2.1 The Genesis is a film camera that records digitally
Genesis was designed to work comfortably within the established practices of film crews. Genesis cameras take most of the standard Panavision 35mm accessories. Camera assistants familiar with film will find the same follow-focus, matte-box, filters and heads that they already use for 35mm. The SRW-1 VTR is mounted like a Panavisi on m a gazine either abov e or on th e back of the camera.
Cinematographers and directors can call for the same lenses, and get the same look and depth of field as standard 35 mm. Man y directors of photography light for Genesis the same way they would light for an E.I. 500 Tungsten film stock.
Three key differences from the film experience are that HD monitors are incomparably sharper than 35mm video assist, that “reloading” 50 minute cassettes ( or a Solid State Recorder) almost instantaneous, and that there is no delay before dailies are ready.
2.2 Menus and maintenance
Genesis is easy to use. The camera comes loaded with carefully chosen default settings that will work for most applications. During prep, the Camera Assistant will access a few menus to define the project frame rate, monitor frame lines and time code format.
On the set, Genesis is ready to record as soon as it is turned on and black balanced. The camera’s LCD screen allows for quick access to basic functions like shutter angle, film speed, film type or variable speed. When switching cassettes, the Camera Assistant will use a VTR menu to change time code.
V39
Panavision Genesis Manual v1.318
Beyond normal cleaning there is very little field maintenance to be done on Genesis. Panavision provides information and training necessary to do simple field procedures
2.3 Recording
At present , most Genesis productions shoot on videotape using the on-board Sony SRW1 HDCAM SR recorder. Panavision sees 3 advantages to videotape:
1. Videotape recorders have a proven track record in the extremes of temperature, humidity and mechanical shock that are commonplace in today’s productions.
2. The 50 minute duration all ows for length y takes and rapid reloads.
3. Feature films require hundreds of terabytes of data, and videotape offers a very practical way to protect all your footage for the future.
Sony developed the SRW1 field recorder to directly interface to the Genesis and in that mode the VTR is seamlessly controlled and configured by the camera.
You also have the option to record the Genesis 4:4:4 Dual Link HD­SDI outputs to a Solid State Recorder, a separate hard drive, or other storage solutions. The Genesis signal can be recorded by any system that accepts dual link HDSDI.
2.4 HDCAM SR 50 minute load s
At 24 frames per second in standard SQ mode, the SRW-1 VTR records 50 minutes per HDCAM SR cassette. Just as with a film camera, you get m ore or les s re c ordi ng time at lower or hi gh e r speeds. At the top speed of 50 fps, the cassette recording time is halved.
V39
Panavision Genesis Manual v1.319
2.5 FPS and progressive
The frame rate you choose will depend on the release requirements of your project. Genesis and SRW-1 offer the following fixed progressive frame rates: 23.98P – 24P – 25P – 29.97P and 50P.
Most American Genesis features have been shot at 23.98 fps. This allows for on-set playback of down-converted NTSC video with sync sound. Most US Genesis TV is shot at 23.98 fps, while European and Australian TV are shot at 25 fps.
It is also possible to shoot interlaced frame rates of 50I, 59.94I and 60I. The disadvantage of interlace is that the image is captured in two different moments of time, creating motion artifacts. Most productions do not shoot interlace unless intercutting with television cameras is required.
2.6 Separating the Genesis and VTR
If desired, the Genesis camera body an d VTR can be separat e d, for example for a lighter Steadicam configuration, or inside a car. The Genesis can also be outfitted with a Solid State Recorder when a minimum weight and volume are required.
When the VTR is recording the signal from a separate camera, Panavision recommends that you to shoot in the full color resolution of 4:4:4. This entails using the “Dual Link” connection using 2 BNC cables (as opposed to single cable 4:2:2).
2.7 The 4:4:4 and 4:2:2 fo rmats
Panavision recommends that you record 4:4:4 if possible, even for a 4:2:2 finish. Simply put, the difference between 4:4:4 and 4:2:2 is that 4:4:4 allocates the same amount of information to the color and to the black and white portions of the image, while 4:2:2
V39
Panavision Genesis Manual v1.320
allocates less information to color than black and white. Historically, the num be rs 4 and 2 ref e r to the multiples of a reference f re q uency. The important thing to remember is the ratio of information.
2.8 Variable speed
Genesis cameras can shoot and record at any fixed speed from 1 to 50 f ps. However , the cam era does not ramp between speed s. The SRW-1 VTR does not record 4:4:4 at speeds over 29.97 fps. In order to accommodate the immense amount of data generated at speeds of 30 fps and above, the camera must be switched to 4:2:2.
Panavision recommends that you consult chapter 23 before recording variable speed. Note that, at present, the SRW-1 cannot record variable speed correctly when separated from the Genesis camera body.
2.9 Shutter a ngles
The Genesis shutter can be set at any angle between 3.8 and 360 degrees. Shutter angles above 200 degrees are new territory for the film cinematograph e r, y iel di n g a different exposu re , an d a differe n t rendering of motion. At 360 degrees (or “Shutter Off”) the exposure time is twice as long as it is at 180 degrees. Therefore, the 360 degree shutte r capt u re s more m otion blur, an d m ore ligh t, than 180 degrees.
You can use the shutter for artistic effect or to gain an additional stop of exposure or bot h. Some cinematographers experim e nt with a range of shutter angles between 180 and 360 to creatively modulate the resulti n g exposure gain and motion blur.
The effects of HMI lights are identical on Genesis and film, and require similar shutter settings. The advantage of Genesis is that
V39
Panavision Genesis Manual v1.321
you can see any pulsing directly on t he monitor. Panavision recommends testing if you plan to shoot with HMIs at unusual shutter angles.
2.10 Inter cutting Genesis with film
Genesis and film intercut beautifully. This is partly due to Genesis’ capturing a wider color space than standard vide o. Pan av i sion recommends that you shoot tests with the emulsion you are planning to use and work with your post house to develop your strategy for handling the two materials.
2.11 Exposure Index
As with film, the EI setting is a technical and aesthetic choice made by the director of photography. Most DPs will set the Genesis between 500 and 640. However all cinematographers have noted that the Genesis is considerably more sensitive in the blacks than film.
In addition the sensitivity of the camera increases with bigger shutter angles: a 360 degrees shutter will yield twice as much exposure as 180 (with twice the motion blur).
2.12 Color reference
The Genesis does not use white balance, so it is not necessary to shoot a wh ite c a rd for proper ope ra tion, as wi th video cameras. Instead the director of photograph y chooses wheth e r the Genesis is set for “Tungsten”, “Daylight” or a given color temperature. Some cinematographers will also shoot a grey card or a chip chart as a color refere nce for post- production.
V39
Panavision Genesis Manual v1.322
2.13 Panalog and GDP
The Genesis camera signal is transformed by a Panalog transfer curve designed by Panavisi on to maximize the latitude of the im age for subsequent fil m or vi de o finish. Simply put, the Panalog allocates more steps in the darks where the human eye is more discriminating, and fewer in the whites. Panalog also preserves Genesis’ wide color gamut, a color space that is close to that of film.
Because of its wide latitude , the Pan alog vi de o output will not be properly displayed on a video m oni t or. The im a ge may look w a shed out and underexposed. Some cinematographers simpl y adjust the brightness and contrast of their monitors to get a rough feel for the final image. However the Panavision GDP (Genesis Display Processor) offers a m uch better solution by applying a precise Viewing LU T (C ol or l ook-up table) to th e si gn a l for viewing on video monitors on the set or in dailies. This LUT correction can also be applied to the images going to the edit room.
2.14 Pre-vi sua li zing
One of the ben ef i ts of shooting Gene s is is that the footage doe s n ot require scanning for DI (digital intermediate) like film does. Panavision strongly recommends that the cinematographer work closely with the post-production house at the outset of production to define the post workflow. Some DPs use Viewing LUTs defined by post houses and loaded into the Panavision GDP to pre-visualize the look of the re lea se print on the set, and in HD proje c t ion of dailies.
