Proxies: The Secret to Editing 4K Video on a Weak Laptop (Without the Lag)

By the Arab Seed News Post-Production Team

There is nothing more frustrating than having a brilliant creative idea, sitting down to edit, and then watching your computer screen freeze for five seconds every time you press “Play.” We’ve all been there—trying to force a mid-range laptop to handle heavy 4K footage, only to end up wanting to throw the machine out the window.

At Arab Seed News, we often get asked: “Do I need to buy a $3,000 MacBook Pro to edit 4K?” Our answer is always a loud NO. The secret isn’t more RAM; the secret is a workflow hack that professional Hollywood editors have been using for decades: Proxies.

What Exactly is a Proxy? (The “Stunt Double” Concept)

Think of a Proxy as a “stunt double” for your high-quality video. When you shoot a video in 4K, the file is massive and complex, making your CPU work overtime just to show you a single frame.

A Proxy is a low-resolution, lightweight copy of that same file. During the edit, your software (Premiere, Resolve, or even CapCut) uses this “stunt double” to keep the playback buttery smooth. When you finally hit “Export,” the software automatically swaps the low-quality proxy back for the original 4K masterpiece. You get the speed of a 720p edit with the quality of a 4K finish.

Why “Small Files” are Better than “More RAM”

Even in 2026, many creators think adding an extra 16GB of RAM will solve their stuttering timeline. But the bottleneck is often the Read Speed of your hard drive and the Decoding Power of your processor. By creating Proxies (usually in a format like ProRes 422 Proxy or H.264 Low Res), you are essentially giving your computer a “vacation.” You can apply cuts, transitions, and even basic color grading without hearing your laptop fans sound like a jet engine.

How We Use Proxies at Arab Seed News

If you want to try this today, here is the professional workflow we recommend:

  1. Import your 4K footage into your editor.

  2. Right-click the files and look for “Create Proxies.”

  3. Choose a low resolution (we usually use 1280×720).

  4. The “Magic” Toggle: Make sure you find the “Toggle Proxies” button in your preview window. When it’s blue (on), you are editing the fast files. When you turn it off, you see the crisp 4K original.

The Verdict: Is it Worth the Extra Step?

Creating proxies takes a few minutes at the start of your project, and yes, it uses a little bit of extra disk space. But compared to the hours of frustration caused by a lagging timeline, it’s a tiny price to pay.

Our Advice: If your computer isn’t a “beast,” stop fighting with your hardware. Use Proxies. It’s the difference between hating the editing process and actually enjoying the craft of storytelling. In 2026, being a “pro” isn’t about having the best gear; it’s about knowing the smartest shortcuts.
