Right arch pain, can you see a possible reason in this video?

Do you see a possible reason for right foot pain? There is something not kosher to be seen. It doesnt mean it is valid, or the cause, or that it is primary or secondary, but it should be something that cues up a clinical exam focus to rule in/rule out.

the right hallux does not fully extend. And we know that hallux dorisflexion at the 1st MTP joint engages the windlass, and helps to plantarflex the 1st MET and raise the arch and prepare the foot for loading and for forefoot transition. If the hallux doesn't extend sufficiently (like in a hallux rigidus, painful turf toe etc) then we can have some loading issues. Just something to think about. In this case, it was the cause and answer. But might not always be such.
