Re: Re-encoded digital video

My hearing is fine, I just don't think spoken word videos require LPCM. Besides, I don't want to spend any money on a better standalone right now, between my 3 week trip to Australia, a new driveway, my son's college and our family cruise around the Greek Isles later this year...I'm hurtin' bro! If you don't like them don't download them. But many people do. Thank you for entertaining us during these trying times (HC down). You have helped many of us through HC withdrawl anguish.

H.264 is not truly lossless, no matter what bit rate you choose [technically no digi video is lossless, but thats a whole nother discussion i have no interest in arguing]...sure there's lossless compression thats been created, HuffYUV and what not, but they're just fringe codecs really...the film industry, which dictates standards/norms, has shown little or no interest in using them

i'll also note, the accuracy of the info in that link isn't exactly spot on...hell, they have ATRAC listed as "Advanced Lossless" audio

Probably because Wikipedia is only fact-checked by insomniacs and the chronically underemployed.

Re: Re-encoded digital video

Not really.

"It's ironic that you put ketchup on your hamburgers, but not filet mignon."

"It's ironic that you toss that cheap Mexican Strat in the back of your pickup with no case, but you don't do the same with your '59 Les Paul."

"It's ironic that you'll watch Star Trek reruns on that 12" black & white TV, but you won't watch Lawrence of Arabia on it."

etc.

cause it is. ATRAC Advanced Lossess is... lossless.
i enjoy wiki for a broad overview, but when I wish to learn more Ill search.
technobabble is often giving wiki a run for its money on mis-information

i have the feeling no one is reading the technical White Papers so sad.

Re: Re-encoded digital video

i stand corrected, i read it as ATRAC being described as an advanced form of lossless compression...not their new-est(?) codec...looks like the wolf pwns me again

but i still stand by my statement that i've personally seen no evidence of the film/video world switching to a lossless form of compression, especially not in the near future...wish it were so, but doubtful imo
