Yes. The sws flags are used to control the RGB to YUV conversion. In this
case , full range, and 709 for the matrix conversio
Thank you. This works.
Somewhat related question. Does sws_flags have any effect when
converting to yuvj444p color space using scale? (since no actual
resizing is needed)

Personally, I prefer to explicitly control the RGB=>YUV conversion with -vf
scale or zscale
eg.
ffmpeg -r 24 -loop 1 -i iybW.png -vf
scale=out_color_matrix=bt709:out_range=full,format=yuvj444p -c:v libx265
-c
I am facing a weird issue when encoding images to video in the yuvj444p
format. The colors are off and there are artifacts which look like the
image is enlarged and overlayed on itself. The issue persists if I
extract the frames back from the video. I have providing links to
samples below:
