THE SHORT VERSION
Kdenlive is a free, open-source video editor. Use it to assemble clips you already have into a complete short video. Any cost or usage limits from generating those clips remain separate.
Kdenlive is a free, open-source editor maintained within the KDE community. Its quick-start manual covers importing media, arranging clips on a timeline and rendering a finished file. That makes it a useful option to consider for assembling AI clips, recorded footage or still images.
Set a small, complete brief
Our suggested exercise is a short explainer with three shots: show the subject, demonstrate one action and end on the result. Use clips you already have permission to use. AI-generated footage may have separate generation costs and usage conditions; free editing does not remove those.
Write one sentence describing what a viewer should understand after watching. If a clip does not help explain it, leave that clip out of the first cut.
Keep the project and media together
Use the official Kdenlive site for downloads. Create a project folder with separate places for footage, narration and exports. The manual recommends organizing source media alongside the project. Keep those files in place while editing so the project can continue to find them.
Choose a project profile that suits the intended output. Import your media through the Project Bin, then arrange the three clips on the timeline. Preview the sequence before adding effects. If the clips have different shapes or frame rates, check the resulting crop and motion rather than assuming they will match.
Let the sequence do the work
Trim each clip to the part that communicates the idea. Try simple cuts first. A transition is useful when it helps the viewer understand a change, but it cannot repair a confusing sequence.
If narration is needed, record your own using our free Audacity workflow. Listen to the narration against the pictures and leave enough time for the viewer to follow each action. Check that any background audio does not obscure the words.
Render a file you can actually share
Saving the project preserves your editing decisions. Rendering creates the playable video file. After rendering, open the exported file outside the editor. Watch from the first frame to the last, checking for blank gaps, clipped speech, unwanted crops and text that disappears too quickly.
Keep the editable project together with its source files for later changes. For this brief, the useful outcome is one understandable video made from existing material. Explore more practical workflows when you are ready for another task.
