Thanks. I’ll try some other builds. I did include the entire command line and
output. I used:
.\ffmpeg.exe
at the command line.
and there was no output, just an immediate crash and a WER popup saying the
ffmpeg.exe had crashed.
I’ve tried same build on my local machine and it works fine.

Hello all,
I use the following command to concat list of videos to one video ‘merged.mp4’:
ffmpeg -y -f concat -safe 0 -i /usr/ramDisk/video_list.txt -c copy -acodec copy
-movflags +faststart /usr/ramDisk/merged.mp4
the content of the ‘video_list.txt’ is something like this:
file '/usr/ramDisk/
Forgot to mention that the original concat command referred to mp4 files with
an audio stream and now the audio is saved to wav files separately.

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:

You can use -x265-params to pass x265 settings. In this case to specify
input-csp i444.
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
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)
