NOTES ON 50 FPS:

The source of this encode is the so-called "Norwegian
Edition" BluRay, which was released worldwide.
Specifically, the source used is the PAL (Europe) version
of this release edition (there is also an NTSC (America)
version of the "Norwegian Edition" BluRay boxset). This
edition is a 50 fps interlaced release stored on disc as
a two-field top-first 25 fps video stream.

Not all scenes were recorded or possible to remaster in
50 fps. Notably, all studio scenes are 50 fps, while most
of the scenes recorded outside the studio are 25 fps.
This is noticeable in the encode, although it is due to
the BluRay being made this way, and is intentional. The
extra frames added to convert the source video from 25 to
50 fps in this torrent release were added as part of the
deinterlacing process and not by means of AI smoothing or
framerate enhancing software. This means that the encode
is still authentic and true to source, and also results
in not all segments of the episodes being high-framerate
as explained above.

NOTES ON AUDIO:

The audio on the discs are stored as a stereo stream.
However, this is "fake" stereo; the left and right
channels are equal, and they have been downmixed to mono
in this release for your convenience and a better end
result.

All Paarthurnax torrents are encoded in the AV1 video and
Opus audio codecs. This is a modern codec that offers the
best possible compression at any given quality level. Not
all media players support this format. If in doubt: VLC!

AV1-encoded files are usually around 30% smaller than
HEVC x265, and 50% smaller than AVC x264, at the same
quality.

The table above shows quality at mean, 75th, 25th and 1st
percentiles of frames, using Netflix's VMAF perceived
quality algorithm. Improvement above 93 is considered
imperceptible for film contents. All of our torrents
target a mean VMAF around 94 and 25th percentile no lower
than 91. This can be done while maintaining as small of a
file size as possible by splitting the video and encoding
the segments at a quality that is perfectly optimized for
each individual segment.
