VTRIn

Function
This node is only available in Tremor, but can be read into Shake. It acts as a special FileIn that can either be used to capture footage from the digibeta decks, or can reference captured footage in yuv format from the disk array.

The process to use this footage is generally:

Parameters
Type
Defaults
Function
autoAlpha
int
0 This will create a solid alpha channel for the image when it is illuminated.
deInterlacting
int
0 This will deinterlace the image, doubling up its fields. When the value equals 1, the odd fields are used. This is generally the setting for PAL. When it equals 2, the even fields are used, which is generally the setting for NTSC.
timeCodeMode
string
"Film 24 FPS"

"24 FPS" -

"25 FPS"

"NTSC DF" - there is a dropped frame to compensate for the 29.97 fps frame rate

"NTSC ND" - there are no dropped frames to compensate for the 29.97 fps frame rate.

inTimecode
string
"00:00:00:00" The point at which capturing will start. This can manually be entered, or entered by using the Viewer controls to shuttle to your in point and hitting I with the cursor over the Viewer.
outTimecode
string
"00:00:00:00" The end point of the capture. This can be set manually or by hitting O in the Viewer. You can also automatically calculate this by entering a duration and the inTimecode
duration
string
"00:00:00:00" The length of the clip.
lockDuration
int
1  
reelName
string
  The name of the reel, and also the subdirectory in which the data is saved. Typically, one names this based on a project or scene. If you don't supply a name, you will be prompted to supply one or accept a default name.
clipName
string
 

The name of the directory under reelName and the name of the yuv file, thus you end up with something like:

/TremorMedia/reelName/clipName/clipName.00001.yuv, etc.

yuvDecode
int
1 When this is on, the yuv channels are converted to rgb channels. It may be useful to leave this off when capturing converted 4:1:1 footage, as you can easily apply a blur to the chroma channels to clean it up. See Overview - About Keying - Pulling a Key on DV.
