How do I reduce the bit rate for existing songs

Some of the songs are too large. How can I reduce the file size of selected songs? Thanks.

Hi,
You can do it by converting your file either with a lower bit rate or using an another compression algorithm. Be aware taugh that by doing so, you will loss audio quality. The best way is to restart, if possible, from your original files with your new importing settings.
To change your importing settings, go in the iTunes preferences, in the Advanced tab and then in the Importing tab and set the compressing algortihm and bit rate. AAC encoder is the algorith that will gives you the better compressing ratio.
Then, you you can either chose to reimport from your original CD (iTunes will ask you to replace the previously imported files) or select from the advanced menu the converting selection.

How can I reduce the bit rate of songs in my Music Library to enable me to

At the moment i can only fit about 1300 songs on my iphone and also have used up half the space on my 120gb Classic with 7000 songs which is a lot less than what i was told would fit on. so............
How can I reduce the bit rate of songs in my Music Library to enable me to fit more songs onto my iPhone or iPod Classic.. and what is the minimum rate that i should stick to in order to retain good sound quality.

For existing tracks, see:

For CDs you import in the future, change the Import settings in the iTunes -> General preferences.
As to what will be a good bit rate, that's going to be up to you and what quality you find acceptable, but many people find that 128 kbps AAC is the optimum balance between small file size and quality.

How do I change the bit rate for dls?? How times can I download one song??

I'm new to iTunes. I already downloaded 3 songs when I realized that the default bit rate is 128Kbps. I tried changing the bit rate to 192Kbps with a (Variable Bit Rate) checked.....unfortunately when I downloaded the next 2 songs the bit rate turned out to be the same.
Do I have to restart Windows or iTunes before downloading again?
And now that I have 5 songs with a lower br than I wanted... in order for me to have(download) the song at the higher bit rate...Is it possible to download one song more than once?
Thanx.

You have no choice as to bit rate when purchasing from the iTunes Music Store. The official bit rate of all tracks there is 128 kbps (a very few have been reported to be at higher rates, but that's not a choice you can make, it's how the track was encoded by the record company). The setting in the iTunes Importing preference is for tracks you import from CDs only and has no effect on iTMS purchases.
Is it possible to download one song more than once?
No. Except in extraordinary circumstances, the iTMS allows only one download per purchase.

How do I reduce the bit rate when listening to iTunes preview of songs ? It is eating up my bandwidth

I like to listen to music previews on my iphone before I decide to buy. But this is eating up my bandwidth. Even the previews are at 256 kbps. This is 4 times higher than Amazon which is 64 kbps. Is there any way to set my access to a lower bit rate, or adjust it to mono or anything ? The bandwidth cost is killing me. Thanks in advance.

How do I reduce the bit depth of images to 1-bit within Acrobat 9?

I am hoping a simple solution exists within Acrobat 9 for reducing the bit-depth of images to 1-bit.
I know of two methods that both seem more like workarounds. One, edit the image using Photoshop. Two, without Photoshop, export the page as a 1-bit PNG and recreate the page in Acrobat. It seems like one of the preflight fixups should be able to get it done with the right settings. But, it's a labyrinth of unfamiliarity.

There's no predefined 1-bit conversion in Preflight because it doesn't make sense. Preflight will not dither bitmaps, so most images will become black squares. Extreme color conversion is only intended for text/vector objects.
If you want to try it anyway, you can create a custom Fixup if you have a 1-bit ICC profile.
Preflight > Single Fixups
Options menu > Create new Preflight Fixup
Name it something like "Convert all to 1-bit BW"
Search for "Convert colors" in the type of fixup box and add it
Destination tab > Destination > your ICC profile for 1-bit black
Uncheck "use destination from Output Intent"
Keep everything else as default, though I'd suggest using "Embed as output intent for PDF/X" if you're making PDF/X documents
Conversion Settings tab > All Objects + Any Color (except spot) + Convert to destination + Use rendering intent
Press the + key to duplicate this step, and change the second copy to "Spot Color(s)"
Press + again and change the third copy to "Registration color"
Save the fixup and run it.
In case you don't have a 1-bit ICC profile installed, I've attached one.

Can I tweak the bit rate for iPod video?

I am starting to produce quite a bit of iPod video for podcasting. Some of our newer pieces are up to 2 hours long and I want to cut the bit rate back so that the files aren't so large. There does not seem to be a way to tweak the m4v parameters in Final Cut Pro or Quicktime Pro. I was able to make an mp4 video file with what a I wanted. It worked in iTunes but the iPod would not recognize it. Is there anyway to tweak the bitrate when making a video for iPod?

Is there anyway to tweak the bitrate when making a video for iPod?To exercise the greatest amount of control, use MPEG Streamclip (free). The MPEG-4 iPod presets can be user modified to limit data rates as desired.
I was able to make an mp4 video file with what a I wanted. It worked in iTunes but the iPod would not recognize it.The "Movie to MPEG-4" exports are limited to the 320 x 240 "Baseline" profile (up to v1.3).
There does not seem to be a way to tweak the m4v parameters in Final Cut Pro or Quicktime Pro.The "Movie to iPod" export is adaptively pre-set for maximum "LC" (640 x 480) and "Baseline" (320 x 240) data rates. There are no manual adjustments.

How do you know the bit rate of a video clip?

I have video clips from my video camera recorded in MPEG 2, PAL standard definition 720x576. 2 questions:
1. How can I find out what bit rate the video is recorded at?
2. Knowing this, can I in PProCS4 encode this for DVD without any transcoding (assuming, of course, no effects or fades etc have been added)?
I like to keep the coding the same, to avoid the quality loss of transcoding to a different bit rate.
I use 256 kb/s audio in MPEG 1 layer 2 (pretty much standard DVD format).
Any info appreciated.

In Ulead Mediastudio Pro, you can see the data rate of the video, and also in DVD Movie Factory select "do not convert..." etc, where un-edited clips are not transcoded, to give maximum picture quality. I dropped MSP, as Corel (having taken over Ulead) has, sadly' dropped the product, so I bought PProCS4 hoping it would be at least as capable. Alas. Having said that, in most respects PPro is as good or better than MSP, and runs fine on Vista and Win7 beta (which I am using now), so I am still happy I get PPro.

What is the bit rate for the songs streaming on iTunes Radio?

Is it 256kbps AAC file?

I have to agree with you. There are several forum discussions on bit rate being as high as 256 kbps but I don't see how it could be more than 96 kbps based on the poor sound quality I'm hearing. I'm comparing it to an internet radio station that is 128 kbps and sounds much better.
Am I missing something?

How can I reduce the storage needs for iMovie events (raw video)

Good news - After borrowing an 8mm analog camcorder (mine died years ago) and an older digital camcorder (mine doesn't support A/V in) I have been able to set up a "bridge" to convert our old 8mm home videos to digital and import them to iMovie.
Bad news - At 13GB per 8mm tape, plus the Mini DV tapes we also have, getting it all in the computer with room to grow is going to require at least 500GB of space, which I don't have. On hand are 120GB internal (MacBook), 120GB external (Time Machine) and 40GB portable.
After my experience with the 8mm analog camcorder (it died, couldn't buy them anymore, tapes useless) I want to get everything digital in a standard format with backup.
1) Is there any way to reduce the storage space required for the raw video (Events) without impacting image quality (already mediocre in the tapes converted from analog)?
2) What's the best way to squeeze an hour of video down to fit on a DVD but still leave the video available for re-import/editing in the future? I'd likely mail the DVDs to my parents house or something to keep them separate.
Thanks!

Hi
You can also use
Yousendit (google it)
where You can send 200Mb movies
- You download Your movie to them
- get an Internet address back ( url - I think it's called )
- this You copy and send in Your e-mail to those that want's Your movie
- and now they can get it from same address
If You pay You can send up to 2Gb (if I remember right)
BUT it will take time ! In most of my cases - burn it onto a DVD and send by snail-mail most often are a better solution.

How can we reduced the patch time for u6394500.drv

Hi,
This patch generally takes 14-15 hours to upgrade R12.0.4 , I want to If some body have pointers to reduce the patch applying time.
thanks in advance

You could try disabling archivelog mode while patching, and use 4 workers per CPU core that you have on the database server.
You can try using a staged appl_top approach, but that will not likely help much since 12-13 hours of that time is spent in the database portion.

How can I reduce the background music from a song when I'm trying to make a mashup in Garageband?

I'm creating a mashup between two songs (Titanium and Starships). Everything seems fine: I just need to cut out the background music for the Starships song. Does anybody know how to? Thanks!!

Extract the audio from the movie with either Quicktime Pro, iMovie or a 3rd party audio editor like Amadeus Pro and use it as the menu's audio.

How to determine the bit rate with button over video subtitles?

I have a project where I've got several questions that come up on the screen. The DVD is subtitled in 14 languages, so depending on the language chosen, it will show the question in the proper language along with navigation buttons to go to the next question or track.
The problem is this: I added several new questions that each have a black only video that runs about 1min with 14 subtitle tracks made from photoshop psds. When I try to build, it fails saying "bit rate too high." When I removed all but 5 of the subtitle tracks, then it would build. I came up with a workaround, but then hit the limit of 99 tracks, menus or stories on a DVD.
I went back and tried combining all 3 questions in to one slide, but now with more information on the psd, it will only allow 3 subtitle tracks before it reaches the max bit rate.
How does it determine the bit rate? What can I do to lower the rate? I tried compressing the video at the lowest bitrate, but it didn't' help. I tried changing the psds to much smaller jpg files, but it didn't change anything. If anyone has any suggestions, please let me know!
Thanks.

CS,
Almost all DVD SP Tracks should first be completely constructed in a Sequence in FCP, the markers placed there, and then everything encoded into a single Mpeg 2 clip with matching length audio (even if just low bit rate AC3 silent audio, as the case may be, because all Mpeg 2 clips in the Title domain should be accompanied by an audio stream), and then imported into DVD SP.
Lay your subtitles under that and see what happens.
Take care,

How can I reduce the file size of 3 videos?...

...without losing quality? These three videos are as follows in terms of size and length of the video:
1) 148MB 19minutes
2) 357MB 18minutes
3) 164MB 14minutes
I tried using a video converter to reduce the bit rate in order to reduce the size, which i know affects the quality, but that did not actually work to reduce the file size this time.
I thought perhaps i should ask my forum friends for help on this matter. How,if at all, can I get all three of these MOV's under 100mb or to a total of 300mb for all 3 and preserve quality? It has to be able to play on an ipad (MOV or MP4). Thanks for your help!

I think that the point that David was trying to make is that reducing the amount of information originally provided by a product or part of it in order to make it smaller will inevitably reduce the efficiency of the product itself.
However, you don't have access to the original masters? Then you might be after a good compromise, meaning a video that can display decent quality while playing at its original frame size (say on the web).
Does this mean that there is no real way to reduce the size without losing quality?
If your target is the web there is a way to reduce the file size and still make it look decent enough. Re-compression means loss of source information but video compression is an art on its own and can produce some amazing results!
Not without testing though.
Now back to my previous post, use Compressor to try to reduce the file size and compare the result quality. Trust your eyes and be honest with yourself.

Suggestions for bit rate for books on cd

Hi
I'm trying to clear some room on my ipod. Thus far I've been importing everything at 192. I'm hoping to reimport some of the books on cd that I've put on and would like some suggestions as to how low of a bit rate I can use without affecting sound quality too much (I tried 96 and really couldn't tell the difference).
Thanks
Evelyn

Hi, Evelyn.
For spoken word recordings, 32 kbps is generally considered an acceptable setting.
And, for what it's worth, that's the Bit Rate for Audiobooks purchased from the iTunes Store.
EDIT: You may also want to have a look at these suggestions: Link

HT204406 how do I download higher bit rate songs from itunes match to replace the lower bit rate I have on my itunes library?

I have itunes match and I have about 500 songs that were ripped at 128kbps. I have been tolf that I can replace them via itunes match to improve them to 256 or 320?
I have put them into a playlist in my itunes library and I want to know how I can upgrade their bit rate via itunes match. Can anyone help me?

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:
