Step-by-Step Guide
Input your script
Paste your script into the FluxNote editor or generate one using the AI script tool by providing a topic.
Select voice and style
Choose an AI voice for the narration and a visual style that sets the overall aesthetic of your video.
FluxNote generates the voiceover
The platform converts your script to speech using the selected AI voice and produces word-level timing data for caption sync.
Visuals and captions are assembled
FluxNote matches footage or images to each scene and overlays animated captions synced to the voiceover.
Export the finished video
Download the final MP4 video from the FluxNote dashboard and upload it to your social media channel.
Step 1: Script to Voiceover
FluxNote takes your script text and converts it into an AI voiceover using the voice you selected. The audio is generated at a natural speaking pace with proper intonation, producing a result that sounds like a professional narrator.
Step 2: Scene Segmentation and Visual Matching
FluxNote splits your script into scene segments and matches each segment to relevant stock footage or AI-generated images. The visual matching uses the content of each sentence to find the most contextually appropriate clip or image.
Step 3: Caption Generation and Sync
FluxNote generates word-level timestamps from the voiceover audio and uses them to display animated captions that sync precisely with speech. The chosen caption style is applied consistently across the entire video.
Step 4: Assembly and Export
FluxNote combines the voiceover, visuals, captions, and background music into a single portrait-format video. The final file is an MP4 ready for direct upload to YouTube Shorts, TikTok, or Instagram Reels.
Pro Tips
- Write scripts in short, punchy sentences — they produce cleaner scene cuts and tighter visual matching.
- Avoid overly complex or technical language in scripts if you want the AI visual matching to work accurately.
- Preview the video before exporting to catch any visual scenes that do not match the script content.
- Use the editor to swap out individual scenes if the auto-matched visual is not ideal for a specific segment.
- Generate multiple videos back-to-back — FluxNote's pipeline runs in parallel, so you can queue jobs.
