Thanks Micheal! I''ll have to take some time to see what's going on there

Ah! that would explain a lot!
I can confirm I'm still confused, however..
My understanding is that RGB24 has three planes, red then green then blue.
From yo
I do apologise, the example I just posted omitted the planes argument to
lagfun, here's the command I was using and resulting output
ffmpeg -i IMG_1685.MOV -q:v 0 -vcodec h264 -acodec aac -strict -2 -filter:v
format=pix_fmts=rgb24,lagfun=decay=0.999:planes=1 greenlagtest2.mp4

Hi Folks,
I'm exploring the lagfun filter and think I may have some fundamental
misunderstanding as I'm not getting the results I expect.
I have a video of green lasers on glassware in the dark and wish to make the
laser flashes persist.
My attempts so far seem to result in the green flashes
Lagfun looks close to ideal, thanks!
Robin.
