I would like to know a method that could be used to first, extract frames from

$ ffmpeg -i in.avi -f image2 image%05d.png
and then reconstruct the AVI from these extracted frames.

This is just a very simple example.
Note that it only partially "reconstructs". Sound isn't taken into
consideration, and you're losing all information about frame timing,
which is relevant amongst others for fps, variable frame rates, and
audio sync.
You also need to tune your video codec and its quality. And possibly
the fps...

Thanks Moritz,
I am trying to learn more about the options that might apply to my
problem. I have looked at the "header" information in my AVIs and
perhaps with some experimentation, I will be able to reconstruct a
"close" AVI from the extracted frames.
