I've done a lot of research and looking around for an answer to my problem but can't find any, i apologize in advance if this has been asked before. I bought a mazda a week ago ans when it hits between 1200 and 1800 RPMs it has this intense vibration, it's really noticeable. It does it in park, in drive, in every gear, soon as its in that threshold between 1200 and 1800. If i accelerate out of that it stops. I can make a video later if that'll help diagnose the problem. Any input is much appreciated!

It sounds like a misfire. I am also wondering if you are having catalyst issues, specifically clogging.
The mis-fire reporting is notoriously bad with this car but if it is a noticeable as you say I would think it would report. You could have someone rev the engine to that range while you feel the exhaust output. A mis-fire will give you a puffing feeling.
I look forward to the video of the issue.

The first one is in my yard

And this second one i put it on the road

It actually vibrates up to 2500 but it isn't as heavy once its past 2000

I don't really notice anything. I am sure its foing it but not picked up on camera.
You could check motor mounts to see if they are damaged. I wonder if there was timing work done (new chain or tensioners) and new parts put back a little off (one tooth maybe?)
Did you put a scan tool on it and check for pending codes?
When I bought mine the check engine light was disabled so it didn't have any codes. In reality it had 8 of them.

Yeah i hooked a scanner up, 0 codes. I was thinking it was probably the motor mounts but wanted a second opinion. If you turn the volume up in the video you can hear rattling and its everything in the car rattling because the engine is vibrating lol

Sounds like a busted dogbone mount to me (from your description, haven't seen videos) - the V6 puts some serious strain on it and they're not uncommon to break. Can easily be seen from under the car and they're not terrible to replace so long as you have two jacks
