Dynamic creative optimisation (DCO) on CTV automatically assembles personalised ad versions from a library of modular creative components — different product images, headlines, offers, voiceovers, or calls to action — matched to the viewer's audience segment, geography, time of day, or behavioural data. Instead of one static 30-second spot served to everyone, DCO enables dozens or hundreds of creative variations served at scale without producing each one manually. On CTV, DCO is less mature than on desktop or mobile but is developing quickly as audience data capabilities improve.
How DCO works on CTV
A DCO system works by separating the ad creative into components (background plate, product layer, offer text, voiceover, CTA) and substituting components at serve time based on data signals. For a bank advertising on CTV, the base video might show the bank's brand and product range, while the offer text, interest rate, or product type is substituted dynamically based on whether the viewer's household data suggests they are a home loan prospect, a mutual fund investor, or a credit card customer.
On CTV, the rendering approach matters. True video DCO requires real-time video assembly — the video file is constructed at serve time from modular video layers. This is technically demanding and requires DCO infrastructure that most India CTV platforms have not yet built. A simpler approach is frame-insertion DCO — a static video with dynamic overlay elements (text, product tiles, QR codes) inserted over the video at serve time. This is more widely supported and available in CTV programmatic buying via some DSPs.
Data signals that drive CTV DCO
CTV DCO uses the same audience data signals as CTV targeting: household-level demographics (IP-based), geographic data (city, postcode), time and content context (day part, content category), and first-party audience data (CRM match, prior purchase behaviour). On JioCinema, Jio Ads' household address data can drive DCO with geographic personalisation. On YouTube CTV via DV360, Google's audience data drives creative variations through Director Mix (Google's DCO tool for video).
Google Director Mix on CTV
Director Mix is Google's DCO product for YouTube video ads — available in India via DV360. It assembles video ad variations from a base video template and swappable components: an audience in Mumbai might see a city-specific offer; an audience that has previously visited the brand's website might see a retargeting message; a morning viewer might see a different product than an evening viewer. Director Mix is the most accessible and technically robust DCO product for CTV in India because it runs on YouTube's infrastructure, which is fully programmatic.
DCO on closed India CTV platforms
JioCinema and Hotstar do not offer standardised DCO products via their direct-deal buying processes as of 2025–26. Dynamic creative on these platforms requires bespoke technical integration with the platform's ad serving infrastructure — possible for major accounts but not a standard campaign execution option. Some large advertisers have run geo-localised campaigns on JioCinema with different creative variations served to different city-level audiences, but this is manual creative management rather than automated DCO.
When DCO adds value on CTV
DCO on CTV is most valuable when: the brand has a large product range with differentiated audience segments (FMCG, banking, telecom); geographic variation is significant (different offers or languages by region); the campaign has sufficient scale that personalisation lift justifies the production investment; and programmatic infrastructure exists to support dynamic serving (primarily YouTube via DV360 for India).
For most India CTV campaigns below Rs 50 lakh budget, DCO investment is not justified — the production overhead and technical complexity outweigh the incremental lift. For large-scale always-on advertisers running CTV as a primary awareness channel, DCO is worth evaluating, particularly on YouTube CTV where the programmatic infrastructure is fully developed.
