Strip

Adjust Panel

Reference

Panel:Sidebar region ‣ Strip ‣ Adjust

The Adjust panel is used to control visual properties of strips.

Compositing

Blend
Mode of blending strip with lower channels.
Opacity
Set the opacity (alpha) of the strip.

Transform

Image Offset
Used to move the frames along the X and Y axis. Additionally it disables the auto-scaling of the image.
Image Crop
Used to crop the source image, use Top, Left, Bottom, and Right to control which part of the image is cropped.

Video

Strobe
To only display each nth frame. For example, if you set this to 10, the strip will only display frames 1, 11, 21, 31, 41… of the source. Strobe is a float value – this way you can get a strobe effect synced exactly to a beat, for example, by using non-integer values.
Reverse
Plays the strip in reverse (time).
Deinterlace
Removes fields in a video file. For example, if it is an analog video and it has even or odd interlacing fields.
X Flip
Mirrors the image along the X axis (left to right).
Y Flip
Mirrors the image along the Y axis (top to bottom).

Color

Saturation
Increase or decrease the saturation of an image.
Multiply
Multiplies the colors by this value. This will increases the brightness.
Convert to Float
Converts input to float data.

Sound

Volume
The volume of the sound. This value, even if animated will be reflected in the waveform.
Mute (speaker icon)
The strip will not produce any sound output.
Pitch
Coefficient of playback speed. This value will affect length of the strip, that will not be represented in the timeline.
Pan
Used to pan the audio from left and right channels. Only works for mono sources. Values can be between -2 and 2, where 0 means front/center, -1 means to the left and 1 to the right. In case of multichannel audio (rear speakers) you can pan to those with the higher values: -2, 2 is back. So this value basically represents the angle at which it’s played.
Display Waveform
Display an approximate waveform of the sound file inside of the sound strip. The waveform reflects strip volume and it’s animation using keyframes.
Mono
Mixdown all audio channels into a single one.

Time Panel

Reference

Panel:Sidebar region ‣ Strip ‣ Time

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).
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 has adjusting the strip handles.
Hold Offset Start/End
Offset of the uncut strip content.
Playhead
Position of the Playhead relative to the start of the active strip.

Source Panel

Reference

Panel:Sidebar region ‣ Strip ‣ Source

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 this can be updated instead of re-create 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 Strip ‣ Inputs ‣ Paths/files.
MPEG Preseek
Movie strip only – Use Preseek field to tell Blender to look backward and compose an image based on the specified amount of previous frames (e.g. 15 for MPEG-2 DVD).
Color Space
To specify the color space of the source file.
Alpha mode

If the source file has an Alpha (transparency) channel, you can choose:

Straight Alpha or Premultiplied Alpha

Stream index
Movie strip only – For files with several movie streams, use the stream with the given index.
Resolution
Resolution of the active strip image output.

Options for Sound Strips

Sound
Data-block menu to select a sound.
Path
Path to the sound file used by this data-block menu.
Pack
Pack sound into the blend-file.
Caching
Sound file is decoded and loaded into the RAM.
