That is just not true. Basic principle: THE COMPETENT USER IS RIGHT. If someone knows BT601, and knowing it decide to produce a video that does not conform to it, for example writing "testsrc=s=720x576,setsar=64/45", then the software must comply. There is a very simple way of flagging content that is supposed to comply with BT601: the SAR is 512/351. If SAR is 64/45, that means someone before nvenc decided that the video is not expected to conform with BT601, and nvenc has no right to decide otherwise. Regards, -- Nicolas George
