Blackmagic RAW (.braw): The Ultimate Guide to the Next-Gen RAW Video Format

Digital cinema production has historically forced filmmakers to choose between the post-production flexibility of raw sensor data and the manageable file sizes of intermediate codecs like ProRes or DNxHR. Blackmagic RAW (BRAW), identifiable by its .braw file extension, solves this tradeoff. Developed by Blackmagic Design, BRAW is a hybrid, visually lossless video codec that combines the color depth, dynamic range, and non-destructive control of RAW capture with the processing speed and compression efficiency of traditional video containers.

1. What is a BRAW (.braw) File?

A .braw file is a video clip recorded in the proprietary Blackmagic RAW format. Unlike uncompressed RAW formats (such as CinemaDNG, which store every frame as an individual raw image file inside a folder), a BRAW clip is saved as a single container file with embedded high-fidelity audio, timecode, and comprehensive sensor metadata.

BRAW achieves its performance advantage through an innovative partial de-mosaic architecture. Instead of pushing the entire compute-heavy debayering process to desktop software during editing, compatible camera hardware performs the initial stage of de-mosaicing in real time. The resulting partially processed sensor data is packaged alongside the sensor’s unique calibration profile, allowing editing software to complete the pipeline with minimal CPU and GPU strain.

2. Key Characteristics of Blackmagic RAW (.braw)

Core Strategic Advantages:

1. True Non-Destructive Post-Production: Adjust camera ISO, color temperature, tint, exposure offset, and color space at any time without baking in adjustments or degrading the image.
2. Lightning-Fast Playback: Accelerated by modern instruction sets (AVX, AVX2, SSE4) and GPU APIs (Metal, CUDA, OpenCL) for real-time multi-stream 4K/6K/8K timeline playback without rendering proxies.
3. Flexible Sidecar Metadata: Allows editors to save non-destructive color grade metadata in external .sidecar JSON files that override embedded values without rewriting the camera master file.

3. In-Depth Technical Features of BRAW

A. Intelligent Hybrid De-Mosaicing

Traditional camera sensors capture light through a Bayer color filter array, requiring complete debayering on your computer’s CPU/GPU. BRAW offloads noise management and partial de-mosaic processing directly to the camera hardware. The decoding application then renders the final picture using the sensor’s raw characteristics, cutting computer decoding overhead by more than 50%.

B. Dual Encoding Modes: Constant Bitrate vs. Constant Quality

Blackmagic RAW provides two distinct recording methodologies to match specific production budgets and storage constraints:

• Constant Bitrate (5:1, 8:1, 12:1, 18:1): Allocates a fixed data rate relative to the raw sensor output. This guarantees predictable file sizes and record times, making it the preferred choice for commercial shoots, live sports, and broadcast work.
• Constant Quality (Q0, Q1, Q3, Q5): Employs variable bitrate compression that scales dynamically with visual complexity. Highly detailed frames (such as ocean waves or foliage) receive extra data, while simpler frames are compressed tightly to maximize visual fidelity.

C. 12-Bit Non-Linear Color Gamut & Gen 5 Color Science

BRAW utilizes a custom non-linear 12-bit color pipeline that preserves extreme shadow details and highlight roll-offs across high-dynamic-range scenes. Combined with Generation 5 Color Science, BRAW reproduces accurate skin tones, smooth color gradations, and expansive dynamic range matching the quality of high-end Hollywood camera packages.

D. Comprehensive Embedded and Sidecar Metadata

Every .braw file encapsulates frame-by-frame metadata including focal length, iris settings, focus distance, camera gyro data, ISO, white balance, and slate info. If you tweak these values in post-production, changes can be saved to an external, human-readable .sidecar file, ensuring pristine preservation of the original camera media.

4. How to Create and Record BRAW Files

BRAW files are created natively through compatible hardware capture devices and external digital recorders:

Method 1: Using Native Blackmagic Cameras

1. Power on any Blackmagic digital film camera (such as Blackmagic Cinema Camera 6K, Pocket Cinema Camera 4K/6K/6K Pro, URSA Mini Pro 4.6K/12K, or PYXIS 6K).
2. Open the Record setup menu on the camera touch display.
3. Select Blackmagic RAW as the primary recording format.
4. Choose your desired compression mode:
   • Select Constant Bitrate (e.g., 5:1 or 8:1) for predictable storage calculations.
   • Select Constant Quality (Q0 or Q5) for variable quality-driven workflows.
5. Record directly to an internal CFast 2.0 / SD UHS-II card or an external USB-C NVMe SSD.

Method 2: External Recording with Blackmagic Video Assist 12G HDR

1. Connect a supported mirrorless or cinema camera (such as select cameras from Panasonic LUMIX, Nikon Z series, Sigma fp, or Fujifilm) via HDMI 2.0 or 12G-SDI to a Blackmagic Video Assist 12G HDR monitor/recorder.
2. Enable HDMI/SDI RAW Output in your camera’s internal setup menu.
3. Set the Video Assist recorder to capture incoming sensor signals as 12-bit .braw clips onto high-speed media.

5. How to Open and Play BRAW Video Files

Because Blackmagic Design offers a free, cross-platform SDK, .braw files can be played and edited across all major platforms (Windows, macOS, and Linux):

1. Blackmagic RAW Player (Free Official Standalone Viewer)

The fastest way to preview BRAW clips without opening an editor:

1. Download and install the free Blackmagic RAW SDK & Utility Suite from the official Blackmagic Design support site.
2. Launch Blackmagic RAW Player.
3. Open any .braw file to preview video playback, inspect embedded slate metadata, and view real-time frame rates.

2. DaVinci Resolve & DaVinci Resolve Studio (Native Support)

DaVinci Resolve provides native, zero-configuration support for BRAW:

1. Open DaVinci Resolve and import .braw clips into the Media Pool.
2. Drag clips into the timeline.
3. Open the Color workspace and navigate to the Camera RAW palette tab.
4. Set Decode Using to Clip to adjust ISO, exposure, color temperature, highlight recovery, and color gamut directly on the sensor data.

3. Adobe Premiere Pro & After Effects (via Blackmagic RAW Plugin)

1. Installing the Blackmagic RAW desktop installer automatically adds the official BRAW plugin to Premiere Pro and After Effects.
2. Import .braw media straight into the Project panel.
3. Access the Effect Controls panel to modify raw camera settings via the Master Clip tab.

4. Apple Final Cut Pro (FCP)

Mac users can import and edit BRAW directly in Final Cut Pro by installing third-party workflow extensions and decode plugins such as Color Finale Transcoder or the official Blackmagic RAW plugin for macOS.
