===== Clips (Video, Audio and Images) =====
 
The {{Icon|kdenlive-add-clip}} button (Add Clip) brings up the '''Add Clip''' Dialog where you can choose video, audio or still image clips to add to the [[Special:myLanguage/Kdenlive/Manual/Projects_and_Files/Project_Tree|Project Bin]].
 
[[File:Add clip dialog.png|450px|center]]
 
The button {{Icon|view-previews}} labeled 1 toggles File Preview on and off (applies to image files only). The slider labeled 2 adjusts the size of the preview icons. The <menuchoice>Import image sequence</menuchoice> checkbox labeled 3 enables the import of a series of images that can be used to make a stop motion animation.
 
You can add other types of clips by choosing a clip type from the menu brought up from the drop down button next to the  {{Icon|kdenlive-add-clip}} button.
 
[[File:Kdenlive Add other clip types.png|center]]
 
===== Color clips =====
 
Color clips are images composed of a single color that can be added to the Project Tree. They can be useful to provide a background on which to place titles.
 
Add color clips by choosing <menuchoice>Add Color Clip</menuchoice> from the drop down button next to the {{Icon|kdenlive-add-clip}} button.
 
This brings up the '''Color Clip''' dialog from which you can choose a color and a duration.
 
[[File:Add color clip.png|center|200px]]
 
Clicking <menuchoice>OK</menuchoice> adds the clip to the project tree. The clip can then be dragged to the timeline. The duration of the color clip can be adjusted on the timeline.
 
===== Title clips =====
 
See [[Special:myLanguage/Kdenlive/Manual/Titles|Titles]]
 
===== Image Sequence clips =====
 
Image Sequence clips are clips created from a series of still images. The feature can be used to make an animation from a collection of still images or to create a slideshow of still images. To create the former, use a short frame duration; to create the latter, use a long frame duration.
 
To create an image sequence clip, choose <menuchoice>Add Image Sequence</menuchoice> from the <menuchoice>Add Clip</menuchoice> drop down list.
 
[[File:Create slide show clip.png|center|300px]]
 
From the '''Image Sequence''' dialog choose <menuchoice>Filename pattern</menuchoice> as '''Image selection method'''.
 
Browse to  the location of the images which will make up your image sequence and select the first image. The subsequent images that are to be used in the slide show will be selected based on some sort of filename algorithm that predicts what the next image file name should be.
 
For example, if the first image is <tt>100_1697.jpg</tt> then the next will be <tt>100_1698.jpg</tt>, etc.
 
Select an appropriate frame duration &mdash; this defines how long each image be displayed.
 
Then hit <menuchoice>OK</menuchoice>.  A video file made up of all the images in the folder from which you selected the first frame file from will be added to the Project Tree.
 
You can then drag this video to the timeline.
 
Center crop: automatically fills the output video frame with the images while maintaining their aspect ratio by zooming the image and cropping equal amounts from each edge until can fill the full frame. Without this option, the image will not be zoomed, but black bars will appear when the photo orientation or aspect does not match the video's.
 
Animation: adds preset slow smooth pan and zoom effects also known as the Ken Burns Effect. You can choose no animation, pans only, zooms only, or a combination of pans and zooms. Each option also has a low pass filter to reduce the noise in the images that may occur during this operation. Low pass filtering is much slower, so you should preview without it, and then enable it to render.

''Proxy clips'' create a lower-quality transcode of the original footage for use in real-time rendering in the project monitor.  This allows for a smoother editing experience even on slower computers with High Definition footage.  When rendering, by default, the original quality footage is used and not the proxy footage. For example, Video decoding of H.264 or H.265 clips, requires a lot of computing power to decode and could cause playback ''stutter'' when rendering effects in real time.
 
Proxy clips can be enabled/disabled for the current project in the Project Settings (<menuchoice>Project</menuchoice> &rarr; <menuchoice>Project Settings</menuchoice> &rarr; <menuchoice>Proxy</menuchoice> &rarr; <menuchoice>Enable Proxy Clips</menuchoice>).
 
To enable proxy clips by default for new projects, go to <menuchoice>Settings</menuchoice> &rarr; <menuchoice>Configure Kdenlive</menuchoice> &rarr; <menuchoice>Proxy Clips</menuchoice> &rarr; <menuchoice>Enable Proxy Clips</menuchoice>.

* Duration: Change the clip duration. If the duration is shorter than the clip duration, then the clip is '''cropped'''. If the duration is bigger than the clip duration, then the last image is repeated until the new duration is over.
''Proxy clips'' are one of the most useful inventions for editing if you are not working on a ultra high-end machine. The trick is that the original clips are replaced by clips with lower resolution clips, with a less complex codec. Video decoding, e.g. of H.264 clips, requires a lot of computing power, but computing power is required for rendering effects in real-time. If insufficient is available, replay will ''stutter''. Proxy clips will require hardly any computing power at all, which allows fluent replay.
* Aspect ratio: Change the clip aspect.
* Proxy clips: Enable a proxy clip for this clip. See [[Special:myLanguage/Kdenlive/Manual/Projects_and_Files/Clips#Proxy_clips|Proxy clips]].

Clips

See also Clip Menu.

Clips (Video, Audio and Images)

The button (Add Clip) brings up the Add Clip Dialog where you can choose video, audio or still image clips to add to the Project Bin.

The button labeled 1 toggles File Preview on and off (applies to image files only). The slider labeled 2 adjusts the size of the preview icons. The Import image sequence checkbox labeled 3 enables the import of a series of images that can be used to make a stop motion animation.

You can add other types of clips by choosing a clip type from the menu brought up from the drop down button next to the button.

Color clips

Color clips are images composed of a single color that can be added to the Project Tree. They can be useful to provide a background on which to place titles.

Add color clips by choosing Add Color Clip from the drop down button next to the button.

This brings up the Color Clip dialog from which you can choose a color and a duration.

Clicking OK adds the clip to the project tree. The clip can then be dragged to the timeline. The duration of the color clip can be adjusted on the timeline.

Title clips

See Titles

Image Sequence clips

Image Sequence clips are clips created from a series of still images. The feature can be used to make an animation from a collection of still images or to create a slideshow of still images. To create the former, use a short frame duration; to create the latter, use a long frame duration.

To create an image sequence clip, choose Add Image Sequence from the Add Clip drop down list.

From the Image Sequence dialog choose Filename pattern as Image selection method.

Browse to the location of the images which will make up your image sequence and select the first image. The subsequent images that are to be used in the slide show will be selected based on some sort of filename algorithm that predicts what the next image file name should be.

For example, if the first image is 100_1697.jpg then the next will be 100_1698.jpg, etc.

Select an appropriate frame duration — this defines how long each image be displayed.

Then hit OK. A video file made up of all the images in the folder from which you selected the first frame file from will be added to the Project Tree.

You can then drag this video to the timeline.

Center crop: automatically fills the output video frame with the images while maintaining their aspect ratio by zooming the image and cropping equal amounts from each edge until can fill the full frame. Without this option, the image will not be zoomed, but black bars will appear when the photo orientation or aspect does not match the video's.

Animation: adds preset slow smooth pan and zoom effects also known as the Ken Burns Effect. You can choose no animation, pans only, zooms only, or a combination of pans and zooms. Each option also has a low pass filter to reduce the noise in the images that may occur during this operation. Low pass filtering is much slower, so you should preview without it, and then enable it to render.

Proxy clips
Activating proxy clips

Proxy clips create a lower-quality transcode of the original footage for use in real-time rendering in the project monitor. This allows for a smoother editing experience even on slower computers with High Definition footage. When rendering, by default, the original quality footage is used and not the proxy footage. For example, Video decoding of H.264 or H.265 clips, requires a lot of computing power to decode and could cause playback stutter when rendering effects in real time.

Proxy clips can be enabled/disabled for the current project in the Project Settings (ProjectProject SettingsProxyEnable Proxy Clips).

To enable proxy clips by default for new projects, go to SettingsConfigure KdenliveProxy ClipsEnable Proxy Clips. See also the Project Settings page



As soon as proxy clips are enabled, they can be generated for specific project clips in the Project Tree widget via the context menu Proxy Clip. After you select Proxy Clip for a clip, a job will start to create the clip. You can view the progress of this job by looking at the little gray progress bar that appears at the bottom of the clip in the Project Tree — see picture. Clicking Proxy Clip again disables the proxy for this clip.

You can multi-select clips in the Project Tree and select Proxy Clip to start a batch proxy clip generation job which will queue up multiple proxy clip generation jobs.


Once the proxy clip creation has completed, the proxy clip will appear with a P icon in the Project Tree.
When rendering to the final output file, you can choose whether to use the proxy clips as well. It is disabled by default , but for a quick rendering preview it is useful.


Clip Properties

You can display and edit clip properties by selecting a clip in the Project Bin and choosing Clip Properties from the Project menu or from the right-click menu. Or by turning on the display of clip properties the ViewClip Properties check box.

File Info

The File Info tab (Maginifying Glass Icon) displays information about the file.

Properties

The Properties tab (Pen Icon) displays advanced properties of the clip where you can select a check box and then force the clip to take the property you specify. For example, you can use Aspect ratio to tell a clip that seems to have forgotten it was 16:9 ratio that it really is 16:9 ratio.

Advanced Clip property options are:

  • Duration: Change the clip duration. If the duration is shorter than the clip duration, then the clip is cropped. If the duration is bigger than the clip duration, then the last image is repeated until the new duration is over.
  • Aspect ratio: Change the clip aspect.
  • Proxy clips: Enable a proxy clip for this clip. See Proxy clips.
  • Frame rate: Change the clip frame rate. See Wikipedia Frame rate.
  • Scanning
  • Field order
  • Disable autorotate
  • Threads
  • Video stream
  • Audio stream
  • Colorspace
  • Full Luma range

Markers

You can use the Markers tab to add markers for certain points in the source file that are important. However, it is probably easier to add markers to your clips via the Clip Monitor because that allows you to preview the file at the location where you are adding the marker.

Once markers are put in your clip, you can access them in the Clip Monitor by right-clicking and selecting Go To Marker (see picture.) Also note how the markers appear as red vertical lines in the Clip Monitor (see yellow highlighted regions in the picture.) You can turn on the display of the marker comments in the timeline too (see Show Marker Comments).


Markers can also be added to clips on the timeline. Right-click the clip and choose Markers -> Add Marker. Markers added this way also appear in the clip in the Project Bin.

Metadata

You expect this to show any meta data that is contained in the clip. Does not appear to work.

Analysis

You can view and delete motion vector data that is associated with the clip from here. This is data created by Auto Mask - Motion Tracking

Button 1 Will delete the selected analysis data, Button 2 will allow you to export the data (semi colon delimited text file), Button 3 will allow you to import analysis data.

Generators
Counter

This generates a counter timer clip in various formats which you can put onto the timeline.


You can choose to have the clip count up by checking that option, otherwise it will count down by default. The No Background option will remove the background from the counter leaving only the grey background without the lines.

To change the size and position of the clip, you can add an effect to the clip on the timeline such as the pan and zoom or the transform.

White Noise

This generates a video noise clip — like the "snow" on an out-of-tune analogue TV. In ver 17.04 it generates audio white noise as well as video snow.

Color Bars

This generator came in to Kdenlive around ver 17.04. Generates a color test pattern of various types. Including PAL color bars, BBC color bars, EBU color bars, SMPTE color bars, Philips PM5544, FuBK
