Im going to try and do some testing in 5% increments from photo-jpeg 50% to 100% to see how the decode time changes.Originally Posted by litemover
You will have to do your own testing to determine the subjective factors.
Whether something looks more or less 'grainy' - is a subjective problem.
You will have to determine the point at which something is or is not acceptable for the usage you intend.
My testing of conversion tools seems to indicate that Compressor is a more reliable to way convert between codecs than Cleaner.
Cleaner seems to fuck with things more.
I saw no colour differences between any of the images when i rendered with 68 codec types using Compressor.
