Some digital cinema projection best common practices – Knut Erik Evensen – KESEThe best cinemas comply with the current DCI Specifications and SMPTE 4. DCI/SMPTE 4. 31 compliant. The first versions of the DCI specifications described all aspects of digital cinema projection like the minimum contrast ratio and the white illumination target. The latest version says that cinemas must follow the projector environment described in these two SMPTE 4.

ST 4. 31- 1: 2. 00. D- Cinema Quality – Screen Luminance Level, Chromaticity and Uniformity. RP 4. 31- 2: 2. 01. D- Cinema Quality, Reference Projector and Environment. RP 4. 31- 2: 2. 01. ST 4. 31- 2: 2. 00.

PCF) called virtual white. Different kind of cinemas: –SMPTE 4. Review room 1. 4 f. L, 1. 00: 1 Intra frame contrast, 1. Sequential contrast–SMPTE 4. Cinema Theatre 1. L, 1. 00: 1 Intra frame contrast, 1.

Sequential contrast- Studio Projection Guidelines calibrated. L.–Uncalibrated uncalibrated. L. The best cinemas are the common height cinemas where scope films are projected wider than flat films.

The best cinemas recalibrate their lamps at least once per week to get a flicker free image and the recommended light level of 1. L for 2. D and 7 (5- 9) f.

L for 3. D. If the image still flickers or is too dim after a cold start and auto adjustment, the lamp should be changed. The best cinemas keep their port glass, 3. D systems and optics clean to avoid a washed out picture.

This must be done according to instructions in the projector manual. Link: Christie CP- 2. The best cinemas keep up with cinema technology improvements like Atmos and better silver screens like Harkness CLARUS XC and REALD ULTIMATE SCREENThe best cinemas have good acoustics with a mix of reflective and damping materials on the walls.

The best cinemas are adjusted and calibrated to sound good. The best cinemas are powerful enough to be able to play content at reference levels.

The best cinemas do not turn down the volume faders to low levels for all features because some are mixed too loud. See this post for more info. Example: In a Uncalibrated cinema with 3.

L and low contrast ratio: -The image will be too bright.- Black will be gray.- Dark scenes will look brighter.- Muddy and washed out picture. In the Studio Projection guidelines “The Pixar Projection guidelines” you find some tests that will insure better projection. These are similar to other studio projection guidelines that film studios deliver with their films: http: //projection. D/http: //projection.

D/The tests mentioned in the studio guidelines are projection best common practices in digital cinemas: -adjust the white illumination to 1. L (using a DCI White test image, not a projector white test image which is 1. L)- check and adjust the framing with a framing chart,- check the sound for 8. Bc per channel and play the movie at reference level (7 on dolby, 0 on other equipment)This is how I do the standard tests from the projection guidelines: 1. Check for 1. 4 f. L“Lamp Levels. Projection lamp levels that are set too low have a disastrous effect on the picture. When projected at the SMPTE standard of 1.

L full white, the image is sharp and colorful. At lower levels, the colors become muddy and gray. The picture has less snap to it and feels lifeless. Important details in the darker areas will disappear if the light levels are too low. The acceptable range is between 4. L to 7 f. L. Real.

D ZScreen System and other polarized systems: Remove filters from the projector. Set the light level between 3. L. With the Sekonic L- 7. Cine I check that the the white is betweeen 3. L illuminated from the middle of the screen which will become 4.

L to 7 f. L when glasses are used and the Masterimage/Real. D 3. D system is on.

Another test that should be included is a basic intra frame contrast test. To read the intra frame contrast accurately you need the Minolta LS- 1. Intra Frame test image DCP.

But with a Sekonic L- 7. Cine or L- 7. 58- C- U spotmeter and a projector checkerboard test image you could measure the light from the black and white squares and get some idea of what the intra frame contrast is. The intra frame contrast should be 1. Theaters according to SMPTE/DCI. If you get around 0,5 f. L in the black squares, the intra frame contrast is around 3. Kremlin 2 21 Serial Cracked here. If the intra frame contrast is bad you could try to: – Clean the port glass and optics.– Avoid spill light from projection booth.– Use matte black seats and furnishing.– Install a iris in the projector.– Upgrade to a RGB laser projector.

Check the framing chart. If the movie has a framing chart you can adjust a preset on the projector to fit the framing chart.

It is important to avoid cropping 3. D movies because it could break the 3. D illusion on movies with floating windows. You can also use the projector framing test images to check framing. You could also check if the picture is in focus when checking the framing. Check sound levels. Your theater sound system should be tuned to 8.

B (C- weighted) on all screen channels using pink noise. The correct fader setting on Dolby and DTS systems is 7. On SDDS systems, the correct master volume setting is 0. Use a SPL meter to check the d.

BC level. If there is a drop in d. BC in one channel you should check speakers and amplifiers for faults. You should also play a familiar DCP at the reference level to check if the sound system works OK.

Note: A cinema sound system can pass the 8. C test without having enough amplifier power headroom. The pink noise signal that is measured to 8. C is - 2. 0 Dbfs, a cinema system should also be able to play louder material without clipping. Note: Many films these days (2. The dialogue can be mixed at high levels and you need to turn the fader down to a low level.

These movies lack dynamics. Notes: RTA/SPLAlternatively you could use a Real Time Analyzer (RTA) to check d. BC level when playing the pink noise.– With a RTA/SPL you would see both the pink noise frequencies and the pink noise d. BC level.– If there is some frequencies missing on the display when playing the pink noise an amplifier, speaker or other equipment could be faulty.– With a RTA/SPL You will notice which frequencies are peaking. I’ve tried the Behringer DEQ2.

ECM8. 00. 0 microphone as a SPL/RTA and the umik- 1 microphone with 9. REW as a SPL/RTA. They will both give decent measurements . The DCI/SMPTE standards. Some cinemas may need to change port glass, change audio equipment, change screen, upgrade to series 2 projectors, dual projectors, laser projectors and similar actions to meet the DCI/SMPTE standards.

The X- Curve/8. 5 dbc sound standard: Virtually all cinema playback systems today are aligned using SMPTE 2. M or ISO 2. 96. 9. The two documents are virtually the same and both define the measuring method and the resulting frequency response known as the “X- Curve”. This provides a uniform frequency response adjustment for all theaters throughout the world.

Cinema playback is also tuned to a specific level. All standard cinema systems are optimized for 8. B SPL (2/3rds back in the center) from each front channel and 8.

B SPL for each of the rear channel arrays. All channels should have 2.

B of headroom. The LFE channel is set at 1. B of in band gain; that is, 1. B greater than the screen channels in each 1/3 octave frequency band. SPL ranges from 8. B to 9. 2d. B, depending upon the specific bandwidth of the LFE system in use.–“Recommendations for Surround Sound Production” - The Recording Academy’s Producers & Engineers Wing.
