What is the best AI tool for marketing videos?

Top AI Video Tools by Use Case

There's no single "best" AI video tool—the right choice depends on your specific marketing needs, budget, and production workflow. Here's what leading CMOs are using in 2025:

AI Avatar & Spokesperson Videos

Synthesia ($30-100/month) remains the market leader for enterprise video creation with AI avatars. It offers 140+ photorealistic avatars, supports 120+ languages, and integrates with marketing automation platforms. Best for: product demos, training videos, multilingual campaigns.

Video Editing & Post-Production

Descript ($24-144/month) is the CMO favorite for editing, transcription, and effects. Works like a document editor for video—edit by deleting text, and the video cuts automatically. Includes AI-powered captions, background removal, and B-roll suggestions.

Runway ($15-55/month) leads for AI-powered effects, motion tracking, and generative features. Teams use it for removing objects, extending backgrounds, and creating custom transitions.

Recommended Starter Setup

For most CMOs launching AI video in 2025:

1. Start with Descript ($24/month) for editing and captions—it's the easiest tool to adopt
2. Add Synthesia ($30/month) when you need avatar videos
3. Experiment with Pika Labs ($10/month) for social media shorts

Total: ~$64/month for a complete AI video toolkit.

Common Mistakes to Avoid

• Buying too many tools at once: Start with one, master it, then expand
• Ignoring brand guidelines: AI tools can make videos fast, but consistency requires templates
• Skipping the editing step: AI-generated videos need human polish for brand quality
• Not measuring ROI: Track video performance by platform, length, and avatar type

Bottom Line

Synthesia and HeyGen dominate for AI avatar videos, while Descript is the CMO favorite for editing and workflow integration. Most successful teams use 2-3 complementary tools rather than searching for an all-in-one solution. Start with Descript for editing, add Synthesia for avatars, and expand based on your specific use cases and volume.
