Converting Between Raw and Standard Fcurves

You can convert from raw to standard spline fcurves, and vice versa, in the fcurve editor.

Converting from raw to standard fcurves is useful for saving memory and increasing performance when using fcurves from motion capture animation or plotted animation.

Standard fcurves created have fewer points and have spline interpolation.
Raw fcurves created from plotted actions are not supported.

When you convert a standard spline fcurve to raw, the raw format includes only the minimal information needed (no slopes and the interpolation is linear).

To convert from raw to standard fcurves

Select one or more raw fcurves.
Choose the Curves Convert to Standard command.
You are prompted with a warning that "This command is not undoable. Do you want to proceed?" This process is not undoable to save memory.

Click Yes to convert the curve to a Standard format.

To convert from standard to raw fcurves

Select one or more standard (spline) fcurves.
Choose the Curves Convert to Raw command.
You are prompted with a warning that "This command is not undoable. Do you want to proceed?" This process is not undoable to save memory.
