素材 (影片, 音訊 和 圖片)

按下新增素材按鍵後開窗讓您可以選擇影片, 音訊 和 圖片，新增到 專案樹.

標示1 的按鍵是切換檔案的預覽. 標示 2 的拉把是調整預覽檔案的大小. 標示3 Import image sequence 的選取盒表示可匯入一系列圖片來生成動畫. 標示4的 Transparent background for images 選取盒表示圖片的背景是否要透明

你可加入多種型態的素材，下拉選單在 按鍵的旁邊。

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。

選取 按鍵旁邊的下拉選單裏面的Add Color Clip來加入色片.

開窗帶出 Color clip 的設定，你可以選顏色和區間。

點擊 OK 把素材加到專案樹. 您可把它拖入時間軸。播放時間的長短可以在時間軸上調整。

字幕 素材

幻燈片素材

幻燈片素材由一系列圖片產生. 這種特性可用於製造由圖片產生的動畫或是投影片. 若是前者的話 - 可 用較短的影格時間，而後者的話可用較長的影格時間.

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

在 Slideshow clip 對話盒選擇 Filename pattern 當做 Image selection method.

Browse to the location of the images that go to make up your slideshow and select the first image that will make up the slideshow. 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 will appear for.

Then hit OK. A video file made up of all the images in the folder from where 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 cropping equal amounts from a pair of edges. Said another way, it removes the black bars that 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 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.

Proxy clips can be enabled / disabled for the current project in the Project Settings (Project -> Project Settings).

To enable proxy clips by default for new projects, go to Settings -> Configure Kdenlive -> Project Defaults -> Enable Proxy Clips. See also 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 a proxy clip. You can tell 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.

Once the proxy clip creation has completed the proxy clip will appear with a P icon in the Project Tree.
When rendering to the output file, you can choose whether to use the proxy clips as well. It is by default disabled, 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 tree and choosing Clip Properties from the Project menu or from the right-click menu.

Video Properties

Advanced Properties

The Advanced tab displays... well ... the advanced properties of the clip. You can edit the advanced properties here. For example you can use Force 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:

• Force aspect ratio
• Force frame rate
• Force progressive
• Force Field order
• Decoding threads
• Video index
• Audio index
• Force 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 using it allows you 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 time line 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 tree.

Generators

Countdown

This generates a clip of a countdown timer that you can put into the timeline.

The font number in the dialog is a font size in pixels. However Kdenlive displays the font in a zoomed in fashion and thus lower numbers appear to be lower quality. See the pic below which is a font number 10 compared to the screen shot above which is font number 576.

It appears that you need a pan and zoom effect to make the font of the countdown smaller

Noise

This generates a video noise clip - like the "snow" on an out of tune analogue TV.
