2025 is the year multimodal AI really stopped being a toy and started being part of real creative workflows. If you make videos, marketing assets, or visual content — or you ship products that lean on generated media — three names keep coming up: Runway, Synthesia, and Midjourney. They overlap, but they’re not the same tool. This article breaks down what each does best, where they fall short, pricing signals to watch, real-world use cases, and a quick playbook so you can pick the right tool for your project.
Runway — the fast, creative video studio with generative superpowers
Runway began as a toolkit for creators who wanted powerful, approachable video-editing features powered by AI. In 2024–25 they pushed hard on higher-quality generative models and smoother API access for text→video and image→video workflows. Today, Runway feels like a hybrid: part non-linear editor, part generative studio. It’s where editors go when they want to combine human timeline editing with AI magic (background removal, inpainting, frame interpolation, and text-driven clips).
Why pick Runway
-
Editor-friendly UI: Familiar timeline and keyframe controls that editors already understand.
-
Strong for short marketing videos, social clips, and creative prototyping where you’ll mix generated footage with stock clips.
-
Decent API and usage tiers for teams that want to integrate generative video into a product pipeline.
Limits & gotchas
-
Purely photorealistic long videos are still expensive and can be jittery; Runway is optimized for short-form and compositing.
-
Complex, production-grade color grading or sound design still benefits from traditional tools paired with Runway outputs.
Synthesia — avatar-driven video at scale (business-first)
Synthesia’s whole product is about turning text into a talking-head video with lifelike avatars and synced voiceovers. Its sweet spot: training videos, sales demos, localized explainers, and any workflow where you need a clean, repeatable presenter without staging a shoot. Synthesia has aggressive pricing tiers aimed at business users and a growing set of avatar and localization features; for enterprise-grade use they also offer custom avatars and localization at scale. Recently, Synthesia has been active on partnerships to improve avatar realism, including licensing deals to enhance training sets.
Why pick Synthesia
-
Fast production for presenter-style videos: script → avatar → video in minutes.
-
Built-in multilingual dubbing and captions — great for localization and internal comms.
-
Low barrier to entry for non-creatives; many companies use it to cut production time and cost.
Limits & gotchas
-
Less flexible creatively than Runway or Midjourney for stylized visuals — the format is presenter-oriented.
-
Ethical/rights considerations: avatar likeness and usage policies matter; Synthesia has explicit rules and has experimented with compensating human actors used in training.
Midjourney — image-first, now dipping into short-form motion
Midjourney made its name with highly expressive, artistically tuned still-image generation. In 2025 the platform added short-form video capabilities: users can animate generated images into 5–21 second clips with motion prompts and export options. That makes Midjourney a compelling option when you want extremely high-fidelity, stylized visuals or rapid visual exploration and are open to short, cinematic clips rather than long-form video. Midjourney’s community-first approach (Discord-based workflows) also makes it a favorite for quick iteration and idea-sparking.
Why pick Midjourney
-
Best-in-class for creative concept art, poster imagery, and stylized marketing assets.
-
New video features are excellent for animated concept teasers and motion-first social posts.
-
Strong community and prompt-engineering culture accelerate creative iteration.
Limits & gotchas
-
Video features are newer and less full-featured than Runway’s editing-centered approach.
-
Commercial licensing and copyright debates around datasets are ongoing; check usage terms and safe-use policies.
How to choose between them — a simple decision flow
-
You need a presenter video or localized training at scale → choose Synthesia. (Fast, repeatable, business-focused.)
-
You’re editing social clips, combining footage, or need timeline control + AI tools → choose Runway. (Editor-friendly, generative + compositing.)
-
You want highly stylized visuals or quick concept motion → choose Midjourney. (Art-first, flexible prompts.)
You can and often should combine them: generate a stylized background or hero image in Midjourney, composite it in Runway with a Synthesia avatar overlay, and export for social — that workflow is common.
Pricing & business signals (2025)
-
Synthesia: Starter/creator tiers and a free trial exist; business pricing emphasizes seats and minutes, with starter plans from a modest monthly fee for small teams and enterprise plans for heavy use and custom avatars. Recent pricing moves have made entry lower-cost.
-
Runway: Offers tiers suitable for hobbyists and teams; their changelog and API improvements point to self-serve usage and higher concurrency business tiers. Expect video-render costs to scale with length and complexity.
-
Midjourney: Subscription tiers (Basic/Standard/Pro/Mega) geared to image generation, and video generation is typically behind subscription access or added render fees — check current plan details for video quotas.
Always budget for render/minute costs for video: short videos can be cheap; long or high-resolution renders can add up quickly.
Legal, rights, and moderation — what to watch
All three companies are improving content policies and licensing, but the legal environment is active:
-
Model training data and rights (especially for likeness and copyrighted works) are a live issue; platforms may change training or licensing approaches quickly. Midjourney has been in high-profile copyright conversations; Synthesia has publicly tried to address actor compensation. Always read and document the provider’s license and allowed use cases.
-
Attribution & provenance: keep records of prompts, model versions, and licenses — useful if a dispute arises or for internal audit.
-
Moderation: if you generate public-facing material, build a human review step into your workflow (especially for brand-specific or political content).
Quick workflow templates
-
Marketing hero video (stylized): 1) Generate hero image in Midjourney → 2) Import to Runway, animate camera and parallax → 3) Add voiceover or Synthesia avatar for presenter layer → 4) Final color and captions in Runway → export.
-
Product explainer for global teams: 1) Draft script → 2) Generate avatar video in Synthesia with localized audio tracks → 3) Shorten/brand in Runway and add captions → publish.
Short summary
-
Runway: Best for rapid video editing, text→video and image→video workflows, and creative teams who need an editor-like experience with generative features. Great for prototyping and motion-heavy outputs.
-
Synthesia: Best for business video production using AI avatars and multilingual narration — e-learning, internal comms, product explainers. Very template-driven and easy for non-editors.
-
Midjourney: Best at high-quality still-image generation and rapidly iterating visual concepts; its newer video features (launched in 2025) make it an option for short, stylized clips and concept motion. Excellent for concept art and imagery-heavy marketing.
Final advice: start small, measure, and combine
-
Run a tiny pilot: make a 15–30 second asset in each tool and compare speed, cost, and quality. Production needs and brand fit will vary.
-
Combine tools where it plays to strengths — no single tool does everything best.
-
Keep human oversight: AI accelerates creation, but review for brand safety, accuracy, and legal risk.
