Upload RED R3D originals to Cutsio once. Cutsio creates streamable review assets, indexes every frame with Visual Intelligence, and keeps the original R3D files attached for download, conform, and finishing. The director opens a share link and watches a review stream with accurate color metadata on any device — no manual ProRes proxy render, no baked-in look file required. RED R3D is the proprietary raw format from RED Digital Cinema cameras — including the RED V-RAPTOR, KOMODO, KOMODO-X, and DSMC2 line. R3D files store uncompressed or lightly compressed sensor data with RED's proprietary wavelet compression. A single minute of 8K RED R3D at 8:1 compression can exceed 6 GB. For a standard narrative shoot generating 2–4 TB per day, the traditional workflow demands that a DIT or assistant editor manually render the entire day's footage to ProRes or DNxHR proxies before the director can review a single frame. That manual proxy render pushes the first review back by hours — sometimes an entire overnight shift. Cutsio bypasses this manual pre-transcode bottleneck. R3D ingestion is available as an enterprise add-on for qualified production accounts. Once enabled, you upload the native .r3d files, Cutsio transcodes them into streamable review assets in the cloud, indexes every frame with Visual Intelligence, and retains the original R3D files as attachments. The director sees a review stream with the intended REDWideGamutRGB and Log3G10 color metadata, and the original camera files remain untouched for the final conform. Working with raw camera footage?

The traditional RED proxy workflow is broken because it inserts an unnecessary delay between the end of the shoot day and the start of the director's review, creates file management overhead with dual versions of every clip, and forces the director to watch low-resolution proxies that hide critical focus and exposure issues. Here is what the standard RED R3D proxy pipeline looks like on a professional set: | Step | Time Required | Risk | | :--- | :--- | :--- | | Offload R3D cards to RAID | 30–60 min per card | Card corruption or data loss | | Manual transcode to ProRes 422 Proxy | 60–120 min per hour of footage | Wrong color space or gamma setting | | Organize proxies into folders | 15–30 min | File naming mismatch | | Upload to cloud or shuttle drive | 30–120 min depending on connection | Upload failure or bandwidth limit | | Director opens and reviews | Real-time viewing | Director cannot search or jump to specific content | The total delay from "card comes off camera" to "director watches footage" is typically 4 to 8 hours. On a tight indie feature or commercial shoot, that means the director cannot review the morning's work until late in the evening — and cannot make critical decisions about coverage, performance, or focus issues until the next day. Cutsio reduces this delay dramatically. As soon as the R3D card is offloaded and uploading begins, the director can start watching the first review stream clips while the rest of the card is still ingesting. The manual proxy render step on the DIT cart is eliminated. ### What are the hidden costs of managing R3D proxies? Managing R3D proxies creates three invisible costs that most productions do not account for: 1. **Storage Multiplication**: You store the R3D source (6 GB/min) plus the ProRes proxy (1.5 GB/min at 422 Proxy) — a 1.75× storage multiplier for every minute of footage. 2. **Organizational Friction**: The assistant editor must maintain a strict naming convention between the .r3d source and the .mov proxy. One renamed folder causes the entire NLE timeline to go offline. 3. **Color Decision Entanglement**: If you bake a viewing LUT into the proxy (common practice for director review), that LUT becomes "the look." When the colorist begins grading from the original R3D, the director may complain that the grade "looks different" from what they approved — even though the R3D timeline is technically more accurate. Cutsio eliminates all three costs. The review stream is generated from the original R3D, and the original files remain attached for conform. There is no separate proxy version to manage, no LUT to bake, and no relinking step. ## How does Cutsio handle RED R3D files through the enterprise add-on? Cutsio ingests RED R3D files through the enterprise raw ingestion add-on. The process generates streamable review assets with RED color metadata preserved, indexes every frame with Visual Intelligence, and keeps the original .r3d files attached for download and conform. The ingest process works as follows: 1. **Upload**: The DIT uploads native .r3d files to Cutsio from set or the DIT cart. Cutsio supports batch uploads and resumable transfers for large raw media. 2. **Cloud Processing**: Cutsio's backend transcodes the R3D files into optimized streamable review assets. The original .r3d files remain untouched and are stored as downloadable attachments. 3. **Visual Intelligence Indexing**: Simultaneously, Cutsio's Visual Intelligence engine runs computer vision models against every frame of the review stream. It identifies objects (cars, faces, weapons, props), scenes (interior, exterior, night, day), and actions (walking, talking, running, driving). This semantic index powers Visual Search across the entire R3D library. ### What RED camera models are supported? RED R3D ingestion through the enterprise add-on supports files from V-RAPTOR, KOMODO, KOMODO-X, and DSMC2 series cameras. Contact the Cutsio sales team to confirm support for your specific camera configuration and to enable raw ingestion for your production.

## How does Visual Search let the director find specific takes in a RED R3D library? Visual Search in Cutsio lets the director find any take across terabytes of R3D footage by describing what the camera saw — eliminating the need to scrub through hours of clips or rely on a DIT's scene notes. A director reviewing a day's RED footage needs to find specific moments: "Show me all the close-ups of the lead actor from Scene 24 where the lighting was golden hour." In a traditional workflow, this means scrubbing through every R3D clip from that day, reading timecode burn-ins, and cross-referencing the camera report. Visual Search replaces this entire process. The director types a description into the search bar — "master shot kitchen argument backlit" — and Cutsio returns the matching clips ranked by relevance. The search is powered by computer vision models that analyze every frame of the R3D review stream during ingestion, building a searchable index of visual content that understands objects, spatial relationships, scene types, and lighting conditions. ### Why Visual Search is critical for RED footage that has no scratch audio RED cameras are frequently used for MOS shooting — scenes recorded without synchronized audio. When footage has no scratch track, transcript-based search returns nothing. The only way to find specific moments in MOS R3D footage is by visual content. Visual Search fills this gap by understanding what the camera saw, making every frame of MOS footage as searchable as a fully transcribed interview. ## How does Cutsio's Share feature handle director review approvals? Cutsio's Share feature generates secure, password-protected review links that support frame-accurate commenting, view tracking, and approval gates — so the director can sign off on takes and scenes without downloading a single R3D file. Once the RED footage is ingested, the DIT or assistant editor creates a share link with the following configurable settings: | Setting | Purpose | | :--- | :--- | | Password Protection | Prevents unauthorized access to raw R3D footage | | Expiration Date | Automatically revokes access after the review window | | View Tracking | Shows when the director opened the link and how much they watched | | Approval Gates | Director marks takes as "Approved," "Needs Retake," or "Alternate" | | Frame-Accurate Comments | Comments are pinned to specific frames, not approximate timecodes | The director opens the link, watches the review stream, and clicks directly on any frame to leave a comment. "At 00:03:12:08 — focus is soft on this take. Flag for retake." This comment appears in the Cutsio workspace linked to the exact frame, alongside the visual context of that moment. ## How do Collections help organize RED R3D footage by scene and shoot day? Collections in Cutsio organize RED R3D footage into visual hubs grouped by project, scene, shoot day, or any custom taxonomy — making it possible to navigate a multi-terabyte RED shoot without drilling through file folders. RED shoots generate massive amounts of data. A 20-day feature shooting RED V-RAPTOR at 8K can easily exceed 60 TB of R3D files. Traditional folder structures like `SHOOT_DAY_01/SCENE_01/TAKE_01.R3D` force editors and directors to navigate visually blind — they see only file names and folder hierarchies. Collections replace this with a visual gallery. Each clip appears as a thumbnail generated from the review stream. Users can group clips by scene, star rating, or custom tags. They can share an entire Collection as a single review link, giving the director access to all relevant takes for a specific scene in one view. ### How Collections improve the DIT handoff to the editorial team The DIT's primary responsibility is to deliver organized footage to the editorial team. With Collections, the DIT creates a Collection per shoot day, adds notes to each clip (e.g., "Scene 24, Take 3 — director's preferred take"), and shares the Collection link with the assistant editor. The assistant editor opens the Collection, reviews the marked takes, and begins building the stringout — all from the review assets linked to the original R3D files. ## How does Agentic Chat let the production team query RED R3D footage conversationally? Agentic Chat in Cutsio is a conversational AI interface that answers natural language questions about RED R3D footage — such as "find all the takes where the dolly move ends on the actor's close-up" — and returns frame-exact results without manual search or folder navigation. The production team does not need to learn a complex search syntax or folder structure. They simply ask: - "Which scenes from Day 4 were shot at 120 fps?" - "Show me the takes where the car enters frame from the right." - "Are there any shots of the sunset establishing exterior?" Agentic Chat combines Visual Search (understanding visual content), metadata search (understanding camera settings), and Collection context (understanding organizational structure) to return precise results. ## How does Cutsio's Storage model work for RED R3D footage? Cutsio's Storage uses a pay-for-minutes model that decouples storage cost from file size — meaning a 100 GB R3D clip costs the same to store as a 1 GB clip, as long as they are the same duration. This is a critical advantage for RED R3D workflows. Traditional cloud storage (Google Drive, Dropbox, AWS S3) charges by the gigabyte. A 4 TB RED shoot day could cost $100–$200 per month in cloud storage alone. With Cutsio, the same shoot day costs based on the total minutes of footage — typically a fraction of the per-gigabyte cost. | Storage Model | Cost for 4 TB of R3D Footage (per month) | | :--- | :--- | | Google Drive (2 TB plan + overflow) | ~$100–$200 | | Dropbox Advanced | ~$180 | | AWS S3 Standard | ~$100–$150 | | Cutsio (pay-for-minutes) | Significantly less for equivalent duration | The review assets and original R3D files remain streamable, searchable, and shareable at all times. There is no need to download the R3D files for review — the stream is always available from the Cutsio library, and the originals are one click away when needed for conform. ## How do you maintain the RED R3D color pipeline when reviewing before the grade? Cutsio generates the review stream with REDWideGamutRGB color space and Log3G10 gamma applied during the cloud transcode, while the original R3D files remain unmodified for the final grade. When the DIT sets a look on set using RED's in-camera color tools or external software like Silverstack or LiveGrade, that look is stored as metadata in the R3D file. Cutsio applies this look metadata during the review stream generation where possible. The director sees the intended look in the review stream without it being permanently baked into the pixels of the original file. When the footage reaches the colorist, they can start from the original R3D sensor data — completely untouched — and grade from scratch or apply the on-set look as a reference. ## What is the exact workflow for sending RED R3D footage to a director using Cutsio? 1. **Offload R3D Cards**: Offload the day's RED media to your local RAID or SSD. Verify the checksums using RED's offload tools or a third-party verification tool. 2. **Upload to Cutsio**: Drag the .r3d files or folders into Cutsio's upload interface. Cutsio supports batch uploads and resumable transfers. 3. **Cloud Processing**: Cutsio transcodes the R3D files into streamable review assets, indexes visual content, and retains the original files as attachments. 4. **Create a Share Link**: Select the uploaded clips, click "Share," and configure password protection, expiration, and view tracking. 5. **Send to Director**: Copy the share link and send it via email, text, or your production communication tool (Slack, Frame.io, or similar). 6. **Director Reviews**: The director opens the link, watches the review stream, leaves timecoded comments, and marks takes as approved or needing retakes. 7. **Export Decision List**: After review, export a "selects" EDL or FCPXML that references the original R3D files. Import this into your NLE to begin the conform with only the approved takes. The total time from step 1 to step 6 is determined primarily by the upload speed. The manual proxy render step on the DIT cart — traditionally the longest bottleneck — is eliminated. ## FAQ ### Is RED R3D ingestion available for all Cutsio accounts?
