 They are potentially broken only if you handle them improperly (such as
 cuts/edits not along IDR boundaries) and the stream no longer complies
 with specifications.

 If you don't "like" where the position of the cutpoints are , then you
 must re-encode that affected IDR=>IDR section - this is what commercial
 "smart rendering tools" do.
