Is there any way to know resized video height and width?

When video is resized in new editor, there is no information about its real size in storage, or any other format which you can get through REST API. Is there any hidden place where real height and width are stored? Is there a way to get them using REST API?

My guess is that your only chance to get this information is by downloading the attachment and reading the dimensions out of the binary. Happy to be proven wrong though!
