Strip#
Header#
- Type
Strip type, represented by an icon.
- Name
A text field to adjust the name of the strip, which is shown on the strip in the timeline.
- Color Tag
The color of the strip in the timeline. By default, strips are given a Default Color based on the type of strip. The color tag can change the color to an alternative predefined color.
This can be useful to help organize your sequence by for example, giving a special color to all graphic overlays and a different color for footage.
- Mute
Toggles the strip from producing an output.
Compositing#
Reference
- Panel:
- Blend
The method for blending the current strip with strips in lower channels. See Blend Modes for more information.
- Opacity
The transparency (alpha) of the strip.
When this property is animated, the opacity is drawn as an overlay on the strip. The overlay will look like a dark section that follows the animation curve. This can be hidden by disabling the F-Curves.
Transform#
Reference
- Panel:
- Filter
The technique used to estimate the values of pixels at non-integer coordinates within the image.
- Auto:
Automatically choose filter based on scaling factor.
No scale, no rotation, integer positions: Nearest
Scaling up by more than 2x: Cubic Mitchell
Scaling down by more than 2x: Box
Otherwise: Bilinear
- Nearest:
No interpolation; uses nearest neighboring pixel (fastest).
- Bilinear:
Interpolate between 2×2 samples.
- Cubic Mitchell:
Cubic Mitchell filter on 4×4 samples.
- Cubic B-Spline:
Cubic B-Spline filter (blurry but no ringing) on 4×4 samples.
- Box:
Averages source image samples that fall under destination pixel.
- Position X, Y
Used to move the frames along the X and Y axis.
- Scale X, Y
Scale the image on the X and Y axis.
- Rotation
Rotates the input two-dimensionally along the Z axis.
- Mirror
Mirrors the image along the X axis (left to right) or the Y axis (top to bottom).
Crop#
Reference
- Panel:
Used to crop the source image. Use Top, Left, Bottom, and Right to control the number of pixels that are cropped.
Video#
Reference
- Panel:
- Strobe
Display every nth frame. For example, if you set this to 10, the strip will only display frames 1, 11, 21, 31, 41… of the source.
It is important to realize that this property is a float value. This allows you to strobe effect synced exactly to a beat.
- Reverse Frames
Plays the strip backwards starting from the last frame in the sequence.
Color#
Reference
- Panel:
- Saturation
Adjusts the vividness of colors in the image.
- Multiply
Multiplies the colors by this value. This will increase the brightness.
- Multiply Alpha
Multiply alpha along with color channels when using the Multiply option.
- Convert to Float
Converts input to float data.
Sound#
Reference
- Panel:
Working with sound is documented further at Sound Strip.
- Volume
Adjusts the perceived loudness or intensity of the sound
When this property is animated, the volume is drawn as an overlay on the strip. The overlay will look like a dark section that follows the animation curve. This can be hidden by disabling the F-Curves. The value is also reflected in the waveform.
- Pan
Used to pan the audio between speakers in multichannel audio. Only mono sources can be panned, if the source file is not mono enable Mono to mix the channels together.
This value basically represents the angle at which it’s played if you multiply the value by 90 degrees.
For stereo output panning works from left (-1) to right (1); where 0 means front/center, -1 means to the left and 1 to the right.
To address rear speakers, you can pan to those with the higher values; where -2 is back left, and 2 is back right.
Tip
For smooth animation you can assign values outside the soft bounds, since the angle wraps around over multiple rotations.
Note
The number of audio channels can be configured in the Audio Output settings.
- Display Waveform
Display an approximate waveform of the sound file inside of the Sound strip. The waveform reflects strip volume and its animation using keyframes.
Clipping audio, i.e. values over 100% amplitude, will be shown in red in the waveform.
- Mono
Mixdown all audio channels into a single channel.
Time#
Reference
- Panel:
The Time panel is used to control source and timeline position of the strip.
- Lock (padlock icon)
Prevents the strip from being moved (found in the panel header).
- Show Retiming Keys
Toggle visibility and selectability of Retiming keys.
- Channel
Changes the channel number, or row, of the strip.
- Start
Changes the starting frame number of the strip, which is the same as selecting and moving the strip.
- Duration
Changes the length, in frames of the strip. This works by changing the end frame, which is the same as selecting and moving the strip’s right handle.
- End
Specifies the ending time and ending frame number for the strip.
- Strip Offset Start/End
Can be used to either extend the strip beyond the end frame by repeating the last frame. Or it can be used to shorten the strip, as if you were cropping the end frame. This is the same as adjusting the strip handles.
- Hold Offset Start/End
Offset of the uncut strip content.
- Current Frame
The frame number relative to the start of the active strip.
Source#
Reference
- Panel:
The Source panel is used to control sources of the strip such as filename and file path and various methods of interpreting these files.
- Path
The directory that contains the source file. When the file is moved, the path can be updated instead of recreating the strip.
- File
The file name of the source file. For image strips showing an image sequence, this will be different for each frame.
- Change Data/Files
Same as the Path and File fields, but this time combined to open the File Browser in order to find the file(s) you search. Same as .
- Color Space
To specify the color space of the source file.
The list of color spaces depends on the active OCIO config. The default supported color spaces are described in detail here: Default OpenColorIO Configuration
- Alpha Mode
If the source file has an Alpha (transparency) channel, you can choose:
- Stream Index Movie Strip
For files with several movie streams, use the stream with the given index.
- Deinterlace
Removes fields in a video file. For example, if it is an analog video and it has even or odd interlacing fields.
- Source Information
Displays information about the strip’s media.
- Resolution
Resolution of the active strip image output.
- FPS Movie Strip
The frame rate encoded into the video file. If this value does not match the scene Frame Rate the perceived speed of the media will be wrong unless the speed is changed to account for the difference in frame rate.
Options for Sound Strips#
