FFMPEG: conversion from YUV (BT601/709) to sRGB

[rgr]

What's the current best way to convert YUV to RGB using ffmpeg?

Is -pix_fmt rgb48 enough(1), or should I still use "-sws_flags spline+accurate_rnd+full_chroma_int" (apparently it's already enabled by default)?

A different filter? Zscale?

It is important that the filter respects the encoding settings, e.g. BT601 limited range or BT709 full range.

(1) "ffmpeg -avisynth_flags +all -i "input.avs" -c:v rawvideo -pix_fmt rgb48 -f nut

Yes, I'm considering it.
By the way, will regular ConvertToRGB48 be any worse?

It shouldn't. Maybe some rounding differences? I don't really know.
