Does lossy encoding always produce the same result? 2011-03-05 02:43:02 I read on the forum that if I run the same file through a lossy encoder twice it will produce the same bit identical files. I want to know if this is true. I thought the algorithm decides what to keep and throw out but it differs each time the encoder is run? What about the container it's stored in isn't that going to be different each time too (aka AAC -> M4A) thereby making them non-identical CRC's? What if it's VBR won't that vary each time the encoder is run? Any input is appreciated it's just a curiosity and want to know.
