Important PrecautionsTo ensure continual high performance from the camcorder take thefollowing precautions into consideration:Avoid very damp places. If the environment is wetor damp a rain cover must be used to protect theunit.Do not subject the unit to severe shocks or vibration.Do not expose the camera to extremes oftemperature.Do not leave the unit in direct sunlight or close toheating appliances for extended periods.Do not allow sunlight to shine into the viewfinder.ivViper

WarningIf the camera is in a wet or damp environment, a rain cover must beused to protect it for personal safety reasons (EN60065). The optionalrain cover protects the camera according to safety specificationEN60529 up to level IPX2 (spraying water).FCC Class A StatementThis equipment generates, uses, and can radiate radio frequencyenergy and if not installed and used in accordance with the instructions,may cause interference to radio communications.It has been tested and found to comply with the limits for a class Adigital device pursuant to part 15 of FCC rules, which are designed toprovide reasonable protection against such interference when operated in a commercial environment.Operation of this equipment in a residential area is likely to causeinterference in which case the user at his own expense will be requiredto take whatever measures may be required to correct the interference.03.18.5v

Section 1IntroductionThis section describes the FilmStream mode of operation andoutlines the technology used in the Viper. The access andsecurity features of the camera are also explained.ContentsSelecting operational mode . 1-2Streaming modes . 1-3Technology . 1-4Access and Security . 1-6IntroductionFilmStream mode1-1

Selecting operational modeTo operate in the FilmStream mode you must ensure that the camerais switched to this mode. The output signals and the control functionsthat are available depend on the mode you select.The factory default for the mode setting is the FilmStream mode, sonormally you do not have to switch modes to operate the camera asa digital film camera.If a different mode has been set up, then you need to switch to theFilmStream mode by changing a menu setting (for more details referto Section 5).To1.2.3.4.change modes:Open the menu system.Go to the Install menu.Select Output mode item.Change the value to FilmStream or HDStream.The camera remembers the last selected mode, so it remains in theFilmStream mode even when switched off and on again.MonitoringTo provide a monitoring signal for viewing, a separate channel is usedwhich undergoes some video processing to make it acceptable forviewing on monitors and viewfinders. Although derived from the samesensor signals, this channel is entirely separate from the main FilmStreamoutput.The Viper does not have any adjustable visual parameters for theFilmStream outputs. Framing, focussing, exposure setting, shutterangle and optical filtering are the only operations required of thecamera and lens operators.1-2FilmStream modeViper

Streaming modesFilmStream modeThe FilmStream mode differs from the HD video mode in that itcaptures all information in a scene and stores it digitally withoutaltering any parameters. By avoiding video processing in the raw RGBdata, the output signal is a true and faithful representation of the lightfrom the scene. Thus the FilmStream digital data signals are full-rangesignals suitable for film post-production without any loss of information.Capturing the lightThe Viper uses three high-definition CCD sensors to register the lightfrom the lens. The signals from these sensors are converted to R, G, andB data values using 12-bit A/D converters. Using logarithmic calculationsthis data is then converted to 10-bit values and transferred to a recorderusing a dual HD-SDI link. Full resolution is maintained: true-progressive1920 x 1080 pixels for every color. No color sub-sampling, no colorspace conversions, no irreversible video manipulations, no furtherquantizations, and no compression is carried out.HDStream modeThe output mode can also be set to HDStream. This mode providessignals similar to the FilmStream signals but in a 4:2:2 HD-SDI format.These HDStream signals are subject to white balancing in the camerabut like FilmStream signals, they do not undergo any other videoprocessing. HDStream mode is ideal when storage capacity is limitedor for applications where lower resolution signals are sufficient, suchas background for keying.IntroductionFilmStream mode1-3

TechnologyCCD sensor technologyThe Viper FilmStream Camera uses three unique 9.2 Megapixel HDDPM CCD sensors that allow the camera to work in several formats;1080 lines at 24/25/30 frames per second or 720 lines at 24/25/30/50/60 frames per second.This CCD sensor is based on the Frame-Transfer principle which is bestsuited for progressive images. The Viper uses a mechanical shutterwhich means that the CCD exposure has a similar ramp to film cameras,thus providing similar motion characteristics.FormatsThe 0i720p720p720p720p720pformats can be selected in the Install menu:at 23.98Hzat 24Hzat 25Hzat 29.97Hzat 50Hzat 59.94Hzat 59.94Hz - 23atatatatat23.98Hz25Hz29.97Hz50Hz59.94HzThe sensor consists of 1920 horizontal pixels and 4320 vertical subpixels. By grouping the vertical sub-pixels, the vertical line count canbe set. Full resolution is preserved and the horizontal viewing anglestays the same. 1080PWhen four vertical sub-pixels are combined, the total line countbecomes 1080 lines. So, a 1920 x 1080 image sensor is obtained witha 16:9 aspect ratio.1-4FilmStream modeViper

1080iWhen eight vertical sub-pixels are combined, the total line countbecomes 540 lines. The second field is shifted four pixels to give aninterlaced picture. 720PWhen six vertical sub-pixels are combined, then the total line countbecomes 720 lines. So, a 1920 x 720 image sensor is obtained with a 16:9aspect ratio. When set to 60 frames per second, slow motion effects canbe achieved during post-production at different playback speeds. Cinemascope Aspect RatioWhen three vertical sub-pixels are combined, 1440 vertical lines areobtained. By using the middle 1080 lines, a 2.37:1 aspect ratio isachieved without the need for anamorphic lenses while maintainingfull 1920 x 1080 resolution. There is no need to crop the image or loseresolution to get this aspect ratio.IntroductionFilmStream mode1-5

Access and SecurityCamera cardsThree camera cards are delivered with each camera; one owner’s cardand two user cards. An owner’s card is linked to the serial number ofthe camera and is unique to that camera. It cannot be used as anowner’s card for another camera.The owner’s card acts as: an access control device to the security settings of the camera. a storage card for four scene files and two operator files.The user card stores four scene files and two operator files.Operator files contain information relating to the set-up of generalcamera preferences. Scene files contain information relating to thevideo settings of the camera head.Owner’s card1-6User cardFilmStream modeViper

Access controlThe owner’s card or the PIN code is used to access special set-up andsecurity features of the camera. Inserting the owner’s card into thecamera gives direct access to the Security menu. If you select theSecurity menu without this card inserted, you must enter the correctPIN code to gain access to this menu.User levelsFour user levels can be set in the security menu. These restrict access,in varying degrees, to the operational controls. The appendix indicateswhich functions are available at each user level.ClearStar 4PStar 6PSoft focA 1ClearB 2ND1/4C 3ND 1/14ND 1/6us D6411Camera card slotInsert your camera card into this slot with the chip on the card facingthe front of the camera.
