If u have a mechanics stethoscope, with the engine running, place it on the bearing areas of the a/compressor, alternator, and wp to see if u can pick up the noise. It sounds like a bearing to me but it's hard to tell for sure in the video. Be careful.

I'm voting for timing gears.
And since engine damage can result if the chain slips, I think I would take the WP off, break the oil pan seal, and the rest of it and take the timing cover off to be sure one way or the other.
Not intending to give detail instructions above on getting the cover off.
BTW, valve train noise is a type of whiring noise, not what I'm hearing on the video.

OP, can you make a better, longer sound track.
maybe farther away.
longer, unless you are scared to run it. I don't blame you.

undo nuts holding tork verter to fly wheel.
push back and spin by hand.
if you can get it back enough that it is totally away from fly wheel,
start car and listen.

I don't have an auto, so I haven't had this experience. What goes wrong in a torque converter? I thought there was only one moving part in there, at least from C3 time period. I don't know.

Take a close look at the balancer- I couldn't get the video to run correctly, but just looking at the first frame the front edge of the balancer and the timing pointer look to be nearly the same. It could be the balancer is rubbing on the timing cover.
SInce you have a manual trans, the torque convertor won't be the problem.
Does the sound change when you step on the clutch? Possible t/o bearing?

I had the outer part of a harmonic balancer shift rearward on the rubber and scrape on the front of the oil pan (or whatever it was... many years ago). It made a horrible screeching noise. A true whining noise from the front of an engine could be the sign of gear driven camshaft unless you know you've got chain drive.
