Canon EOS C70 Super 35 4K Cinema Camera

10-bit 4:2:0 video captures 1,024 shades per color channel, but chroma is subsampled at a quarter of the luma resolution, meaning less color data is stored. This format offers better color depth than 8-bit 4:2:0 and is commonly used for consumer-grade recording and streaming, but it has limitations for intensive color grading and keying.

10-bit 4:2:2 video captures 1,024 shades per color channel, with chroma sampled at half the horizontal resolution of luma, which helps preserve more color detail than 4:2:0. This format strikes a balance between color accuracy and file size, making it ideal for professional broadcast, recording, and moderate color grading work where efficiency and quality are both important.

12-bit Log recording captures over 68 billion colors while using a logarithmic gamma curve to preserve more dynamic range and highlight/shadow detail in a visually compressed form. This combination provides maximum flexibility in post-production, especially for color grading and matching footage across different lighting conditions.

8-bit 4:2:0 video stores 256 shades per color channel and reduces color resolution by sampling color information (chroma) at one-quarter the rate of brightness (luma). This format is efficient for compression and streaming but offers limited flexibility for color correction and grading compared to higher bit-depth and chroma subsampling formats.

AVC (Advanced Video Coding), also known as H.264, is a widely used video compression standard that balances high video quality with efficient file sizes, making it ideal for streaming, broadcasting, and video storage. It achieves compression by reducing redundancy within the video data, which helps maintain quality while keeping file sizes manageable for various platforms and devices.

Canon Cinema RAW Light is a compressed RAW video format developed by Canon to offer the flexibility and image quality of RAW while significantly reducing file sizes compared to traditional uncompressed RAW. It captures 12-bit sensor data with high dynamic range and color fidelity, preserving critical information for advanced color grading, HDR finishing, and visual effects workflows. Despite being compressed, Cinema RAW Light retains the key benefits of RAW—such as adjusting exposure and white balance nondestructively—while being more storage- and workflow-friendly. It is designed for efficient data handling in professional cinema production and is supported by major post-production platforms like DaVinci Resolve, Adobe Premiere Pro, and Final Cut Pro.

HEVC (High Efficiency Video Coding), also known as H.265, is a video compression standard that offers improved compression efficiency over its predecessor, AVC, by reducing file sizes while maintaining high video quality. It is widely used for 4K streaming, video conferencing, and storage, as it provides better compression for high-resolution videos without sacrificing detail.

XF-AVC is a professional video codec developed by Canon, based on the H.264 compression standard, designed for high-quality video recording with efficient data management. It supports both Intra-frame (All-I) and Long GOP compression, offering flexibility between high-quality, edit-friendly footage and more storage-efficient files. XF-AVC supports 4K and HD video, 10-bit color, and high dynamic range, making it suitable for a wide range of professional production workflows, including cinema, broadcast, and corporate video. The codec offers robust compression for optimal storage without sacrificing image quality, and is compatible with major editing software, making it ideal for high-end production environments where flexibility, performance, and post-production quality are essential.

All-Intra (All-I) compression records each frame as a complete image, meaning every frame is independently encoded without relying on data from other frames. This results in higher quality and more predictable editing performance, making it ideal for post-production workflows that require precise frame-by-frame manipulation.

Long-GOP (Long Group of Pictures) is a video compression technique that reduces file size by storing only the changes between frames rather than every individual frame. It uses a combination of I-frames (intraframes with full image data), P-frames (predicted frames), and B-frames (bidirectional frames) to efficiently compress video over a sequence of frames. This structure allows for significantly smaller file sizes compared to All-Intra (All-I) compression, which encodes every frame independently. However, Long-GOP can be more processor-intensive to edit, since reconstructing any given frame may require decoding multiple surrounding frames.
