That weird warped effect in your videos? When straight buildings lean and fast-moving objects look like they’re made of jello? That’s rolling shutter distortion, and it’s ruined countless shots for photographers and videographers.
Rolling shutter is a method of image capture where the camera sensor records the scene line by line instead of all at once, causing distortion in fast-moving objects or during camera movement.
Most digital cameras today use CMOS sensors with rolling shutters. Understanding this effect isn’t just technical knowledge—it’s essential for anyone serious about video quality. After working with everything from iPhone footage to professional cinema cameras, I’ve seen how rolling shutter can make or break a shot.
This guide will show you exactly what rolling shutter is, why it happens, and most importantly, how to prevent and fix it in your work.
Understanding Rolling Shutter Definition and Core Concepts For 2025
Rolling shutter describes how most modern digital cameras capture images. Instead of exposing the entire sensor at once (like a global shutter), these cameras scan the sensor sequentially, typically from top to bottom.
Rolling Shutter: A camera technology that captures images by scanning across the sensor line by line, with each row recorded at a slightly different moment in time.
This scanning process happens incredibly fast—usually in just a few milliseconds. But that tiny delay between the top and bottom of your frame is enough to cause noticeable distortion when things move quickly.
Most cameras using CMOS sensors have rolling shutters. This includes smartphones, DSLRs, mirrorless cameras, and even many professional video cameras. The alternative, global shutter, captures the entire frame simultaneously but comes with its own trade-offs in cost and image quality.
The key thing to remember: rolling shutter isn’t a flaw—it’s a design choice that enables smaller, cheaper, and better-performing cameras in many ways. But understanding its limitations is crucial for getting the best results.
How Rolling Shutter Works The Technical Details?
Let’s break down what’s actually happening inside your camera. When you press the shutter button, your camera’s sensor doesn’t capture everything at once. Instead, it activates each row of pixels sequentially.
Imagine reading a book from top to bottom, but instead of words, you’re capturing light. Your camera’s sensor reads out data in much the same way—row 1, then row 2, then row 3, and so on until it reaches the bottom. This entire process typically takes between 5 and 20 milliseconds, depending on your camera.
Here’s why timing matters: if nothing moves during those few milliseconds, you’ll never notice the difference. But if you’re panning quickly, or if your subject is moving fast, each row captures a slightly different moment in time.
The result? Distortion. Vertical lines become diagonal. Fast-moving objects appear stretched or compressed. Rotating propellers look like bizarre curves instead of straight blades.
Professional cinematographers measure rolling shutter using a percentage. A camera with 10% rolling shutter means there’s a 10% time difference between capturing the top and bottom of the frame at 1/1000s shutter speed. Lower is better—high-end cinema cameras might have under 5%, while some smartphones can exceed 20%.
Common Rolling Shutter Effects and Examples
You’ve probably seen rolling shutter effects without realizing what they were. Here are the most common types:
The Jello Effect
This is what most people think of when they hear “rolling shutter.” When you move the camera quickly, especially side to side, the entire image appears to wobble like jello. Buildings lean, vertical lines curve, and the whole frame feels unstable. It’s most noticeable when shooting handheld while walking or during rapid pans.
Propeller and Fan Distortion
Classic example: helicopter propellers or ceiling fans that look like weird curves or multiple blades instead of straight lines. Because each blade moves significantly between the time the camera captures the top and bottom of the frame, the rotation gets distorted into artistic but unrealistic shapes.
Skewed Vertical Lines
When panning horizontally past vertical objects (like buildings or poles), they appear to lean in the direction of your pan. The faster you pan, the more pronounced the lean. This happens because the base of the building is captured later than the top, after the camera has already moved.
Flash Banding
If someone takes a photo with flash while you’re recording video, you’ll see a bright horizontal band or partial exposure in your footage. This happens because the flash illuminates only part of the sensor during its sequential readout.
Auto Exposure Issues
Sometimes you’ll see horizontal bands of different brightness when shooting under flickering lights or during rapid exposure changes. Each row of the sensor might capture slightly different lighting conditions as the camera adjusts.
Why Rolling Shutter Matters Problems and Impact In 2025?
For casual shooters, mild rolling shutter might not be a dealbreaker. But for professional work, it can be a serious problem.
Professional videographers spend thousands of dollars on cameras specifically to minimize rolling shutter. When you’re shooting a documentary, wedding, or commercial, that jello effect can make your footage look amateurish—or even unusable.
Sports photography becomes particularly challenging. Fast athletes, racing cars, or any quick movement can appear distorted. I once shot an entire soccer match only to find that fast kicks looked unnaturally elongated, ruining otherwise great action shots.
Architectural photography suffers too. Perfectly straight buildings appear curved and distorted when you pan or tilt the camera. This is especially problematic for real estate photography where accuracy matters.
Even smartphone users struggle. While phones have gotten better, they still exhibit noticeable rolling shutter during normal activities like walking while recording. Ever wonder why your vacation videos look wobbly? Rolling shutter is often the culprit.
The financial impact is real too. Fixing rolling shutter in post-production takes time and sometimes requires expensive software. Prevention might mean buying more expensive equipment or sacrificing other camera features. For professionals working on tight budgets, these tradeoffs matter.
How to Prevent Rolling Shutter Proven Techniques In 2025?
The best way to handle rolling shutter is to prevent it in the first place. Here are techniques I’ve learned over years of shooting:
Adjust Your Shutter Speed
Faster shutter speeds reduce rolling shutter effects by minimizing the time each row is exposed. While this doesn’t change the sensor readout speed, it reduces motion blur, making the distortion less apparent. For video, follow the 180-degree rule but don’t be afraid to go faster if you’re seeing rolling shutter issues.
Control Your Movement
Smooth, deliberate camera movements are your best defense. Avoid rapid pans, quick tilts, or jerky handheld movements. Use a gimbal or stabilizer when possible. When shooting handheld, keep your movements slow and deliberate.
Change Your Angle
Sometimes a simple angle change makes a huge difference. If you’re getting vertical line distortion, try positioning yourself so you don’t need to pan past vertical objects. For moving subjects, anticipate movement and position yourself where the motion will be less problematic.
Use Mechanical Shutter (When Available)
Many cameras offer a mechanical shutter option for still photography. Unlike the electronic rolling shutter, a mechanical shutter uses physical curtains that expose the entire sensor at once, eliminating rolling shutter distortion. Note: this only works for still photos, not video.
Choose Your Shots Wisely
Understanding when rolling shutter will be problematic helps you avoid those situations. Avoid shooting fast-moving subjects from the side, don’t pan quickly past vertical lines, and be extra careful with rotating objects in frame.
Use Electronic Shutter Modes
Some cameras offer different electronic shutter modes. Check if your camera has a “silent shooting” mode or other electronic shutter options—some have better rolling shutter performance than others.
Fixing Rolling Shutter in Post-Production
Sometimes, despite your best efforts, you’ll end up with rolling shutter distortion in your footage. The good news? Modern software can help—though with limitations.
Adobe Premiere Pro
Premiere Pro includes a “Rolling Shutter Repair” effect under the Distort menu. It’s straightforward: adjust the “Scan Direction” (usually top to bottom) and increase the “Correction Amount” until the distortion improves. Start low—around 25-30%—and gradually increase. Too much correction can create its own artifacts.
Final Cut Pro
Apple’s solution is called “Rolling Shutter” and works similarly. It’s found in the Effects browser under Distort. The interface is simpler with just a single slider, but the results are comparable to Premiere Pro.
DaVinci Resolve
Resolve offers rolling shutter correction in the Studio version. It’s located in the Color page under the “Motion Effects” panel. DaVinci’s implementation is particularly good at preserving image quality during correction.
Specialized Software
Tools like ProDAD’s Defishr or RE:Vision Effects’ RSMB (Real Smart Motion Blur) offer more advanced rolling shutter correction. These cost extra but can handle severe cases better than built-in tools.
⏰ Time Saver: Fix rolling shutter early in your editing workflow. Applying color correction or effects before fixing rolling shutter can make the correction less effective.
Remember: post-production fixes are compromises. You’re essentially warping the image to counteract the distortion, which can reduce sharpness or create new artifacts. Prevention is always better than correction.
Choosing Cameras: Rolling Shutter Performance Guide (2025)
When camera shopping, rolling shutter performance should be on your checklist, especially if you shoot video regularly.
Global shutter cameras are the gold standard—no rolling shutter at all. But they’re rare and expensive, mostly found in high-end cinema cameras like the RED Komodo or Sony Venice. These cameras typically cost $10,000 and up.
For the rest of us, look for cameras with fast sensor readout speeds. Mirrorless cameras generally perform better than DSLRs, and newer models typically have better rolling shutter performance than older ones.
Sony’s Alpha series has improved significantly—the A7S III and A7 IV have much better rolling shutter than earlier models. Canon’s R5 and R6 perform well too. Blackmagic’s Pocket Cinema cameras offer good performance for their price point.
Smartphones vary widely. Recent iPhones handle rolling shutter better than many Android phones, thanks to computational photography tricks. But all phones still struggle with severe rolling shutter during movement.
When comparing cameras, look for rolling shutter tests online. Many reviewers measure this specifically, showing you exactly how different cameras perform under identical conditions. Pay attention to the percentage numbers—under 10% is good, under 5% is excellent.
Looking ahead, sensor technology continues to improve. Stacked CMOS sensors, like those in Sony’s latest cameras, are dramatically reducing rolling shutter. Within a few years, rolling shutter might be a non-issue even in consumer cameras.
Frequently Asked Questions
What is the rolling shutter?
Rolling shutter is a camera technology that captures images by scanning across the sensor line by line instead of exposing the entire sensor at once. This sequential capture can cause distortion when subjects or camera move quickly during the brief moment it takes to scan the entire frame.
What does “fix rolling shutter” mean?
Fixing rolling shutter means correcting the distortion caused by the sensor’s sequential capture method. This can be done by adjusting camera techniques to prevent distortion, or using post-production software to digitally correct warped footage. Software solutions essentially warp the image back to its proper shape, though they can’t always perfectly restore the original image.
What are the disadvantages of rolling shutters?
The main disadvantages include image distortion during fast movement, skewed vertical lines when panning, the “jello effect” during camera shake, and weird shapes with rotating objects like propellers. Rolling shutter can make professional footage look amateurish and limits shooting options for sports, action, and documentary work.
Why do Germans use rolladen?
That’s a different type of shutter! “Rolladen” refers to German rolling window shutters used for privacy, security, and energy efficiency in buildings. They have nothing to do with camera rolling shutter effects—the similarity in names is just a coincidence.
What shutter speed eliminates rolling shutter?
No shutter speed completely eliminates rolling shutter since it’s caused by sensor readout speed, not exposure time. However, faster shutter speeds (1/500s or faster) can reduce the visible effects by minimizing motion blur. The real solution is using cameras with faster sensor readout or global shutters.
Can rolling shutter be completely fixed in post?
Unfortunately, no. Post-production correction can improve rolling shutter distortion but often introduces its own artifacts or reduces image sharpness. Software fixes are best for mild to moderate cases—severe rolling shutter may be impossible to fully correct without noticeable quality loss.
Final Thoughts
Rolling shutter is one of those technical challenges that every photographer and videographer eventually encounters. It’s frustrating, yes, but understanding how it works gives you the power to prevent it or minimize its impact.
Over my years shooting everything from weddings to wildlife documentaries, I’ve learned that working with rolling shutter is about compromise and technique. The best results come from combining smart shooting practices with the right equipment choices.
Remember: rolling shutter doesn’t have to ruin your shots. With the knowledge from this guide, you can identify potential issues before they happen, adjust your technique accordingly, and know when post-production correction might help. Practice these techniques, and soon you’ll be capturing clean, distortion-free footage even in challenging situations.
Technology is improving too. Stacked sensors and better processing are reducing rolling shutter in newer cameras. Who knows? In a few years, rolling shutter might be as rare as film grain is today. Until then, master these techniques, and your work will stand out for all the right reasons.
