     11  The above example is highly misleading because `setsar=1:1` is equivalent to `setsar=r=1:max=1`. In this special case it accidentally gives the correct result SAR=1:1, but for example `setsar=2:3` would give the wrong result SAR=2:1.

    1113* When going from BGR (not RGB) to yuv420p the conversion is broken (off-by-one). Use -vf scale=flags=accurate_rnd to fix that.
    1214* yuvjxxxp pixel formats are deprecated. Yet for x265 the workaround was implemented, but not for jpeg2000 and AV1. For those -vf scale=out_range=pc should be used.
