i read it just fine. you seem to lack basic logic. he had to retract the original premise that the camera did not move. i don't know if that was the original statement because from what i see, it's been edited a couple times at least a couple times.
original premise: camera never moved, it's been chopped
new premise: it's been moved but it's still been chopped
that's a retraction. he reversed course on a previous statement.
leaern something new everyday....
An alteration that changes the main point of the original statement is generally referred to as a retraction while an alteration that leaves the main point of a statement intact is usually referred to simply as a correction. Depending on the circumstances, either a retraction or correction is the appropriate remedy.
main point has been altered = retraction
