Kdenlive comes with different effects that can be applied to the audio and others that can be applied to the video. This can be applied to the full clip and, by defining different ttorial you can adjust the volume, for example, to start muted, then increase progressively, then continue at normal level, then decrease progressively and become muted, continue muted for a time and start again progressively From lines 3 to 34, you set up directories that the animation is going to land in and the variables you will later need to create the transition’s frames.

Some video tutorials were made for simple tasks in Kdenlive. Transitions are normally used to smoothly change from one clip to another or from one scene to another.

The problem is more logistic, because now you need not just one image, but a whole sequence of PNG images.

It is all about calculating the ideal sizes for the animation frames, the transition frames, and the initial positions of all the moving parts. These powerful features are explained in detail in this pagebut for the purpose of this quickstart guide, we’ll focus on an easy one, the crossfade transition but see the warning at the top of this page!

The timeline gives you a visual representation of your project, and shows when clips start, when they end, and in the case of overlapping clips, which one will actually be used.

The visible frame also has a square in its center, and both squares are kdenpive by a line. This will recenter your mask in the visible frame. You have a title clip in track 0 with a crossfade transition between it and the other clip in track 1. Click on the magnifying glass and select a idenlive scale or click on the ruler and drag left. Before starting your first project, you are asked for a name, a working directory and a video size.


You can then edit the clip from the timeline.

Below is the Custom Transitions video associated with this article. To split a clip, the normal way is to place the timeline cursor at kdenlove splitting point you can adjust the exact position by playing with the “Next frame” and “Previous frame” buttons in the “Timeline Monitor”. Kdenlive will insert all the intermediate steps, between your two keyframes, making your mask go gradually from completely transparent and invisible, to completely opaque, showing the second clip on the bottom track.

Say, for example, you want a mask to go from completely invisible to completely visible. The complexity comes not so much from the theory, since the principles are the same. But you can change this behaviour by selecting others in the Track Selection List.

Although the example of a static image as shown in Figure 1 used a black kdenpive, the mask doesn’t have to be black.

VOBbut for the moment we are not going to use these options. The loop that runs from lines 21 to 29 finds the width of the widest animation frame. In the following dialog you can select to create a DVD menu or not.

Put your image in the topmost track, the clip you want to use as a mask on the track under that, and the clip you want to show through the hole made by your mask on the bottom-most track. To apply tutorlal customized transition, open the two clips that you want to use the transition on in your Kdenlive project; then, load the frame and chroma sequence of images that the customtransition.

Simply move the mouse cursor to the beginning or end of the clip you want to resize. By this, you’ll remove the clip from the timeline but it still appears in the “Project Tree” list.

You’ll see immediatly how the colours in your clip dissapear and are replaced by grey tones! For the purpose of this Quickstart guide, and in order to show you the basic Kdenlive functionalities, we’ll work with two of your clips, adding a title at the beginning, a video transition between them and a video effect to a part of one clip. The timeline can contain multiple tracks. You do this because, before creating the final transition frames, you have to fit your animation image mostly outside the frame on the right in the first few transition frames and mostly outside the frame on the kdenlove in last few.


If the box and the text have the same colour, they may interfere!

Align your clips with the animation and mask sequences to create a perfect transition. In particular, there is no longer a crossfade transition. In that instance, I used a Pacman animation with a transparent area and a blue, chroma area to make Pacman gobble up the first clip and lead in to the second. To set up your transition in Kdenlive, you’ll need four video tracks: And behind the “Parameters” tab, you’ll notice kdenllive one titled “Keyframes”.

What you want is the Xor option. By default, Kdenlive gives you three video tracks to work with. This will make your mask fade in. To know more about keyframes and how to work with them see this page. With this option only the clip in the current track will be split. Views Read Edit View history. Sometimes you may need to delete maybe because you let your video-camera or TV-capture-device run too long or maybe to apply uttorial video effect to only a part of a clip. Maybe the easier one is to select the clip or clips that you want to delete, and press the “Delete” button on your keyboard.

A new window like this will be presented:. Resizing a clip changes its in and out points.
