visual and audio compression is based on the idea that for its intended use the user cannot detect (or will accept) the loss of information
the idea being that "quality" is relative that good enough is just that... "good enough"
once a file format and its compression rate are chosen everything flows downstream
each compression/decompression cycle introduces some loss of data
enough cycles occur and the accumulated loss can degrade the data to the point that it becomes unacceptable
"lossless" formats preserve data integrity but result in greater bulk
with very high speed data transmission facilities the size of the payload isn't the issue it once was
as always it is a choice
