Summary
[edit]

The LTC Out CHOP outputs "linear timecode" which is a SMPTE timecode data encoded into an audio signal. See also Linear Timecode.

Use an Info CHOP to determine which values are currently being output.

The output of this CHOP can be sent to an Audio Device Out CHOP.

Parameters - LTC Page

Play play - Specifies whether the count should increment or hold steady.

Frame frame - The initial frame to count from.

Second second - The initial second to count from.

Minute minute - The initial minute to count from.

Hour hour - The initial hour to count from.

Frame Rate framerate - The number of complete frame messages per second the signal encodes. It is usually between 24 and 30.  

Audio Rate audiorate - This audio sampling rate of the output signal.  

Drop Frame Numbering dropframe -

Reset reset - While set to on, the output is held at the specified initial values above.

Reset Pulse resetpulse - When pulsed, the output is held at the specified initial values above.

Parameters - Common Page

Time Slice timeslice - Turning this on forces the channels to be "Time Sliced". A Time Slice is the time between the last cook frame and the current cook frame.

Scope scope - To determine which channels get affected, some CHOPs use a Scope string on the Common page.

Sample Rate Match srselect - - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or "Linear" if the Interpolate Options are not available.

  • Resample At First Input's Rate first - Use rate of first input to resample others.
  • Resample At Maximum Rate max - Resample to the highest sample rate.
  • Resample At Minimum Rate min - Resample to the lowest sample rate.
  • Error If Rates Differ err - Doesn't accept conflicting sample rates.

Export Method exportmethod - - This will determine how to connect the CHOP channel to the parameter. Refer to the Export article for more information.

  • DAT Table by Index datindex - Uses the docked DAT table and references the channel via the index of the channel in the CHOP.
  • DAT Table by Name datname - Uses the docked DAT table and references the channel via the name of the channel in the CHOP.
  • Channel Name is Path:Parameter autoname - The channel is the full destination of where to export to, such has geo1/transform1:tx.

Export Root autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.

Export Table exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).

An which operate on (a series of numbers) which are used for animation, audio, mathematics, simulation, logic, UI construction, and many other applications.

The term "Frame" is used (1) in the , (2) as a time-unit in CHOPs, (3) as a time-unit in TOPs, and (4) with movies images which are read and created with TOPs.

The frame rate that TouchDesigner's uses. Equal to the Frames per Second value project.cookRate.

To pulse a parameter is to send it a signal from a CHOP or python or a mouse click that causes a new action to occur immediately. A pulse from a CHOP is typically a 0 to 1 to 0 signal in a channel, and a pulse via python is via a .pulse() call on a pulse-type parameter, such as Reset in a .

A Time Slice is the time from the last cook frame to the current cook frame. In CHOPs it is the set of short channels that only contain the CHOP channels' samples between the last and the current cook frame.

A parameter in most CHOPs that restricts which channels of that CHOP will be affected. Normally all channels of a CHOP are affected by the operator.

samples-per-second of a CHOP. Each CHOP in your network has a sample rate, whether it is used or not. The overall timeline has a "frame rate", which is the number of animation frames per second, generally your monitor display frequency.

Exporting is the connection of CHOP channels to parameters of operators. The output of each exporting CHOP is one or more channels, active only while the is on. The current value of a channel can be exported to a parameter of any operator, overriding that parameter's value. See .

An that manipulates text strings: multi-line text or tables. Multi-line text is often a command , but can be any multi-line text. are rows and columns of cells, each containing a text string.

The location of an operator within the TouchDesigner environment, for example, /geo1/torus1, a node called torus1 in a component called geo1. The path / is called . To refer instead to a filesystem folder, directory, disk file or http: address, see .

Parameters in TouchDesigner are an operator's settings (numbers, menus, flags, strings, paths) which the user can alter. Parameters for any operator can be opened by right-clicking on the operator and selecting "Parameters..." A currently selected operator's parameters can be viewed in a by pressing the keyboard shortcut 'p'.

TouchDesigner is a hierarchy of components. "root" is the top-most network in the hierarchy. The is simply /. A typical path is /project1/moviein1.
