Stephen Sondheim wrote a NEW song for the film adaptation to be sung by Meryl Streep.
It was then taken out of the film due to pace and context in contrast to the entire film.
The special feature on the bluray includes this with an introduction by director Rob Marshall.
! WARNING !
Because this is from a special feature, the quality doesn't have to be the same quality as the movie itself.
In this case, the video and audio do not match the quality of the movie.
The video in this isn't that great or detailed, compared to the movie. But, it's decent enough to have and watch.
Just because you hit play and watch it on any screen and say "it looks fine to me", doesn't mean that it's great.
It's actually lower quality when compared to the actual movie.
And it's not me doing anything to reduce quality. I encode video to be transparent to the source without applying filters. I treat video as I do audio.
It just isn't there.
The audio is lossy AC3@320kbps in stereo only.
A valid but rarely used bitrate.
Blu-rays can have lossless audio formats like: DTS-HD Master Audio, Dolby TrueHD, or LPCM. But, not always.
They don't need to spend much time or effort into mastering special features. It's entirely optional to dedicated time to featurettes.
And they didn't make a "director's cut/extended/uncut" version of the movie which would have this deleted music number inserted back into the film.
So the quality is dropped and done quickly just to get it on the disc.
To trim for just the music part of the special feature, I demuxed the special feature with eac3to, then indexed the h264 elementary stream with DGdecNV and used Avspmod to look for a valid area to start a new trim.
I used FFMPEG to convert the AC3 to a 64-floating point WAV file and opened in Sony Sound Forge and made cross-references to find a stuitable start point for the new trim.
Once I found the new starting point, I applied a trim to both the video and audio.
The video, I used avisynth to trim and resize to 720p and encoded with x264 using placebo settings. The picture quality is transparent to the original 1080p source.
The audio, I used "delaycut" to losslessly (in this context = "no transcoding") to cut the original AC3 file to a new AC3 file but starting at the new start point.
I used the 64fp WAV to create AAC versions for anyone who doesn't want AC3.
]NO MP3'S ALLOWED!
Get used to the idea of this technology. It's bad enough I transcoded from AC3 to AAC. Both lossy formats.
AAC is more advanced than MP3, so you shouldn't hear much of a quality loss.
If someone wants MP3, download the AC3 yourself and find a program to conver to MP3.
And don't even think about sharing an MP3 in this thread. :mad:
Lossless -> lossy = some loss.
Lossy -> lossy = more loss.
MP3, AAC, and AC3 are all lossy formats. Lossy formats don't have a bit depth. It's neither 16-bit nor 24-bit integers (nor floating points).
It will use any bit depth it needs per sample.
Any software that tells you that lossy formats have a bit depth is either:
A) reading what the source file used to be before converting to lossy format
B) being stupid and just using any bit depth to keep stupid people from asking
C) is just stupid software by stupid developers made for stupid people
Codecs will decode at whatever you set it to, if you have control.
If there is no control over the codec, then it's usually decoded at a fixed bit depth.
In FFDShow, you can manually choose between 16/24/32 integer (fixed point) or 32 floating point.
For live playback, decoders (typially) don't allow 64 floating point (that should be evident enough how useless it is for simple processing).
Transcoding between each format causes a loss in quality.
To reduce that loss as much as possible, I used FFMPEG to create a 64 floating point WAV.
64fp is the highest WAV format you can have. It works with insane amount of fractional numbers so the errors produced when programs round off to nearest decimal or integer value, are greatly reduced when using 64fp.
You can probably work with 32 floating point and there won't be a difference, at all.
I encoded the video to 720p. Since 1080p would be useless as there's no details beyond 720p.
The file size may seem small, but I used the best settings to keep it from losing a lot of quality.
Size ≠ quality :smrt:
It didn't require much bitrate with the settings I chose and at a CRF (Constant Rate Factor) of 16.
(0 = lossless, 1 = extremely high quality, 51=lowest quality on earth)
Since it decided it required less bitrate, that's also evident there isn't much details in the video itself. If there was more grain in the video and more colors and sharpness, the CRF mode would calculate it to require more bitrate. :smrt:

No lossless formats, since it's low quality audio to begin with. Converting to FLAC/ALAC won't do a single thing.
AC3 was cut without any loss of quality using "delaycut" software.
AC3 can be played in Foobar2000, MPC-HC and VLC with proper codecs.
AC3 is not iTunes or MAC friendly, so the AAC was carefully created.
AAC is also better than MP3 so there is no need for an MP3 version.
