ITunes Purchased HD Playback Data Rates

Recently downloaded a free "digital copy" SD movie and was wondering what the typical playback data rate range would be for purchased HD content. I.e., I assume it is still limited to TV1 compatibility but am wondering what the actual excursion range is like since I do not normally purchase content but am considering this option in the future.

If you purchased an HD show, did you sync the SD or HD version?
You need to sync the SD version?

Can I list my purchased items by date? In Itunes on a PC

On the latest Itunes on a windows 7 PC can I list my purchased items by date so I know what I downloaded in the order of date pourchased?

Use View > View Options... or right click on the column headings to display the Date Added column, then sort on it.

Best Data rate and format for Big Screen Playback

I am a video producer supplying content for a tradeshow display consisting of 18 flat screens oriented vertically, 8 over 8. Very heavy duty Windows playback machine, with 3 graphics cards, 1 for each set of 6 monitors. The total pixel size is 3240x 1280 px. We have produced a number of full screen and smaller movies that the interactive programmer is trying to intergrate into a Flash program where some videos will play full screen, and others in smaller windows (those were produced in 1920x1080). All videos were mastered at the specified pixel count, square pixels, progressive, and output in Pro Res 422, 44.1K audio. Flash is being used to create the interface, and I am transcoding to .F4V at lower bit rates like 4, 6, and 9 Mbps. They are having trouble playing these movies back smoothly. We have done similar projects in the past with Director without issue. Of course they are blaming the video, I am offering to encode in any format at any data rate they suggest. Can anyone suggest a direction here?

Are you trying to burn a standard DVD or are you trying to put a QuickTime .mov file on DVD media?
A standard DVD doesn't worry about file size (only the duration).
A "data" DVD is limited to the type of media used. A single layer DVD is about 3.7 GB's.
In order to make a data DVD you need to keep the data rate low enough to not exceed the DVD media playback abilities. They can't handle the higher rates found in many of the preset options.
You can avoid all of these headaches by telling the viewer to "copy" the .mov file from the DVD to their Desktop. Then nearly any of the presets option will work.
H.264 is a great video codec and the "automatic" preset should work just fine. Use "multi-pass" for best quality (takes a very long time). Remove the check mark for "Audio" since your file has none. Leave it checked and you waste file size because a silent audio track would be added.

Does watching iTunes purchases use data?

I recently disconnected the WiFi I normally use so I haven't been able to stream videos online. Instead I have been watching my purchased TV episodes from my iTunes but on the top left by the 3G sign, the circular icon moves as if it is using 3G to watch the video. I'm concerned about my data useage limit so would like to know if watching iTunes purchases is in fact using 3G data.

Turn off the 3G service and should have nothing to worry about.
Once you have completely downloaded a TV show or a movie, you do not need an Internet connection to watch them so just turn off the service - period.
I assume that the iPad is searching for a signal even if you are not currently using the Internet so I would imagine that you are still using some data - maybe e very small amount - but some data anyway.
I should stress that I am assuming this - it makes sense to me, I don't have a 3G iPad, but if you turn off the cellular service, you can't be using data.

Data rate of AAC file converted with iTunes 7.5.0.20

I have just noticed data rate of files converted to AAC with iTunes revision 7.5.0.20 deviate slightly from preset converting data rate in random manner. For example browser shows files with preset 192kBit/s data rate as 193 or 195kBit/s data rate, ones with 320kBit/s preset as 321, 322, 325kBit/s etc.
Is this a encoder bug or a music content dependent data rate adjustment?
Anyone a suggestion?
Thanks and best regards

Try the following user tip with that one:

If you sync the episodes downloaded to your computer over to the device then there is no need for 3G data usage, however if the podcast app is set up to check for new episodes it may refresh the feed, which could involve a tiny data transfer.

ITunes data rate?

Before buying music from the iTunes store I'd like to get an idea of what quality to expect. My wife and I are audiophiles and music lovers and are somwhat particular about quality. We've discovered that when encoding CD's to MP3 we generally have to encode at 192 kbps or higher to get decent quality without too many artifacts, expecially with complex music such as orchestration or with lots of bright sounds like cymbals. (we've tried several different CODEC's). Some people here have said that AAC/.m4a produces better quality for a given data rate than MP3, but most of the serious objective tests I've seen indicate that any difference is either trivial or nonexistent.
So what is the bitrate for music on the iTunes store?
Thanks in advance.
iPon Nano Windows XP Pro

At present the bit rate for iTMS tracks is 128 KBPS
Yuck!
One other thing to keep in mind is that the iTS store sells songs encoded at 128 kbps with the AAC codec which Apple claims is equivalent to a 160 kbps mp3-encoded file.
I'm not trying to sell you anything here because in the end it's going to be your ears that will decide whether the audio quality is acceptable or not but you could buy one or two tracks to see hear what you think. If you're happy with the quality, you can proceed to buy more. If not, you can write the whole thing off as a fairly inexpensive learning experience.
And if you're interested in a more technical comparison of the AAC and MP3 formats, have a look at this article .

ITunes for Windows freezes when importing a library. I have a large but not huge library of mostly iTunes purchased music on two authorized computers and would like to sync the files, export the library as a playlist, and import it on the other computer.

I am running iTunes for Windows 10.2.2 on Windows 7 Home. I have my iTunes library on both this computer and another authorized machine running Windows 7 Professional. I have a large but not enormous library, as I'm one of those people who doesn't pirate, use torrents, borrow from a dozen friends, or whatever other shades of gray you might imagine. It's mostly iTunes purchases with my old CD collection imported. I have started using the following technique to sync my libraries between my two authorized computers, an ability which you can probably all agree should one day be added to iTunes -- that would be different from Home Sharing, because the music would be stored locally and thus available on the road. With the added benefit of the entire library being backed up on the other machine in real-time. Anyway, when I switch from my desktop to laptop and vice versa, I use the following technique:
Connect both machines to the home network. One machine is the "Active" machine, which has most recently been used for iTunes media, purchases, ratings, etc.
On the "Active" machine, File-->Library-->Export. Save the file as "Library.xml" on the shared drive of the other machine.
Right-click "Library.xml" where it's been saved, and open another file that has two lines in it: The root path of the iTunes library on one machine and the root path of the iTunes library on the other machine.
Do a find/replace all in Notepad to make the library XML file point to where the files will be saved on the "Inactive" machine.
Run Microsoft SyncToy to synchronize the files between both music libraries; the most recent files win. This avoids copying the entire multi-gigabyte library over the network.
Open iTunes on the "Inactive" machine.
Go to Music, Select All, Delete. Keep files.
Do the same for Movies, Music Videos.
Go down to Playlists, select the top one, hold down the delete button until they're all gone.
File-->Library-->Import Playlist. Choose the "Library.xml" file you saved.
First a status bar comes up that says, "Importing library." It has the continually-scrolling progress bar, not the one that starts on the left and steadily creeps right. Then after about 30 seconds, that clears out. Wait. Typically a few minutes. Eventually a status bar will pop up saying something like, "Evaluating gapless playback information," or something like that.
The "Inactive" computer is now the "Active" computer. I can now play my library, it has all my playlists and metadata from the other machine.
Delete all the duplicate playlists named "Music," "Genius," "Purchased," and "iTunes DJ."
Well, I just upgraded to iTunes 10.2.2 a few days ago and tried to do this again like I've done it dozens of times before. Now, iTunes just goes unresponsive after the library import. It got through the "Importing library" bar to the long wait and stopped. I can still multiprocess and use other programs, but iTunes is hovering back there not responding to clicks. Task Manager doesn't seem to think iTunes is using my CPU, and I don't see my hard drive rattling. Any thoughts on why iTunes might hang up when importing a large library?
... Also, please help lobby Apple to come up with a network sync tool built into iTunes for a user with multiple authorized computers. Something different than Home Sharing so I can pull my laptop off the network and still have the synced library with me. And all my metadata changes will sync. The technique I use seems a little kludgey, don't you think?

iTunes isn't an editor. You need an app that's intended for editing audio files, like Adobe Audition (http://www.adobe.com/products/audition.html) or Audacity (free in the App Store).

ITunes wiped all but iTunes purchased music from my iPad mini and my iPod nano instead of transferring the cd uploads into iTunes. Is there any way of recovering my music. Very disappointed!

Initially things worked fine. I was very pleased. I had my music library in itunes, on my Ipod nano, and a thumbdrive to back up most of my music.
When I tried to sync the music from itunes onto my new ipad mini last week it deleted the albums in itunes leaving me with only purchased itunes items in the account, On the new Ipad mini CD's from my collection could not be played but they were in fact listed. My new mac will not read the music files I backed up onto a thumb drive or show the uploaded CD music collection. Additionally when I logged into itunes with out any devices connected from my PC the itunes account was completely up to date with my CD's and purchase items in Itunes. As soon as I tried to sync it with my Ipad mini that virtual access to the collection was wiped out leaving only purchased items.
By trying to upload CD music from my Ipod nano into Itunes (originally uploaded into itunes from CD's and synced to the ipod nano in the first place, taking more than a weeks time), I am prompted to reset the entire ipod nano to factory settings (it gives no other option). I was following the instructions emailed to me from the applecare team. This was my only recourse for recovery of the lost music files, the only device left that had my album collection aside from the owned CD's. Now the ipod nano is being wiped clean and left with only the itunes purchased music ( same thing that happened with the itunes account and now the Ipad). When I disconnect the ipod nano to see if there are any albums still left on the device, it gives me an error that it was improperly disconnected.
I just wanted to add the music from itunes to my new mac and the new ipad mini. Instead I have lost all of my uploaded CD's and now have only purchased items in itunes, the new ipad mini, the new mac, and the ipod nano. I have to re-upload my entire music library into itunes/icloud from CD's again and hopefully be able to then sync it with my new devices.
However it may be better to buy the itunes purchased music on CD's from a store, Cut my losses while I can and never buy anything from apple or itunes again. Atleast I will not have my entire music collection wiped out for moving it between my own devices. Itunes match doesn't do **** either. I have wasted alot of hard earned cash on devices products and itunes purchases by converting to apple products and services.
What a big mistake.
Very dissapointed with the interface. Very Very Dissapointed!

Had the same issue when I changed computers. I backed up my I-tunes files, including CDs, but I-Tunes will not recognize anything but Apple purchases now. There were 300+ CDs in that original catalog.

How do i back up my iTunes purchases. There is no back up option under library any more?

Hi all,
I want to bak up all my iTunes purchases as i have not done this for a few years. I looked for a "how to" but the Apple site siad to go to back up library under file/librabry but this no longer exists?
How can i just back up my store purchases not my whole library?
Thanks

You really should backup the entire library. This User Tip shows how, and the same tool can be used to backup other important data you may have.

How do I back up my iTunes purchases to a cd?

Hello:
I am unable to find out on the apple website any information about how to back up iTune purchases to a cd. Could you please explain to me how it is done.
Thank you.

While that method given in the support doc for backp to a drive will work, it isn't very efficent to use on a routine basis.
Fast backup for iTunes library (Windows)
Grab SyncToy 2.1, a free tool from MS. This can be used to copy your entire iTunes library (& other important data folders) onto another hard drive or network share. You can then use SyncToy periodically to synchronise or echo your library to the backup. A preview will show which files need to be updated giving you a chance to spot unexpected changes and during the run only the new or updated files will be copied saving lots of time.
If your media is all organised below the main iTunes folder then you should also be able to open the backup library on any system running the same version of iTunes, regardless of the drive letter or path it appears on.

I have a question about Data Rates.

Hello All.
This is a bit of a noob question I'm sure. I don't think I really understand Data Rates and how it applies to Motion... therefore I'm not even sure what kind of questions to ask. I've been reading up online and thought I would ask some questions here. Thanks to all in advance.
I've never really worried about Data Rates until now. I am creating an Apple Motion piece with about 15 different video clips in it. And 1/2 of them have alpha channels.
What exactly is Data Rate? Is it the rate in which video clip data is read (in bits/second) from the Disc and placed into my screen? In Motion- is the Data Rate for video only? What if the clip has audio? If a HDD is simply a plastic disc with a dye read by "1" laser... how come my computer can pull "2" files off the disc at the same time? Is that what data transfer is all about? Is that were RAM comes into play?
I have crunched my clips as much as I can. They are short clips (10-15seconds each). I've compressed them with the Animation codec to preserve the Alpha channel and sized them proportionally smaller (320x240). This dropped their data rate significantly. I've also taken out any audio that was associated with them.
Is data rate what is slowing my system down?
The data rates are all under 2MBs. Some are as low as 230Kbs. They were MUCH higher. However, my animation still plays VERY slowly.
I'm running a 3GigRam Powerbook Pro 2.33GHz.
I store all my media on a 1TB GRaid Firewire 800 drive. However for portability I'm using a USB 2 smartdisk external drive. I think the speed is 5200rpm.
I'm guessing this all plays into the speed at which motion can function.
If I total my data rate transfer I get somewhere in the vicinity of 11MBs/second. Is that what motion needs for it to play smoothly a 11MBs/second data connection? USB 2.0 is like what 480Mbs/second. So there is no way it's going to play quickly. What if I played it from my hard drive? What is the data rate of my internal HDD?
I guess my overall question is.
#1. Is my thinking correct on all of these topics? Do my bits, bytes and megs make sense. Is my thought process correct?
#2. Barring getting a new machine or buying new hardware. What can I do to speed up this workflow? Working with 15 different video clips is bogging Motion down and becoming frustrating to work with. Even if only 3-4 of the clips are up at a time it bogs things down. Especially if I throw on a glow effect or something.
Any help is greatly appreciated.

Data rate DOES make a difference, but I'd say your real problem has more to do with the fact that you're working on a Powerbook. Motion's real time capabilities derive from the capability of the video card. Not the processor. Some cards do better than others, but laptops are not even recommended for running Motion.
To improve your workflow on a laptop will be limited, but there are a few things that you can try.
Make sure that thumbnails and previews are turned off.
Make sure that you are operating in Draft Mode.
Lower the display resolution to half, or quarter.
Don't expect to be getting real time playback. Treat it more like After Effects.
Compressing your clips into smaller Animations does help because it lowers the data rate, but you're still dealing with the animation codec which is a high data rate codec. Unfortunately, it sounds necessary in your case because you're dealing with alpha channels.
The data rate comes into play with your setup trying to play through your USB drive. USB drives are never recommended for editing or Motion work. Their throughput is not consistent enough for video work. a small FW drive would be better, though your real problem as I said is the Powerbook.
If you must work on the powerbook, then don't expect real-time playback. Instead, build your animation, step through it, and do RAM previews to view sections in real time.
I hope this helps.

My ipad does not appear in itunes. I am OS 10.6, itunes is up to date, I have restarted computer and ipad and switched usb sockets. Dont know if its related, but I can no longer see my sony handycam in imovies too.

My brand new iPad 2 does not appear in iTunes. I am OS 10.6, iTunes is up to date, I have restarted computer and iPad and switched usb sockets. Don't know if its related, but I can no longer see my Sony Handycam in iMovies too.

What content are you wanting to copy of the iPad ? You should be able to copy off anything that you've purchased from Apple (films, music, ibooks, apps etc) by connecting the iPad to your computer's iTunes and doing File > Transfer Purchases. If you want to copy off music copied from your own CDs or purchased from other sites then you will need to find a program for your computer that can copy them off – iTunes won't copy them off.
For photos taken with the iPad, copied to it via the camera connection kit or saved from emails/websites then you should be able to copy them off via the Windows camera wizard.
For photos that were originally synced from a computer you will need a third-party app such as Simple Transfer which can copy them off via your wifi network. But as photos are 'optimised' when they are synced to the iPad, any that you then copy back to a computer may not be exactly the same as they originally were on your computer.
Content in third-party apps (documents and files etc) then how you copy that content off will depend upon what the apps that they are in support e.g.either via the file sharing section at the bottom of the device's apps tab when connected to iTunes, via wifi, email, dropbox etc.

How can I move my itunes purchases to a different computer?

How can I move all of my itune purchases on my old computer to my new computer?

A third point of view...
Moving your iTunes library from one computer to another...
Method 1
Backup the library with this User Tip.
Restore the backup to your new computer using the same tool used to back it up.
Deauthorize the old computer if you no longer want to access protected content on it.
Keep your backup up-to-date in future.
Method 2
Connect the two computers to the same network. Share your <User's Music> folder from the old computer and copy the entire iTunes library folder into the <User's Music> folder on the new one. Again, deauthorize the old computer if no longer required.
I'd recommend method 1 since it establishes an ongoing backup for your library.
