Where each stands
Runway
Pros
- Strong reputation among working filmmakers and studios, not just hobbyist generative-video users
- Fine-grained motion control (Motion Brush, camera controls) beyond simple prompt-to-clip generation
- Frequent model updates keep output quality and clip length improving
Cons
- Credits are consumed quickly at higher resolutions and longer clip lengths, so serious use gets expensive fast
- Character and scene consistency across multiple generated clips is still unreliable, complicating longer narrative work
- The free plan's watermarked, low-credit output is really a trial rather than something usable for real projects
Synthesia
Pros
- Removes the cost and scheduling friction of filming a real presenter for every video
- Multilingual dubbing with lip sync is a genuine time-saver for global teams
- Custom avatars let a real spokesperson or employee "present" many videos without being on camera each time
Cons
- Avatar delivery still reads as noticeably synthetic on close viewing, which limits it for high-stakes brand or emotional content
- Free and entry plans cap monthly video minutes tightly, pushing serious use onto paid tiers quickly
- Limited control over an avatar's expressiveness and body language compared to a real actor
Which should you choose?
Runway is the better fit for:
- Previsualizing a shot or scene before a real production shoot
- Generating B-roll and background plates for independent film and ad work
- Restyling existing footage into a different visual look
- Removing or replacing objects in a shot without full VFX tooling
- Driving an animated character's performance from a recorded actor
- Pitching a treatment with moving reference rather than a storyboard
Synthesia is the better fit for:
- Producing employee onboarding and compliance training videos at scale
- Localizing a single explainer video into dozens of languages
- Turning existing documentation or slides into a narrated video
- Creating product demo videos without booking a presenter or studio
- Publishing training videos into an LMS as trackable SCORM packages
- Reissuing a training video after a policy change by editing the script
