Seems the problem was due to mipmaps, thx for the hint :)

All right, problem with changing the upload format is ptanimimg is not
prepared for this (maybe images could define a preferred format for
upload?).
About ffmpeg formats seems in that web there is some that would solve
the problem also, only (small) problem is the version i have of ffmpeg
doesnt yet have the ones i'd like to use :) thx a lot (again) for the
pointer. knowing new ffmpeg has the right formats makes me much easier :)
Greetings!
