Snap Frames
Maintoolbar>CurveEditor(Open)>Keysmenu>Snap
Frames
Graph Editor > Track View - D ope Sheet/Track Vi ew -
Curve Editor > Keys menu > Snap Frames
With Snap Frames, all key and range bar positions
that are changed are forced to absolute frame
increments.Thisincludesselectionsetsofmultiple
keys. When Snap Frames is on, each key in a
selection set will snap to the nearest frame when
the selection is moved or scaled. Default=on.
When you use the T ime Display format
MM:SS:Ticks, which doesn’t use frames, Snap
Frames snaps to time va lues that match frame
boundaries.
In Dope Sheet > Edit Keys mode, keys are
displayed as a box g rid. Keys that are snapped to
frames are displayed as fil led boxes. Keys that have
been moved with snap frames off are displayed as
narrow rectangles within the grid. When using
the Curve Editor, a similar display is available in
the track bar.
Subframe keys moved with snap frame off
Wa rn in g: Don’t turn off Snap Frames unless you have a
reason to, such as the need for more precise animation
timing. If you do turn off Snap Frames and move keys in
Curve Editor you will create sub-frame keys, but t hey
won’t be noticeably different in Cur ve Editor. In some
cases, sub-frame keys can lead to animation “popping,”
or overly fast changes due to keys being too close
together.
