+The file-format is determined by the file-extension that you choose for the output file (.avi, .mov, .flv, .ogv, .webm,...)
+Note: not all combinations of format+codec+settings produce files which are according so spec. e.g. flv files require sample-rates of 22.1kHz or 44.1kHz, mpeg containers can not be used with ac3 audio-codec, etc. If in doubt, use one of the built-in presets
