DISCO | Calibración-Rendimiento | AVSForum | DVD | Rec.709

[JavierSA]

Acaba de salir la última versión, la 1.3, del que sin duda es el mejor disco de calibración para HDTV (ITU.709) que, por si esto fuese poco, tiene la virtud de ser gratuito. Aprovechando este lanzamiento aprovecho para abrir un hilo dedicado a una herramienta excepcional.

Está disponible en varios formatos, AVCHD grabable en un DVD y reproducible en la mayoría de los lestores BD modernos, HDMV para grabar en un BD-R ó BD-RE, HD DVD grabable en DVD y MP4 para reproductores que puedan leer ficheros.
Este disco desde la versión 1.2 dispone de patrones agrupados para HCFR o CALMan evitando tener que ir pasando manualmente las plantillas en caso de no utilizar el Soft adecuado como sucede al utilizar los DVD de GetGray con HCFR.

Por motivos de compatibilidad con distintos lectores BD, para la versión AVCHD han creado dos versiones distintas, la normal y la parcheada (Patched) que además incluye patrones adicionales. La diferencia principal entre una y otra es el software empleado para la creación del disco, en la página de AVSFroum han incluido una tabla de lectores y su compatibilidad con uno u otro disco.

Otras mejoras respecto a la version anterior son:

v1.3 Update Notes
PRIMARY CHANGE:
- H.264 video has been recoded with " --colorprim bt709 --transfer bt709 --colormatrix bt709" in x264 to flag the video. Prior releases were only flagged for Mpeg-2 used in the HD DVD.


VERSION CHANGES:
- New version called PATCHED introduced. This version is similar to the v1.2 AVCHD, but it retains all folders from the HDMV version to possibly add support for Denon and Magnavox players using DVD media.
- AVCHD version is now authored in the same manner as the v1.0 AVCHD. This change was made to support PowerDVD playback and to correct issues reported with some Samsung players.
- HDMV and PATCHED versions now include pop-up menus for an alternate way to navigate within sections.
- HDMV and PATCHED versions now loop back to restart the same video when you reach the end of a section. In HDMV or PATCHED when you chapter skip forward past the last chapter you will return to chapter 1.


CHANGES TO PATTERNS:
- A new "Backlight Comparison" pattern was added. Assuming a display gamma of 2.2, the left half is intended to be about 5% of 100% luminance and the right approximately 10% of 100% luminance. The actual percentage of 100% luminance will vary depending upon display gamma.
- The prior "Dynamic Brightness" pattern was revised to include a plus sign (+) in the middle of the screen for centering measurement equipment as requested. The pattern is now named "Dynamic and Center", and the pattern was chosen because it was already included in the ColorHCFR and CalMAN sections.
- Previous Misc. Patterns were split into "Section A" and "Section B" (does not apply to HD DVD)
- Prior "Resolution" section was renamed "Section C" (does not apply to HD DVD)
- Unflagged h.264 video is still included in a new Misc. Patterns video titled "Section E", and a similar flagged video is added in "Section D". (does not apply to HD DVD)
- The HDMV and PATCHED versions have added w6rz videos in Misc. Patterns "Section F" to "Section J" to look at motion, Y/C delay, and deinterlacing. These items were not added to other versions because the w6rz encode is Mpeg-2.


CURRENT AUTHORING:
AVCHD - Arcsoft TotalMedia Extreme
HDMV - Adobe Encore CS4
PATCHED - AVCHD-Patcher 1.06 modification of HDMV
HD DVD - MovieFactory 6 Plus
MP4 - MeGUI with x264

Por cierto, con la versión "normal" en el TMT no me salen algunas de las plantillas misceláneas, con la Patched sí. He tostado las dos a ver si funcionan igual en un BD de sobremesa.

Pues que cuando accedes a "Misc. Patterns" en el AVSHD normal te salen los grupos que van desde la A hasta la E pero si en lo haces en la versión Patched además tde los anteriores te salen los grupos de plantillas que van desde la F hasta la J añadiendo esto:

SECTION F – Pattern from w6rz titled “filmjudder”. The 23.976 frames per second progressive video bar advances 16 pixels per frame.
SECTION G – Pattern from w6rz titled “interlacejudder”. The 29.97 frames per second bar moves 16 pixels per frame, or 8 pixels per interlaced field.
SECTION H – Y/C delay pattern from w6rz. The middle row of bars has perfect Y/C alignment, while other rows are offset 1, 2 or 3 pixels in each direction. If the middle row looks to be aligned properly, you are in good shape. If one of the other rows seems better aligned, you are off by 1, 2 or 3 pixels.
SECTION I – The w6rz version of SMPTE 133. This is an interlaced pattern with 3:2 pulldown for comparing deinterlacing performance.
SECTION J – A pattern from w6rz titled “interlace”. The video shows a 1 on the first field and a 2 on the second field. On a display that is dropping a field from interlaced video, a missing number would indicate which field is being dropped.

Principales cambios/mejoras/modificaciones:

-"Version 2a Update Notes
GENERAL NOTES
- RELEASE PULLED FROM FIRST POST DUE TO "AVCHD" ISSUES ON PANASONIC PLAYERS.
- The current downloads do not include disc and sleeve logos. These will eventually be updated.
- Due to the number of changes, this release may include unintentional errors. Please report any mistakes you notice for correction.
- There may be future revisions for error corrections, or other minor changes, but active development of AVS HD 709 has ended. It is possible that future accommodations could be made, if at some point users wish to contribute interesting calibration-related items to the project.
- The Example For Windows Computers in the first post now shows how to check MD5 with ImgBurn.

PROJECT CHANGES
- Because of issues reported with Sendspace, the file hosting was changed for this release. Dropbox had been the initial choice, but we quickly found out that without a Pro account it was not a realistic option (http://www.dropbox.com/help/45). Currently we have chosen to go with the previously suggested Megaupload, and dr1394 has offered to mirror the downloads.
- HD Nation video was added to the AVCHD and HDMV versions, and it appears in the menu as HDTV Calibration. The MP4 version does not include the HD Nation video, but the first post has links to the online episodes. The AVC video is not compressible like the test patterns, which makes the related downloads much larger than the previous versions. While this project started primarily as a way to take measurements, many current users may be new to calibration. The HD Nation video has been included for some background on how to adjust basic user settings, because we thought they did a good job on the series. We have generally tried to avoid changing AVS HD 709 items shown in the video, but there will be a few differences, such as the look of the APL Clipping pattern and main menu. HD Nation Episode 58 had an issue with one of the cameras, as they addressed in Episode 59, so the segment on color controls shares the issue and overall does not look as good as the other video.
- Menu navigation has changed to use links along the top of the screen, which allows for quickly moving between areas without returning to the main menu.
- Popup menus are narrower, so they should allow more unobstructed area for center measurements. The unobstructed area is primarily intended for CalMAN measurements that would require popup menu navigation to supply the expected patterns. Popup menus for Grayscale sections now include links to go to the color patterns, so you can measure a grayscale and color run without returning to the previous menu. A quick jump feature has been added to the popup menus. Opening the popup menu and pressing left should return to chapter 1 for most sections. Opening the popup menu and pressing right will quick jump to different locations depending on the section, for example the right quick jump for CalMAN measurement sections will go to chapter 2.
- The AVCHD has been created from HDMV authoring. The Mpeg2 menus have been replaced by AVC video using BDedit and tsMuxeR. multiAVCHD Build 770 was used in the re-author mode for further conversion, and the output was modified to the minimal set of AVCHD folders offered by commercial products such as TotalMedia or PowerDirector. Mpeg2 video is not AVCHD compatible, so for example the w6rz patterns are still not included on the AVCHD version. Now that the authoring is shared, features like popup menus are included in the AVCHD version. Currently there are no known issues with this procedure for converting HDMV to be AVCHD compatible.
- The HD DVD version has been discontinued. Links to download the last HD DVD version and manual will be provided later in these notes.
- The HDMV version is now offered as a UDF 2.5 .iso file for burning. Based on available information, this should allow for burning the version to BD-RE, BD-R, or DVD media. DVDM now appears in the Blu-ray Players List to represent the option of burning HDMV to DVD media. Ideally the current AVCHD and HDMV versions will support all compatible players, but any unanticipated player compatibility issues related to authoring will be dealt with after the initial release.
- The MP4 version now includes individual files for each video pattern, which should make the MP4 easier to use.
- The previous PATCHED version has been discontinued at this time. After further investigation of prior player issues, and since the AVCHD now uses HDMV authoring, it did not make sense to continue offering an out-of-spec PATCHED version.
- The Patterns Manual has been changed to a single PDF that documents the HDMV version. Differences for the AVCHD and MP4 versions will be indicated either in the manual or in the notes for the downloads. The PDF now uses Microsoft true type Arial, Georgia, Trebuchet, and Verdana fonts, which should allow it to print correctly from more computers. The orientation has changed to landscape so that the chapters would fit more logically, and hopefully it will be easier to read on wide-screen monitors. The document was created in Word, and the PDF was exported with OpenOffice after turning off symbol bolding on page 15.
- All AVC video has been encoded using recent online information and x264 version.
- Image files were created using the current 2.5.2.0 version of ImgBurn.

PATTERN CHANGES
- AVC video test patterns have generally been adjusted to 5 minutes in length, in order to provide more time to use the patterns before they automatically change. Lengthening the video has increased the download and file sizes.
- Text was dimmed slightly on the Black Clipping pattern and the middle portion of the APL Clipping pattern. Reducing the brightness of the text may make the flashing bars easier to see on some high contrast displays. Some video decoders show a bit of flashing that was intensified if using darker text, so the current levels were a compromise between bright and dark text.
- APL Clipping was modified to move reference white and black to the horizontal center of the screen. The additional levels below white allow more range to see the flashing bars on displays that are clipping below white. The bright portion of APL Clipping now flashes to 248, instead of 254.
- Added notes to the Sharpness & Overscan pattern that the outside single pixel line indicates no overscan. Also included squares with vertical and horizontal lines on a darker gray to fit with the preference stated in the HD Nation video on sharpness.
- The previous Constant Height 2.35:1 pattern was renamed Front Projection. The outside edges of the horizontal aqua-blue lines is still 818 pixels for a 2.35:1 image height, and the inside edges of the horizontal aqua-blue lines is now 800 pixels for a 2.4:1 image height. The background of the pattern was changed to show squares and diagonal lines, and circles were added to the center. The image changes were made to provide additional ways to check geometry for front projection setup.
- Grayscale from 5% to 50% was moved one digital level lower to match with Digital Video Essentials HD Basics. This makes the grayscale steps equal, in terms of the digital luma values, except for the first step above black. Previously the uncommon step had been near the middle of the grayscale, instead of above black. This item is primarily related to rounding from the digital luma values to the percentages shown on-screen, but more details from the previous known issue can be found in this comparison or these measurements.
- The ColorHCFR section titled Near Black now only provides patterns to match with the default setting for “Number of near black levels”. Previously the series was set according to the default output from ColorHCFR, but currently the luma values above black have been moved one level lower to correspond with the change to 5% Grayscale listed above. The steps between the Near Black patterns are now equal, and the previous uneven step between 0% and 1% has been removed.
- The ColorHCFR section titled Near White was also reduced to match with the default setting for “Number of near white levels”. No levels were altered in the Near White series, so they still match with the output from ColorHCFR. This alteration in the number of patterns offered was simply made to correspond with the change to Near Black.
- Removed previous pattern titled RGB Low Clipping from project, because the original intent can generally be handled by other patterns.
- Renamed previous RGB High Clipping pattern to Color Clipping. This pattern was modified to include more levels below Red, Green, and Blue for displays that are clipping colors.
- Changed Misc. Patterns Section A to primarily serve as Additional patterns for black-level and white-level. Flashing Primary Colors and Flashing Color Decoder have been moved to Section B.
- Misc. Patterns Section B still serves as Various patterns from the project that do not fit into other categories. The crosshatch patterns have been moved to a new Misc Patterns Section C.
- Misc. Patterns Section C now contains patterns primarily focused on Convergence, but the crosshatch patterns could also be used for geometry adjustments. The requested convergence patterns have been added by permission. These patterns were created using images on the HDMV and AVCHD versions, while the MP4 uses video for the first two patterns.
- Misc. Patterns E now includes 75% Color Windows and 75% Color Fields, and the video has not been flagged. These 75% Color patterns can be measured and compared with the flagged 75% Color video from the CalMAN, ChromaPure, or ColorHCFR Windows or Fields sections. In the comparison you would check to see if color remains the same for both the unflagged video from Misc. Patterns E and the flagged video found in the other sections. Ideally the color should not change regardless if the video for the 75% Color has been flagged.
- Misc. Patterns F includes flagged and unflagged video for a visual check to see if color remains the same for both videos. The HDMV and AVCHD versions automatically switch between the two clips, while the MP4 version would require switching between clips using the video player. Ideally the color should not change regardless which clip is played.
- Misc. Patterns K is a newly added video from dr1394 that uses progressive video, where the alternating frames are labeled 1 and 2. This is Mpeg2 video that is not included in the AVCHD or MP4 versions, like the other Misc. Patterns G to L that are also from dr1394.
- Due to other Misc. Patterns changes, some Misc. Patterns sections now use a different letter than on the previous version but are otherwise unchanged.
- Because of menu changes and to limit disc size, ColorHCFR and CalMAN sections no longer include duplicate patterns for setting black-level and white-level. The adjustment patterns can be found in Basic Settings and Misc. Patterns A, and a popup menu link is provided between the sections. The ColorHCFR grayscale patterns from Adjust Gray have been placed in a new 25% Grayscale section.
- CalMAN sections have been rearranged and renamed to match CalMAN v4 pattern layouts. CalMAN measurement patterns no longer use 30 second chapters, and they are now the same length as all other sections. We are aware the new 5 Step series is not backward compatible with the 6 step option from CalMAN v3, and for simplicity we have chosen to make the pattern layout consistent for CalMAN v4. The 2 Step option was not added because it does not start with white like the other sections, and the 3 Step video could be used instead for some measurements. We have chosen to leave color choices at 75% and 100%. Only 11 and 21 step patterns include above white measurements in CalMAN software, but all window and field series include above white to be consistent with other sections. Each section begins with white and you will be taken to that location by selecting chapter 1 from the menus, or you can choose to go to the chapter 2 from the CalMAN menus. The chapter 1 and 2 options allow for the different measurement selections in CalMAN software.
- Sections were added to support ChromaPure v2. Gamma sections include an unused pattern for 0% at the end. Grayscale series for windows and fields include above white at the end to be consistent with the other measurement sections.
- APL measurement patterns have been moved, off of the windows menus, onto separate menus. The large and small series have also been split into separate sections. The APL series will not offer all the options available for fields or windows. APL 25% series have been added for ColorHCFR, and APL 3 Step series have been added for CalMAN. The APL series are not described as windows in any documentation, simply to avoid confusion with typical window patterns.
- The Contrast sections for window and field measurements had the order of patterns 3 and 4 reversed, for black then white to match with the first two patterns. Previously the ANSI Contrast patterns used levels 1 and 254 to match the output from ColorHCFR, but they have been changed to use levels 16 (black) and 235 (white) to match with the grayscale range commonly found on commercial Blu-ray video. A new Meter Position pattern has been added to the end of the contrast sections to locate measurements in the center of each rectangle for patterns 5 and 6.
- New Meter Position patterns were added for Windows, Fields, and APL patterns.
- Dynamic & Center pattern was renamed Dynamic Brightness, although it still retains the center mark."-

gracias por el aviso, esperemos que se hayan vuelto a meter los menús para navegar entre los IRE y dentro de los colores y esas cosas lo cual era muy útil para los reproductores. Como son los patrones del chromapure?
