Hi!
Yes, I was confused and didn't realize that ffmpeg can do all this :)
because I first made a python script that creates star trails videos and
they are copied when processing the next step.
But for normal video, i use
ffmpeg -i /mnt/ramdisk3g/workdir/%d.jpg -r 16 -vcodec mpeg4 -qsale 1 -y
-filter:v "framestep=1,setpts=1.0*PTS" /mnt/ramdisk/mp4/
So I left the image multiplying step (from the python side) and Now there
is now only 1 of each image in the workdir. Dropped out tblend because it
makes image blur or something.

I'm going to use the above to finish star trails videos later too.
You can also use the zoompan filter for duplicating the frames and then
the framerate filter for crossfading between successive frames. I've
described that in chapter 2.3 in my book:
