Enc This tool is able to encode, make a size prediction at a given quantizer and make a compressibility test with (almost) every codec. As input an AviSynth file is required (the file doesn't have to contain "return" or "end" in order to make compressibility test or size prediction). It's structured in a way that make it work with every codec without the need to be modified. You can also put multiple jobs in the joblist and save/restore both settings and joblist. Needs VirtualDub for working (the latest VirtualDubMod version is strictly required if you are going to use size prediction or compressibility test). First time you run this tool, be sure to open the help menu to see the nice people that helped me (i'll never be able to thanks all as i should... but i try :)).
