Trim CHOP

Summary

The Trim CHOP shortens or lengthens the input's channels. A part of the interval can be preserved or removed. If the channels are being lengthened, the extend conditions of the channel will be used to get the new values.

The Trim CHOP is sometimes used to get a 1-sample value at the current frame, where the inputs are channels at frame 0 or channels at some other frame range.

The handles on the Trim CHOP in the graph can interactively adjust its length.

Parameters - Trim Page

Unit Values relative - - Determines whether the Start/End parameters are expressed as absolute numbers (relative to time 0) or numbers that are relative to the start and end of the input channels.

  • Absolute abs - The Start and End are the actual numbers defining the new interval.
  • Relative to Start/End rel - The Start and End are relative to the start and end of the input CHOP.
  • Relative to Current Frame cur - Only one sample is output, containing the channel values at the current frame.
  • Current Time Slice slice - Channel value is based on the current time slice.

Start start - The start of the range to trim. The numbers are expressed in seconds, frames or samples, depending on units menu for each parameter.  

Start Unit startunit -  

End end - The end of the range to trim. The numbers are expressed in seconds, frames or samples, depending on units menu for each parameter.  

End Unit endunit -   NOTE: If the Start Value is greater than the End Value, the Trim CHOP will behave as if both values are the Start Value.

Discard discard - - Which part of the channel to discard:

  • Exterior exterior - Discard those parts of the channel outside the trim range.
  • Interior interior - Discard the interior of the trim range. If two intervals remain, sequence them together.

The CHOP is shortened by increasing the Start relative value, and lengthened by decreasing it. The CHOP is lengthened by increasing the End relative value, and shortened by decreasing it.

See the Extend CHOP for more details on t


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).
