A/C compressor makes noise

Unfortunately I don't have a yahoo account my friend. Video link immediately asks for login. You could run the compressor BRIEFLY with no charge since there is always oil in the compressor . But what will that determine ? If the noise goes away .... Ok ..there is no gas load on the compressor so that proves not much .. If it remains, you're at the same point in diagnosis .
You could try this if you are so inclined .. Fully charged AC on at idle with noise present ... Quickly restrict discharge hose with large duckbills or soft jaw vise grips ( careful I mean quickly ) if noise really amps up or changes pitch dude it's your compressor ( I cannot stress quickly enough ) noise increase it will be immediate .
You can also try recovering a half pound of refrigerant and use hot water to heat charge can of 134a then charge system while listening for noise at different Rpms... If noise is not present during charge you can almost be sure it's a starvation problem ( EPR ,txv, restriction) but your gauges do not indicate that at all and they will ,definitely . And u would not have 45 degree vent temp not even close.
Did u find screen ? Any metal or black powdery clumps of soot ( Black Death) . The drier also is a filter and would be the likely place for debris to accumulate since it's on discharge side .

Restrictions also almost always show up on gauges but I have seen on modern systems cases where pressures are not far off due to location of guage ports in which case infrared temp gun can find considerable temp differences on high side . They are usually extreme at the exact point of restrictions since that restriction acts like another expansion valve without temp modulation .
