Dischi pattern utili per calibrare

[Tacco]

Okay, non avevo capito che si trattava sempre del discorso legato a quel software e quella procedura...
Ettore

[biasi]

in linea generale se su calman decidi di impostare manualmente il livello del nero devi stare poi attento a cosa fa la procedura di autocal quando misura il nero;quello che volevo segnalare è che in questo caso è meglio non impostare il livelo del nero a mano ma di farlo misurare alla procedura

[Tacco]

Io, dall'alto della mia sincera ignoranza, non so nemmeno quale sia il motivo per cui uno debba inserire a mano il livello del nero.
Nel senso... io l'ho sempre fatto rilevare alla sonda in calibrazione, quindi non so proprio quale sia il motivo per cui o il caso nel quale si debba inserire tale valore a mano...
Ettore

[biasi]

un motivo è quello dell'automatismo dei pattern di Ted che con sonde come la i1 display pro non si porebbe fare altrimenti (il nero a essere rilevato ci impiega troppi secondi)
un'altro motivo è la possibile ritenzione durante la visualizzazione dei pattern soprattutto se si parte dal visualizzare il pattern 100% che va a rendere il valore del nero (usato per la black compensation) magari più alto di quello che dovrebbe essere

In relazione al disco di pattern "Ted's LightSpace CMS Calibration Disk" ho ricevuto questa informazione dall'autore:

"Hello, I have just uploaded a new webpage with a lot of detailed instructions about the available Measurement Solutions for Ted's LightSpace CMS Calibration Disk users.

These instructions are helpful the for Free Version or Full Version of the disk users.

There a lot of picture examples and text instructions that makes pretty difficult to post all these instructions here, so you have to visit that page:

Measurement Solutions for CalMAN/ChromaPure users using Ted's LightSpace CMS Calibration Disk

The Measurement Solutions page is covering the following topics:

1) Importance of calibrating from the actual movie playback source.

2) Semi-Automated Measurements for CalMAN users with details and instructions.

3) Semi-Automated Measurements for ChromaPure users with details and instructions.

4) Automated Measurements Procedure for CalMAN users details, instructions, very detailed example about how the Batch Utility files are working with CalMAN and other notes. "

Sempre in relazione al disco di pattern "Ted's LightSpace CMS Calibration Disk" l'autore del disco mi ha oggi informato di quanto segue:

"DVDO's AVLab TPG 4K Reference Pattern Generator has added a new and very useful feature that is called 'Color Checker'. Using that feature it can display digital value for selected pixel from it's HDMI Input.

Pressing the left/right TPG buttons changes decimal to hex. It will read RGB/YC, 8/10/12 bit values.
"Cursor" is moveable around the screen using DVDO's remote.

A professional calibrator from using Ted's LightSpace CMS Calibration Disk has tested yesterday the accuracy of the encoded chapters of the disk using that AVLab TPG's color checker function.

He measured 100% Saturation and 100% Luminance RGBCMY Patterns, Color Checker patterns and Near-Black Patterns of the CalMAN section of the disk.

He found that the Ted's LightSpace CMS Calibration Disk has been encoded properly and every single bit is on it's reference position.

This means that Ted's LightSpace CMS Calibration Disk can be used from DVDO's AVLab TPG 4K Reference Pattern Generator users as a reference and now they can able to check any Blu-Ray Player / Media Player Output accuracy and detect digital errors that wrong player settings can introduce.

Mede8er MED800x3D and eGreat R6S Media Players used as a source for that test. Both made no digital errors on HDMI output.

Here is the link of the full review and procedure details that the professional calibrator from Poland has used for this test."

Visto che lui non lo fa (mostrando ancora una volta riluttanza all’autoreferenzialità), vi posto Biasitar, pattern “dinamico” creato dal nostro Riccardo per la lettura alternativa del Nero che in questo caso vaga nel bel mezzo di scene a voi tutti note.

P.S. Riccardo, scusami se mi sono permesso

sperando di fare cosa gradita vi riporto la email che l'autore del disco "Ted's LightSpace CMS Calibration Disk" mi ha inviato per informarmi della nuova versione di HCFR:

"Dear disk users,

There some interesting new measurement options for HCFR users that using Ted’s LightSpace CMS Calibration Disk.

HCFR 3.1.7 (free open source calibration software) has been released and it's adding some extra measurement options for Ted's LightSpace CMS Calibration Disk of Free Version or Full Version users. For full HCFR release notes look here.

Using HCFR 3.1.7 (or later version) with Ted’s LightSpace CMS Calibration Disk Chapters that are available to the CalMAN/ChromaPure sessions of the disk, you can take measurements for the following Color Checker Patterns:

For Ted’s LightSpace CMS Calibration Disk (Free Version) users:

CalMAN’s Color Checker Classic (24 Colors)

For Ted’s LightSpace CMS Calibration Disk (Full Version) users:

CalMAN’s Color Checker Classic (24 Colors)
CalMAN’s Color Checker SG (96 Colors)
CalMAN’s Color Checker SG Fleshtones (19 Colors)

Mi sono accorto solo oggi che il disco di Ted contiene una piccola (ma per me molto importante) caratteristica che consente di trovare con grande precisione il livello giusto del Brightness della propria catena video.
In passato spesso abbiamo avuto diversi punti di vista su quale fosse il migliore pattern in proposito: personalmente ritenevo finora l'Advanced Brightness del disco Wow Disney quello più utile e preciso.
Da oggi affianco al suddetto il pattern Advanced Brightness Flashing Bars (presente nel capitolo "Pre-Calibration Tools") del disco di Ted.
Questo pattern infatti, oltre a visualizzare le classiche barre per Bianco, Primari e Secondari, presenta un dettaglio (di cui mi sono accorto solo oggi) secondo me utilissimo. (Probabilmente molti di voi lo avevano già notato).
Se fate caso, lateralmente a sinistra è presente una scritta verticale "This is Reference Black & should be not visible" che non dovrebbe essere appunto visibile quando il Brightness è correttamente visualizzato.
In pratica consiglio di fare così: aumentate dapprima il Brightness per rendere la scritta visibile. Poi, click dopo click, riducete il Brightness fino a quando arrivate al livello in cui non è più visibile: quello è il giusto Brightness.
Semplicissimo e rapidissimo!

Below you can find the updated list of the total CalMAN and ChromaPure Chapters that any HCFR user can use to take measurements. These Disk Chapters are accurate and match the HCFR's Color Engine Calculations:



Instructions for x-Point Grayscale ChromaPure's Chapters Measurements

Uncheck ''use round down levels" that is located to HCFR ''Preferences'' -> ''General'' Tab. This is affecting only Grayscale measurements.

Instructions for Color Checker Chapters Measurements



Before starting the measurements you have to select from HCFR's Preferences -> ''References'' Tab -> ''Color Checker Patterns'' drop down menu list the selection of the measurement run you want to perform.

Select ''GCD'' if you want to measure using ChromaPure's Color Checker Chapter.

Select ''ChromaPure skin tones'' if you want to measure using ChromaPure's Color Checker Skin Tones Chapter.

Select ''CalMAN Classic'' if you want to measure using CalMAN's Color Checker Classic Chapter.

Select ''CalMAN SG'' if you want to measure using CalMAN's Color Checker SG Chapter.

Select ''CalMAN SG skin tones'' if you want to measure using CalMAN's Color Checker SG Flesh Tones Chapter.

Instructions for CalMAN's x-Point Saturation/Luminance Chapters Measurements

To enable these measurements the users have to download the usercolors_pak.zip of HCFR.

By extracting the files of the HCFR's usercolor_pak, below are the Ted's LightSpace CMS Calibration Disk Pattern Sequences of the CalMAN's Session you can use with HCFR 3.2.0:



CM 4-Point Saturation (100AMP).cvs file for CalMAN's 4-Point Saturation (100% Stimulus Level) Chapter.

CM 4-Point Saturation (75AMP).cvs file for CalMAN's 4-Point Saturation (75% Stimulus Level) Chapter.

CM 5-Point Saturation (100AMP).cvs file for CalMAN's 5-Point Saturation (100% Stimulus Level) Chapter.

CM 5-Point Saturation (75AMP).cvs file for CalMAN's 5-Point Saturation (75% Stimulus Level) Chapter.

CM 10-Point Saturation (100AMP).cvs file for CalMAN's 10-Point Saturation (100% Stimulus Level) Chapter.

CM 10-Point Saturation (75AMP).cvs file for CalMAN's 10-Point Saturation (75% Stimulus Level) Chapter.

CM 6-Point Near Black.cvs file for CalMAN's 6-Point Near Black Chapter.

CM Dynamic Range (Clipping).cvs file for CalMAN's Dynamic Range (Clipping) Chapter.

CM 4-Point Luminance.cvs file for CalMAN's 4-Point Luminance Chapter.

CM 5-Point Luminance.cvs file for CalMAN's 5-Point Luminance Chapter.

CM 10-Point Luminance.cvs file for CalMAN's 10-Point Luminance Chapter.

Note: The pattern sequence of CalMAN's 10-Point Luminance is identical to the Color Checker Selection ''RGB Luminance Axis'', so it can be selected from the drop-down menu available @ HCFR's Preferences -> ''References'' Tab.

These new measurement selections currently are now available to the HCFR's Color Checker Pattern drop down menu. To enable any of the measurement option the user has to rename the CMxxxxxxx.cvs measurement file want to perform to usercolors.csv and place it to the same folder where the HCFR has installed (where the HCFR's executable is located), and select from the HCFR's Color Checker Pattern list the ''User defined'' option.



This can be performed while the HCFR is running, for example to do one measurement run; and then replace the CVS file to load the new colors set... and hit the delete icon next to the grid.

For being more user friendly, If there much interest from the HCFR users that using Ted's LightSpace CMS Calibration disk; then these measurement options will be probably selectable from the Color Checker's drop down list in a future release of HCFR. You can request this from Zoyd, the current developer of HCFR to this thread.

Note that there differences between the RGB Targets of CalMAN vs. ChromaPure ColorChecker & Skintones or Saturation patterns.

Thanks Zoyd (current developer of HCFR) for adding these new measurement options for Ted's LightSpace CMS users of HCFR."
