Problem with tonearm on some lps

Hello everyone! I'm new to this word and I'm struggling with a problem about my tonearm.
On some vynil I've experienced a sort of wobble (I have posted a video on YouTube to show you better).
Maybe it's the lp to be warped? So strange..

Since the camera isn't all that steady it’s hard to tell. I would guess there is a defect on the LP or the location of the spindle hole.

Thank you. It seems to jump and in the meantime I can see a bad sound like ssshhh as you can hear in the video.
It's a not smooth at all micro jump..
 
Have you tried another LP as suggested? Does it do this on every LP? If so it may be the bearings on the tonearm. Does it have any play at all?
 
What MRL said , have you tried another LP? Or is it only on that one album? Does it do it on the other side of that LP? If not then it’s the record , if it does that on every record then as suggested I’d check the bearing in that arm. One other thing , is your VTF correct?

Need to place your camera on a steady stand. Hard to tell with all the movement going on.

If you look though despite the shaky hands you can see how the cart is jumping, now whether that’s a warp or related to something else is to be determined.

Looks like the center hole is off center, this is a common issue. Could also be a defective pressing, and I don't have many newer LPs that aren't a little warped. My Mom's old ones are all dead flat, post 1970 they almost always have a little wave to them.
 
ok, you're new, do you have anything to clean the stylus?

barring that, are you sure your cartridge alignment is correct, along with vertical tracking force?

Have you checked the resonance frequency of your setup? I use a test record which has a resonance frequency track (like Shure IV Obstacle Course record). Your setup have have a resonance frequency too high (close to 20Hz) and is resonating, due to the music.

This.



That cantilever is moving way way more than I like.

Tonearm and cart seem unhappy together. Higher mass arm and high compliance stylus?

Tonearm bearings sticky is also possible.

What's the table /arm?
