.flv codec for ipod

<< < (2/2)

Llorean:
FLV means "Flash Video" and is a video format.

Audio is muxed in, most often in MP3 format. If you converted your MP3s to FLV, it probably simply converted them to a lower bitrate MP3, then wasted space putting them in the FLV stream.

On my desktop, I converted my .mp3 songs to .flv. I dont want the mp3 format.

FLV uses MP3 compression.  If you don't want MP3, use Ogg.  As it stands you've simply taken an MP3 and wrapped it in an FLV container.

And you can, provided you remove them from the FLV container first.

Your right!

I just used a general mp3 converter to to convert to a lower bit rate, and I got the smaller file I was looking for!

This is great cause now I can store 2-3 times the number of songs on my ipod (and i cant hear the difference with my headphones).

How simple!
Thanks guys! your the best...

bluebrother:
you could also use other formats like ogg, which usually gives smaller files at a comparable sound quality. This of course depends on what quality you want to have ;)
(just as a number, I usually have ogg files encoded with -q5 which results to an average of 160kbit, which is similar (IMO) to 192kbit mp3)

Rincewind:
People at Hydrogenaudio forums have made a few listening tests and found out that with inexpensive headphones a bitrate of ~130 vbr with modern codecs is hard to distinguish from the original.
The difference between ogg, mp3 (lame) and other formats at the same bitrate was very small.
With better phones and a good ear, 160kbps (like bluebrother suggested) seems like a good idea.

If you chose mp3, I strongly suggest to rip your music with a vbr setting and joint stereo (v3 = ~170kbs for me, v6 should get you a bitrate of 120 on average).

But since you are transcoding, this doesn't matter much anyway, qualitywise.
