Image Sequence Conform in DaVinci Resolve: The Ultimate VFX Handoff for Nuke Pipelines
Learn the exact workflow for exporting and conforming EXR image sequences between DaVinci Resolve and Nuke for high-end VFX feature film pipelines.
How do you conform an EXR image sequence in DaVinci Resolve for a Nuke VFX handoff?
To conform an EXR sequence for Nuke, go to the Deliver page in DaVinci Resolve, select the "EXR" format under the Custom export preset, set the codec to RGB half-float (PIZ compression), and ensure "Render at source resolution" is checked.
In feature film pipelines, video files like ProRes or MP4 are never used for VFX handoffs. Instead, pipelines use Image Sequences—specifically OpenEXR. An EXR sequence exports every single frame of a video clip as an individual, high-dynamic-range image file. This format holds massive amounts of color data (linear floating-point data), ensuring that when a VFX artist in Foundry Nuke keys out a green screen or tracks a 3D object, they have the maximum mathematical data available. When exporting from Resolve, you must ensure the frame numbering matches the source timecode perfectly so the VFX artist can track the shot back into the edit seamlessly.
How do you bring a rendered Nuke image sequence back into the DaVinci Resolve timeline?
To bring a Nuke sequence back into Resolve, open the Media Storage browser, click the three-dot menu to ensure "Frame Display Mode" is set to "Sequence," drag the folder into the Media Pool, and drop it over the original clip on the timeline.
When the VFX artist finishes the shot in Nuke, they will render out a new EXR sequence. If your DaVinci Resolve Media Pool is set to display individual files, importing this folder will crash your system with thousands of single images. By ensuring DaVinci Resolve treats the folder as a "Sequence," it collapses the 240 images into a single, playable video clip in the Media Pool. You then place this new VFX clip onto a higher video track (V2) directly above the original raw footage, ensuring the colorist can grade the final composite.
How should post-production supervisors present VFX shots for director approval?
Post-production supervisors should export the conformed VFX timeline and upload it to Cutsio, providing a white-labeled, secure environment where the director can approve the shots frame-by-frame.
VFX pipelines are expensive. Getting a director to approve a Nuke composite requires a flawless presentation layer. Sending an EXR sequence via a hard drive or a compressed Google Drive MP4 is unacceptable. Cutsio solves this by acting as a dedicated review platform. The supervisor uploads a high-fidelity render to Cutsio. The director receives a secure, branded link with frictionless playback. Using Cutsio's explicit approval gates, the director can sign off on the VFX shot, locking it in for the final color grade.
FAQ
What is the advantage of EXR over TIFF for image sequences?
EXR supports 16-bit and 32-bit floating-point color depth, which retains extreme highlight and shadow data beyond standard monitor limits, making it the industry standard for VFX compositing over TIFF.
Why is my EXR sequence playing back slowly in DaVinci Resolve?
EXR files are massive uncompressed data files. Unless you are running off a high-speed RAID array or NVMe SSD, the drive cannot feed the data to DaVinci Resolve fast enough for real-time playback.
What is PIZ compression in EXR exports?
PIZ is a lossless compression algorithm designed specifically for EXR files. It significantly reduces the file size on the hard drive without discarding any mathematical color data.
