Does anybody know what this unit is called? – Hardware (Instruments and Effects) Forum

You can see that the LEDs are in the little chrome holders that are common for DIY (do it yourself) projects. That they are not lined up properly and unlabeled contributes to the DIY likelihood. INODA yields nothing on the web and I can’t see what’s in the letter O/zero / circle in the center.

It appears to me, to be a DIY 500 series module as it appears to be in a 500 series rack. Given that it’s labeled as a compressor, I would guess some 1176 style compressor with switchable ratios, but, that’s a complete guess as the lack of knobs doesn’t inspire anything.

Either post the video, give us some more background, or something. Why do you care what it is? Why should we care about it enough to help you?
