MPEG Layer-3, 128 Kbps (MS J-Stereo)

I think the MS J-Stereo mp3 format must not be supported by
mp3 players. At least it is not working on mine.
Do you know of a way with Flash lite or Flash to
programmatically convert MS J-Stereo to plain Stereo mp3 such that
they will play on cell phones and players in a flash lite appl?
Thanks!
Bob

I am not familiar with MS J-stereo but there should be
applications around on the internet that can convert.
The Flash IDE will not help to convert mp3s, unless you are
importing the mp3 for use inside the SWF, and not as a device sound
loaded with loadSound().

Import problems FCP7 with MPEG-2 Video, MPEG Layer 2

Good afternoon everyone...
I have a file that is an MPEG-2 Video, MPEG Layer 2 with a .mpg Extenshion and I am having problems importing it into
FCP 7. I have tried MPEGStreamClip, Compressor and a low end product called Total Video Converter. In FCP 7 I tried media manager and Log and transfer, but FCP did not even recognize it.
THE PROBLEM IS that when ever I convert the video it has a lot of video noise.
When I convert the video, I use proven the following presets DVDPro/DV, DVCPro720, XDCamEX 720. (I have
not tried Pro Res yet)
Does anyone have expeirence with these kinds of Mpeg2 Transport or Mpeg2 Program streams? Are there any QT plug ins?
-M

Michael...
Mpeg Streamclip is my go to program...
In MpegStreamclip the video does not show up, just a white box so I moved to Apple Compressor and Total Video Converter. Apple Comp and Total Video Converter could play and convert the clip.
(Do I need a plug in for Streamclip?)
Below you will find the stream info:
Duration: 0:23:41
Data Size: 1.04 GB
Bit Rate: 6.26 Mbps
Video Tracks:
224 MPEG-2, 720 × 480, 16:9, 29.97 fps, 6.00 Mbps, 4:2:2(!), lower field first
Audio Tracks:
192 MP2 stereo, 48 kHz, 224 kbps
This appears to be a fairly robust formated file.
Let me Know if you need anything else to help.

Why only 128 kbps in Music Store?!?

Why is it not possible to buy music from the iTunes Music Store in a better quality than 128 kbps?
The standard should be at least 192 kbps if this is a serious alternative to purchasing the actual CD. At least the user him/herself should be able to decide the kbps of your downloaded files, like you do when you import a CD into iTunes.
I was not happy at all, when I listened to my newly purchased Coldplay X&Y album on my stereo (through an Airport) last night (or in my iPod this morning). Honestly, I kinda feel like I've been ripped off a little bit.
Please don't make our expensive iPods and home stereos sound bad!

Thanks for your reply. I've also written my request through the link you sent me, and through another channel: http://www.apple.com/support/itunes/musicstore/songs/
...where Apple states that quality rivals that of an actual CD:
"Purchased songs are encoded using MPEG-4 Advanced Audio Coding (AAC) format, a high-quality format that rivals CD quality. Songs purchased and downloaded from the Music Store are AAC Protected files and have a bitrate of 128 kilobits per second (kbit/s). The file extension is .m4p."
...which I don't think anyone really agrees with.
If the record companies really placed the 128 kbps restriction on Apple, you would think that such a powerful organisation as the iTMS could easily make them change their mind. I'm sure that all the labels and bands would rather offer their music in 192 than not offer it at all.
Why spend millions of dollars on recording and production and then make the final product sound bad, when it doesn't have to?
I've tried to find other music stores that offers the songs in a better quality (e.g. 192 kbps), but so far I haven't found any. Any ideas?

Syncing with 128 kbps conversion

Whenever I try to sync my playlist, I have around 50 songs that somehow don't make it. I always get an error pop-up after: "iTunes could not copy "[Song Name]" to the iPhone "[iPhone]" because the file could not be converted."
I have it set so that files will be converted to 128 kbps when they're transferred over, and they sync from a specified playlist. Almost all the files that can't be converted are MPEG files...does anyone know why this isn't working out?
Thanks in advance.

For what it's worth, I have the same problem. I get that same message for 27 songs. No idea how to fix it, though I've fished around on the web a bit.
Sorry I can't be more helpful.

"high-quality" of 128 kbps versus higher rates

In a previous discussion a user was asking re difference between different bit
rates one answer clearly expressed dissatisfaction with 128 kbps for music such as instrumental and for music that is intended for streaming to a good stereo.
wondering if other users have a similar experience -- I am in the process of
importing a huge number of files and I wonder if its worth going to the higher
rate for all of my favourites.
I have a lot of space at the moment on my hard drive but I don't want to waste it if I don't get much improvement in quality. Unfortunately I can't test
it right now because I don't have a decent stereo system yet.

This was originally posted by the incredible Sparky the wUnderdog with help from MacMuse:
As a general principle, you can fit more CD's on your iPod if you encode at lower bitrates (making smaller files), but at the cost of audio quality. Apple Lossless promises to capture all the data on the original CD (thus preserving quality) but coded so the file takes half the space. MP3 and AAC (an implementation of variable bit rate MP4) both eliminate some of the information on the CD in order to compress the digital recording into ever smaller files--the lower the bitrate, the smaller the file, but smaller files mean more information lost and consequent poorer sound quality.
AAC files ripped in iTunes certainly sound better than its MP3's, with audio quality close to the best LAME MP3's at higher bitrates. With the type of music I listen to most often, sound quality declines substantially as bitrates fall below 256kbps, but LAME or AAC @ 256kbps sounds pretty darned good, and at 320kbps LAME alt-preset-insane is amazingly faithful to the original. However, many users claim that with the music they listen to they can't hear the difference between 192 or even 128 kbps files and the original CD source, so they naturally choose lower bitrates to fit more "songs" on their iPods.
CDs take approximately 10MB per minute of music; Apple Lossless takes 5MB/minute; LAME insane takes 2.5MB/min; AAC or MP3 at 256kbps take 2MB/min; and iTunes Store files (AAC@128kbps) take 1MB/min. At these rates, a 20GB iPod (really 18.6GB) can hold anywhere from 30 hours to over 300 hours of music. (iPod marketers express this potential playback capacity as "songs," figuring 4 minutes per song--thus 300 hours at 128kbps = 4500 "songs.") You will need to listen to samples ripped with different bitrates and codecs to determine the optimum tradeoff point for you between quality and quantity. It's worth taking some time to do this at the start as it sure beats reripping everything in your collection 2 or 3 times to get it right later.
So far as convenience goes, nothing beats iTunes's one-step process. To change bitrate as you import from CD, go to the iTunes menu>Preferences, select the Importing tab, choose AAC or MP3 encoder in the "import using" selection box, then choose "Custom" in the "setting" box, and the window permitting bitrate selection will pop up. If you choose iTunes MP3 encoder, at least use VBR (variable bit rate) to maximize the sound quality. (VBR increases sample size as data complexity increases.)
If you would prefer LAME MP3's, fear not, for the easy-to-use CDex ripping software is a free download and requires only one simple extra step to get the files into iTunes for transfer to your iPod. Now if AAC sound quality is comparable to LAME MP3, you might wonder why you should even consider LAME: Because of portability to other devices. At present, hardly anything but iPods can read AAC's or Apple Lossless, but almost everything reads MP3's. So if you plan to burn CD's of your compressed files for playback on your home or car CD player (for instance), it would be wise to choose MP3.
One other consideration specific to the iPod- It has a 32MB cache (If you don't know what a cache is, read the last paragraph of this page: iPod + iPod Mini- Batteries). Keep individual file sizes below 25 MB as the rest of the 32 MB memory holds the iPod's Opperating System. If you choose a compression rate that results in large files (i.e. Lossless), then the cache won't hold very much 'music' and the hard drive will have to spin up frequently to fill it, and that will shorten your battery life somewhat.

ITunes won't synch 80 songs at 128 kbps despite having 5.5 GB of space on iPod. iTunes or iPod error?

My 4th gen 30 GB iPod has 5.5 GB of space on it (this is what iTunes says before I hit sync). I want to add about 80 songs to be automatically downconverted to 128 kbps. When I try to update iPod, iTunes indicates iPod is overcapacity by over 19 GB and won't add new songs. Something is not right with either iTunes or iPod. Is anyone else having the same problem?
All I have is music on the iPod. No apps, no games, no movies, just music.
I just subscribed to iTunes Match. Could this be the reason why this is happening? Is anyone else having the same problem?

I'm having similar problems. Up until 4 May 2009 when I installed Windows 7 RC1 on it, I had one XP SP3 PC which was running iTunes properly and syncing and autofilling my iPod shuffle. The laptop described below no longer let me run or re-install itunes on it since I upgraded it to XP SP3. When I switched to Windows 7 RC1 on the XP desktop that was running iTunes properly, I was able to re-authorize that PC for iTunes 8.1 (64 bit) but after that, could not sync nor autofill, nor restore the ipod, but I could buy songs and play all my songs under Windows 7 RC1. Yesterday (Friday 15 May 2009) I got a new HP Compaq 6735s 2 GB RAM 160 MB HD, Vista Home Basic laptop and today installed a fresh download of iTunes 8.1 on it. Now that laptop won't let me even authorize iTunes on it. Any time I do anything in iTunes that involves contacting the web, it comes back with unknown error -3212 unable to contact server. This comes up when I try to authorize, and when I try to play some of my purchased songs on the laptop -- it demands that I authorize the laptop then tells me I can't (error -3212). Also when I try to restore the ipod, I get the same -3212 error trying to get to the update server. I turned off both the windows firewall and stopped the McAfee firewall but that didn't help. I renamed the Hosts file also without result. There doesn't appear to be a tech support email address or trouble reporting web form that can be used to report this and the search and troubleshooting FAQs on the itunes website seem to be pretty useless in resolving this. The phone numbers are either sales related or they want $59 an incident to give me a call back. Seems like Apple is drifting into the Yahoo and Google approach to tech support -- basically, "discuss your problems among yourselves, suckers, we're too busy raking in the cash to bother with your problems."

Error -50 when trying to convert to 128 Kbps AAC

I try to convert all my files to 128 KBPs but about halfway through one of the songs gets an error (-50) and it wont go on. I wanted to do this because I heard it makes the songs take up less room and my iPods almost full. If it helps any I'm using the latest version of iTunes on Windows 7 65 bit.

Unless you happen to catch the name of the song it's syncing, I don't see how you are going to narrow this down.
While syncing, if you click on the ipod in the left list, you can make the little triangle point down. Then click on the word Music underneath that. (Not the main music library, in other words)
There will be little circles next to each song when that song is getting synced. There will also be the song name in the top oval. If you happen to catch that song's name, you could uncheck it and itunes won't try to sync it.

Hi, I'm trying to convert my music to 128 kbps AAC, How do I do that?? Thank you

Hi, I'm trying to convert my music to 128 kbps AAC, How do I do that?? Thank you

Hi Dawn,
Open iTunes and select preferences under the itunes menu. under the General tab look for import settings. Select AAC as the encoder and 128kbs. then open your main iTunes window and select some music you want to convert, then look under the advanced menu and one of the options should say create AAC version. Andor if your sending music to an iphone or iPod there is anoption in the device preferences that will do the same thing.

Change the convert to 128 kbps before transferring to iPhone option?

iTunes gives you the option to convert all higher-bitrate audio to 128 kbps AACs before transferring to my iPhone. Great, except I'd prefer a little higher quality. Is there any way to make it, say, covert to 192 kbps VBR AACs instead?

if you're converting from a lossless format, you could use this:
[_*Lossless to AAC Workflow v2.2*_|http://dougscripts.com/itunes/scripts/ss.php?sp=losslessaccworkflow]
Two scripts assist with importing/managing Apple Lossless or AIFF audio files and sending converted AAC copies to a mounted iPod set to "manually manage songs and videos".
*Lossless to AAC Workflow (CD->iPod):*
Imports each enabled CD track as an Apple Lossless or AIFF file
Makes a converted AAC copy of each imported file
Adds the AAC file to iPod, deleting the original AAC from iTunes.
*Lossless to AAC Workflow (iTunes->iPod):*
Makes a converted AAC copy of each Apple Lossless or AIFF track selected in iTunes
Adds the AAC file to iPod, deleting the original AAC from iTunes.
In this way you can keep archived lossless files on your hard drive, and manageable AAC files on your iPod.
+Yes, iTunes 9.1 will auto-encode tracks to iPod, but only 128 kbps AAC; these scripts enable use of your Custom AAC encoder setting.+

Why is the quality of the DVD not as good as original mpeg layer 3

I have produced a wedding album slideshow in keynote (this allows me the 'flop' transition giving the appearance of the pages being turned)
I tried exporting staring into iDVD but the slideshow quality was awful on the DVD.
I have now tried exporting it from keynote as H264 1920 x 1080, mpeg layer 3. This produces a very hi quality quicktime movie (about 200mb)
From there I have tried importing it into iMovie at widescreen and then sending to iDVD, outputting at professional quality. I've also tried dragging it straight into iDVD.
Resulting DVD is awful and more blobby than pixelated. The intro generated by iDVD is fine however.
Any ideas on what I am doing so wrong?
Please help, I'm doing this as a favour for a friend.
Kosh

DVDs are low resolution devices by todays standards; only about 648x480 pixels for NTSC discs.
Image size for iDVD slideshows should be: NTSC standard 720x540 pixels, widescreen 854x480 pixels. PAL standard 720x540 pixels, widescreen 854x480 pixels. Going to larger images won't help and can make things worse.

HT1535 How do i convert higher bit rate songs to 128 kbps AAC

I am trying to sync selected songs to my Iphone 5 from my itunes library. I have recently taken my computer to be fixed and all of my music documents were taken off but the files were replaced shorty after. I re-downloaded itunes and it is up to date. My iphone is also on the ios 7.0.4. Whenever i plug my phone in to be synced it never goes past the "waiting for changes to be applied" step. While my phone was still connected i went to the "On this iphone" tab and clicked the autofill button and a message came up that said i must convert higher bit rate songs to 128 kbps ACC to allow the songs to be copied to my iphone. How do i do this? Also, once this is done will it solve my problem with transfeering my songs from my library to my iphone?

Sid,
With the device connected, click the Summary tab and you will see the "Convert higher bit rate..." option. Set it to 128. See picture below:

Using the "Convert higher bit rate songs to 128 kbps AAC" feature...

I recently discovered the "Convert higher bit rate songs to 128 kbps AAC" feature and used it to copy my entire 70 GB music library to my 64GB iPad. The music library now occupies only 45 GB. Awesome!!!
Unfortunately, the whole process took well over 24++ hours on my quad core Windows 7 computer (takes about 6 seconds per track). Questions:
1. Is it possible to speed up the process? Even though I am using iTunes 64-bit version, it seems that at no point is more than a single core being used at 33%. Seems to me like overall 8% of the CPU (33% / 4) capacity is being used for the conversion and 92% is being left idle. Is this just bad programming or is there anything I can do to speed up the process? Others see similar problems?
2. Now I have already started dreading the day, I need to restore my iPad (e.g., when OS version 4 becomes available). I would hate to have to do this process all over again. Should I need to restore my iPad, is there anyway I can force iTunes to back up the 128-bit AAC versions on my computer and restore it up from there?
Any insights into both these questions will be deeply appreciated.
Cheers,

So, I am wondering why iTunes uses only 8% of the processor power in converting the songs.
Possible reasons not to grab more of the CPU power (1) maybe the process is I/O bound due to all the writing, and is not processor limited? (2) since conversion is almost always a background program, and the user will typically have other things going on, maybe it intentionally limits CPU use?
I ran a few quick experiments (out of curiosity) and think the answer is #2. No apparent technical reason but potentially a limitation introduced by Apple's engineers to maintain a good user experience (for some people at least). I fired up 4 instances of dbpoweramp and ran multiple conversions and found that the process goes faster than what iTunes can do by an order of magnitude. With luck, someday Apple will have an option for users to select how much of processor bandwidth to be allocated for the conversion.

Purchased AAC, unprotected, 128 kbps

iTunes 11 tells me some of my iTunes purchases are unprotected 256 kbps (Purchased AAC audio file), some are protected 128 kbps (Protected AAC audio file), and some are unprotected 128 kbps (Purchased AAC audio file). I thought all the unprotected tracks were 256?
All the 128 kbps unprotected tracks have a cloud download icon telling me I can download a new copy. But when I click the cloud, I get a clock icon for a few seconds, and when it's done nothing seems to have happened except the cloud icon is gone. The track is still 128 kbps.
None of the 128 kbps protected tracks have a cloud icon, but I tried deleting two of them and then I got the cloud icon. When I downloaded the tracks, they became "Purchased AAC" rather than "Protected AAC", but they were 128 kbps.
Questions:
1. Why do I have so many unprotected 128 kbps purchases? I thought all 128 purchases were protected and all 256 were unprotected. For example, my Styx Crystal Ball album, purchased in 2003, is still 128 but unprotected. Did Apple un-protect some older files on my Mac?
2. Why are replaced tracks 128 rather than 256?

I figured out the cloud icon doing nothing thing:
Once upon a time I bought some albums and tracks from iTunes before they were available at 256, but have since bought some of them on CD and ripped them at 256, and deleted the 128 files from iTunes. The cloud icon is telling me those purchases are available in the cloud, and not on my Mac. I can apparently play them without downloading them, with a slight delay, or I can download them. When I download them the cloud icon goes away (it's now on my Mac), and I now have two copies: the one I just downloaded and the one I ripped from CD.
Still unresolved:
When I delete and re-download tracks I've purchased, the replaced tracks are 128 rather than 256. The blog articles I've read said they'd be 256. I'm guessing that's bad info, and that I can only download it at the bitrate I originally purchased it. Right?

Changing the encoding to 256 kbps from the standard 128 kbps

I just read an article on the Internet about earbuds, especifically the Shure 4c, in which it was "highly reccomended" to change the encoding to higher levels such as 256 kbps from the "standard" 128 kbps.
The question is, once you have all your songs in iTunes downloaded at the standard 128 kbps, how do you change the encoding to 256 kbps, without deleting everything and transfering all your CDs, etc, all over again? Can it be done without the obvious, do it all over?
Thanks

Pedro, this will not be possible. You can't convert a lower bitrate to a higher one & gain anything in quality. The maximum data has already been compressed & removed under the lower bitrate & can't be put back. If you truly want the benefits of the higher bitrate, it would be much better to re-import your CD's at the 256 bitrate. Post back if you have any questions.

No sound in avi files (MPEG Layer 3 format)

Ok. here's another take on this problem maybe someone can please help me with. overall objective is to convert avi files to "ipod ready" files using quicktime. at first when any of these files were opened in quicktime, i had no sound and a white screen while the file was "playing". it took me a very long time but finally found the necessary video codec so i now have the video.
however, i am still not getting anywhere with the sound problem. when i go to video properties in quicktime it says the audio track of the files are in MPEG Layer 3 format. so, naturally i began searching for this audio codec. when i found one on freecodecs from Fraunhofer, downloaded, and installed, nothing changed. unfortunately i cannot find any other version of this codec and cannot figure out how to get quicktime to use the codec from Fraunhofer.
Please help!!!!

Hey. Thanks for the info. I have found the program and will give it a shot. In the meantime I have been using a program I found called Digital Media Converter which seems to be working great (a little slow but does the job). However, I was wondering if one of you who is most familiar with the Windows OS could answer a question. I have encountered an error when I tried converting video files in the past and with this new program. It seems to be internal to Windows. After a file is converted to an mp4 and I go to the conversion folder to look at the file...whenever I click on that mp4 file or go to use it the Windows Explorer crashes giving one of those report sender windows that Windows generates after a problem. Now what is really strange is that despite Explorer crashing, I can move that box out of the way, continue to work with the file (place it in iTunes), delete the original (as iTunes stores its own copy), reset the Explorer, and then it's like nothing ever happened.
Is it normal for the Explorer to crash under these circumstances? And, is there anything I can do to fix that?
I'll be trying the MPEG Streamclip program in the meantime. I have located it on the web but not installed just yet. I'll get back to you. Thanks for all the help guys!
