Title: File Structure Standardization
Post by: FrostWraith on March 05, 2007, 02:35 PM
I was just wondering how everyone stores their music and movies these days, like what file format, ripped at what bitrate?

I currently have all music at mp3 and movies at mpg/mpeg.  What does everyone else do and what structures do you see being used in the future?

I like FLAC@192kbps, but it's hard to come by.  mp3@192 is fine, though 128 is more common.  Videos are typically mpg3 or avi.

I'm an OGG Vorbis fan, myself. 192 bitrate minimum. Videos in OGM or MKV format.

I bet it's hard to come by, since FLAC doesn't specify bit rates.

Shh.  I see torrents with FLAC and a bitrate all the time.

FLAC, by nature, is lossless and no bitrate.

One look at my music torrent site, and any FLAC upload I see is file/FLAC/Lossless.

mp3 at 192kbps is more common than 128, as 128 is not very good at all.  The minimum for uploads to the above mentioned private site is 192kbps.

If size of the mp3's is at all a problem, don't forget that.  Bitrate increases in mp3 and other file formats will affect their size.
7 tracks at 320kbps is 100mb.
7 tracks in FLAC is ~303mb
and so on.

192kbps is what you would aim for, and if you're an audiophile aspire for 320kbps.  Use Lame 3.97 with the V0 switch for encoding.  Always keep your .log if you use FLAC.

Videos in x264 are rising in popularity, however I prefer videos in the XviD codec.  It's compatible with my portable video player.  XviD is also the popular codec for release groups.  You'd be pretty safe in reading scene rules and keeping those as your personal guidelines.

That and FLAC@192kbps is fucking useless. FLAC is at 700-1440 normally.... :/

Really?  Shows how much I know about FLAC :\

FLAC is a lossless format, like WAV, but with good file compression. http://en.wikipedia.org/wiki/FLAC

QuoteFLAC is for efficient packing of audio data, unlike general lossless algorithms such as ZIP and gzip. While ZIP may compress a CD-quality audio file by 10–20%, FLAC achieves compression rates of 30–50% for most music, with significantly greater compression for voice recordings.

Lossy codecs can achieve ratios of 80% or more by discarding data from the original stream. FLAC uses linear prediction to convert the audio samples to a series of small, uncorrelated numbers (known as the residual), which are stored efficiently using Golomb-Rice coding. It also uses run-length encoding for blocks of identical samples, such as silent passages. The technical strengths of FLAC compared to other lossless codecs lie in its ability to be streamed and in a fast decode time, which is independent of compression level.
