Encode image sequences?

[Selur]

By the way, some image sequence could start from minus (-)
Example:
_-002, _-001, _000, _001, _002

That, I won't support, since I think it's silly. (+ it would require to make copies of all frames to make them compatible with ffmpeg/mencoder/mplayer/avisynth/vapoursynth)
I also will only support positive numbering and not hexadecimal or similar stuff.
