Setting Video Input and Output Engineering Menu Controls
Clip input and output engineering options include video I/O settings such as pre-roll, post-roll, play delay,
colour space conversion, and settings that define the process by which YUV video material on a tape is
converted to the RGB format used by Smoke, and vice-versa.
To change the default Engineering menu settings for a VTR device on a Mac system, edit the VTR configuration
files using the provided Smoke Setup utility.
When you start Smoke and set the video I/O timing for your project, enabled VTR devices are initialized,
and the settings in the Engineering menu are populated accordingly. However, if necessary, you can modify
these settings on a session-to-session basis.
To open the Engineering menu:
1 From the VTR Input module, click Eng, or from the VTR Output module, click the Engineering tab, to
open the Engineering menu.
Engineering Menu Options
Consult the following illustration (broken into three parts) and explanations of the options in the Engineering
menu. These illustrations are of the VTR Input Engineering menu. The VTR Clip Engineering menu contains
a subset of these controls.
(a) Device Name box (b) Video I/O Timing box (c) Precision box (d) Timecode Source box (e) Input and Output
Connection boxes (f) Colour Space box (g) Output Sync box (h) VTR Current Timecode field (i) PreRoll/PostRoll fields
(j) Cue Up box (k) Error Retry field (l) Proxy Box
Device name box The Device Name box differentiates between 3G and non-3G capable VTR and provides
an option for each enabled VTR. To modify settings for a specific VTR device, select the corresponding option
from this box.
Video I/O Timing box Provides video timing options (resolution and frame rate) corresponding to different
video formats supported by the video input/output board of the system.
Precision box Determines the video interface precision, or SDI bit depth used. This value cannot be changed.
