1. Import Media: Open your preferred video editing software and import both your video clip and the music track you want to match the duration to.
2. Timeline View: Drag and drop both the video clip and the music track onto your timeline. Ensure they are synchronized at the beginning.
3. Check Durations: Double-check the durations of the video clip and music track. If the video is shorter, this guide will focus on lengthening it.
4. Select Clip: Click on the video clip on the timeline to select it. This will bring up editing options for the clip.
5. Change Clip Speed: Look for an option called "Speed" or "Playback Rate" in your software. Adjust the speed to a lower percentage (e.g., 50% or 75%).
6. Check Length: As you lower the speed, the clip's duration will automatically increase. Keep adjusting the speed until the video clip's length matches the music track's duration.
7. Review and Export: Preview your video to ensure the speed change looks smooth and natural. Once you are satisfied with the result, export the video with the lengthened duration.
Note: Lowering the speed can create a slow-motion effect, so use discretion based on your desired outcome.
Using a Video Editing App (Mobile):
1. Open App: Launch a video editing app on your mobile device (e.g., InShot, Splice, KineMaster).
2. Import Media: Import both your video clip and the music track into the app's media library.
3. Timeline View: Drag and place the video clip and the music track onto the timeline, making sure they are aligned at the beginning.
4. Select Clip: Tap on the video clip to bring up editing options.
5. Change Clip Speed: Look for an option labeled "Speed" or something similar. Adjust the clip's speed by dragging the slider.
6. Match Durations: Experiment with the speed until the video clip's duration matches that of the music track.
7. Review and Export: Preview your adjusted clip to ensure it matches the music's pace. Once satisfied, export the video to save it with the lengthened duration.
Remember that changing clip speed may affect its natural playback, so use your judgment about how much is appropriate.
