Free Voice Over Video Maker

There are several platforms and software available where you can do a voice-over for a video:
No.1 - CapCut: CapCut is a popular video editing app that offers built-in voice recording capabilities for creating voice-overs directly within the application.
No.2 - Audacity: Audacity is a free audio editing software that allows you to record and edit your voice-over separately. You can then import the voice recording into a video editing software to synchronize it with your video.

The decision of whether to create the voiceover or the video first depends on the specific project and workflow preferences. In some cases, it may be more efficient to create the voiceover first, as it sets the pacing and tone for the video, allowing the visuals to be synchronized accordingly. However, in other instances, it may be preferable to create the video first, and then record the voiceover to match the timing and visual cues of the footage. Ultimately, it is a matter of personal preference and the requirements of the project.

Step 1. Install the CapCut app from the App Store and open it on your iPhone;
Step 2. Import the video you want to add a voiceover to by tapping the "+" button and selecting the video from your device's gallery;
Step 3. Tap on the video timeline to select it, then tap on the "Sound" icon at the bottom of the screen;
Step 4. Tap on the "Microphone" icon to start recording your voiceover. Speak into the device's microphone while watching the video;
Step 5. Tap the "Stop" button to end the recording. You can preview the voiceover and make adjustments if needed;
Step 6. Tap the "✓" button to save the voiceover.
