AVI [EDIT: container] has no standard Aspect Ratio flagging, [I believe some apps have tried to implement such, but most apps would completely ignore those flags].
EDIT: RIFF [which AVI is based upon] allows for custom chunks which could implement some form of Aspect Ratio flagging, but everybody execpt the implementor would likely skip over those chunks as allowed by RIFF.
When cropping frames, sample/pixel aspect ratio does not change at all, whether you want it to or not.
(Resizing can change sample/pixel aspect ratio)
