Light Source - Blackmagicdesign Cintel Installation And Operation Manual

Scan Speed: With adequate disk performance, you should be able to scan at 30 fps.
‚
However, if you're scanning to a slow hard drive, you can reduce the scanning speed to
a frame rate that's suitable for your workstation without dropping frames.
Supply: Sets the wind direction of the left-hand side feed spool. While auto-detection
‚
will prevent incorrect operation, you should manually configure the reel winding
direction based on how each film roll is wound.
Take up: Sets the wind direction of the right-hand side take up spool. While
‚
autodetection will prevent incorrect operation, you should manually configure the reel
winding direction based on how each film roll is wound.
Use Film Reel: Small film reels have a different weight and inertia compared to large
‚
film spools, and this can affect the transport system. Tick this box to switch to settings
that offer improved stability for small film reels.
Focus Assist: Enables luminance peaking on your scanner's HDMI monitor output, plus
‚
the viewer inside DaVinci Resolve's film scanner panel, which makes it easy to obtain
optimum focus adjustments.

Light Source

These controls let you adjust the scanner's light source to adjust the optimal Dmin, which is the
minimum scanned signal value, plus the color temperature of the scanned material. Use the
built in software scopes in DaVinci Resolve to help set your light source to its optimum level
settings. Scopes can be opened in the Media page by choosing Workspace > Video Scopes >
On. You can adjust these settings to make sure you're not clipping image data during the
scanning process.

Light Source master wheel:
‚
to the color wheel and adjusts the intensity of the light source used to illuminate the
film, raising or lowering the RGB channels all at once. For typical negative film, this lets
you adjust the black point of the film image, which is the darkest part of the image. In
negative film, this in fact corresponds to the highlights of the film image. Adjust the light
intensity to sit just above the typical Dmin value of 95, as measured on the histogram
of the video scopes, which guarantees that the highlights won't be clipped by a
Cineon-style LOG conversion. For positive film, simply adjust the master wheel so that
no part of the signal is being clipped.
Auto Black and Auto White button:
‚
and does an automatic adjustment to set the black point for negative, or for print to set
the white point. For positive film types, the 'auto black' button changes to 'auto white'.
