Voice & Audio Generation

For layering realistic voiceovers onto video ads, adding narration to product demos, or generating audio for Remotion-rendered videos. These tools turn ad scripts into natural-sounding voice tracks.

When to Use Voice Tools

Many video generators (Veo, Kling, Seedance) now include native audio. Use standalone voice tools when you need:

• Voiceover on silent video — Runway Gen-4 and Remotion produce silent output
• Brand voice consistency — Clone a specific voice for all ads
• Multi-language versions — Same ad script in 20+ languages
• Script iteration — Re-record voiceover without reshooting video
• Precise control — Exact timing, emotion, and pacing

Cost Comparison for 100 Ad Variations

Recommended Workflow for Scaled Ad Production

1. Generate hero creative with AI (Nano Banana, Flux, Veo) — high-quality, exploratory
2. Build templates in Remotion based on winning creative patterns
3. Batch produce variations with Remotion using data (products, headlines, CTAs)
4. Iterate — use AI tools for new angles, Remotion for scale

This hybrid approach gives you the creative exploration of AI generators and the consistency and scale of code-based rendering.

Platform-Specific Image Specs

When generating images for ads, request the correct dimensions:

Include these dimensions in your generation prompts to avoid needing to crop or resize.
