Thank you (once again) for your very valuable information!

To give an example - some time ago I downloaded this
https://youtu.be/NOIbJFCa2xk
Although with better quality.
Size was 19kB, 75% of it the "video stream".
Although the frames are identical, YT uses 25fps.

For this special case (only 1 frame)
there was no need for vfr, as I can reduce the constant
frame rate of the one and only frame to the complete length.
I did that with VD's filter "remove frames" (from shekh himself).

And actually I ran into the seek problem.
It doesn't play at all if I remove all but one frame.
there have to be about 20 frames left.

For the general case there remains the question to me
how the workflow will be when there are few different frames
at arbitrary positions (not only one as above).

I will use one of avisynth's dedupe filters then.
They will generate a timecode file ok.
After removing the dupes from the movie
it will have the same lenght but with adjusted constant fps
so it has still the same lenght as the audio?
And after saving that I use the timecode file to
make it vfr, right?
