Color Tag
|
|
Besides the set of :ref:`Default Strip Colors <sequencer-strip-colors>`
|
|
strips can also be given 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
|
|
If enabled the strip will not produce any output.

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 Frames
|
|
Strip is played backwards starting from the last frame in the sequence.

Sound
|
|
=====
|
|
|
|
.. reference::
|
|
|
|
:Panel: :menuselection:`Sidebar --> Strip --> Sound`
|
|
|
|
Working with sound is documented further at :ref:`bpy.types.SoundSequence`.
|
|
|
|
.. _bpy.types.SoundSequence.volume:
|
|
|
|
Volume
|
|
The volume of the sound.
|
|
This value, when animated and with the :menuselection:`View --> Show F-Curves` option activated,
|
|
is drawn on the strip as a dark section that follows the animation curve.
|
|
The value is also reflected in the waveform.
|
|
|
|
.. _bpy.types.SoundSequence.pan:
|
|
|
|
Pan
|
|
Used to pan the audio between speakers in multichannel audio.
|
|
Only works for mono sources. The number of audio channels can be configured in
|
|
the :ref:`Audio Output <render-output-video-encoding-audio>` settings.
|
|
For stereo output panning works from left (-1) to right (1). When
|
|
the output uses more than two channels, values can be between -2 and 2,
|
|
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:
|
|
-2, 2 is back. This value basically represents the angle at
|
|
which it's played if you multiply the value by 90 degrees.
|
|
For smooth animation you can assign values outside the soft bounds,
|
|
since the angle wraps around over multiple rotations.
|
|
|
|
.. _bpy.types.SoundSequence.show_waveform:
|
|
|
|
Display Waveform
|
|
Display an approximate waveform of the sound file inside of the Sound strip.
|
|
The waveform reflects strip volume and its animation using :doc:`keyframes </animation/keyframes/introduction>`.
|
|
|
|
Clipping audio, i.e. values over 100% amplitude, will be shown in red in the waveform.
|
|
|
|
.. _bpy.types.Sound.use_mono:
|
|
|
|
Mono
|
|
Mixdown all audio channels into a single one.
|

Time

|
====
|
|
|
|
.. reference::
|
|
|
|
:Panel: :menuselection:`Sidebar --> Strip --> Time`
|
|
|
|
The Time panel is used to control source and timeline position of the strip.
|
|
|
|
Lock (padlock icon)
|
|

|
|
|
|
.. _bpy.types.Sequence.show_retiming_keys:

|
Changes the starting frame number of the strip, which is the same as selecting and moving the strip.
|
|
|
|
.. _bpy.types.Sequence.frame_final_duration:
|
|
|
|
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.
|
|
|
|
.. _bpy.types.Sequence.frame_offset_start:
|
|
.. _bpy.types.Sequence.frame_offset_end:
|
|
|
|
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.
|

Source
|
|
======
|
|
|
|
.. reference::
|
|
|
|
:Panel: :menuselection:`Sidebar --> 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 :menuselection:`Strip --> Inputs --> Change 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.
|
|
|
|
The list of color spaces depends on the active :ref:`OCIO config <ocio-config>`.
|
|
The default supported color spaces are described in detail here:
|
|
:ref:`Default OpenColorIO Configuration <ocio-config-default-color-spaces>`
|
|
Alpha Mode
|
|
If the source file has an Alpha (transparency) channel, you can choose:
|
|
|
|
:term:`Straight Alpha` or :term:`Premultiplied Alpha`
|
|
Stream Index
|
|
Movie strip only -- 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 only -- The frame rate encoded into the video file.
|
|
If this value does not match the scene :ref:`Frame Rate <bpy.types.RenderSettings.fps>`
|
|
the perceived speed of the media will be wrong unless the speed is
|
|
:ref:`changed <video_editing-change_fps>` to account for the difference in frame rate.
