Also, the formats that you have specified, are already compressed formats. Do you mean to say you want to transcode? If you are transcoding videos, there are various other factors on which your output video file size will depend.

Not all compression algorithms are suited for running through map-reduce, since most of the compression algorithms are very much context driven and tree based, so its hard to break them across various map-reduce tasks. LZO compression is however a parallel compression algorithm and has can be run in a map-reduce paradigm. The video compression however are different, and whether they can be achieved via map-reduce is something that will depend on, as to how much parallel compression the specific video compression algorithm supports.
