NOTE: 272p = frame-size 480x272 pixels, 16:9 aspect ratio, playable on all kinds
of MP4 capable devices/players/playback systems
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 1280x544
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 - CoreCodec for H264 and part of DivX7
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 CoreCodec
(I have an ATI card, just in case you were wondering).
Problems one can have may come from either one of the following
and/or a combination of these Ã¢â‚¬â€œ 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 Ã¢â‚¬ËœblockinessÃ¢â‚¬â„¢ 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
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).
I encode H264 for six years and I have experienced (first-hand) any problem
one might have or imagine. I have heard almost every Ã¢â‚¬ËœcomplaintÃ¢â‚¬â„¢ out there
and would, if asked POLITELY, be happy to answer questions and give as much
help as humanly possible
I always have.
One man stated just recently
">>>...... at 2010-05-26 17:04 CET:
...your 720p format is unique - For some reason no one seems to think
doing it, which is why people go into spastic attack in your comments. "
"...the quality is much higher than ANY other 350mb rip."
Please Others, don't go "spastic" - just go away instead spreading Insanity
We have enough of that. On TPB alone every single title is usually
available in many torrents.
Nobody forced you to use mine, right?
But maybe.... no.... anyway, I'll ask "Who was that?"
