lame 3.99 V2 VBR files are consuming allot of my ipod space

some files end up being 10 MB, I only have 350 songs and it's 2.15GB

To me, that's unacceptable, and I need a solution...

i have quicktime *dont know which setting to use of vbr, compress it in quicktime movie format then export in mp4 container, or compress it directly in LC format*

The thing is, when compressing in mp4 lc format *Directly, instead of using it as a container*, the songs are still vbr, it makes no sense to me?Because in the same area there's an option for AAC LC-VBR *which for some reason i can never pick*

So, what it seems is export to movie format, then mpeg4 container is low quality vbr, and regular exportation with mpeg4 instead of using it as a container is high quality vbr...but then, what's the purpose of mpeg4 AAC-LC VBR that is greyed out and i cant choose




So, I'd like a solution, I'd like ANY efficient encoder that won't fill up my ipod touch so quick like that, basically, I want the perfect encoder and encoding settings...

also, my battery drains pretty fast, im wondering if it has anything to do with the encoder?

Many people are happy with lame -V 4 or even -V 5. That could save you a lot of space.

Is that the best?if you could direct me to the best quality/size efficient encoder, paid or free, direct me to it please

LAME 3.99 is a alpha build and i wouldn't recommend using 3.99 while it's still in devlopment. I wouldn't be suprised if LAME 3.99 produces very large bitrates at V2 just like LAME 4 alpha does, which seems to be abandoned.

V2 - V0 VBR can produce very large bitrates due the sfb21 limition on the Mp3 specs, which casuses bloated VBR Mp3 with music that contains high freqs such as Metal and Rock. Using the -Y switch which enabled by default at -V3 and below, but it greatly reduce the bitrate if used on -V0 - -V2.

Since you got a iPod, you could use Nero AAC. Which can reach transparency at -q 0.50 (175kbps) to most people's ears.

Also the battery problems might be the battery itself or the firmware. My iPod Classic battery drains more quickly ever since i updated it to 1.3  .

I agree.  No need to use QuickTime Pro for encoding on Windows as that is a long and terrible process (unless you use the new tool that is talked about in the 2010 listening test thread).  Might as well just stick to using Lame 3.98 (don't use 3.99, it isn't archive ready) at a lower setting.

Edit: No need to pay for something when both Nero AAC and Lame mp3 are free and offer high quality.  Instead of just asking blanket statements and hoping that something sticks, I suggest you search the forums.  Many topics have been brought up asking for the best lossy encoding solution.  Read through those, read through the hydrogenaudio wiki, and go from there.  That way you will know information without us having to answer questions asking about encoder, bitrate, and other basic information.  Then I suggest that you conduct a series of blind ABX tests to determine what works for you.  We don't have your music, your ears, or your equipment.  Only you can answer questions about audio quality for yourself.

And important questions is:  Are you re-compressing your mp3s to try to make them smaller or ripping your CDs again?  (Or compressing your .flac files again?)

From what I'm getting, I'm going to re-do my collection in 128VBR best recommended quality, export in mov then mpeg4 container..*since that's the only option exporting to vbr with .mov format*

BUT...from what i get, i have a question






I took that image myself, see AAC-LC VBR Music?Yes, how do I access that?It is always greyed out, I have quicktime pro, what am I not doing correctly?

Also, see AAC-LC music?When i compress in that, it ALSO seems to have VBR qualities to it, as the bitrate is never constant...

So my question, is what's the difference between these three techniques, and which is the best?

Because the question was originally about LAME encoded files...  Looks like it shifted from that pretty quickly though.

Yeah, that's what I was thinking.  In case the OP was annoyed with the mp3 vs aac debate (based on the post icon and the gratuitous submission of the same image), I split it off over here:

I understand that the whole debate brought up by someone else made things a little confusing but you don't want to use QuickTime pro for AAC encoding on Windows.  Why?  It sucks.  You have to export each file as a MOV file, open that MOV file in QuickTime pro, and create an mpeg-4 file (it will have an *.mp4 extension) by passing the audio through.  The process takes about 3-4 minutes per song and you will lose track tag information.  So don't even bother especially when there are other programs and encoders that, to me, provide the same quality but a better experience.  There is a new command line tool that allows you to use QuickTime for VBR AAC encoding but the resulting files aren't gapless.

Long story short; I think you would be better off either trying a lower Lame setting or using Nero AAC if you insist on using AAC.  No need to post the same picture again.  We fully understood your original question and gave you answers.  Things might have been lost by that tangent topic that was brought up by someone else.

Edit: Just in case you really wanted to know how to output true VBR AAC files with QuickTime (this is for version 7.6.5), I have come up with a procedure.
1.  Open QuickTime pro.
2.  Open your source lossless file (it must be a format that is compatible with QuickTime)
3.  Click on File and then click on Export
4.  Next to Export:, you need to pick Movie to QuickTime Movie
5.  Click on Options
6.  Click on Settings under Sound
7.  Choose AAC as the Format:
8.  Put a check mark in the "Show Advanced Settings" option
9.  You can then change the Encoding Strategy: to variable bitrate and constrained variable bitrate.  However, when choosing variable bitrate, you can no longer adjust the quality (at least I can't).  You can just use the recommended settings.
10.  Click OK when you are done and then save the MOV file to a directory of your choosing (remember where it is).  The encoding process may take a while.  It took about 2 minutes and 30 seconds to encode a 5:48 source ALAC file of mine.
11.  Now you will want to click on File and then Open File.
12.  Find where you stored that MOV file and open it.
13.  Click on File and then Export once the MOV file is opened in QuickTime.
14.  Change the Export: option to Movie to mpeg-4
15.  Click on the Options button
16.  I choose MP4 as the File Format:, I am not sure if changing it to MP4 (ISMA) makes a difference or not.
17.  Video should be selected first.
18.  Make sure that the Video Format: is set to none.
19.  Change the selection from Video to Audio.
20.  Change the Audio Format: to pass-through.
21.  Click OK and then click on Save
22.  This process should only take a few seconds.  You will have to find the mp4 file and change its extension from *.mp4 to *.m4a in order for iTunes and your iPod to properly recognize it as mpeg-4 AAC audio.  Now you will see that the track tags have been thrown away thus making the whole 5 minute process rather pointless as you will have to take the additional few minutes to correct the tags.

That is the complete procedure.  It produces file that have bitrates around 128kbps VBR.  My resulting file had an overall average bitrate of 136kbps.  Using the 128kbps VBR_constrained setting in iTunes resulted in an overall average bitrate of 138kbps.  So you may want to just use iTunes for AAC encoding since it gives you more options.  Either that or Nero AAC.  I still think you would be better off trying Lame mp3 at -V 5, Nero AAC at -q0.4, and iTunes AAC at 128kbps VBR (this is constrained VBR).  Fire up foobar2000 and conduct a series of blind ABX tests to determine which encoder and setting is right for you.  I think you will be surprised by your blind ABX test results.  I know that I was a few years back when Lame 3.97 was finalized and I conducted a series of blind ABX tests.

If you have the original FLAC files, then you don't need to worry about "archive quality" on your lossy encodes for iPod listening. So, your goal should be to choose an encoder and encoding settings as low-bitrate as you can before you start noticing artifacts of lossy encoding. Odds are pretty high, especially for most portable listening, that you'll be fine with Lame -V3, -V4 or even -V5. Or with Nero AAC (I'm not familiar with Nero AAC settings so can't comment here, but I understand it's pretty good and at least competes with LAME for transparency at different bitrates, and may exceed LAME).
