Automating Proxy Generation in DaVinci Resolve: Overnight Batches for Massive R3D Ingestion

Learn how to automate proxy generation for massive RED RAW (R3D) data dumps in DaVinci Resolve, optimizing overnight batch processing for DITs and assistant editors. For productions that want to skip the proxy step entirely, Cutsio's enterprise raw ingestion handles the transcode in the cloud.

How do you automate proxy generation for massive R3D ingestion in DaVinci Resolve?

To automate massive proxy batches, utilize the DaVinci Resolve Blackmagic Proxy Generator app, set your watch folder to the raw R3D drive, define the output format as H.265 or ProRes Proxy, and click Start to process the files overnight. For productions that want to eliminate the proxy generation step entirely, Cutsio's enterprise raw ingestion add-on accepts native R3D files and generates streamable review assets in the cloud — no manual transcode on the DIT workstation required.

When a DIT (Digital Imaging Technician) offloads 4 Terabytes of 8K RED RAW (R3D) footage at the end of a shoot day, the assistant editor cannot manually transcode clips one by one. DaVinci Resolve includes a standalone application called the Blackmagic Proxy Generator specifically for this bottleneck. You point the app to the root folder of the camera cards. The app runs autonomously in the background, scanning for new R3D files and instantly transcoding them into lightweight proxy formats. Because it runs independently of the main DaVinci Resolve interface, it can churn through massive data dumps overnight without tying up an edit bay.

Why should you use the standalone Proxy Generator instead of the Deliver page?

The standalone Proxy Generator is superior because it automatically links the generated proxies to the raw media via background metadata tracking, whereas exporting from the Deliver page requires manual relinking in the Media Pool.

In the past, assistant editors would drop all raw footage onto a timeline, export low-res MP4s from the Deliver page, and manually sync them later. This workflow is obsolete. The Blackmagic Proxy Generator creates a hidden "ProxyMedia" subfolder next to the camera originals. When the lead editor opens the main DaVinci Resolve application and imports the R3D files, Resolve instantly detects the adjacent proxy folder and attaches them automatically. The editor simply clicks "Prefer Proxies" and begins cutting immediately.

When should you skip local proxy generation entirely and use cloud-based ingestion?

You should skip local proxy generation when your production has access to Cutsio's enterprise raw ingestion add-on, which accepts native RED R3D and ARRI RAW files directly — the cloud handles the transcode, Visual Intelligence indexes every frame for search, and the original camera files remain attached for conform and finishing.

The Blackmagic Proxy Generator is effective, but it still requires the DIT to maintain a dedicated workstation running overnight, consumes local storage for proxy files, and adds an extra step before the director can review dailies. Cutsio eliminates these overheads entirely. The DIT uploads the native R3D or ARRI RAW files from the camera cards directly to Cutsio. No manual pre-transcode or separate ProRes proxy creation is required. Cutsio transcodes the raw files into streamable review assets on the backend, so the director can begin reviewing within minutes of the upload completing — not the next morning after the proxy render finishes.

The original RED R3D files are retained as attachments on each asset, available for download and conform when the project moves to finishing. Visual Intelligence indexes every frame of the review stream, making the footage searchable by visual content — particularly valuable for RED shoots where MOS footage has no scratch audio to search by.

| Step | Local Proxy Workflow | Cutsio Cloud Workflow |

| :--- | :--- | :--- |

| Card offload | DIT copies to RAID | DIT copies to RAID |

| Transcode | Proxy Generator runs overnight (2–8 hrs) | None on DIT workstation |

| Upload | ProRes proxies uploaded separately | Native R3D files uploaded directly |

| Review | Director reviews next morning | Director reviews minutes after upload |

| Original files | Managed on separate RAID storage | Attached to each asset in Cutsio |

| Visual Search | Not available | Frame-level search of every clip |

How do you present the first assembly of proxy footage to stakeholders?

Render the first assembly and upload it to Cutsio, providing a white-labeled, frictionless presentation layer where stakeholders can review the cut securely without worrying about proxy resolution. For productions using Cutsio's raw ingestion, the review stream is generated automatically from the native camera files — no separate render step needed.

Once the proxies are cut into a rough assembly, the director or agency needs to see the progress. Sending a rough cut via a generic Dropbox link looks unprofessional, especially since proxy footage is intentionally low-resolution. By uploading the assembly to Cutsio, you elevate the viewing experience. Cutsio provides a branded, password-protected environment with view tracking, frame-accurate commenting, and approval gates. The stakeholder experiences frictionless playback, and the team can use Cutsio's approval gates to get sign-off on the pacing before moving back to the high-resolution R3D files for color grading.

How does Visual Intelligence help you find specific shots across terabytes of R3D dailies?

Visual Intelligence indexes every frame of the uploaded review stream, allowing editors and directors to search R3D footage by visual content — finding specific compositions, actions, or objects without scrubbing through clips by filename.

When a RED shoot generates hundreds of R3D files named A001_C001_0426BC.r3d, finding a specific shot by memory alone is impractical. Visual Intelligence analyzes the visual content of every frame and makes it searchable. A director reviewing dailies can search for "wide shot of talent entering the warehouse" and get the exact clip and timestamp from across the entire shoot day. This is especially valuable for RED shoots where the high data volumes make manual logging impractical.

Agentic Chat extends this further. The post supervisor can ask "Show me all the close-ups from the car scene shot at 120 fps" and the system retrieves the matching clips by combining visual content with R3D header metadata like frame rate and compression ratio.

FAQ

Is the Blackmagic Proxy Generator free?

Yes, a basic version of the Proxy Generator is included with the free version of DaVinci Resolve, while the Studio version unlocks advanced hardware acceleration and H.265 encoding.

What is the best proxy format for Mac editors?

ProRes 422 Proxy at 1080p resolution is the absolute best format for Mac editors, as the M-series hardware media engines decode ProRes flawlessly with zero battery drain.

Can the Proxy Generator run on a separate computer?

Yes, many professional workflows install the Proxy Generator on a dedicated "ingest laptop" that runs 24/7, keeping the main editing workstations free for creative work.

How do I get RED R3D ingestion enabled on my Cutsio account?

RED R3D and ARRI RAW ingestion is available as an enterprise add-on for qualified production accounts. Contact the Cutsio sales team to enable raw format support for your production.

Does Cutsio replace the need for local proxies entirely?

For the review and selects phase, yes — Cutsio generates streamable review assets from native R3D files in the cloud. For the final conform in DaVinci Resolve, you will still work with the original R3D files from your local RAID.
