Biên Soạn -- Editing¶

Transform¶

Tham Chiếu -- Reference

Mode: Edit Mode
Trình Đơn -- Menu: Key ‣ Transform

An F-curve can be edited by transforming the locations of the keyframes.

Move, Rotate, Scale: Like other elements in Blender, keyframes can be moved, rotated, or scaled as described in Basic Transformations.
Extend: Moves keyframes relative to the Playhead. If the mouse is to the left of the Playhead, this operator only affects the selected keyframes that are to the left of the Playhead. On the contrary, if the mouse is to the right of the Playhead, this operator only affects the selected keyframes that are to the right of the Playhead.

Mẹo

For precise control of the keyframe position and value, you can set values in the Active Keyframe of the Sidebar region.

Bám Dính -- Snap¶

Phím Tắt -- Hotkey: Ctrl-RMB, Shift-Ctrl-RMB

Inserts a keyframe to the active F-curve at the mouse position. The newly added keyframes will be selected, making it easier to quickly tweak the newly added keyframes. All previously selected keyframes are kept selected by using Shift-Ctrl-RMB.

Add F-Curve Modifier¶

Tham Chiếu -- Reference

Trình Đơn -- Menu: Key ‣ Add F-Curve Modifier
Phím Tắt -- Hotkey: Shift-Ctrl-M

Opens a pop-up allowing you to add modifiers to the active F-curve. Settings for the modifier can be found in the Sidebar ‣ Modifiers tab.

Nướng Âm Thanh thành Đường Cong-F -- Bake Sound to F-Curves¶

Tham Chiếu -- Reference

Trình Đơn -- Menu: Khóa (Key) ‣ Nướng Âm Thanh thành Đường Cong-F (Bake Sound to F-Curves)

The Bake Sound to F-Curves operator takes a sound file and uses its sound wave to create the animation data.

Lowest Frequency

Cutoff frequency of a high-pass filter that is applied to the audio data.

Highest Frequency

Cutoff frequency of a low-pass filter that is applied to the audio data.

Attack Time

Value for the hull curve calculation that tells how fast the hull curve can rise. The lower the value the steeper it can rise.

Release Time

Value for the hull curve calculation that tells how fast the hull curve can fall. The lower the value the steeper it can fall.

Giới Hạn -- Threshold

Minimum amplitude value needed to influence the hull curve.

Chồng Chất/Tích Tụ -- Accumulate

Only the positive differences of the hull curve amplitudes are summarized to produce the output.

Bổ Sung -- Additive

The amplitudes of the hull curve are summarized. If Accumulate is enabled, both positive and negative differences are accumulated.

Hình Vuông -- Square

Cho kết quả là một đường cong hình vuông. Các giá trị âm luôn luôn có kết quả là -1 và những giá trị dương là 1

Giới Hạn Hình Vuông -- Square Threshold: Tất cả các giá trị thấp hơn ngưỡng này sẽ cho kết quả là 0.

Jump to Keyframes¶

Tham Chiếu -- Reference

Trình Đơn -- Menu: Key ‣ Jump to keyframes
Phím Tắt -- Hotkey: Ctrl-G

Places the 2D cursor at the center of the selected keyframes.

Copy/Paste¶

Tham Chiếu -- Reference

Trình Đơn -- Menu: Key ‣ Copy Keyframes, Key ‣ Paste Keyframes
Phím Tắt -- Hotkey: Ctrl-C, Ctrl-V

Use Ctrl-C to copy selected keyframes and Ctrl-V to paste the previously copied keyframes. During the paste action, the Adjust Last Operation panel provides some options in how the paste is applied.

Offset

No Offset: Pastes the keyframes in the location they were copied from.
Frame Relative: Pastes the keyframe relative to the Playhead position based on the locations of the keyframes relative to the Playhead when they were copied.
Frame Start: Pastes the keyframes with the first keyframe of the copied set placed at the Playhead.
Frame End: Pastes the keyframes with the last keyframe of the copied set placed at the Playhead.

Type

Mix: Integrates the pasted keyframes in with existing keyframes only overwriting keyframes that share a frame.
Overwrite All: Removes all previous keyframes and replaces them with the pasted keyframes.
Overwrite Range: TODO
Overwrite Entire Range: TODO

Duplicate¶

Tham Chiếu -- Reference

Trình Đơn -- Menu: Key ‣ Duplicate
Phím Tắt -- Hotkey: Shift-D

Duplicates the selected keyframes. You can reposition them by moving the mouse.

Delete Keyframes¶

Tham Chiếu -- Reference

Trình Đơn -- Menu: Key ‣ Delete Keyframes
Phím Tắt -- Hotkey: X, Delete

Pressing X or Delete opens a pop-up menu from where you can delete the selected keyframes.

Handle Type¶

Tham Chiếu -- Reference

Trình Đơn -- Menu: Key ‣ Handle Type
Phím Tắt -- Hotkey: V

Sets the handle type of the selected keyframes.

Interpolation Mode¶

Tham Chiếu -- Reference

Trình Đơn -- Menu: Key ‣ Interpolation Mode
Phím Tắt -- Hotkey: T

Sets the interpolation mode between the selected keyframes.

Easing Mode¶

Tham Chiếu -- Reference

Trình Đơn -- Menu: Key ‣ Easing Mode
Phím Tắt -- Hotkey: Ctrl-E

Sets the easing mode of the selected keyframes.

Decimate¶

Tham Chiếu -- Reference

Trình Đơn -- Menu: Key ‣ Decimate (Ratio)
Trình Đơn -- Menu: Key ‣ Decimate (Allowed Change)

The Decimate tool simplifies an F-curve by removing keyframes that influence the curve shape the least.

Mode

Controls which method is used pick the number of keyframes to use.

Ratio: Deletes a defined percentage of keyframes, the amount of keyframes to delete is define by the Remove property.
Error Margin: Deletes keyframes which only allowing the F-curve to change by a defined amount. The amount of change is controlled by the Max Error Margin which controls how much the new decimated curve is allowed to deviate from the original.

Làm Sạch Khung Khóa -- Clean Keyframes¶

Tham Chiếu -- Reference

Trình Đơn -- Menu: Khóa (Key) ‣ Làm Sạch Khung Khóa (Clean Keyframes)
Phím Tắt -- Hotkey: X

Clean Keyframes resets the keyframe tangents on selected keyframes to their auto-clamped shape, if they have been modified.

Dọn Dẹp các Kênh -- Clean Channels¶

Tham Chiếu -- Reference

Trình Đơn -- Menu: Key ‣ Clean Channels
Phím Tắt -- Hotkey: X

Acts like the Clean Keyframes tool but will also delete the channel itself if it is only left with a single keyframe containing the default property value and it's not being used by any generative F-curve modifiers or drivers.

Ghi chú

The modified curve left after the Clean tool is run is not the same as the original, so this tool is better used before doing custom editing of F-curves and after initial keyframe insertion, to get rid of any unwanted keyframes inserted while doing mass keyframe insertion (by selecting all bones and pressing I for instance).

Smooth Keys¶

Tham Chiếu -- Reference

Trình Đơn -- Menu: Khóa (Key) ‣ Làm Mịn Khung Khóa (Smooth Keys)
Phím Tắt -- Hotkey: Alt-O

There is also an option to smooth the selected curves, but beware: its algorithm seems to be to divide by two the distance between each keyframe and the average linear value of the curve, without any setting, which gives quite a strong smoothing! Note that the first and last keys seem to be never modified by this tool.
