Blackmagic Design · 2017
.b5i is a proprietary RAW video image format used by Blackmagic Design cameras that preserves extensive sensor data for maximum post-production control.
Key Features
- Preserves extensive original sensor data for post-production flexibility.
- Offers both visually lossless and perceptually lossless compression options.
- Allows for adjustments to white balance, exposure, and color space in post.
- Optimized for editing performance with high-resolution video.
Best For
- Maximizing image quality and flexibility for post-production.
- Shooting in challenging lighting conditions where exposure latitude is crucial.
- Maintaining precise color control and grading capabilities.
- Workflows that prioritize editing performance with RAW video data.
Less Ideal For
- Archiving finished video projects (use more standard codecs like H.264/H.265 for final delivery).

How to Open It
- Import .b5i files directly into Blackmagic Design's DaVinci Resolve (free version available).
- Utilize official Blackmagic RAW plugins for NLEs like Adobe Premiere Pro and Final Cut Pro.
- Convert .b5i files to other formats using DaVinci Resolve or specific conversion tools if needed.
What is a .b5i file?
The .b5i file extension is associated with Blackmagic RAW (BRAW), a proprietary video codec developed by Blackmagic Design. It's designed to provide the image quality of uncompressed video formats with the efficiency of compressed formats. This format is specifically used for recording video footage directly from Blackmagic cameras, allowing for a high degree of post-production flexibility. BRAW files retain a lot of the original sensor data, offering extensive control over exposure, white balance, and color grading without degrading the image quality.

Frequently Asked Questions
.b5i is a specific image format within the broader Blackmagic RAW (BRAW) ecosystem, often used for still images derived from video sequences or specific RAW camera outputs. BRAW itself is primarily a video codec, though the underlying technology is similar.
While the files can be transferred to any computer, editing requires software that supports the Blackmagic RAW codec, most notably DaVinci Resolve, or NLEs with the appropriate plugins.
Yes, .b5i files are considered RAW image files, meaning they contain minimally processed data directly from the camera sensor, offering maximum flexibility in post-production.
Technical Details
Blackmagic RAW is a container format that stores image data directly from the camera's sensor, including metadata. It uses a combination of a proprietary lossless or visually lossless compression algorithm. The file structure is optimized for speed and efficiency during editing, allowing for real-time playback and manipulation of high-resolution footage.
