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. The Transparent background for images checkbox labeled 4 makes the process respect an alpha channel in the source images ref.

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.

色片素材

色片素材是單一顏色的圖檔可以加到專案樹裏。它們常用於充當字幕的背景。

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.

Slideshow 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.

Add Clip 旁的下拉選單選擇Add Slide Show Clip來做投影片。

From the Slideshow Clip dialog choose Filename pattern as Image selection method.

Browse to the location of the images which will make up your slideshow 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.

例如:第一張圖是 100_1697.jpg ,第二張圖將是 100_1698.jpg, 等等。

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

設定完點擊OK. 影像檔由此目錄下的所有圖片構成,您選擇的第一張影格將加入專案樹。

然後您可以把它當作影像檔拉到時間軸上。

Center crop: automatically fills the output video frame with the images while maintaining their aspect ratio by cropping equal amounts from each edge. Said another way, it removes the black bars that will appear when the photo orientation or aspect does not match the video's.

Animation動畫: 加上了常用的Ken Burns Effect特效,可以設定慢速播放及放大縮小的特效. 您可以不要動畫效果,或是只要pans , 或是只要放大縮小, 或是兩者都要. 每個選項都有低通過濾器low pass filter 來降低圖片的雜訊,這些雜訊在操作時可能發生. 低通過濾器Low pass filtering 處理速度非常慢, 所以您可以在預覽時不要選它, 在合成render時加勾選它.

代理 素材
啟用代理素材

Proxy clips are one of the most useful inventions for editing if you are not working on an ultra high-end machine. Even quite well speced PCs can struggle with High Definition footage if proxy clips are not turned on. The trick that the proxy clip feature does is that the original clips are replaced by clips with lower resolution and a less complex codec. Video decoding, e.g. of H.264 clips, requires a lot of computing power and computing power is required for rendering effects in real time. If insufficient power is available, playback will stutter. Proxy clips require hardly any computing power at all, which allows fluent playback.

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

要讓之後的新專案自動啟用代理素材, 請到 Settings -> Configure Kdenlive -> Project Defaults -> Enable Proxy Clips. 或參考 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.


素材 屬性

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.

影像 屬性

The File Info tab displays information about the file.

Properties

The Properties tab 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.

進階的短片屬性 選項 有:

  • 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

標記

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.

生成器
Counter

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

Previous versions of Kdenlive you could have the background to the counter be transparent. There may be a defect here because it appears the No Background check box does not remove the background from the counter.

Apparently you need a pan and zoom effect to make the font of the countdown smaller

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
