Editing Workflow Tip

Proxy Editing

Proxy editing is a video production technique that replaces high-resolution footage with lightweight stand-in files during the editing process, dramatically speeding up playback and rendering on less powerful machines.

Definition

Proxy editing is a workflow strategy used in video post-production where a low-resolution, lower-bitrate copy of your original footage — called a proxy file or video proxy — is used in place of the full-resolution source during the editing process. This stand-in file is much smaller and easier for a computer to process, enabling smooth real-time playback and faster editing even on hardware that would struggle with demanding formats like 4K RAW or ProRes. Once editing is complete, the project is 'relinked' to the original high-resolution files for final export, ensuring the finished output retains full quality. Proxy files are typically generated either in-camera, using NLE software (such as Final Cut Pro, DaVinci Resolve, or Adobe Premiere Pro), or through dedicated transcoding tools. Common proxy formats include H.264, DNxHD, and ProRes Proxy. For creators producing large volumes of long-form content — such as podcasters, YouTubers, or event videographers — proxy editing is essential for maintaining an efficient workflow before sending footage to an AI repurposing platform like OpenClip, which then automatically extracts viral moments and generates short-form clips.

Features

Faster Editing Performance

Low-resolution proxy files reduce the processing load on your CPU and GPU, enabling smooth real-time playback of footage that would otherwise stutter or lag.

Full-Quality Final Output

At export time, your project relinks to the original high-resolution source files automatically, so your finished video retains maximum quality despite the lightweight editing experience.

Reduced Storage Demands

Proxy files are a fraction of the size of their originals, making it easier to store and manage large video projects without filling up fast NVMe drives or shared storage.

Format Flexibility

Proxies can be generated in a variety of codec formats — including H.264, ProRes Proxy, and DNxHD — so editors can choose the best balance of compatibility and performance for their system.

Remote & Collaborative Workflows

Sharing lightweight proxy files across teams or remote editors is far more practical than transferring multi-gigabyte RAW files, enabling distributed production pipelines.

Streamlined Repurposing Pipeline

Efficiently edited and organized long-form footage moves smoothly into AI repurposing tools like OpenClip, which can then detect viral clips and generate short-form content at scale.

Frequently Asked Questions

Proxy editing is a technique where lower-resolution, smaller-file-size copies of your original footage (called proxies) are used during the editing process. This makes editing smoother and faster. When you're ready to export, the editing software swaps the proxies back out for the original high-quality files so the final output is full resolution.

A proxy file is a lower-resolution, lower-bitrate stand-in created from your original footage. It contains the same content but is much smaller in file size and easier to process. The original file remains untouched and is used only for the final export. Proxies are not meant to be delivered — they're purely an editing convenience.

You should use proxy editing when working with high-resolution formats (4K, 6K, or RAW footage) on a machine that struggles to play them back smoothly, when using compressed but computationally heavy codecs, or when collaborating remotely where transferring large files is impractical. It's especially useful for long-form content creators who film hours of footage before repurposing it.

OpenClip processes your uploaded video files directly using AI — it doesn't require you to create proxies beforehand. However, if your editing software generates a proxy-based offline edit, you should always export or upload the final full-resolution version to OpenClip so the AI viral clip detection, speaker tracking, and caption generation work with the best possible source material.

Most professional and prosumer NLEs support proxy editing, including Adobe Premiere Pro (via Proxy Workflow), Final Cut Pro (Proxy Media), DaVinci Resolve (Optimized Media and Proxy), and Avid Media Composer (Offline/Online workflows). Many cameras also offer in-camera proxy recording alongside full-resolution capture.

Common proxy formats include H.264 (widely compatible and small file size), Apple ProRes Proxy (low data rate but high editing performance on Mac), and Avid DNxHD/DNxHR (cross-platform professional proxy codec). The right choice depends on your editing software and hardware.

No — proxy editing does not affect the quality of your final exported video. The proxies are only used during the edit. Before export, your NLE relinks to the original high-resolution source files, so the delivered output is at full quality regardless of what resolution proxy you used during editing.

Edit Less, Create More — Let OpenClip Handle the Repurposing

Upload your long-form videos to OpenClip and let AI automatically detect viral moments, track speakers, and generate short-form clips — no manual editing required.
