35mm and 16mm
In TV3 there were three new Steenbeck Editing machines 2 for 16mm and One 35mm. It so happen that an elderly old man give a basic training on editing on how splice the film. I just Love this Steenbeck machine,
Picture:
The picture is projected via an optical compensation system using an 18 facet revolving prism. Accurate film transport is assured by a revolving sprocket ring which guarantees a smooth film transport maintaining excellent picture steadiness whilst, most importantly, taking care of the film stock. The picture quality and steadiness are maintained at all speeds in both forward and reverse directions. The picture exposure system utilises a special condenser lens and filter system providing an exceptionally bright and crisp image whilst ensuring that damaging heat is removed from the exposure light thus protecting the film. The exposure light is automatically dimmed when the transport is stopped to allow for constant viewing of the "still" frame without fear of heat damage to the stationary film. The 100W Quartz Halogen exposure lamp can be changed and adjusted from the top of the drive deck.
The projection system is fitted with highly polished front surface coated mirrors and dirt and is easily cleaned.
Sound:
The amplifiers are of a modular design and construction. Every machine can be fitted with a maximum of 7 pre-amplifiers for magnetic and optical sound as required. A summing amplifier provides control of the overall volume, treble and bass levels to suit any individual requirement. Another two important features, fitted as standard, are a Dynamic Compressor and Automatic Muting at high speeds, both of which enhance user comfort.

MPEG2
5 x SD TV (4.5MB/s ) = 22.5
or
1 HDTV (14MB/s) + 2 x SDTV (4.5MB/s) = 23
MPEG4
7 x SDTV (3 MB/s) = 21
or
1 HDTV (9 MB/s) + 4 x SDTV (3 MB/s) = 21
AUDIO
Several different audio level standards.
There are +4dbU, -10dbV, digital
The metering in the audio mixer control is related to VU metering in that a level of 0 corresponds to the nominal signal level of the particular audio source
For instance, a -10dbV sinewave tone (.316 volts RMS) applied to an RCA input shows a level of 0 in the VT audio mixer, just as a VU meter should by definition.
A +4dbu tone (1.23 volts RMS) applied differentially to the XLR input reads 0, as a VU meter on this type of pro equipment should.
Notice that the meters in the VT audio mixer are not labeled with dbu, dbV, dbfs, etc. A level of 0 means the nominal signal level.
Using this method puts the levels on "equal footing" in the VT audio mixer. When a tone is output, the -10dbV, +4dbu, and -15dbfs levels should appear at the RCA, XLR, and digital audio outputs when the VT mixer output meter is showing a level of 0 on the output meters on the right side of the VT mixer.
If you were to play a test clip that shows a level of -20 on the VT mixer output meter, you should get about -35dbfs on a digital scope, because 0 corresponds to about -15dbfs. Subtract 20 from -15dbfs and you arrive at -35d
Notice that the meters in the VT audio mixer are not labeled with dbu, dbV, dbfs, etc. A level of 0 means the nominal signal level.
