Demystifying Video: A Guide to Video File Formats

In the world of video production, understanding the language of file formats and codecs can seem intimidating. For clients, it's not essential to know every technical detail, but understanding the basics can help you appreciate the complex process of turning raw footage into a polished final product. The key is to recognize the difference between acquisition formats, which are used to capture the highest quality footage in-camera, and delivery formats, which are optimized for sharing your final video with the world.

Acquisition Formats: The Digital Negative

Acquisition formats are all about capturing as much data from the camera sensor as possible.

These formats are less compressed, which means they produce very large files, but they give our editors maximum flexibility to manipulate the color, lighting, and other elements in post-production.

• Apple ProRes (.mov): A professional intermediate codec that is lightly compressed and widely used for multi-layered and complex edits. It’s known for its high quality and can be used on both Mac and Windows systems.

• Blackmagic RAW (.braw), REDCODE RAW (.r3d), Sony X-OCN, and Cinema RAW Light: These are various proprietary RAW formats that act like a digital negative. They capture an incredible amount of image data and provide the most flexibility for color correction and exposure adjustments during the editing process.

• MPEG-4 AVC/H.264 (.mp4 or .mov): While also a common delivery format, this is often used in professional cameras as an acquisition format. It’s highly compressed, resulting in smaller file sizes, but it offers less flexibility than the RAW or intermediate formats listed above.

Delivery Formats: The Final Product

Once a video is edited, it needs to be exported in a delivery format that is optimized for its final destination. These formats are highly compressed to ensure they can be played back on a wide range of devices without consuming excessive bandwidth or storage.

• MP4 (MPEG-4 Part 14) with H.264 or H.265 codec: This is the most versatile and widely used delivery format on the planet. H.264 provides an excellent balance of quality and compression for web playback and social media platforms like YouTube, Vimeo, and Instagram. The newer H.265 (HEVC) codec offers even better compression, making it ideal for 4K and 8K content.

• MOV (QuickTime) with H.264 or Apple ProRes codec: This is the primary format for the Apple ecosystem. A high-quality ProRes MOV file is perfect for a master file to be used for long-term archival purposes, allowing us to create new, more efficient copies as technology evolves.

• WebM with VP9 or AV1 codec: This is an open-source, royalty-free format designed specifically for HTML5 web video, making it an ideal choice for streaming platforms like YouTube and Netflix. The newer AV1 codec is an even more efficient and future-proof option for web streaming.

• MXF (Material Exchange Format): This is a professional container format used for broadcast and large-scale production workflows. It is optimized for robust media workflows and is a standard for broadcast delivery.

• MPEG-2 (.mpg): A legacy format that remains the standard for physical media, such as DVD and Blu-ray discs.

• Streaming Protocols (HLS, MPEG-DASH, SRT): These aren't file formats but protocols that dynamically adjust video quality based on a viewer's network speed. This is essential for a professional live-streaming experience, as it minimizes buffering and ensures smooth playback.

Understanding Video Files

Navigating these formats and codecs is a critical part of the post-production process. Having an experienced team that is not only familiar with these formats but also has a proven track record of delivering them is paramount. We have extensive experience delivering digital files to a variety of destinations, from TV networks and Video-on-Demand platforms to a wide range of online streaming services.
