With Snap Frames, all
key and range bar positions that are changed are forced to absolute
frame increments. This includes selection sets of multiple 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 Time
Display format MM:SS:Ticks, which doesn't use frames, Snap Frames
snaps to time values that match frame boundaries.
In Dope Sheet Edit Keys mode, keys
are displayed as a box grid. Keys that are snapped to frames are
displayed as filled 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
WarningDon'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 they won't be noticeably
different in Curve Editor. In some cases, sub-frame keys can lead
to animation “popping,” or overly fast changes due to keys being
too close together.
To use Snap Frames:
Snap Frames is on by
default, so the following procedure only applies if you have turned
off snap frames previously.
- On the Track View Dope Sheet toolbar,
NoteThis isn't an absolute
necessity, but it makes it easier to see the snapping action. You
can also view the snapping in the track bar in either Dope Sheet
or Curve Editor mode.
- On the Track View toolbar, turn on (Snap Frames).
- In the Track View Key window, select
one or more keys.
- Use (Move
Keys) or Scale Keys
to move the keys.
With Snap Frames on,
each key in a selection set snaps to the nearest frame when the
selection is moved or scaled.
