An overseas version is not a translation; it is a new communication decision.
Subtitles, voiceover, and aspect ratio for overseas TVC versions are extensions of communication strategy. Brands often request just an English version at kickoff, only to find the language, aspect ratio, and sound design unsuitable for the target market upon delivery. To avoid rework, treat the overseas version as a standalone deliverable during project initiation, not an add-on to the domestic version.
You must first answer three questions. First, which channels will carry this overseas version: broadcast TV, streaming platforms, social media, or offline event screens? Second, is the target audience native English-speaking consumers or viewers in non-English regions accustomed to English subtitles? Third, does the brand hold full rights for the overseas market, including music, likeness, font, and asset licenses? The answers directly determine subtitle language, voiceover language, and aspect ratio.
During project initiation, the production team should request an overseas distribution checklist from the brand, including platform names, screen types, duration limits, and subtitle specifications. If the brand cannot provide this, the team should proactively list items requiring confirmation and note which affect framing and post-production timelines. Do not wait until editing to discuss subtitle placement, as locked footage leaves little room for adjustment.
Finalize the subtitle plan before filming to avoid framing conflicts.
Subtitles for overseas TVC versions are not merely added in post; they impact pre-production framing and negative space. Safe title areas vary by platform: broadcasters typically require subtitles within specific margins, while streaming platforms allow more flexible placement. Crucially, subtitles must not obscure the main subject, product packaging, faces, or key actions.
Before shooting, the team should create a safe title area overlay for storyboards, to be reviewed jointly by the director, DP, and brand. This guide must indicate potential subtitle zones and shots requiring extra headroom or bottom space. If multiple language versions are planned, safe areas must accommodate the longest subtitle variant.
The standard is that eyes, logos, pricing, or key selling points must never overlap with subtitles. If overlap occurs, either adjust the framing or shorten the text. The brand must supply subtitle scripts for each market, noting display durations. The team should verify that text length suits the visual pacing, as excessive text draws viewers' attention away from the main image.
A common risk is brands retaining domestic Chinese styling, resulting in overly long English translations. Teams should advise rewriting subtitles for overseas markets rather than translating literally. Subtitles are read while voiceovers are heard; their differing rhythms prevent sharing a single script.
Voiceover choices depend on audience habits, not cost.
Overseas TVCs typically use either narrator voiceovers or character dialogue. Narration suits product demos, brand concepts, or feature explanations, while dialogue fits narrative or interactive ads. Brands must clarify if characters speak in the overseas version and whether lip sync is required on camera.
If lip movements are clearly visible, dubbing requires reshoots or CGI lip replacement, significantly increasing cost and time. A common alternative is having actors speak English on set, using location audio or ADR in post. If non-native pronunciation undermines professionalism, professional voice actors should replace original audio, though audiences may notice lip-sync mismatches.
Feasibility depends on the number of speaking shots. For one or two close-ups, reshooting or masking is viable. If multiple shots show clear lip movement, opt for subtitles with original audio instead. An exception is fast-paced editing where brief speech renders lip sync less critical, reducing dubbing risks.
Brands should prepare data on audience acceptance of dubbing in overseas markets. Some markets prefer dubbing, such as TV commercials in Spanish-speaking regions, while others favor original audio with subtitles, like Nordic countries. The production team cannot make this decision for the brand but can request competitor ads from the target market as references. If the brand lacks data, the production team should recommend conducting a small-scale audience test before finalizing the dubbing strategy.
Aspect ratio affects shooting composition and cannot simply be cropped in post-production.
Common aspect ratios for overseas TVC versions include 16:9, 4:3, 1:1, 9:16, and 2.39:1. Broadcasters and streaming platforms typically accept 16:9, vertical social media requires 9:16, square formats suit 1:1, and cinemas or premium brands may opt for 2.39:1. If the brand confirms only one primary ratio, the crew can use safe frames during filming to protect other ratios, provided all required versions are identified in pre-production.
The safest approach is to shoot in a wider aspect ratio than the final deliverable, such as capturing in 2.39:1 and cropping to 16:9 and 9:16 in post. However, this sacrifices resolution and requires recomposing shots. Alternatively, leave headroom and footroom within a 16:9 frame so the center area remains intact when cropping to 9:16. Both methods must be determined before filming; otherwise, post-production cropping may cut off heads or products.
During storyboarding, the production team should mark safe frames for both primary and backup aspect ratios on every shot. Brands must confirm publishing specifications for each platform, including aspect ratio, resolution, bitrate, and file format. Do not rely on automatic platform cropping, as it selects focus points randomly and may remove key information.
An exception applies if the overseas version targets a single platform, such as YouTube only, in which case producing just a 16:9 version suffices without additional framing. If the brand plans to deploy the same ad across multiple global platforms, filming must accommodate multiple aspect ratios, increasing compositional complexity for the Director of Photography and potentially requiring expanded lighting and set coverage.
Technical provisions for subtitles and dubbing must be made during filming.
Assets for subtitles and dubbing in overseas TVC versions must be prepared on set. For audio, if dubbing is planned, location sound may serve solely as reference, but clear reference audio is required for every shot to facilitate post-production syncing. If original audio will be retained, location recording must meet broadcast standards, including professional microphones, noise control, and backup tracks.
For subtitles, document all on-screen text during filming, including background signage, product packaging, phone screens, and prop text. This text may need replacement or removal in overseas versions; failing to log it during production necessitates costly frame-by-frame post-processing. The production team should assign a script supervisor to capture shots containing text and record its content, position, and duration.
Brands must provide a list of text elements to retain or replace in overseas versions. For example, if Chinese labels on product packaging require English equivalents, determine whether English props will be available during filming. If not, CGI replacement will be needed, requiring special on-set markers such as tracking points on the packaging.
The risk is that some brands overlook on-screen text during filming, only to discover inappropriate text in the overseas version during post-production. The production team should review all visible text before shooting and confirm with the brand which elements to keep and which to replace. If the brand cannot finalize decisions before filming, the production team should recommend avoiding close-ups of text or using blank props that can be replaced later.
Manage post-production by version and verify acceptance criteria item by item.
Post-production for overseas TVC versions requires a version management log tracking subtitle language, voiceover language, aspect ratio, duration, delivery format, and rights scope for each version. The brand and production team must jointly confirm acceptance criteria for each version rather than relying on subjective impressions like "it looks good."
Subtitle acceptance covers text accuracy, grammatical correctness, display duration, positioning, font style, and synchronization with visuals. Voiceover acceptance includes lip-sync accuracy, audio quality, mix balance, loudness normalization, and integration with background music. Frame acceptance verifies compositional integrity, retention of key information within safe areas, absence of edge stretching or distortion, and proper display across different platforms.
The production team should provide an acceptance checklist before delivery, detailing item-by-item inspection results for each version. The brand must designate a responsible person to verify every item against the checklist rather than spot-checking only a few segments. If the brand lacks internal staff proficient in the target language, external translators or native speakers should be engaged to review subtitles and voiceovers instead of relying solely on the production team's self-review.
Delivery consequences must be clearly defined. Adjusting subtitle wording after acceptance falls within standard revisions, but retranslation or replacing voice talent incurs additional costs. The production team should specify revision limits and cost boundaries in the contract to prevent unlimited post-production changes. The brand should retain source files for all versions, including subtitle project files, raw voiceover stems, mix sessions, and master files, to facilitate future versioning.
Inapplicable scenarios and when to forgo overseas versions.
Overseas TVC versions are not suitable for every project. If the brand lacks clear overseas market objectives, media budgets, or data on target audience language preferences, producing an overseas version may waste resources. In such cases, it is advisable to produce the domestic version first and initiate overseas production only after confirming distribution channels, rather than creating multilingual versions all at once.
If ad content relies heavily on local cultural references, puns, or specific social contexts that do not translate effectively, the overseas version's impact will be significantly diminished. The production team should advise the brand to assess the creative's cultural adaptability and, if necessary, recreate the script for overseas markets rather than translating it directly.
If the brand cannot secure rights for the overseas version—for example, if music licenses cover only domestic territories or talent likeness rights are restricted to domestic use—the overseas version cannot be legally released. Before project kickoff, the production team should request a rights coverage list from the brand and confirm whether additional clearances are required for overseas use.
Another exception occurs when a brand requires an overseas version on an extremely tight schedule, such as completing subtitles and dubbing within one week. If filming is complete and there are no lip-sync issues, subtitles and dubbing can be rushed through overtime, but this carries significant quality risks. If the footage contains extensive lip-sync shots or text replacements, completion within one week is virtually impossible. In such cases, we recommend adjusting the release schedule or launching a subtitled version first while delaying the dubbed version.
As a next step, we recommend starting with an overseas version requirements form.
Before launching an overseas TVC project, brands should prepare a requirements form covering target markets, distribution platforms, audience languages, subtitle copy, dubbing languages, aspect ratios, delivery formats, licensing scope, and acceptance criteria. Only with this document can the production team accurately assess shooting and post-production workloads and propose a viable execution plan.
If no requirements form exists, the production team should proactively provide a template and confirm each item with the brand. Do not skip this step, as rework costs for overseas versions far exceed those for domestic ones; once language errors or aspect ratio issues reach the delivery stage, corrections become exponentially more difficult.
We recommend prioritizing a single market, such as North America or Europe, to produce one complete version and test its performance before expanding elsewhere. Avoid producing five language versions simultaneously, as audience preferences vary by market and spreading resources too thin often compromises quality. One successful pilot version is far more persuasive than multiple rushed releases.
