Are you going to video the trip all the way up to affixing the label and handing it to the clerk? All while the package never, even partially, leaves the camera's view? Without that there's no trail and no proof of what's actually mailed.
Even with that, it's easy to manipulate, even without camera tricks. Ask any magician.
It's good that you're trying to protect yourself. The way you're going about it and the level of protection you believe it gives you is unrealistic.
IMO....you're wasting your time with all of it.
Video proves nothing.
If a buyer claims it's broken, defective, fake, damaged on arrival, the wrong shade, smells bad, bigger than imagined, smaller than imagined.....you can't prove it's not.
The buyer may have video too.
