Why when it's already x265 4K !!!!
Downsizing from x265 4K to x265 1080p doesn't take long.
There has to be a faster way to do this, especially as it's becoming a lot more common place.

The codec used for the source is not the point - the time it takes to decode is muuuuuch smaller then to encode.
So if the source already is h265 makes no difference.
What takes time is the new encoding - the more advanced the codec (x265>X264), the more pixels (4k>1080p) and the higher the encoding settings is what takes up time..
Encoding 4K in x265 really needs a lot of horespower, no matter what the source once was...
