Can an incorrect Aspect Ratio be fixed in Video AI?

I have a video that displays incorrectly, so it was likely incorrectly encoded. Anyway it’s reported to be 1280x720 16:9 but in reality it is 4:3. This makes people and objects look stretched out (fat) horizontally. In NLE’s I can correct this by simply changing the Pixel Aspect ratio from 1.00 to 0.75 or using “Zoom” with unlocked aspect.

Is there a way to correct for the same thing using VideoAI ?

I’ve not found a way to do it in TVAI (this has come up before). MKVToolNix is your best bet for remuxing the video (assuming supported codecs/containers).
