The Timeline CHOP outputs time-based CHOP channels for a specific component. The time channels are defined by a Time Component whose Path can be determined using the python expression
me.time. When a Reference Node is specified, the time defined at that node is used. When the Reference Node is not specified, then the time defined at the Timeline CHOP's location is used (ie. time defined at
Parameters - Timeline Page
op - This node is used to specify the time referenced by the Timeline CHOP. The time is defined by the Time COMP found at
frame - Output a channel for frame number.
rate - Output a channel for the rate (frames per second).
start - Output a channel with the Start frame value.
end - Output a channel with the End frame value.
rangestart - Output a channel with the Range Start frame value.
rangeend - Output a channel with the Range End frame value.
signature1 - Output a channel for the first number in the timing signature, how many beats are in a measure.
signature2 - Output a channel for the second number in the timing signature, which kind of note constitutes one beat.
bpm - Output a channel with the BPM value.
play - Output a channel with the current play state.
Parameters - Common Page
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 - 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.
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
autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.
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 generic thing that holds an , and includes (display, bypass, lock, render, immune) and its position/size in the network. Whether you "lay down an Operator" or "lay down an Node", you're doing the same thing.
Any of the procedural data operators. OPs do all the work in TouchDesigner. They "cook" and output data to other OPs, which ultimately result in new images, data and audio being generated. See .
An that contains its own inside. There are twelve 3D and eight 2D types. See also .
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.
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
