Hi Sasha,
I had a look on your XML. everything seems to be fine, have you tryed to deselect “use size information” just to see if resolve try to conform the original sd clip to fit hd timeline before add the size info (in this case it add a scale on conformed clip and the result is double scaling).
let me know.
