A Avainkehys on ajanmerkki, joka tallentaa ominaisuuden arvon.

Esimerkiksi, Avainkehys voi määrittää, että kuution horisontaalinen sijainti, kehyksessä 1, on 3m.

The purpose of a Keyframe is to allow for interpolated animation, meaning, for example, that the user could then add another key on frame 10, specifying the cube’s horizontal position at 20m, and Blender will automatically determine the correct position of the cube for all the frames between frame 1 and 10 depending on the chosen interpolation method (e.g. Linear, Bézier, Quadratic, etc.).

Visualisointi

3D-näkymissä on joitain tärkeitä visualisointitoimintoja, jotka voivat auttaa animaatiota.

When the current frame is a keyframe for the current active object, the name of this object (shown in the upper left corner of the 3D Views) turns yellow.

Avainkehykseen tyypit

For visually distinguishing regular keyframes from different animation events or states (extremes, breakdowns, or other in-betweens) there is the possibility of applying different colors on them for visualization.

Left: not selected; Right: selected.

Keyframe (white / yellow diamond)
Tavallinen avainkehys.
Breakdown (small cyan diamond)
Erittelytilanne, e.g. tilanne, esim. asentojen siirtymisten avainkehyksien välillä.
Moving Hold (dark gray / orange diamond)
A keyframe that adds a small amount of motion around a holding pose. In the Dope Sheet it will also display a bar between them.
Extreme (big pink diamond)
’Äärimmäinen’ tilanne, tai jokin toinen tarkoituksen, tarpeen mukaan.
Jitter (tiny green diamond)
Täyttökehys tai ”baked” – merkittyjä, generoituja ja muistuttuja esilaskutoimituksia – avainkehysten tai muita avainkehyksiä varten, tai jotakin muita tarkoituksia, tarpeen mukaan.

Handles & Interpolation Display

Dope Sheet can display the Bézier handle type associated with the keyframe, and mark segments with non-Bézier interpolation. This facilitates basic editing of interpolation without the use of the Graph Editor.

Top: summary; Middle: Bézier; Bottom: linear.

The icon shape represents the type of the Bézier Handles belonging to the keyframe.

Circle Auto Clamped (default)
Circle With Dot Automatic
Square Vector
Clipped Diamond Aligned
Diamond Free

If the handles of a keyframe have different types, or in case of summary rows representing multiple curves, out of the available choices the icon that is furthest down the list is used. This means that if a grouped row uses a circle icon, it is guaranteed that none of the grouped channels have a non-auto key.

Horizontal green lines mark the use of non-Bézier Interpolation. The line is dimmed in summary rows if not all grouped channels have the same interpolation.

Display of this information can be disabled via the Show Handles and Interpolation option of the Dope Sheet’s View Menu.
