I’m generating a Haldclut using the below code:
ffmpeg -f lavfi -i haldclutsrc=8 -frames:v 1 hald.png
This works well enough, but the cmd line displays a warning informing me that the hald.png pattern is invalid, and does not contain a pattern such as %03d for an image sequence.
It suggests I should use the -update option with –frames:v 1 if I want a single image.
I’m already using this, without issue, and without the -update option, but how do I impliment this option to remove the warning.
