Film festivals typically want H.264 for online submissions, ProRes for high-quality master files, and a digital cinema package (DCP) for cinema screenings. The one you need depends on the festival’s requirements and on how your film will be screened.
The short answer: H.264 gets your film in, ProRes protects it, and a DCP puts it on the big screen. The confusion isn’t really about the formats. It’s about timing.
At submission stage, festivals want H.264 (occasionally ProRes for a quality check). Once you’re accepted and screening theatrically, they want a DCP built to their exact specifications: resolution, aspect ratio, sound configuration, and encryption. This is where filmmakers get caught out. They assume a polished ProRes export is “good to go”, then discover days before the premiere that a compliant DCP still needs to be built. That results in a rush job that costs more and risks failure.
Building a DCP isn’t a simple export. Correct colour conversion, precise framing, accurate channel mapping, compliant packaging, and QC playback all have to happen correctly, or you risk a black screen or dead audio on premiere night. In the worst case, the screening is cancelled.
Understanding “DCP vs ProRes vs H.264” helps you avoid delivery errors, unnecessary costs, and last-minute delays. At DCP-Solutions, we create and check festival-ready DCPs that meet cinema screening specifications.

What is the difference between DCP, ProRes, and H.264?
All three formats carry picture and sound, but they store, compress, and deliver the content in different ways. Knowing the differences helps you choose the right file at every step of your post-production workflow.
| Feature | H.264 | ProRes | DCP |
| Main purpose | Online submissions and screeners | Editing and mastering | Cinema projection |
| Typical container | MP4 | MOV | Structured package containing MXF files |
| Picture compression | Usually highly compressed | High-quality, edit-friendly compression | JPEG 2000 |
| Best use | FilmFreeway and screener links | Editing, colour grading, and master files | Festival and theatrical screenings |
| Direct cinema playback | Generally unsuitable as standard cinema delivery | Only where the venue approves it | Designed for compatible digital cinema systems |
| Encryption and KDM | Not part of the standard cinema KDM workflow | Not part of the standard cinema KDM workflow | Supports cinema encryption and KDMs |
The main distinction is simple: H.264 handles submissions, ProRes supports post-production, and a DCP delivers films to compatible cinema systems. Always check the festival’s technical specifications before exporting or ordering a master.
1. H.264: The best format for film festival submissions
For online applications, an H.264 screener file is usually the most practical choice. Efficient compression keeps file sizes manageable while retaining enough visual detail for selection committees to assess your film, and festivals can stream or download it without handling a large post-production master.
FilmFreeway’s video upload guidance suggests H.264 in an MP4 container, with a maximum video bitrate of 4,500 Kbps, two-channel AAC audio at 256 Kbps, and a maximum video height of 1080 pixels. These settings are a useful starting point, but other festivals may ask for different specifications.
H.264 is also well suited to trailers, press previews, and private screener links. But the compression discards some picture information, and every time you re-compress a video you lose more quality. Always keep your original master for future delivery.
Use H.264 to:
- upload your film to an online festival platform
- share a private screener with programmers or reviewers
- send a trailer or promotional preview
- provide a reference copy for feedback.
Don’t use an H.264 screener as your final cinema master unless the venue specifically allows it.
2. ProRes: Your High-Quality Master for Post-Production
ProRes is your post-production workhorse: a high-quality intermediate (or “mezzanine”) file for editing, colour, and sound. After the edit, a ProRes master is an excellent basis for any future delivery. Apple’s ProRes codecs retain more image information than typical H.264 delivery files and are efficient for playback while editing, which is why they’re widely used for picture finishing, colour grading, sound production, and creating distribution versions.
A ProRes export sits in a MOV container, and its size depends on the codec variant, resolution, frame rate, and audio settings. It takes up more storage than a compressed screener, but it’s a far better source for creating new versions. Festivals will occasionally ask for ProRes at submission stage as a quality check, so confirm what each one wants.
ProRes isn’t automatically a cinema-ready format though. A venue may accept a ProRes file for a particular screening, but a typical DCP workflow involves additional mastering. The picture needs the right cinema colour conversion, and the soundtrack and package must meet the venue’s playback requirements.
Keep a ProRes master to:
- Preserve your finished edit at high quality
- Produce new language versions and revised cuts
- Prepare a DCP without starting from a highly compressed screener
- Create other delivery formats for broadcasters and distributors
Whenever possible, export from your final graded timeline rather than transcoding an H.264 file back into ProRes. Making a file bigger can’t put back detail that compression has already removed.

3. DCP: The standard choice for theatrical screenings
A Digital Cinema Package contains the picture, sound, subtitles where needed, and metadata for digital cinema playback. Unlike a single MP4 or MOV, a DCP is a collection of files designed to work with cinema servers and projection systems. Our guide to what a DCP is explains the basics in more detail.
A typical DCP stores its picture in MXF files using JPEG 2000 and its audio in separate MXF files holding uncompressed PCM audio. XML files organise the presentation and identify the assets. Two important components are the composition playlist (CPL), which tells the cinema system how to play the content, and the packing list (PKL), which identifies the package’s files.
Creating a reliable DCP involves more than choosing an export preset. Professional DCP mastering must account for image dimensions, aspect ratio, frame rate, colour conversion, audio configuration, subtitles, and package integrity. A package can be technically valid and still look or sound wrong if the source material was prepared incorrectly.
The Digital Cinema Initiatives specification provides the technical framework for digital cinema systems, but the correct delivery settings also depend on the festival’s instructions and the playback equipment involved.
DCP resolution, colour, frame rate, and sound
Before mastering begins, confirm these details with the festival:
- Resolution and aspect ratio: common cinema image sizes are 2K (2048 × 1080) and 4K (4096 × 2160), and the right framing and container depend on your film’s aspect ratio
- Frame rate: common DCP rates include 24 fps, though compatible alternatives depend on the cinema system and delivery specification, so check before changing your source frame rate
- Colour space: DCP mastering usually converts the graded source to the XYZ colour space used in digital cinema, and a wrong conversion can change colour and brightness
- Audio: confirm whether the venue requires stereo or surround sound, such as 5.1 or 7.1, because correct channel mapping and level checks help prevent missing dialogue or misplaced effects
- Subtitles: verify the required language, timing, and format, and whether subtitles should be burned into the picture or delivered separately.
These checks improve cinema compatibility and help you avoid technical glitches during the screening.
DCP vs ProRes vs H.264: which format should you send?
Your choice depends on where your film is in the festival process. A submission file and a theatrical delivery package aren’t interchangeable, even when they contain the same finished film.
| Delivery stage | Recommended format | What to check |
| Initial festival application | H.264 MP4, unless instructed otherwise | Bitrate, resolution, audio, and upload limits |
| Editing and final picture finishing | ProRes MOV | Codec variant, frame rate, colour, and audio |
| Festival cinema screening | DCP, unless another format is approved | Resolution, aspect ratio, frame rate, audio, and subtitles |
| Encrypted theatrical screening | Encrypted DCP plus the required KDM | Equipment certificate, venue, and playback dates |
If you’re also weighing up archive or source masters such as a DCDM, our guide to DCP vs DCDM vs ProRes explains which master each recipient needs.
Does every film festival require a DCP?
No. Some festivals screen from DCPs, some accept approved digital files, and others arrange their own playback. Read the festival’s screening rules before paying for mastering. If the organiser requests a DCP, ask whether they want it encrypted, which audio configuration they’ll accept, and how they want it delivered.
What are DCP encryption and KDM requirements?
Some venues require an encrypted DCP to control access to the film. A key delivery message (KDM) authorises compatible cinema equipment to play the encrypted content during a defined time window, and it must match the relevant equipment certificate and screening period. An incorrect certificate or date range can prevent playback, so confirm the venue’s details early and arrange the KDM before the screening deadline. Our guide to what a KDM is covers how they work in full.
How much does DCP mastering cost in the UK?
DCP mastering costs depend on running time, resolution, encryption, extra versions, delivery method, and the services you need. DCP-Solutions currently lists unencrypted 2K DCPs from £70 for films under 15 minutes to £290 for 150–180 minutes. 4K mastering, additional KDMs (£20 per extra screening venue), version files, subtitles, and delivery cost extra, and we provide a full quote before work begins.
For the full breakdown, see our guide to what affects the price of a DCP and our terms and conditions. Standard turnaround is 2–3 business days after we receive the final materials and project confirmation, and you can read more about how long DCP mastering takes. Rush services may be available on request at additional cost.
Before accepting a quote, confirm whether you need encryption, extra language versions, subtitles, closed captions, audio replacement, or physical delivery. Providing the right source files and technical requirements early helps avoid unnecessary revisions and delays.

How to avoid DCP delivery errors before your premiere
Even a beautifully finished film can have problems if its final package hasn’t been checked. Start with the festival’s technical requirements and end with a confirmed delivery. Use this checklist before sending your film:
- keep the final graded ProRes master and a separate backup
- obtain the festival’s written technical specifications
- confirm resolution, aspect ratio, frame rate, and audio channels
- check subtitle spelling, timing, and language versions
- verify the DCP package and confirm its files are complete
- test picture, dialogue, music, subtitles, and playback where possible
- arrange encryption and KDMs early if the venue requires them
- deliver before the deadline and confirm receipt with the organiser.

FAQs
What format do film festivals want?
Film festivals usually request H.264 MP4 for online submissions and a DCP for cinema screenings, although some require ProRes or other formats. Always check the festival’s delivery guidelines before exporting your film.
Is H.264 better than Apple ProRes?
Neither is universally better. H.264 creates smaller files for online screeners, while Apple ProRes preserves more image information and is better suited to editing, colour grading, and high-quality master files.
Do you need a DCP for film festivals?
Not always. You generally need a DCP for festivals that require cinema-standard playback, but some accept other formats or arrange alternative playback. Confirm the requirements for your screening before ordering a DCP.
How do you make a DCP for film festivals?
Start with your final, high-quality master, preferably ProRes, then convert it using professional DCP mastering software or a specialist service. Set the correct resolution, aspect ratio, frame rate, colour space, audio, and subtitles, then validate and test the DCP before delivery.
What is a DCP for festivals?
A digital cinema package (DCP) is a structured set of picture, sound, subtitle, and metadata files designed for playback on compatible digital cinema systems. It’s a standard format for delivering films to cinema screens and festival venues.
What should a DCP file look like?
A DCP usually appears as a folder containing several files, including picture and audio MXF files and XML files such as the Composition Playlist (CPL) and Packing List (PKL). It isn’t normally a single MP4 or MOV video, and its files should stay together as a complete package.
