I’d like to ask a question that went unanswered in the other thread dealing with this topic, namely: how to crop and also make the render output dimensions match the cropped image dimensions? When I offset/crop the image in the Strip input panel, there’s still the issue of the final render output being same size as it was before, just with an unrendered area where the image was cropped out. Adjusting the output dimensions distorts the image.
in properties panel, go to strip input, the click crop button

For anyone browsing for unanswered questions they might be able to help with, please note this question remains unaddressed. At the risk of sounding unappreciative in saying so, the previous responder didn’t understand (read) the question.
Perhaps it would help if you gave us more details about what you want to do. Why are you rendering more detail than you use, and then stretching the image? I have experimented with this sort of thing (though, not using VSE), and the loss of image quality is really unacceptable. Aspect-ratio changes are also a problem. Therefore, the only way that I know of to get what you want is to set the original render so that it matches the characteristics of the final.
