Channel localisation: is another language worth it?
Channel localisation gives more people a way into your programmes. It also brings invoices for translation, rights, quality review and distribution. Before commissioning a dub, decide which audience you expect to reach, how they will find the channel and what their viewing could earn.
Language access clearly gets used. YouTube reported that, as of December 2025, more than 6 million viewers watched at least 10 minutes of auto-dubbed content daily. That is a platform-reported consumption figure, without evidence of incremental FAST revenue or a channel’s return on localisation spending.
Start with an audience you can actually reach
Choose a territory, audience and distribution partner. A large population of speakers tells you little about carriage, programme discovery or advertising demand. Existing viewing by territory, partner enquiries and advertiser commitments provide a more useful starting point.
Language and country are different dimensions. A Spanish-language service might reach viewers across several countries, each with different rights and commercial terms. Geography alone also tells you little about someone’s preferred audio language.
Check whether the audience wants dubbing, subtitles or both. The European Commission’s 2024 Eurobarometer summary reported that 53% of respondents preferred subtitles to dubbed films, based on 2023 interviews. That EU-wide preference cannot settle the choice for your genre and target market. Test it with the people you want to serve.
Choose the operating model before the budget
Adding a selectable audio track preserves the underlying pictures and schedule. A dedicated regional feed lets you change scheduling, promotions and commercial inventory, with additional work to run it. Confirm what the receiving platform accepts before buying either approach.
Subtitled catalogue test
Selected programmes + translated subtitles and discovery metadata. A limited on-demand test can reveal interest; its results need further testing for a scheduled channel.
Alternative audio on the same feed
One video schedule + selectable language tracks. Confirm partner ingestion, player selection and reporting for each language.
Separate regional channel
A dedicated output + local schedule, branding and commercial arrangements. Budget for ongoing operation as well as launch.
These are alternative operating choices. A new audio track does not automatically create another channel listing or grant access to another territory.
YouTube’s multilingual feature documentation illustrates the same-video approach and reporting by audio language. Ask your linear or FAST partner what equivalent reporting it provides. If language-level revenue is unavailable, record that limitation in the forecast.
Clear the rights and test the delivery
Have the rights owner or qualified adviser confirm the proposed languages, territories, platforms and licence windows. Check permission for translation, dubbing, promotional edits and any proposed use of synthetic voices. Existing agreements may cover these activities; verify their scope before spending.
WIPO’s Berne Convention summary identifies translation, adaptation and broadcasting among protected rights, subject to applicable limitations and exceptions. Possessing the master file provides no answer to those clearance questions.
Put native-language review into the production plan, including names, meaning, timing, on-screen text and programme metadata. AI-assisted dubbing still needs an accountable reviewer and a correction process.
Delivery has its own acceptance criteria. Apple’s HLS guidance covers language signalling and continuity for alternative audio and subtitles. Test the destination devices, audio selection, fallback behaviour and transitions through programme junctions and advertising. A track that exists in your master still has to reach the viewer correctly.
Compare the full cost of channel localisation
Include rights, dubbing or subtitles, quality review, artwork, electronic programme guide metadata, marketing and operating support. Spread one-time launch expenditure over an explicit evaluation period, and allow for new episodes and corrections. Delivery costs can grow with viewing.
Use receipts after partner and advertising-technology deductions. Avoid subtracting those shares twice. The example below uses invented assumptions in US dollars, solely to explain the calculation. These are neither Evrideo prices nor market benchmarks.
A worked break-even example
Assume monthly fixed incremental costs of $6,000, including rights, localisation, review and operations. That total includes a $12,000 launch cost spread over 12 months. Publisher net advertising receipts average $0.030 per viewer-hour, before variable delivery costs of $0.006 per viewer-hour.
The remaining $0.024 per viewer-hour pays for the fixed costs. Break-even is $6,000 divided by $0.024: 250,000 incremental viewer-hours per month.
Contribution covers only this illustrative expansion. Existing shared costs and tax are excluded; this is not whole-company profit. Launch-cost recovery is included in the fixed-cost assumption.
Check the downside
Run a downside case. At the same viewing level, receipts of $0.020 per viewer-hour produce $6,000. Subtracting $1,800 variable costs and $6,000 fixed costs leaves a $1,800 monthly loss. Small changes in realised advertising yield can overturn the case.
Use actual monetised impressions, fill definitions and realised receipts to estimate your viewer-hour yield. Separate genuinely additional viewing from viewers who simply switched out of the original version, including any lost contribution there.
Give the pilot a decision date
Agree the trial period, budget and expansion threshold before launch. Track viewing, retention, repeat visits, language selection, net receipts and support costs. Keep a record of promotion, catalogue changes and carriage so you can explain what changed.
Compare similar titles and distribution conditions where possible. A before-and-after increase can reflect seasonality or better placement. Where the partner cannot deduplicate viewers or attribute revenue, show a range rather than claiming precision.
Assign someone to own corrections and new releases after the launch team moves on. The pilot should establish whether the audience returns and whether the additional contribution pays for a service you can keep delivering.
