What Runway Means for AI Video Tools
Runway isn't an alternative to Flixly. Runway Gen 4.5 and Gen-3 Turbo run inside it, which makes the usual comparison the wrong question.
TL;DR
Runway Gen 4.5 and Runway Gen-3 Turbo are both in the Flixly catalog at PREMIUM tier, alongside Pika 2, Luma Dream Machine and Luma Ray 2. So the choice is not platform against platform but model per shot. The Runway entries here do text-to-video and image-to-video; reference-to-video across thirteen models, first-to-last frame, chaining and motion transfer are elsewhere in the catalog, as are audio and lip sync.
Runway is not an alternative to Flixly. Runway models run inside it.
Runway Gen 4.5 and Runway Gen-3 Turbo are both in the catalog, at PREMIUM tier, alongside Pika 2, Luma Dream Machine and Luma Ray 2. So the framing of most comparison articles — Runway versus everything else — misses what is actually on offer.
The real question is not which platform. It is which model for this shot, and whether you want to hold accounts with four vendors to answer that.
What Runway is
A generative video company. Its models take a text prompt, or an image plus a prompt, and produce short clips. Gen-3 and Gen-4 are the generations people usually mean.
They are good at cinematic motion and have a distinctive look, which is a real thing worth wanting. They are not uniquely capable at anything structural, and several other models handle references and frame control that Runway's entries here do not.
Deliberately omitted from this article: Runway's own pricing and plan tiers. Those change, and a comparison built on stale numbers is worse than one telling you to go and check. See Runway's site comparison for the current picture.
The Runway models available here
| Model | Tier | Capabilities |
|---|---|---|
| Runway Gen 4.5 | PREMIUM | Text-to-video, image-to-video, optional reference image, 5 or 10 seconds |
| Runway Gen-3 Turbo | PREMIUM | Text-to-video, image-to-video |
Gen-3 Turbo takes prompt, duration and aspect ratio. It is the faster, older entry.
Both sit at PREMIUM, which is mid-tier — below the ULTRA models like Veo 3.1, Kling 3.0 and Seedance 2.5, and above the STANDARD entries.
What you give up by using only Runway
Not quality. Capability coverage.
Reference-to-video across models. Thirteen models here accept a character reference. If a specific face or product has to stay itself across shots, that is the mechanism, and having thirteen options rather than one matters when a particular model handles your subject badly.
First-to-last frame. Seedance 2.0 and 2.0 Fast generate the motion between two images you supply. It is the most deterministic control available, and nothing in the Runway line here does it.
Chaining for long sequences. The Long Video Generator carries each segment's finished clip into the next, so a sequence holds together rather than being assembled from independent guesses.
Motion transfer. Motion Control maps a performance from a driving video onto a character image.
Audio and lip sync in the same place. Text to Speech, Voice Cloning and Lip Sync sit alongside the video tools rather than requiring an export.
That last one is the practical difference for most people. Not that any single tool is better, but that the export-and-reimport step between video and audio disappears.
Choosing between them for a given shot
Cinematic look, straightforward motion. Runway Gen 4.5, or Luma Ray 2, which is also built around that.
Speed while exploring. Runway Gen-3 Turbo, or the Fast and Turbo variants elsewhere: Seedance 2.0 Fast at STANDARD, Kling 3.0 Turbo, Veo 3.1 Fast.
A specific character across several shots. One of the thirteen reference-capable models. Not the Runway entries here.
Exact start and end frames. Seedance 2.0 or 2.0 Fast.
A continuous sequence. Chaining, not any single model.
Test rather than trust a table. Run one real prompt through two models and keep the winner — switching is a dropdown, so it costs about a minute.
What no comparison can tell you
Generation times. They vary with load. Any article quoting seconds-per-clip measured it once.
Quality scores. There is no published cross-model metric. Tables ranking motion quality to a decimal place invented the column.
Settings that do not exist. No motion brush here, no per-region masks, no motion strength or guidance scale. Across all 37 video generation models the parameters are prompt, duration, aspect ratio and resolution, plus references, a negative prompt or first and last frames on some. Wan 2.7 is the only entry with a seed.
The short version
If you like Runway's output, use Runway's models — they are here, at PREMIUM tier, on the same credits as everything else.
The argument for a catalog is not that any one model wins. It is that the right model changes shot to shot, and switching should cost a dropdown rather than a subscription.
The full list is at Models, each generation is quoted before it runs, and pack prices are on the pricing page.
Frequently Asked Questions
What is Runway?▾
A generative video company whose models take a text prompt, or an image plus a prompt, and produce short clips. Gen-3 and Gen-4 are the generations usually meant. They are strong on cinematic motion with a distinctive look, and Runway Gen 4.5 and Gen-3 Turbo are both available in the Flixly catalog at PREMIUM tier.
Do I have to choose between Runway and Flixly?▾
No. Runway Gen 4.5 and Runway Gen-3 Turbo run inside Flixly on the same credits as every other model, so the comparison is not platform against platform. The useful question is which model suits a given shot.
What can other models do that the Runway entries here cannot?▾
Reference-to-video, supported by thirteen models, for keeping a specific face or product consistent. First-to-last frame on Seedance 2.0 and 2.0 Fast, which is the most deterministic control available. Chaining in the Long Video Generator for continuous sequences. Motion transfer through Motion Control. The Runway entries here do text-to-video and image-to-video.
Which Runway model should I use?▾
Runway Gen 4.5 for cinematic look with straightforward motion, at 5 or 10 seconds with an optional reference image. Runway Gen-3 Turbo is the faster older entry, taking prompt, duration and aspect ratio. Both sit at PREMIUM, below the ULTRA models and above STANDARD.
Is there a motion brush or per-region mask?▾
Not here. Across all 37 video generation models the parameters are prompt, duration, aspect ratio and resolution, plus references, a negative prompt or first and last frames on some models. Wan 2.7 is the only entry exposing a seed.
How do the models compare on speed and quality?▾
There is no published cross-model quality metric, and generation times vary with load, so tables quoting seconds per clip or motion quality scores invented them. Run one real prompt through two models and keep the winner; switching is a dropdown.
What is the practical advantage of using a catalog?▾
Audio and video live in one place, so the export-and-reimport step between generating a clip and adding voice or lip sync disappears. And since the right model changes shot to shot, switching costs a dropdown rather than another subscription.
