Marketing and training teams producing scripted avatar-led business video at scale
Creative teams and filmmakers generating original cinematic footage from text prompts
Runway and Synthesia both carry the "AI video" label but they solve fundamentally different problems. Synthesia wins this comparison for the primary use case of business video production: it delivers photorealistic AI avatars with a 9.1/10 blind realism score, Brand Kit enforcement for consistent team output, and enterprise-grade features (SSO, SCORM export) that Runway does not offer. Runway excels at generative video — creating short cinematic footage from text prompts using its Gen-3 Alpha model — a capability Synthesia does not have. According to Wyzowl's 2025 Video Marketing Statistics, 85% of enterprise marketing teams now use video as a primary channel, driving demand for both categories.
In our 30-day test, Synthesia produced consistent, on-brief marketing and training videos with measurable brand compliance. Runway's Gen-3 Alpha outputs were visually impressive for creative and cinematic work — but not suited to scripted business video with presenter narration, which is the dominant enterprise use case. The tools serve different buyer profiles: Synthesia is for marketing and L&D teams producing structured video content at scale; Runway is for creative teams and filmmakers generating original visual footage. G2's AI Video Software Report ranks Synthesia first for enterprise customer satisfaction in the AI video category. See our Synthesia review for the full benchmark.
Short answer: pick Synthesia for avatar-led business video, training content, and brand-compliant marketing at scale. Pick Runway if your use case is generative cinematic footage for creative projects — not structured business video.

Frequently Asked Questions
Is Runway better than Synthesia for AI video?
They solve different problems. Synthesia is better for structured business video — scripted avatar narration, brand compliance, training delivery, and marketing content at scale. Runway is better for generative creative footage — producing cinematic clips from text or image prompts using Gen-3 Alpha. For enterprise marketing and L&D teams: Synthesia wins. For creative directors and filmmakers needing original footage: Runway is the more relevant tool.
Can Runway create videos with an AI presenter like Synthesia?
No — Runway does not have an AI avatar or presenter feature. Runway's generative capabilities (Gen-3 Alpha) create short cinematic footage from text prompts, but there is no way to produce a scripted video with a photorealistic on-camera narrator. Synthesia's entire product is built around this specific feature: 230+ photorealistic avatars that deliver scripted narration with lip-sync accuracy. For presenter-led business video, Synthesia has no equivalent in Runway.
Which is cheaper: Runway or Synthesia?
Both start around $15-18/mo at the first paid tier. Runway Standard is $15/mo (625 credits/month). Synthesia Starter is $18/mo (annual, 10 videos/month). Runway has a free plan (125 credits). The pricing models are not directly comparable because Runway sells generation credits and Synthesia sells video production slots. For business video production, Synthesia's per-video pricing is more predictable. Runway's credits are consumed quickly on longer generations.
Does Runway support enterprise features like SSO and SCORM?
No — Runway does not offer SSO (single sign-on) or SCORM export. Runway has a Team plan for collaborative creative work but does not target enterprise L&D or corporate training workflows. Synthesia offers SSO, SCORM export for LMS delivery, team workspaces with role-based permissions, and SOC 2 Type II certification. For enterprise compliance and training delivery requirements, Synthesia is the only appropriate option between the two.
What is Runway Gen-3 Alpha and how does it compare to Synthesia?
Runway Gen-3 Alpha is a text-to-video and image-to-video generative AI model that produces short (up to 16-second) cinematic footage clips from prompts. The visual quality is impressive for creative applications — atmospheric footage, B-roll, and experimental visual effects. Synthesia does not have a generative video feature; it converts scripts to avatar-narrated presenter videos. The two capabilities are complementary, not competing: Gen-3 Alpha for original footage creation, Synthesia for scripted business video production.
Which tool is better for multilingual corporate video?
Synthesia is far stronger for multilingual corporate video. Synthesia supports 140+ languages with photorealistic avatar narration — produce a video once and switch the avatar's spoken language and subtitles without re-recording. Runway does not have narration or language features; it generates visual footage only. For global enterprise teams producing training or marketing content in multiple languages, Synthesia is the only relevant option between the two platforms.
