That is wrong, image2 is for any kind of format that must be stored in
individual files. That includes most image formats; PNG is one of them.

That is also wrong, only parameters that can not be read from the input need
to be specified. PNG fully specify pixel format, resolution, etc. The only
missing information is the frame rate; ffmpeg defaults to 25.
