My other main technique is to count the number of 'gaps' between notes as opposed to thinking in terms of note names.
Re videos above: You need to avoid expanding and contracting your hand unnecessarily since it is just added effort to your playing.
1rep5 easily instructs you to replace the previous position of 5th with the thumb, this kind of thinking can be applied for anything where fingers are replacing the other whether they play the very next note or not.
Why did you use fingers 5321, when your standard arpeggiation of that hand shape is usually 5421.
Sometimes, though, it's worth it to do some extra movement if there is a good reason. In the situation where you have all white keys, like in the octave transition video, it can be hard to follow the feel of the breaks between the white keys when you have to move more than a few keys at a time. The motion I showed in this video does require some extra motion, but I think it can be worth it sometimes if it helps to avoid hitting wrong notes or looking at the keyboard when reading.
