Anamorphic encoding in matroska 720 x 432 with AAC 5.1
Hi,
i decided to upload a nice matroska test sample, trying to show the advantages of anamorphic encodings. Please, if you are not interested in this subject at all, dont download the file, i guess my provider will kill me if the bandwidth i expect will become reality ( the sample has about 10 MB ). Here the Link ( use 'save target as' and "StarwarsAAC5_1anamorphicXviD.mkv" as file name, including the ", to get the correct extension ) and the details : Video : Res : 720 x 432 , anamorphic ; Output res on playback : 720 x 304 ( 1:2.35 ) Codec : XviD 2 pass ( I like both, DivX5 and XviD ) Settings : Bitrate 1250 kbps, VHQ 4, 5 B-frames, packed bitstream, QPEL, h.263 quant Framerate : 25 fps ( PAL source 720 x 576 ) Audio : AAC 5.1, 220 kbps, 44.1 KHz, PsyTel aacenc 2.15 Note : sound quality sucks, there is still a bug in this old version of aaceenc.exe, but the new NeroDigital AAC pluginwas released today, and it should give nice results Total : 2 x 700 MB ( No subs yet, i was too lazy to rip them ), but it wouldnt add much How to make it : 1. Encode Movie in 2-pass using VirtualdubMod, into AVI or MKV ( doesnt matter ). The important thing here that is different from making a 'normal' rip, is that you dont use any resizing, you just crop the picture ( either in AVISynth/Gknot or in VdubMod directly ). Make sure that the final encoding resolution will follow the multiples of 8 rule. This may make it necessary to crop 2 - 3 lines into the picture on top and bottom ( worst case ), but with > 400 lines in total you wont notice that, i promise 2. Add the original AC3 to the streams list in VdubMod, mark the start and end frame and mux it into another MKV 3. Demux the AC3 from this new MKV 4. Feed the AC3 into BeSweet with the -6chwav switch, normal azid settings 5. Feed this WAV into aacenc.exe ( ver 2.15 ), with the follwing CLI : E:\FlaskDivX\AACencoder\aacenc.exe -br 220 -if E:\FlaskDivX\AACencoder\starwars.wav 6. Download latest mkvtoolnix from Mosu's site, search for the win32 binaries of it ( cmpiled with cygwin ): Direct link for 0.4.2 : http://www.bunkus.org/videotools/mkv...lnix-0.4.2.zip 7. Use the following CLI : E:\FlaskDivX\mkvtoolnix\mkvmerge.exe -o testAR.mkv --aspect-ratio 2.35 testnosound.mkv starwars.aac If you'r not a CLI expert ( like i am ), simply copy mkvtoolnix and the sound.aac and the video.mkv into the c:\ root directory ... For playback : 1. Download the Core Media Player from Corecoded.com . This is not mandatory, as you may do the resizing in other players also manually. Then goto 'settings' 'audio settings' and disable the Equalizer ( tickbox ) 2. get the latest alpha matroska CDL plugin and install it . Note this is highly experimental !! 3. Download and install the newest matroska DirectShow parser ( 0.4.2 ) from http://www.matroska.org/announce.html 4. get the binaries of CoreAAC, the 5.1 capable AAC DirectShow filter, from Rarewares, courtesy to rjamorim 5. If you dont have a 5.1 setup ( like me ), you will need the great channel downmixer filter from trombettworks, or you cant hear sound Tell me what you think guys !! . I plan to upload another sample file soon, being the same file with exactly same settings, but resized to 720 x 304 and with MPEG quant, for comparison.

Sounds cool, i'll download it and have a look (tomorrow), but what you say about the aacaudio is something about which i just posted in the audio-forum: Do you really get improved quality at the same bitrate compared to AC3?

For a typical 2 CD rip i'd probably go for the original AC3, but this is a long movie and the AC3 bitrate is 448 kbps, so this will result in a 450 MB audio file ...
menno an Ivan from Nero are promising the new NeroDigital AAC encoder plugin will sound undistinguishable from the AC3 at > 240 kbps, and 160 kbps is possible with very good results ... |

The great thing about anmorphic resizeing is not to resize from 720 x 432 to 720 x 304 but to resize to 1024 x 432. See this way you get a lot more resolution and just a little loss in quality.
doing it the other way (making the video smaller) is useless you wouldn't get any adventage of anamorphic. |

Bah, we already have a bad reputation so we don't need to care anymore about that
It seems your problem are due to TCMP, not the CDL itself. Also I'm not aware of any problem with our DSF under W98 now (any different than on W2K/XP). It's just sad that W98 has no built-in support for Unicode. |

We will, with no doubt, be the first container to support MPC as I'm helping Frank Klemm on it, he is somehow part of Matroska (a major contributor to the format) and will rely on matroska for everything non codec related.
But everything starting from SV8 is begin rewritten from scratch with a lot of C++. Don't expect anything before a few months. |

Christion didn't resize to 720x304, he just cropped the black bars and set the aspect ration. The final res depends on the screen resolution when you watch it, so that'd be 1024x432, or 1520x641 in my case. All the resizing is done during playback. Quote:

About some links in the first post:
1) mkvtoolnix-0.4.1.zip is not available, when clicking on that link. I found one here: http://www.bunkus.org/videotools/mkvtoolnix/win32/. 2) Download and install the newest matroska DirectShow parser ( 0.4.2 ) from http://www.matroska.org/anounce.html. Better change that into .../announce.html. Last edited by Wilbert; 2nd June 2003 at 12:45. |

Important info:
Get the latest coreaac filter version here (compiled by john33)! the one on rarewares is already out-of-date btw: couldnt be the function of Trombettworks' ChannelDownmixer included in CoreAAC to make it automatically work on non 5.1 setups? would make it perfect...
