Capture Menu Options

About Capture and Playout			Controlling the VTR
Chapter 20, Video Capture and Video Playout

Use the Capture menu to perform your VTR capture operations.

Note: Capture can only be done using the DVS or AJA video cards. The GFX/SDI options listed below are provided as reference only and should not be used during the capture.

The following three graphics represent the Capture menu.

Video/Graphics option box	Format option box	Audio Input button
Raster list	Full Range button	VTR Status panel
Pulldown button	Link Type option box

Video/Graphics option box--Toggle between the video card (AJA or DVS) and the graphics card (GFX/SDI). The Raster list is then populated with rasters for the selected card.

Warning: When capturing, do not select a raster for the GFX/SDI card. Doing so is not supported and can result in failed capture.

Raster list--With a video card selected in the Video option box (AVIO), select one of the listed rasters to set the resolution and timing for capture. For more information about rasters, see Supported Video SDI and GFX SDI Rasters.

Format option box--Toggle to display only rasters belonging to a particular footage format in the Raster list.

Select:	To display:
SD	Standard definition rasters.
HD	High definition rasters.
Film	Film rasters.
Audio	Audio rasters (only applicable to GFX/SDI).

Note: Enable an Audio Only raster when monitoring the GFX/SDI output and working with audio signal coming out of the AJA/DVS break out box. This is similar to working with audio media or to using the LTC chase feature with a DVS.

Link Type option box--Toggle to display only rasters belonging to a particular link type in the Raster list.

Select:	To display:
Single	The single link rasters.
Dual	The dual link rasters.
Stereo	The stereoscopy rasters (only applicable to GFX/SDI).

Full Range button--Enable to configure Lustre to capture the full video signal from the video board. If disabled, Lustre captures only the legal portion of the video signal.

Pulldown button--Enable to remove 3:2 pulldown from Film-to-video transferred material. See Removing Pulldown when Capturing.

Sync Mode list-- Select one of the sync modes.

Select:	To:
InternalSync	Set the sync mode to a free running internal sync (SD and HD).
ExternalSync	Genlock to an analog sync connected to the sync input (SD only).
TrilevelSync	Genlock to a trilevel sync connected to the sync input (HD only).

Video Capture Format list--Select a video capture format to set file type, colour space, and bit depth of the captured material.

Select:	To capture only:
Dpx 10Bit RGB	DPX files with an RGB colour space at a bit depth of 10-bit.
Tiff 8Bit RGB	TIFF files with an RGB colour space at a bit depth of 8-bit.
AVI 8Bit RGB	AVI files with an RGB colour space at a bit depth of 8-bit (available only on Windows workstations.)

Audio Capture Format list--The supported capture format is a Wave file (.WAV) with a sampling frequency of 48,000 hertz and a bit depth of 24-bit.

Log panel-- Displays status messages during capture.

TC button--Initiates a capture from VTR using timecode in and out points. See Capturing from Timecode.

EDL button--Initiates a capture from VTR using an EDL. See Auto-conforming an EDL.

Note: EDL Capture is video only; audio events are ignored.

Timecode In Point field--Enter the start timecode. Press Set next to the field to set the current timecode (read from the VTR) as the in point.

Timecode Out Point field--Enter the end timecode. Press Set next to the field to set the current timecode (read from the VTR) as the out point.

EDL Log Add button--Logs the In and Out timecode points as an EDL for capture. See Logging and Batch Digitizing.

Note: Only video events are supported for EDL logging.

Handle button--Enable to capture heads and tails. This feature is used when capturing from an EDL.

Note: You must enable the Handle button to use the Handle slider.

Handle slider--Set the number of head and tail frames to capture.

V button--Enable to capture the video track when capturing from a video source. Disable to capture audio only.

A1 - A8 buttons--Enable the audio tracks (A1-A8) to capture from an audio source.

VTR Status panel--Displays the VTR status messages when Lustre is connected to a VTR.

Audio Input option box--Toggle to specify the source of the captured audio.

Select:	To specify the connection to the audio source:
Embedded Audio	The SDI connection.
AES	The XLR connections on the DVS/AJA break-out box.

Video Delay field--Enter a frame number to delay the video capture for that number of fields. For example, if you set the field to 10, the capture begins 10 frames after the In point. If you set the field to -10, capture begins 10 frames before the In point.

Audio Delay field--Enter a frame number to delay the audio capture for that number of fields. For example, if you set the field to 10, the audio capture begins 10 frames after the In point.

Note: The Video and Audio Delay fields compensate for frame delays that may exist while transferring shots from the capture to Lustre.

Pulldown Field buttons--Enable a Pulldown Field button to select the frame used for the 3:2 pulldown. Only available when Pulldown is enabled. See About 3:2 Pulldown.

Standby Off button--Removes the VTR heads from the tape.

Eject button--Ejects the tape in the VTR.

Home field--Displays the project home directory. This is the destination path for captured footage. You cannot change this value without modifying your project settings.

Scene field--Displays the current scene you are working in during capture. You cannot change this value without modifying your project settings.

Capture field--Enter the name of the folder where video media is saved.

Tape field--Displays the tape name. When capturing in TC mode, enter a tape name. When capturing from an EDL, the default tape name is determined by that EDL. If you capture an EDL with multiple tapes, a folder structure (<tape>/<resolution>/) is created for each tape (e.g., 0001/1920x1080).

Resolution field--Defaults to the resolution of the captured files, and is used in the folder structure. Do not change this field.

File field--Displays the filename, which is the frame offset value based on the source timecode (e.g., 84600.dpx is 1:00:00:00 at 24 fps). <NUM7> defines the amount of padding for the file name (for example, 084600.dpx reflects six digits of padding before the extension). You can add a prefix before the <NUM7> number, but to ensure consistent frame counting, do not erase the <NUM7> number (e.g., Mymovietitle.084600.dpx).
