How to Add a Voiceover to a Screen Recording After the Fact

You recorded a flawless product demo. The cursor movements were precise, the workflow was logical, and every click landed exactly where it should. There is just one problem: you forgot to explain what you were doing.

Or maybe you did narrate, but a loud notification interrupted your audio midway through. Or maybe your explanation of step three was rambling and unclear, and you need to redo just that section.

In any of these cases, a traditional screen recorder forces you to re-record the entire thing. The screen capture and the audio are fused together. If one is wrong, both are discarded.

This coupling is unnecessary. A precision recording tool separates the visual from the vocal, allowing you to add, replace, or refine narration after the screen capture is complete.

Three Ways to Add Voiceover in Dina

Dina treats voiceover as an independent layer on the timeline, decoupled from the screen recording. You can add narration after the fact using three distinct methods.

1. Record a Microphone Voiceover

Dina lets you record a microphone voiceover directly inside the editor. Open your project, position the playhead where you want the narration to begin, and start recording. Dina monitors your microphone levels in real time, and the resulting audio is inserted at the playhead position as a separate track on the timeline.

You can select your preferred microphone device from within the editor — no need to configure system audio settings externally. Start and stop the voiceover with a keyboard shortcut for precise, hands-free control.

2. Import an External Audio File

If you recorded narration separately — in a dedicated audio application or with an external recording device — you can import that audio file directly into Dina's timeline. The imported voiceover is placed at the current playhead position, and Dina validates that the audio duration fits within the remaining composition length.

This method is ideal for teams where one person handles the screen recording and another provides the narration, or for situations where you want to record audio in a quieter environment than where you captured the screen.

3. Generate an AI Voice

If you prefer not to use your own voice — or if you need a consistent, professional narrator across many videos — Dina includes on-device AI voice generation using Qwen text-to-speech.

Write your narration as text, select a voice (options include Ryan and Aiden), and generate the audio directly on your machine. The larger Qwen model supports eight emotion styles — neutral, calm, excited, empathetic, authoritative, playful, sad, and whisper — and three speed presets. The generated voice track is inserted into the timeline just like any other audio layer.

For even more voice options, Dina integrates with ElevenLabs. Enter your API key, browse available voices and models, preview them, and generate studio-quality narration from text.

Editing the Voiceover

Once a voiceover track is on your timeline, you can edit it independently of the screen recording:

• Adjust volume per audio slice
• Mute specific sections without affecting the overall track
• Apply smooth fades between voiceover segments
• Adjust speed per slice to match the visual pacing

The voiceover and the screen capture are separate layers. You can modify either one without affecting the other.

Frequently Asked Questions

Can I replace just part of the narration?

Yes. Dina's voiceover system operates on the timeline. You can record a new microphone voiceover for a specific section, import audio for another section, and use AI-generated voice for a third. All three coexist as independent audio layers.

Does the AI voice generation require an internet connection?

No. Dina's built-in Qwen TTS runs entirely on your device. You can generate voice tracks offline, with no data leaving your machine. ElevenLabs integration does require an internet connection, as it uses their cloud API.

Can I generate voiceovers in languages other than English?

The built-in Qwen voices are optimized for English. For additional language support, the ElevenLabs integration provides access to multilingual voices and models.

Separate the Capture From the Voice

The best screen recordings are rarely perfect on the first take. By decoupling the visual capture from the narration, you give yourself the freedom to perfect each independently — without ever re-recording a single pixel.
