The Shift CHOP time-shifts a CHOP, changing the start and end of the CHOP's interval. However, the contents of the channels remain the same.
Each channel can be shifted a different amount by using the $C variable in the Scroll parameter or the Start/End parameters.
An optional second input, the Start/End Reference, is used to align the first input CHOP relative to another reference CHOP. This outputs the channels of the first CHOP only, and the shifts are based on the interval of the second CHOP. It is useful for making several CHOPs match up to the same time.
Parameters - Shift Page
reference - ⊞ - The start or the end of the channels can be used as the reference position. The channels are shifted by altering the reference position.
- Start Position
refstart- Uses the start of the CHOP to do the aligning.
- End Position
refend- Uses the end of the CHOP to do the aligning.
relative - ⊞ - Determines how the Start and End parameters are to be interpreted:
abs- The Start/End parameters are the actual start/end position. It is used, for example, to shift the CHOP to start at 0 seconds.
- Relative to Start/End
rel- The Start/End parameters are a shift relative to the input CHOP's start/end position.
- Relative to Current Frame
cur- Ignore the Start/End parameters and use the current frame as the new start position.
start - The start of the interval, absolute or relative to the input CHOP.
end - The end of the interval, absolute or relative to the input CHOP.
scroll - Without changing the length of the CHOP, you can scroll the channels within its range, and scroll each channel a different amount. By using $C in the parameter, you can make the scroll amount dependent on the channel index.
Scroll Offset Unit
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).
