compression & DVD

Hi all..

Any website documentation that does the software it gives to you is gonna say things like 'legacy' and 'use this better technique ' to do better video conversions of DVD/Blue-ray at a smaller file size, but aren't we all forgetting something.. ?

You can argue file size would be more better if the quality is better, *but* my argument on that is always the same... All you gotta do is turn to CD's and look at the lower frequency they use to make it for on a 650MB disc to know that audio is lost, compared to 48Khz at the recording studios..

Thus, the same would apply to video wouldn't it.. That is, if u'r rather favor smaller file size, how can that be "better"" than a larger size... If the file size is smaller due to better compression, that not the only thing..... there must be info thrown out as well... therefore quality would suffer as a result..

Basically, what people are saying then is "They would rather lower quality and smaller file sizes over DVD/Blue-ray quality" Unless compression has come that far to have half the size *but* exactly the same quality *and* resolution/aspect ratio. Since many conversions done like Handbrake I would guess, must alter the aspect ratio to bring down file size more.. so the result if u end with some different 'anamorphic' resolution different from what the DVD was...

If u'r up-scaling to 1080p from DVD then quality would suffer yes as well? because u'r converting resolution.
