Timeline CHOP

Summary

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 me.time).

Parameters - Timeline Page

Reference Operator op - This node is used to specify the time referenced by the Timeline CHOP. The time is defined by the Time COMP found at me.time  

Frame frame - Output a channel for frame number.  

Rate rate - Output a channel for the rate (frames per second).  

Start start - Output a channel with the Start frame value.  

End end - Output a channel with the End frame value.  

Range Start rangestart - Output a channel with the Range Start frame value.  

Range End rangeend - Output a channel with the Range End frame value.  

Signature 1 signature1 - Output a channel for the first number in the timing signature, how many beats are in a measure.  

Signature 2 signature2 - Output a channel for the second number in the timing signature, which kind of note constitutes one beat.  

BPM bpm - Output a channel with the BPM value.  

Play play - Output a channel with the current play state.  


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).
