Vidu vs Runway: Craft or Throughput
Runway is a studio you drive. Vidu is a model you brief. The gap between them is mostly about how much of the work you want to do by hand.
Runway positions itself as a production environment rather than a generator: a motion brush, specified camera choreography and in-context editing, wrapped around models that generate natively at 1080p and offer a 4K upscale afterwards for extra credits. Its Gen-4.5 model burns 25 credits per second, so the 625 credits in a $12 plan buy roughly twenty-five seconds of it.
Vidu takes the other approach. Rather than giving you more handles, it concentrates on getting a usable clip out of a brief — reference conditioning to hold a subject, micro-expression performance to make a face readable. In OpenFilmo that clip costs five credits per five seconds from the same balance as everything else.
Where they diverge
Four differences that change the workflow, not just the output.
Runway: hands-on control
A motion brush, camera choreography and in-context editing let a skilled operator direct a shot precisely rather than describing it and hoping.
Runway: the credit arithmetic
At 25 credits per second, experimentation is expensive. The economics favour one carefully controlled shot over fifty exploratory ones.
Vidu: cost per usable clip
Five credits per five-second clip, from a balance shared with images and upscaling, which changes how freely you can test variants.
Vidu: brief-led rather than handle-led
References settle appearance and the prompt describes motion, so the work is in preparing inputs rather than in steering outputs frame by frame.
How to choose per project
Ask what the deliverable actually rewards.
Count how many variants you will generate
High-volume exploration and single controlled shots pull in opposite directions on cost. Estimate which one this project is before choosing a plan.
Decide whether you need to edit inside the shot
If elements have to be added, removed or changed after generation, that is a control requirement and it has a different price profile.
Prepare references properly if you go the brief-led route
Reference quality does the work that handles would otherwise do. Put the effort into two clean images rather than into prompt complexity.
Upscale once, at the end
Resolution work on finished cuts rather than per take, whichever route you take, so credits go into the version you keep.
When each one is the right tool
By whether the project rewards control or iteration.
One precisely controlled hero shot
Runway. Where a single shot has to be directed rather than briefed, the hands-on tooling earns its credit cost.
Volume variant testing
Vidu. A lower cost per usable clip matters most when most of what you generate will be discarded.
Character continuity across shots
Vidu. Reference conditioning is aimed squarely at keeping a subject recognisable across a sequence.
Editing elements inside existing footage
Runway. In-context editing of already-generated material is a capability Vidu does not claim.
Why the decision is about workload, not quality
Both tools can produce good frames. They disagree about where the skill should sit.
Runway assumes someone who knows visual language and wants to drive. It gives you handles, and handles are only worth paying for if you intend to use them — a one-line brief will not extract much from a motion brush.
Vidu assumes you want to describe and receive. It puts the preparation into references rather than into steering, which is faster for teams without a dedicated editor and weaker when a shot genuinely needs to be composed rather than requested.
The cost structures reflect that difference honestly. Runway charges by the second of its best model, which makes craft expensive and volume punishing. Vidu charges a flat rate per clip from a shared balance, which makes craft cheaper but does not give you the handles. Neither is a bargain in every scenario, and a framework that pretends otherwise is not worth reading.
Credits and plans
Generation is metered in credits, shared across every tool.
A five-second video costs 5 credits and one image costs 2. The Free plan gives you 30 credits every month with no credit card, no watermark and commercial use included. Paid plans start at $9 for 400 credits and add faster generation, parallel tasks and higher export resolution.

Frequently asked questions
Is Runway available in OpenFilmo?
No. OpenFilmo runs the Vidu models. This page compares them so you can decide which kind of tool a project needs, not to claim Runway support.
How expensive is Runway per second?
Gen-4.5 is documented at 25 credits per second, so the 625 credits included in a $12 Standard plan cover roughly twenty-five seconds of that model. Vendor pricing changes — confirm on Runway’s own pricing page.
What does Vidu cost here?
Five credits per five-second clip and two credits per image, from one shared balance. The Free plan gives 30 credits a month with no credit card and no watermark.
Does Vidu have a motion brush?
No. Vidu is brief-led: you settle appearance with reference images and describe motion in the prompt, rather than painting motion onto a frame.
Which produces longer shots?
Runway supports longer single controlled shots. Vidu’s base clips run roughly two to eight seconds, so longer sequences are assembled from beats rather than generated in one pass.
