Menu Bit Rate

I'm using DVD Studio 2 and I have an m2v file and AC3 audio for my menu with titles over it. Very basic. But my bit rate is way too high. When I check my menu bit rate a bit rate viewer it says my nominal bit rate is 8 MB per sec, but I have my settings in DVD SP set to 5.5 max and target. The original m2v file I'm using was encoded with ProCoder and had a nominal bit rate of 6.2. What can I do to make sure I don't have such a high bit rate. For when we duplicate the master DVD we have shudders and pixelation in the menu, even though the master plays just fine. I need it to be lower for our duplicator.

Wow, so it is the titles then. Yeah, I wondered because I have made other DVDs with DVD SP 2 before, but never actually added titles to it, Just menu and play buttons. So the buttons don't really affect the Bit rate too much, but the titles do. Man, thanks so much. I think I have a really good idea on how to fix that then. Like you said, go put those titles in using Final Cut or Avid. Nice, thanks.

Can no longer change bit rate in AAC custom import settings

I've been re-ripping all my CDs at the new higher bit rate. My import settings were AAC Encoder -- custom, originally set to 256 kbps, VBR, and auto for the other two settings. However, some CDs I wanted at a lower setting, so I would go change the bit rate to either 192 or 224 (just so I'd have more room on my ipod) and there wouldn't be a problem. But now it's stuck -- the pop-up box no longer opens when I choose import settings, AAC Encoder, Custom, so I can't change the bit rate or anything else, and it's stuck on 224 kbps. I can still change bit rate and other settings in the custom menus for MP3, WAV, etc., just not AAC. A repair install of iTunes did not fix the problem.

Hi, Ed. I am running iTunes 9.0.3.15. When I click custom, the settings description in the details box display what they were before this thing happened = 112 kbps (mono)/224 kbps (stereo), VBR, optimized for MMX/SSE2. The pop-up dialogue box that used to appear (where you could choose the specific bit rate from the drop down menu) does not appear at all.
However, when I choose anything other than AAC Encoder, and then pick custom, the pop-up box appears and I can choose the bit rate and adjust the other settings as usual. It's just not happening for AAC Encoder anymore. Since the total un-install (following Apple's specified order) and reinstall didn't work, I'm baffled how to fix this .... (If it makes a difference, I changed the bit rate in the custom box while a CD was being burned...Apparently that was stupid, but I had done it previously without incident.) Thanks.

How can I download music from itunes store at a higher bit rate than 128k?

I have been able to import music from cd's at bit rates higher than 128kbs by clicking into the preferences item under the "edit" drop down menu. however, I have not been able to locate a similar command for itunes music downloads. is it possible to increase the bitrate of music downloads from itunes faster than 128kbps? if so, how?
gateway Windows XP AMD 64

No, store downloads have always been ONLY 128 kbps. With new deal between EMI & Apple, sometime next month you will be able to download EMI artists only at a higher bitrate without the DRM, for a slightly higher price. For now, though, all downloads are still 128 kbps. Your import settings only affect the CD's you rip your self. Hope this helps.

Bit rate too high

I have been encoding a DVD all day, using the same settings (DVDSP's factory default for an SD DVD). I then had to replace some footage in one of the videos and that is when I strating getting the message about the bit rate being too high. The replaced footage was the same duration as the previous media and no additional video effects or audio were added.
I searched forums which suggested that I should delete a dvdstudiopro.plist file, but I can't find this file! I am running OS Lion 10.7.4 and the latest version of DVD Studio Pro.
Any ideas? (Thanks in anticipation)
Mike

The file is in: your user name/Library/Preferences.
Alternatively, you can download this free tool, which will remove the file for you and provides the option to backup your FCS Preference files.
Mac OS X Lion hides the Library directory by default, to access it temporarily bring Finder to the front, hold the Option key and select it from the Go menu bar item.
To have permanent access type the following into Terminal:
chflags nohidden ~/Library/
execute the command by pressing Return.

What is "Total bit rate"?

I have a reasonable idea of what bit rates are, measured in MB/sec or Kb/sec, but whenever I use "Get Info" on a video clip I get something like . . . . "Total bit rate: 26,571" . . . . just that - nothing else.
What exactly is it?
It's too low to be b/sec.
I am sure it is too high to be Kb/sec ?
What do they mean by "Total"?
I understand "Average" and "Maximum" but what is "Total"?

I can't tell you how many people use my studio and compress their video to fit exactly on a DVD-5, and then go over because they can't fit their audio or menu graphics, or subtitles, or anything else. They go over literally by about 1-2 MB, and don't understand that you can't just stuff it in there… One byte over is too big. That's a tough one for a lot of people to grasp, but always funny when they ask if there's anything they can do to make it fit without recompressing it. I just tell them to hit it with the hairdryer.

Unwanted automatic decrease in bit-rate upon saving. How do I fix this?

Hello all,
After a recent, unexpected computer crash, Audition seems to have lost all of my previously programmed presets and preferences causing one quirk in particular I wish to fix as soon as possible. Please help!!
When working with any MP3 file, as I make changes to the file in Edit view and simply hit ctrl+s, every time I do so a message prompt comes up saying "You may be saving to a compressed (lossy) format. Be sure to keep a backup of your original file if you wish to preserve full audio fidelity." After that, it proceeds to save the changes while at the same time decreases the bit-rate of the file to between 80-96kbps down from 128, 192, etc. It has never done this before, usually it would just make the save without altering the bit-rate also. I'm searching the menus everywhere to find a checkbox that I may have had un-checked before but has gone back to the default since the crash, but can find nothing. I really do not want this automatic downsampling to continue, in order to get around it I have to Save As every time, which makes for a lot more work having to delete the old copies and keep track of which are the edited versions I wish to keep. I work with tons of files, so this gets difficult.
I am using Adobe Audition 3.0 Build 7283.0 on a Vista PC.
I can't thank you enough for any help you might be able to offer. Here's a screenshot of the message itself: http://img809.imageshack.us/img809/8558/ausc.jpg

Hello SteveG,
Thank you for your prompt reply. Ah yes, I am aware of such a feature in the mp3 options menu, but do you know why my copy of Audition is behaving in this way and how I can get it back to the way it was? Saving As does save the file with the criteria I prefer, but it creates an extra copy that I'd like to avoid since cleaning up the previous versions of each file that are no longer needed can take a lot of work since the folders that contain them I work with are very large, having to be searched by hand to remove the unedited copies.
As where if I hit Save before it would just overwrite the file avoiding creating two of the same file (one with edits the other without), leaving its bit-rate intact instead of reducing it by as much as half at times. Having that aspect of Audition working again would be very helpful!
Thanks again,
Melissa R.

What are the best data and bit rate setting for uploading from final cut express to Youtube?

Can anyone suggest the best data rate and bit rate presets for uploading footage from final cut express 4 to Youtube? What settings will provide the best resolution, quality, and match the current youtube requirements?
Thank you in advance for your help,
Susan Kayne

It depends on whether you are using aspect ratios of 4:3 or 16:9.
Below is some simple guidance that will provide good quality with reasonably small file sizes.
The first part is for 4:3 video:-
1. File>Export Using QT Conversion.
2. The "Format" window should say, "QT Movie".
3. In "Use" select "LAN/Intranet" from the dropdown menu.
4. Click "Save" and when it has finished encoding, upload it to YouTube.
If you are making 16:9 video (Standard or High Definition) do steps 1 to 3 above.
Then when you have selected "LAN/Intranet" press the "Options" button and in the new
window that opens press the "Size" button and change the "640x480" to "853x480"
To do this you will have to click on the 640x480 and a dropdown menu appears.
Select "Custom" from the bottom of the menu and in the window that opens
you will see 2 boxes.
Put 853 in the first box and 480 in the second.
Click OK.
Then Save it.

Can no longer change bit rate in AAC custom import setting

I want to change personal settings of AAC, but I can't. Still only the last setting, that was 192 Kbps Stereo. My iTunes version is 10.7

Target & Max Bit Rate - A Little confusing Need file to be 15 GB Blu-Ray Help????

I have a 2 and a half hour project on PPro CS 5.5 that I want to encode in H.264 Blu-Ray. I want to get it to 15 GB.
What woud be the best settings to do so?
The Target Bit Rate and Max Bit Rate have a lot to do with it, but I am a little confused on what each of them really do.
I just want to get it to 15 GB and make sure the Estimated file size somewhat accurate.
Is 15 GB too big for a Blu-Ray?
Thanks in advance

Hi Jeff,
I just started to build just my menus with my QT files inside of them as a "Build to Folder."
I think I know why it's saying 7.1 GB used.
Since the menus in Encore stop and loop after 30 seconds, I did not like that.
I like to play a full song on each menu and then when the song ends, it starts again. If I did that on a standard 30 second menu in Encore, the song would stop every 30 seconds and start again. This was not acceptable to me.
This does not happen in DVD Studio Pro. In DVD Studio Pro, I can put in a full song with Videos in Video Zones, change the loop time to the length of that song, and the menu would play that song, and loop again when it was over.
I wanted to do this in Encore, so I had to make the menus a little longer than the song I wanted to put in them. I did that.
1) I went into After Effects with the background of the menu I wanted to use.
2) It comes in as a .psd file.
3) I then stretched it out to a length a little longer than the song. (For exaample, I'm using a song that is 4 minutes and 50 seconds, so I stretched out the background of that menu to 5 Minutes.)
4) I then rendered out that newly made 5 minute menu out of After Effects, using H.264 1440 x 1080i, 29.97 High Quality.
5) I then brought that newly made 5 minute background back into Encore and placed it over the original 30 second background in Encore.
6) Now the song and the videos inside the "Video Drop Zones" will loop until the song is over, stop, then the song will start again and the videos keep on looping. Just like in DVD Studio Pro
For this particular job I did this 6 times (1 for each sub-menu) depending on the length of the song I am using for each menu.
1) The first sub-menu is a 5 minute menu which, when rendered in After Effects, came out to be 1.5 GB Big
2) The second menu is a 4 minute menu which came out to be 1.2 GB
3) The third is a 4 and a half minute menu which is 1.35 GB
4) The fourth is a 3 and a half minute menu which is 1.05 GB
5) The fifth menu is another 4 minute menu which is 1.2.GB
6) The sixth menu is a 7 minute menu which is 2.1 GB.
When you add them up it actually comes out to be 8.4 GB just the menus without any videos in them.
So Encore has already compressed them down a little.
It's not the videos that are taking up much space, but these menus.
Since I am building my job in Encore to a folder, I want to see what the actual size comes out to be after it's compressd. This will give me an idea of how big I can make my 2 and a half hour wedding. The Target and Max Bit rate.
I hope that sheds some light on why Encore is saying that the menus and QT files are taking up 7.1 GB already.
I wish there was another way that I can have my menus play for the length of any song without having to go into After Effects and stretch each menu to accomodate the length of a particular song. This takes up a lot of space, but it's the way I like to make my menus.
Thanks again

Changing bit rate, etc. on songs already in iTunes library

I've done this many times before, but I keep forgetting how, and I haven't found the HELP menu to be of help. Anyway, I have a recording that Id like to share, but its file is too large, so I have to reduce it by decreasing the bit rate. How do I do this?

iTunes: How to convert a song to a different file format - http://support.apple.com/kb/HT1550 - including information about different formats and discussion about compression.
Topic: Need to convert mp4 to mp3 - Zevoneer's post on converting songs - http://discussions.apple.com/message.jspa?messageID=9244740
This also applies to different bitrate with same format.

What are the Bit Rates of the Music Store and Podcasts?

What is the bit rate quality and format of a song downloaded in the Music Store? And podcasts? Are they perfect, Apple Lossless quality or what...?

This might be true, but you won't experience any improvement in sound quality. Here's some info on bit rates:
This was originally posted by the incredible Sparky the wUnderdog
"As a general principle, you can fit more CDs on your iPod if you encode at lower bitrates (making smaller files), but at the cost of audio quality. 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.
iTunes's MP3 encoder is so-so; the LAME encoder is better at preserving sound fidelity to the original. AAC files ripped in iTunes certainly sound better than its MP3s, with audio quality close to the best LAME MP3s 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 higher compression rates 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 & 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 > Edit > 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 MP3s, 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 AACs or Apple Lossless, but almost everything reads MP3s. So if you plan to burn CDs 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 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."

Converting Bit Rate of iTunes Purchased songs

I am in the process of converting all my music files to 112 bit to allow for mores space on my iPod. However, the songs I have gotten of iTunes through the music store are protected and it won't allow me to convert them . My method of converting the songs is to select them in itunes and then go to the pulldown menu "Advanced" and then to select "Convert Selection to AAC" and subsiqently convert the bit rate. Is there any way to convert the "protected" songs to a smaller bit rate?
Thank you for your help.

Robert
Short of burning the track to a cd and then re-ripping them at the lower bitrate, no, there is no way to reduce the sound quality of your purchased music.

Bit rate for all computer?

Hi all,
I'm burning a DVD in DVDSP 4, I burned and tried it in my MacBook Pro and on normal DVD player and It works perfect, the problem comes when I play it on some not so new PCs, in one of them the buttons (text and silver frame) in the menu seem to repeat in different positions, and in the other computer it plays fine but the audio doesn't work and sounds kind of static... does it have something to do with the encoding bit rate in DVDSP? maybe in Compressor??
HDV material / compressed with DVD best 90
SD DVD/PAL
Bit rate in DVDSP 5.0 Mbps
Max Bit rate 6.2
Appreciate your help!
Javier

Which Windows program was used to play the DVDs? Hopefully not Windows Media Player.

How can edit the Bit Rate on my music?

I have downloaded some lectures that are below 128 Bit Rate, so they are not being uploaded onto iTunes Match.
I was told to change the Bit Rate to 128, and that would solve the problem.
How do I do that????

Thank you Airsculpture- I have gone into the menu bar on iTunes, but I can'rt seem to find the location where to choose or select a highter Biz Rate. Can you give me a little more guidance please?
Limnos- I understand it will not improve the quality. I just need to increase the Biz Rate so it is accepted on iTunes Match. Any Biz rate lower than 128, will not be accepted.

Changing bit rate from 128 to 192

I'm getting shure e4 headphones and want to experience the full potential of its sound, so i want to change the bit rate from standard 128 to 192. Can anyone give me directions on how to do this? also can you adjust bit rate to higher than 192?

You don't say which file format you are using but regardless, this is how to change your Import settings. Open iTunes go to iTunes>Preferences>Advanced>Importing. Once there, from the "Import Using" menu pick the encoder you want to use and below that from "Setting" choose "Custom" and in the box that appears choose the bit rate you want. Both MP3 and AAC formats will let you choose up to a bit rate of 320 kbps
