Aspect Ratio Corrector

The aspect ratio correction button does nothing when I click on it.

Would you be able to do a screen recording? 

The aspect ratio correction is not functioning properly!

What do you mean by "the autocorrector feature"? 

The auto corrector feature doesn't work, I want to correct the stretched 4:3 to 16:9 back to 4:3 similar to what MPC-HC or PotPlayer does. (Like playing old video games on modern systems that the game only supports 4:3 format, but changing the resolution to 1080p (Stretching it to 16:9) and correcting it to 4:3!)

I am currently using AME version 25.0 (Build 54).

We already have that in comparison view in our Beta release. Please review our Trim feature. I don't believe we can fully automate the aspect ratio correction as it involves a user decision on what to do if the format is not matching.

I want to scale incorrectly scaled 4:3 back to 4:3 AR.

How do you envision that to work in AME? Do you want to force scale the output in AME to conform to a desired ratio? And also: we already have the implicit ratio with the selected output video size.
