. It reports measurements. Diagnosis belongs to a clinician, and these numbers are useful to bring to one, not to replace them.
Why does repeating the setup matter?
Because camera position changes the measured angle. A difference between two clips shot differently tells you about the cameras, not the person.
Does it work from a photo?
Video is better because you can pick the frame. If you only have a still, record a short clip and screenshot the exact frame you want.
Other things you can measure this way.
Record one clip and see what it gives you.
