When you are operating at the high end of modern cinema production, every single frame matters, and corrupt files can mean disaster for a project. The widespread shift toward uncompressed, high-bitrate RAW codecs has fundamentally transformed visual storytelling; giving directors of photography and colorists unprecedented dynamic range and post-production flexibility. However, this imaging headroom comes with an uncompromising operational requirement: relentless, sustained data throughput. Files get larger, more quickly, and our tools have to keep up.
At Glyph, we’ve spent a tremendous amount of time, effort, and resources ensuring our products have the best possible sustained write performance and offer reliability that creators can count on.
That is why we are thrilled to announce that Glyph Capture+ CFexpress Type B 4.0 Memory Cards (in 1TB, 2TB, and 4TB capacities) are now officially RED APPROVED.
Glyph Capture+ cards are officially listed across RED’s site, camera pages, and technical support documentation as fully authorized media for the RED V-RAPTOR, and KOMODO-X.

The Ultimate Stress Test: Why RED Approval Means Everything
Not all memory card certifications are created equal. RED Digital Cinema cameras are renowned for placing some of the highest I/O demands in the entire industry on storage media to ensure the best performance and thermal management. Capturing full-raster, high-frame-rate REDCODE® RAW generates massive, unthrottled data streams that must be serialized, buffered, and recorded without a fraction of a millisecond of delay.
To earn official RED Approval, a card cannot simply pass a synthetic benchmark on a lab bench. RED subjects media to an exhaustive, multi-tier evaluation process designed to test cards well beyond the physical, thermal, and bandwidth conditions they will encounter on production sets in the real world.
Specifically, RED’s engineering team tests for:
- Unthrottled Sustained Write Speeds: Verifying that write performance never dips below the camera's peak bandwidth requirements across 100% of the card’s capacity; over and over, for hundreds of hours.
- Extreme Thermal Stability: Modern compact camera bodies like the KOMODO-X and V-RAPTOR package incredible processing power into tight, sealed media bays. Cards must manage thermal dissipation efficiently without thermal throttling or overheating the camera interior.
- Firmware & Protocol Integrity: Ensuring a flawless digital handshake between the camera’s real-time operating system and the card’s memory controller, preventing communication dropouts, corrupt metadata, or file-system errors.
"If a card fails any of these criteria for even a frame, it doesn't get approved. Period."Beyond RED: Performance Reserve for the Entire Cinema Ecosystem.
This level of scrutiny is precisely why earning RED Approval is so meaningful to us. At Glyph, we aren't just an engineering company pushing specs and performance to next-generation levels; we are creators ourselves.
We know what it feels like to be on set when the light is fading, the talent is locked in, and everything rides on that single roll of the camera. We know that behind every byte of data is someone’s creative vision, hours of preparation, and a production budget that cannot afford a dropped frame or a corrupted card. We understand the importance of fast-data transfers, so you can not only finish on time but do so reliably.
That shared passion for the creative process is deeply ingrained in who we are. It translates directly into our engineering philosophy: reliability above all else.
Glyph Capture+ CFexpress Type B 4.0 cards pass RED’s stringent authorization by pairing premium flash memory with our SteadyIO™ thermal architecture, providing the write speeds that you need coupled with our intelligent power-loss protection to keep you shooting reliably. Because high-end cinema and photo workflows demand sustained write performance that strains conventional media, Capture+ far exceeds those requirements, giving creators a vital buffer of safety, reliability, and peace of mind.
- Cinema & Hybrid Performance: Effortlessly handles high-bitrate RAW and Intra-frame video on cinema rigs (Sony BURANO, Blackmagic PYXIS/URSA) and instantly clears deep continuous RAW buffers on hybrid flagships (Nikon Z8/Z9, Canon R5/R5 C).
- Universal & Future-Proof: Built on the CFexpress 4.0 standard with full CFexpress 2.0 backward compatibility to protect your investment.
Whether shooting on a classic Canon DSLR or the latest cinema camera, Capture+ delivers overengineered, dependable media at a highly competitive price point. That means you don’t need to spend more to get the best. We build cards designed to fade into the background, allowing you to focus on the art rather than the gear. To back that up, every Capture+ card includes our 5-year hardware warranty, featuring overnight advanced replacement and 5-year Level-1 data recovery.
