📝 Step-by-Step Tutorial
Step 1: Import Source Video and Extract Transcript [Timestamp: 02:27]
Import your selected source video footage into CapCut and place it onto the editing timeline. Review the footage duration and extract or transcribe the original spoken narration so you have the baseline text ready for transformation.
Step 2: Rewrite into Original Commentary with ChatGPT [Timestamp: 03:05]
Open ChatGPT and submit the original transcript with a prompt instructing the model to rewrite the content into an engaging, conversational commentary style with fresh perspective.
Prompt / Settings:
I want to make a commentary video. Here is the original script. Can you please rewrite the entire script in a natural, engaging style?
[Insert original transcript here]
Step 3: Generate the Commentary Voiceover [Timestamp: 03:35]
Copy the rewritten script into a text-to-speech platform such as ElevenLabs (or TTS Free as an alternative). Select a clear, expressive voice that fits the mood of the commentary. Ensure spacing is clean, then generate and download the synthesized audio file.
Step 4: Clean Gaps and Dead Air in Adobe Audition [Timestamp: 04:30]
Open Adobe Audition and import your generated voiceover track. Inspect the waveform for unnatural pauses or lingering silences between sentences. Slice and delete unnecessary dead gaps while keeping natural breathing cadences intact, then export the polished audio file.
Step 5: Sync Audio and Mask Existing Captions in CapCut [Timestamp: 05:16]
Open CapCut, mute or lower the volume of the original video clip, and place your edited commentary voiceover on the timeline, aligning key commentary moments with the action. If the original video contains burned-in subtitles, navigate to the Stickers panel, apply a blur sticker, and stretch it over the original text area across the duration of the clip.
Step 6: Add Auto-Captions and Visual Callouts [Timestamp: 06:28]
Navigate to the Text menu in CapCut and select Auto Captions to transcribe your new voiceover track. Choose a bold, animated caption template that highlights spoken words. Enhance viewer retention by inserting visual overlays such as circles, arrows, punch-in zooms, and motion-tracked callouts over key moments in the footage before exporting the final video.
💡 Key Takeaways & Pro Tips
- Fair Use and Monetization Compliance: Simply swapping the voiceover or burning in subtitles does not automatically make content monetizable; ensure you add significant transformative value, original insight, and have necessary permissions for third-party clips.
- Tighten Audio Pacing: Removing dead silence between sentences in an audio editor dramatically improves viewer retention and makes AI-generated speech sound far more human.
- Mask Old Captions Seamlessly: When covering existing on-screen text, use a feathered or soft blur sticker so the mask blends cleanly into the video background without distracting viewers.
