Apple iTunes Upsampling Higher Resolution Videos? 201

Posted by Zonk from the technically-that-is-worse-than-nothing dept.
An anonymous reader writes "Engadget has a revealing look at Apple upsampling some of their new 640x480 videos from lower quality 320x240 videos. In fact, their upsampling appears to produce lower quality videos than quickly upsampling yourself with Quicktime. The worst part may be that Apple is charging people to download these new higher resolution videos even if they've already purchased the original, so people are essentially paying for nothing."

    This makes no sense. Apple could use quicktime on all of the videos with ease, or resample. But instead they make the quality worse then if they had used Quicktime. I don't see how Apple wouldn't have used Quicktime in the first place considering they made it. Computer time really isn't an issue for Apple.

      Apple doesn't do the upsampling, their content providers do. Blame Apple for not putting more pressure on them (although Apple are still in the 'beggars cant be choosers' stage here, so they probably cant put any pressure on at all), blame the providers for crappy quality.

        "Apple doesn't do the upsampling, their content providers do."

        Actually, in this case, I believe they are doing the upsampling. Generally, the larger labels really don't care about reencoding what they've already put up there -- they only care about getting the new stuff up there.

        I'm not sure why everyone thought that just because there is a new format, everything was going to be magically resubmitted to Apple.

        At the same time, a good friend of mine just sent a note stating his lable just got word from Apple that at least the audio components of the iTS (I guess its no longer the iTMS) are going to need uploaded in Apple Lossless Format. Does this mean Apple is looking forward to holding the uncompressed files and transmitting compressed or are they going to do the lossless files to the customer? He didn't know because the note said nothing about it.

        Personally, I've never worried about the quality of the videos and all that. The videos are almost always better than I get from my local cable station...whatever that may be. After Battlestar went iTMS last year, I stopped doing the torrent thing and bought them from Apple (I also bought them on DVD, so I was never worried about the torrent stuff...I buy when I have a legal alternative). The iTMS vids were lesser quality than the torrents, *BUT* you never really noticed unless you were either completely anal or had paused a shot. Either way, the content of the show was there and it wasn't like Apple was providing an abridged version of the content. Same with music...as a former professional musician (and by that, I don't mean I've played a few bars) I've never really worried about CD vs. MP3 and I know very few pros that do. I use to get all sorts of promos and prereleases and everything else on CD...now they all send URLs to pick up the MP3s and they are happy with what it is. The last time I got a CD was at a release party and even then it was hinted that since I wasn't a journalist, there were only limited copies available.

        This just goes back to content over 'quality'. Bad pop music with a limited lifespan? Yeah, it better be 100% lossless and the video at HD quality -- I'm going to get sick of it with each passing listen, so it needs to be perfect each time or I'll discard it that much faster. True classics? Well, I just transfered some shitty reel to reel studio outtake from an old blues guitarist that had molded up in someones basement to digital...there are dropouts and songs that just end and a general dampness about the sound that distorts it and makes it sound like its playing through wet cardboard...and its PERFECT. I couldn't imagine listening to this in any other format.

        I guess this is the difference between consumers and creators. Consumers can't add anything to what they buy...creators will fill in the blanks in their head and be satisfied without whinging endlessly about getting ripped off.

        I've ranted too long on this subject...

      Upsampling will not put more information in the picture. It just makes it look better. Possibly Apple is using the same way to upsample the video as you'd do yourself using Quicktime. However, when they have to recompress the video to distribute the upsampled video, there will be another round of quality loss. This is probably what makes the video from Apple look worse than just upsampling yourself.

      I don't understand why they didn't forsee that one day i-pod screens would be larger, so they should keep everything in its native size (the largest SD resolution possible). I work at a mobile content company and we make video ringtones, but we have copies of all are videos at the highest resolution, because we know that one day cell phones and mobile devices will be able to handle the higher resolutions. It prevents us from having to re-edit all those videos. When the time comes, I just run a simple batch and all are videos are ready.

And from the start, all video-capable iPods have been able to decode 640x480 files (and, I believe, output this on their TV adapter), on the condition that they do not exceed a certain bitrate and only use certain compression codec features (e.g., for 640x480 H.264 low-complexity version of baseline profile, 1.5 Mbps or less).

        I disagree. CDs offer some advantages over vinyl, such as track skipping and fewer quality issues such as rumble and warpage. This would be more similar to someone borrowing your vinyl record and converting it to a CD, then selling it back to you.

Incidentally I've had even fewer problems with purchased physical CD's, or better yet, DVD-Audio, but I find there's a level of quality I'll accept to take advantage of certain conveniences over going out to the store and paying $20-$25 for a DVD-Audio disc.

    Now, mind you I'm not defending Apple but I'm saying they're not unique at all in this regard. Obviously if there's a considerably high frequency of upsampled videos, then they've either got a problem they weren't aware of ... or this is simply something they accepted and are willing to deal with it as long as customers are. The solution is to complain to Apple in a constructive way so they have an idea of what customers really want.

    If the majority doesn't care then the majority doesn't care... and Apple will offer products as they see fit. I don't recall anywhere in Apple documentation that they ever stated that products in the 640x480 library were remastered from the source. So, all the energy expended whining here on slashdot about it should be spent sending complaints to Apple so that they get the picture and do what needs to be done to retain their bottom line. If a large enough percentage of consumers call them on this, they will change their practice and require all 640x480 content to be remastered... but don't expect them to be inspecting the contents of every file submitted to them, as the process to verify whether or not the content is upsampled cannot be derived from looking at the metadata... Each file would have to be inspected manually, at length. The end result is that you'd have to wait a hell of a lot longer for new releases and you'd be paying much more for them to make up the difference in labor expenditures.
