Jaws.1975.HDTV.480p.H264

*** Video is H264; audio is AAC LC and container is MP4. ***

NOTE: [lepton] family = frame-size 368/416x-2 (AR) pixels, 16:9 or 2.35 aspect ratio
ONLY on PC/PS3/Xbox/standalone mp4 capable players.
NOT Handhelds/iPod/PSP/Zune/clones compatible file, however,
some portables accept these format (TIP: upgrade firmware).
272p = frame-size 480x272 pixels, 16:9 aspect ratio, playable on all kinds
of MP4 capable devices/players/playback systems (CURRENTLY "ON HOLD")
320p = frame-size 576x320 pixels, 16:9 aspect ratio, or 576x240 for 2.35:1
(movies/theatrical AR)middle-format, playback
ONLY on PC/PS3/Xbox/standalone mp4 capable players.
NOT Handhelds/iPod/PSP/Zune/clones compatible file, however,
some portables accept these format (TIP: upgrade firmware).
352p = frame-size 624x352 pixels, 16:9 aspect ratio, middle-format, playback
ONLY on PC/PS3/Xbox/standalone mp4 capable players.
NOT Handhelds/iPod/PSP/Zune/clones compatible file, however,
some portables accept these format (TIP: upgrade firmware).
360p = frame-size 640x360 pixels, 16:9 aspect ratio, middle-format, playback
as for 272p (except streaming)
480p = frame-size 720x480 pixels for 16:9 aspect ratio (TV) or 720x304
for 2.35:1 (movies/theatrical AR)
720p = frame-size 1280x720 pixels for 16:9 aspect ratio (TV) or 1280x528-544
for 2.35:1 (movies/theatrical AR), hardware intensive

Most problems people have are with frame-sizes 1280x720 (720p). I recommend
and have used one system for years - CoreAVC for H264

("Deblocking" set to "Standard") and part of DivX7-8 for AAC - AAC DirectShow
filter.
Both are proved perfect, fastest and provide seamless playback up to 1080p
on new generation of computers. Newer NVIDIA graphic cards processors (GPU)
decode H264 using dedicated subroutines directly served from CoreAVC
(I have an ATI card, just in case you were wondering).

New DivX8 is maybe 18% slower than Core AVC and very common,
and in order to use DivX8 H264 and AAC DS filters outside DivX7 or 8 player
(as in Windows Media Player or Media Player Classic), Haali spliter
must be installed. Beware, however, that video quality could be very much
degraded on encodings where extremely low bit-rates have been used.
TIP: Switch back and forth between Core AVC and DivX H264 DS filters by marking
and un-marking Core AVC "Preferred decoder" setting.

Problems one can have may come from either one of the following
and/or a combination of these ΓΓé¼ΓÇ£ the playback system itself, a
malfunctioning device or lack of knowledge.

For instance, any so called "jerky" playback of "system-heavy" 720p comes
from insufficient CPU and graphic engine power or simply - overloaded
computer. Use of ddshow filters and "codecs" is suicidal. This is not
Russian 720p Matroska format ("official" 720p) and completely different
setup is required (extremely high bit-rates of .mkv 720p to some extent
"hide" bad encoding style). In low bit-rate H264, such as mine,
those errors and bad technique cannot be hidden and therefore are avoided as
much as possible.

Any 'blurriness' of video comes from less-than-recommended media player.
VLC and a few other players are the most versatile and, generally speaking,
good - but quality is 10-20% lower.
Any ΓΓé¼╦£blockinessΓΓé¼Γäó comes from 'system-too-slow' situation, when decoding
engine of ones device become over-capacitated and cannot process all frames
as it supposed to.
On "I have no video" and "I have no sound" I don't waste my time as this
is generally a complete lack of knowledge and/or understanding.
RTFM is the best response I can give.

MP4 is absolutely ISO 14496-1 compliant. There are no B-frames, no CABAC
entropy in 272p and 360p, no strange filtering and no AV weirdness of
any kind.

Recommended resolution for computers is 1024x768 (no matter frame-size).
PS3 + HDMI cable + newer TV have been reported as best combination.
I am very proud on sound quality and hence I recommend use of stereo system
and proper loudspeakers (connect Line Out of Soundcard or standalones
with Line In of any Stereo rack).
