Film Festival Subtitle Requirements — The Complete Guide for 2026

Sundance, Tribeca, Cannes, Berlinale, Venice, SXSW & TIFF — File Formats, Language Requirements, DCP Specs & SDH Standards

Getting your film into a major festival is only half the battle. Getting your subtitles right before the deadline is the other half — and it is the part that trips up filmmakers more often than any other technical delivery requirement.

Every major film festival has its own subtitle specifications. The format that Sundance accepts is not the same as what Berlinale requires. What Cannes demands for DCP delivery differs from what Tribeca needs for its streaming screener. And the SDH requirements that Netflix built into its delivery specs have now influenced how many festivals handle accessibility captioning. This guide covers the subtitle requirements for the seven most important international film festivals — with specific format requirements, language specifications, DCP and file delivery standards, and SDH/accessibility requirements for each.

Sundance Film Festival — Subtitle Requirements

Sundance is the most important independent film festival in the United States, and its technical delivery requirements are among the most detailed of any festival. For the 2026 edition, Sundance required DCP for all in-person festival exhibition alongside a ProRes file for online screenings.

Sundance subtitle specifications:

• DCP must include both a Closed Caption version and an Open Caption version
• ProRes files must also include Closed Captions
• Non-English language films must deliver a version with standard English subtitles AND a separate version with English SDH subtitles (Subtitles for the Deaf and Hard of Hearing)
• Subtitles must be delivered as part of the DCP — not as a separate sidecar file
• Feature film delivery deadline: January 5, 2026. Short film delivery deadline: December 19, 2025

The Sundance SDH requirement is notable — it goes beyond standard subtitle delivery and requires that your English-language subtitle track specifically includes speaker identification, sound effect descriptions, and music cues in addition to dialogue. This is not a standard subtitle file and requires specialist SDH production. Gotham Lab provides SDH subtitle files meeting all Sundance technical specifications from our in-house New York City team.

Tribeca Festival — Subtitle Requirements

The 2026 Tribeca Festival — the festival’s 25th anniversary edition, running June 3–14, 2026 in New York City — requires all project submissions via a password-protected streaming URL rather than physical DCP for the selection process. This makes Tribeca’s subtitle requirements for submission screeners more flexible than most major festivals.

Tribeca subtitle specifications:

• Subtitle language: English required for all non-English language films
• Submission format: password-protected streaming URL — no physical DCP required for submission
• Work-in-progress submissions must be clearly marked WIP or Rough Cut
• Links must remain active and accessible through June 5, 2026
• Closed captioning is required for all accompanying audio/podcast video content submitted for accessibility

Because Tribeca accepts streaming screeners rather than DCPs for the selection process, many filmmakers submit with burned-in subtitles or SRT/VTT sidecar files compatible with their streaming platform. However, if your film is selected, full DCP delivery with proper subtitle tracks will be required for exhibition. Plan subtitle production for both screener submission and DCP delivery from the start.

Cannes Film Festival — Subtitle Requirements

The Cannes Film Festival — including both the main festival and La Semaine de la Critique (Critics’ Week) — has specific subtitle requirements tied to DCP delivery format. Cannes is the most technically demanding festival on this list for subtitle specifications.

Cannes subtitle specifications:

• DCP format required for all official selections — subtitle export must be XML
• Films in French or English may submit without subtitles if that is the source language
• Films in all other languages must have either French or English subtitles
• La Semaine de la Critique (Critics’ Week) requires French or English subtitles for all non-French/English films
• For La Semaine de la Critique short and feature submissions: subtitles must be integrated (burned-in) into the image — separate subtitle files are not accepted
• Competition films and Berlinale Special Galas receive double subtitles in English and German

The burned-in subtitle requirement for La Semaine de la Critique submissions is a critical technical detail that catches many filmmakers off guard. Unlike most festivals that accept separate subtitle sidecar files alongside the video, Critics’ Week requires the subtitle text to be permanently embedded into the picture file. This means subtitle production must be completed before the final video export — not as a post-export step.

Berlinale — Subtitle Requirements

The Berlin International Film Festival accepts DCP and QuickTime ProRes as approved media formats. Berlinale’s subtitle requirements vary by section, with Competition films receiving special treatment.

Berlinale subtitle specifications:

• Selection screener must include English subtitles for all non-English language films
• Competition and Berlinale Special Gala films are presented with double subtitles in English and German
• All other sections: all non-English language films must be subtitled in English for festival presentation
• If German subtitles are available alongside English, dual subtitles will be used in other sections where possible
• Closed captions in German or English and audio description versions (via the GRETA app) should be flagged to the festival if available
• DCP delivery deadline: January 28, 2026 for the 2026 edition
• DKDMs (Distribution KDMs) must be valid from delivery through February 23, 2026

Berlinale’s commitment to accessibility is growing — the festival actively requests that filmmakers notify them if German or English closed captions or audio description versions are available, so the festival can expand its accessibility services. If your film has been produced with accessibility in mind, flag this to the Berlinale Film Office upon selection.

Venice Film Festival — Subtitle Requirements

The Venice Film Festival is the oldest film festival in the world, and its subtitle requirements reflect both its European location and its international audience.

Venice subtitle specifications:

• All foreign language films (non-Italian) must include Italian subtitles
• Italian-language films where speakers have strong accents or dialects may also include Italian subtitles
• Italian films with no strong accents or dialects: closed captions should be in English, supplied as DCP in XML format
• DCP format required for all exhibition

Venice’s Italian subtitle requirement is the most distinctive on this list — it is the only major festival that requires the local language (Italian) rather than the international default (English) as the primary subtitle language for foreign films. If you are submitting to Venice, Italian subtitle production must be planned in advance. Gotham Lab provides Italian subtitle translation and DCP-ready subtitle files for Venice submissions.

SXSW Film & TV Festival — Subtitle Requirements

The South by Southwest Film & TV Festival in Austin, Texas accepts a wide range of content types and has clear subtitle and captioning requirements for both in-person DCP exhibition and online screener delivery.

SXSW subtitle specifications:

• DCP required for in-person exhibition
• English subtitles required for all non-English language films
• Closed captions required for all screening formats
• SDH subtitles strongly recommended for accessibility compliance
• ProRes or H.264 accepted for online screener submission alongside DCP for exhibition

SXSW’s emphasis on closed captioning across all screening formats reflects a broader industry shift toward mandatory accessibility at festivals. The 2026 SXSW submission deadlines ran from August through October 2025, with the festival taking place in March 2026.

Toronto International Film Festival (TIFF) — Subtitle Requirements

TIFF is North America’s largest film festival and one of the most important launching pads for Oscar-season films. Its technical requirements are comprehensive and uncompromising.

TIFF subtitle specifications:

• DCP required for all in-person festival exhibition
• English subtitles required for all non-English language films
• Subtitle files must be embedded within the DCP — not delivered as separate sidecar files
• Closed captions and SDH tracks strongly recommended for accessibility — TIFF is actively expanding its accessibility programming

ProRes or high-resolution H.264 accepted for selection screeners

What Are SDH Subtitles and Why Do Festivals Require Them?

SDH stands for Subtitles for the Deaf and Hard of Hearing. SDH subtitles go beyond standard dialogue translation to include speaker identification, descriptions of significant sound effects, and music and audio cues — providing deaf and hard-of-hearing viewers with the same complete audio experience as hearing viewers.

Sundance’s requirement for a separate English SDH subtitle track alongside standard English subtitles reflects the growing accessibility standard across the industry. Netflix, Amazon Prime Video, and Disney+ all require SDH tracks for every piece of content on their platforms. Film festivals — particularly US festivals subject to ADA guidelines — are moving in the same direction. Producing SDH subtitles is a specialist task that goes beyond standard subtitle translation. The SDH file must include properly formatted speaker IDs (e.g. [JOHN]), sound effect descriptions (e.g. [door slams]), and music cues (e.g. [tense orchestral music]) alongside all dialogue — timed precisely to the picture. Gotham Lab produces SDH subtitle files meeting all major festival and streaming platform specifications from our in-house New York City team.

DCP Subtitle Delivery — What Filmmakers Need to Know

A Digital Cinema Package (DCP) is the standard delivery format for theatrical exhibition — including film festivals. Unlike a consumer video file, a DCP is a collection of files in a specific directory structure, and subtitles within a DCP must be formatted as a separate XML subtitle file that is referenced by the DCP composition playlist (CPL).

Key DCP subtitle technical requirements that apply across most festivals:

• Font: festival DCPs typically use an Arial or similar sans-serif font at a minimum 42-point size for readability at theatrical distances
• Position: subtitles must be positioned within the safe subtitle area — not within the bottom 10% of the frame — to avoid being cut off on different screen sizes
• Reading speed: maximum 17 characters per second is the standard for most festivals — the same as Netflix’s requirement
• Line length: maximum 42 characters per line for standard DCP subtitle tracks
• Format: SMPTE-compliant XML subtitle files within the DCP structure

One critical point: DCP subtitle files are separate from the picture and audio files within the DCP. They are not burned into the image. This means they can be updated after the DCP is created — but only if you have access to the original subtitle XML files and can repackage the DCP. This is a significant production advantage compared to festivals that require burned-in subtitles.

Frequently Asked Questions — Film Festival Subtitle Requirements

Q: Do I need subtitles if my film is in English?

For most festivals, English-language films do not need foreign-language subtitles. However, Sundance and SXSW require Closed Captions and/or SDH tracks even for English-language films — both for accessibility compliance and for deaf and hard-of-hearing audiences. Always check each festival’s specific requirements for English-language films.

Q: What is the difference between closed captions and subtitles for film festival submissions?

Subtitles translate dialogue into another language for viewers who can hear but do not understand the source language. Closed captions transcribe all audio — dialogue, sound effects, speaker IDs, and music cues — in the same language as the film, for deaf and hard-of-hearing viewers. SDH subtitles combine both: they translate dialogue into another language AND include accessibility descriptions. Most major festivals require at minimum standard subtitles for non-English films; Sundance and SXSW additionally require closed captions and/or SDH.

Q: Can I use burned-in subtitles for my DCP?

Some festivals — notably La Semaine de la Critique at Cannes — specifically require burned-in subtitles integrated into the image file. However, most major festivals prefer or require separate subtitle XML files within the DCP structure, as burned-in subtitles cannot be updated after the DCP is created. For festivals that accept either format, separate subtitle files within the DCP are always preferable for flexibility.

Q: What subtitle format does Berlinale require?

Berlinale accepts DCP and QuickTime ProRes. For DCP delivery, subtitles should be formatted as SMPTE-compliant XML subtitle files within the DCP structure. The selection screener requires English subtitles for all non-English films. Competition films receive double subtitles in English and German — German subtitle production is handled by the festival for Competition selections.

Q: How much does it cost to produce festival subtitle files?

Gotham Lab’s subtitling rates start from $6 per minute for translated subtitle files. SDH subtitle production is priced per project based on runtime and language. DCP-ready XML subtitle file production is available as part of a complete festival delivery package. Contact us at info@gothamlab.com or +1 347-587-8110 for a free project quote.
