Strategy and brief

Who does what
One relationship. A specialist studio behind it.
Video only earns its budget when it is tied to a page, a campaign or a stage of the sale. That part is ours. The craft is theirs.
02
Production
Script, storyboard, design, animation or filming, sound and delivery, by a studio that does nothing else. Their producers and artists make the film.

Integration

The production team
Why Zelios.
We could have hired freelancers and hidden them. We chose a studio we are happy to name.
A specialist, not a sideline
Zelios has produced video for technology and B2B companies since 2018. It is what the whole studio does: producers, art direction, illustration, 2D and 3D motion.

Process
How a production runs.
Zelios quotes two to four weeks for a typical production. Your dates are set in the proposal.
Brief and strategy
With us. What the film has to achieve, where it will run and how we will know it worked.
Script and concept
Zelios writes the script and develops the visual concept. You approve both before anything is produced.
Production
Design, animation or filming, then sound. The studio's art director and producers run it; we keep it on the brief.
Review and refinement
You see the film, we turn your feedback into clear notes and the studio refines it.
Delivery and distribution
Master film, cut-downs and resizes delivered, then built into the site, campaigns and follow-up we run for you.
Part of the system
Where video fits in our work.
Websites
A short explainer or product film on the page that has to convert, loaded without slowing it down.
Premium websitesMeta and Google advertising
Advertising creative produced for the campaign, with the variations needed to test properly.
Meta AdsLead and sales systems
Films that do part of the selling inside follow-up sequences and sales conversations.
Lead and sales systemsEvery production is scoped and quoted in a written proposal. The cost depends on length, style and the number of formats delivered. There is no package and no retainer.
Good questions
Before we talk.
Who actually makes the video?
Zelios. It is a specialist video production studio founded in 2018. We hold the client relationship, set the brief and manage delivery. Their producers, designers and animators make the film.
Did OnlineWith.ai produce the films shown on this page?
No. Every film here was produced by Zelios for its own clients. We show them, with permission, because the same team produces the video work we deliver.
Do we deal with Zelios directly?
You deal with us: one contact, one agreement. We run briefing, feedback and approvals with the studio on your behalf, so video stays part of the same plan as your website and campaigns.
What does it cost?
Each production is scoped and quoted in a written proposal. Length, style (2D, 3D or live action) and the number of cut-downs and formats are what move the number.
How long does a production take?
Zelios quotes two to four weeks for a typical production. The proposal sets your dates, including your review points.
Can video be part of a wider project?
That is when it works best. A film made for a specific page, campaign or stage of the sale outperforms one made to have a video. We plan it alongside the website, advertising and lead systems we build.
