TL;DR
Open the text-to-speech tool, pick Gemini 3.1 Flash TTS, generate a 1784-character script, add video clips with Seedance 2.0, burn captions, sync audio, then export a 3-minute-12-second MP4 ready for publication.
You need a 2200-word SEO blog post on Gemini 3.1 Flash TTS ready for publication by 9 a.m. with voiceover and captions included.
Open the dashboard and select the text-to-speech tool at /dashboard/text-to-speech. Choose Gemini 3.1 Flash TTS from the model list. Paste your outline into the prompt field. Set output length to 1800 characters and voice to a neutral US male. Generate the first pass.
Draft the core script
The script comes back as a 1784-character block. Copy it into a new note. Break it into five sections of 350-400 words each. Add H2 headings that match common search queries like "how Gemini 3.1 Flash TTS works".
Link the first tool reference inside the prose: switch to the Text to Speech page to adjust speed to 1.05x and add a 200 ms pause after each sentence.
Check length and keywords
Count words in each section. Target 12 occurrences of the primary phrase "Gemini Spark SEO Blog Guide 2026" distributed naturally. Run the text through the built-in keyword density checker. Adjust until density sits at 1.8 percent.
Add visual assets
Move to the Image to Video tool. Upload three reference images sized 1024x768. Select Seedance 2.0 and set motion strength to 0.65. Generate 8-second clips for each section header. Export as MP4 at 24 fps.
Next open the Auto Captions page. Upload the clips. Choose 48-point font and burn-in captions at 0.8 seconds per line. Download SRT files for each clip.
Build the audio layer
Return to Text to Speech and generate a 45-second intro using the same Gemini 3.1 Flash TTS voice. Export as 44.1 kHz WAV. Import the WAV and the four video clips into the timeline at /dashboard/lip-sync. Align mouth movements with the audio track using the automatic sync feature set to 98 percent accuracy.
Verify sync quality
Play the timeline at 1.5x speed. Listen for drift. If any word slips more than 40 ms, adjust the offset slider by 20 ms increments and re-render the segment.
Final assembly and export
- Sign in at /auth/register if you have not already and purchase 120 credits.
- Create a new project folder named "Gemini Spark 2026".
- Import the five video clips, SRT files and WAV track.
- Add a 12-second static end card generated via Logo Generation at 1920x1080.
- Set export resolution to 1080p, bitrate 12 Mbps, and container MP4.
- Click render and note the job ID shown in the queue.
- Download the file once the status changes to complete (usually 4 minutes for a 3-minute 12-second video).
- Upload the MP4 to your CMS and embed the SRT as a separate track.
