Rotate Video by 45 Degrees in Kdenlive

Rotating a video by an exact angle in Kdenlive is a straightforward process when using the Transform effect. This guide provides a quick, step-by-step walkthrough on how to apply the Transform effect to your video clip, locate the rotation parameter, and input the precise value of 45 degrees to achieve a perfect diagonal tilt.

Step 1: Add the Video to the Timeline

Drag and drop your video clip from the Project Bin onto the timeline at the bottom of the Kdenlive interface.

Step 2: Locate the Transform Effect

Go to the Effects tab (usually located in the left-hand panel). In the search bar at the top of the Effects tab, type Transform.

Step 3: Apply the Effect to the Clip

Drag the Transform effect from the search results and drop it directly onto your video clip in the timeline. Alternatively, select the clip in the timeline and double-click the Transform effect in the list.

Step 4: Open the Effect Properties

Click on your video clip in the timeline to select it. Look at the Effect/Composition Stack panel (typically located in the top-right or top-center area of the screen) to view the adjustable settings for the Transform effect.

Step 5: Input the Precise Rotation Value

In the Transform properties, locate the Rotate parameter.

• Important Note: In Kdenlive, the rotation value is measured in tenths of a degree. To rotate the video by exactly 45 degrees, you must multiply the angle by 10.
• Click on the numerical input field next to the Rotate slider.
• Type 450 (which represents 45.0 degrees) and press Enter.

Step 6: Adjust Scale (Optional)

Rotating a rectangular video by 45 degrees will leave black, empty triangles in the corners of the frame. If you want the video to fill the screen entirely: * Adjust the Size (or Scale) parameter in the same Transform menu. * Increase the value until the black edges are no longer visible in the Project Monitor.
