Hey man…
The final format of the file does not make much of a different in file size. (if thats what your asking here)
Its all how the file is encoded. the codec you use (compression method) is what ultimatly determins how large or small the file will be.
Research the help file of whatever software you are using to know what kind of codecs are available to you
