If your LED display is flickering on camera, the fastest fix is two steps: set your display brightness to 100% and match your camera's shutter speed to your local power frequency — 1/60s for 60Hz regions (US, Canada, Japan) or 1/50s for 50Hz regions (Europe, most of Asia). Most LED flicker on camera happens because the display uses PWM dimming at lower brightness levels, or your shutter speed is out of sync with the power grid frequency. Your display isn't broken — it's a settings mismatch you can fix in under a minute.
3 Quick Fixes to Stop LED Flicker on Camera
Before diving into the technical explanation, try these three steps in order. Each one tackles a different root cause, and for most streamers and content creators, step one alone eliminates the problem entirely.
1. Set Your LED Display Brightness to 100%
This is the single most effective fix. When an LED display is set below 100% brightness, it uses a technique called PWM (Pulse Width Modulation) to dim the LEDs — rapidly switching them on and off faster than your eye can detect. Your camera, however, captures individual frames and can catch those "off" moments. At 100% brightness, the LEDs stay continuously lit with no switching, so there's nothing for the camera to catch.
If you're using a Divoom pixel display like the Times Gate, Pixoo 64, or Ditoo-Pro, open the Divoom App, select your device, and drag the brightness slider all the way to the right. You can always lower it back down after you finish recording.
2. Match Your Shutter Speed to Your Power Frequency
LED light output has a subtle ripple that matches your local power grid frequency. If your camera shutter speed isn't a clean multiple of that frequency, each frame captures a slightly different amount of light — producing visible horizontal bands of light and dark across your footage.
Here's a quick reference table:
| Power Frequency | Regions | Safe Shutter Speeds |
|---|---|---|
| 60 Hz | US, Canada, Japan, Mexico | 1/60s, 1/120s, 1/240s |
| 50 Hz | Europe, UK, most of Asia, Australia | 1/50s, 1/100s, 1/200s |
If you shoot at the cinematic standard of 1/48s while in a 60Hz region, that's where most flicker appears. Switch to 1/60s and the bands disappear.
3. Use 30fps or 60fps Instead of 24fps or 120fps
Frame rate interacts with both the PWM frequency and the power ripple. At 120fps (slow motion), the camera is capturing frames so rapidly that it's far more likely to catch the LED switching cycle — which is why iPhone slow-motion footage shows aggressive flicker. At 24fps, the frame interval doesn't evenly divide into common LED refresh rates, creating a beat frequency that shows up as slow, rolling flicker.
Switching to 30fps or 60fps aligns the frame interval with both the power grid cycle and most LED refresh rates. If you must shoot at 120fps for slow motion, set your display brightness to 100% first — that removes the PWM component, leaving only the power ripple to deal with.
The video above walks through the same frame-rate and shutter-speed matching process with real footage examples, which makes it easier to see the difference each setting change makes on screen.
Why LED Displays Flicker on Camera
Understanding the root cause helps you troubleshoot faster when the quick fixes don't fully solve your situation. LED flicker on camera comes from three overlapping mechanisms, and identifying which one you're dealing with narrows down the solution.
PWM Dimming: The Most Common Cause
LEDs can only be fully on or fully off — there's no in-between. To create the appearance of lower brightness, LED controllers use Pulse Width Modulation: they switch the LED on and off hundreds or thousands of times per second. At 50% brightness, the LED spends half the time on and half off. Your brain fills in the gaps, so you perceive a steady dim glow. But a camera shooting at, say, 1/120s might land on an "off" cycle in some frames and an "on" cycle in others, producing visible flicker.
This is why setting brightness to 100% is so effective — at full brightness, the PWM controller stops switching entirely, and the LED glows continuously. No switching means no flicker, regardless of your camera settings.
Power Frequency Ripple
Even when an LED is at 100% brightness, the AC power from your wall outlet oscillates at 50 or 60 times per second. The LED driver circuit converts this to DC, but tiny residual ripples at 100Hz or 120Hz remain in the light output. This ripple is invisible to your eyes, but if your shutter speed doesn't divide evenly into the ripple frequency, each frame captures a slightly different brightness level — and you see horizontal bands crawling across the image.
This is the same reason old fluorescent tube lights flickered on camera. The fix is the same: match your shutter speed to the power frequency. 1/60s divides evenly into 120Hz ripples (two cycles per frame), so every frame gets exactly the same amount of light.
Frame Rate and the Beat Frequency Effect
When your camera's frame rate and the LED's internal refresh rate aren't evenly divisible, the difference between them creates a "beat frequency" — a slow, visible pulsing that looks like flicker even though the LED itself is running smoothly. For example, if an LED panel refreshes at 240Hz and your camera shoots at 30fps, the math works out cleanly. But at 24fps, there's a remainder that produces a slow visible pulse every few seconds.
This effect is amplified at high frame rates like 120fps or 240fps because the frame interval becomes shorter than the LED's refresh cycle, making it more likely that consecutive frames land on different phases of the LED's output.
Match Your Shutter Speed to Power Frequency: Step by Step
The 180-degree shutter rule says your shutter speed should be roughly double your frame rate for natural-looking motion blur. So at 30fps, you'd normally shoot at 1/60s — which happens to be the correct speed for 60Hz power. At 24fps, the 180-degree rule suggests 1/48s, but that doesn't divide evenly into 60Hz, which is why 24fps footage in a 60Hz region is especially prone to flicker.
Here's how to resolve the conflict:
- If you're in a 60Hz region: Shoot 30fps at 1/60s or 60fps at 1/120s. Both combinations satisfy the 180-degree rule and eliminate power ripple. If you need 24fps for cinematic feel, try 1/60s — you'll lose a bit of motion blur smoothness, but the flicker will be gone.
- If you're in a 50Hz region: Shoot 25fps at 1/50s or 50fps at 1/100s. These are the European equivalents of the 30/60fps standard and align perfectly with 50Hz power.
- If you're not sure which frequency your region uses: Check whether your wall outlets are 110-120V (likely 60Hz) or 220-240V (likely 50Hz). When in doubt, try both shutter speeds and watch your camera's live preview — the correct one will show a completely steady image.
For professional cameras and cinema bodies, look for anti-flicker settings like Sony's Variable Shutter or Canon's Flicker Detection, which automatically adjust the shutter timing to sync with the local power cycle.
Fix LED Flicker on iPhone vs Android
The reason related searches show "led light flicker on camera iphone" and "led light flicker on camera samsung" as separate queries is that iPhone and Android handle shutter speed differently, and the fix isn't the same for both platforms.
iPhone Settings to Stop LED Flicker
The iPhone's default Camera app doesn't let you manually set shutter speed, which makes it harder to match the power frequency. But there are two things you can do immediately:
- Turn off HDR Video: Go to Settings > Camera > Record Video and toggle HDR Video off. HDR video processing can amplify flicker because it combines multiple exposures, each of which may capture a different phase of the LED's cycle.
- Avoid Slow-Mo modes: The 120fps and 240fps slow-motion modes are the most prone to flicker because the high frame rate catches the LED switching cycle. Stick to the standard 30fps or 60fps modes.
- Use a manual camera app: Apps like Blackmagic Camera or Filmic Pro give you direct shutter speed control on iPhone, letting you dial in exactly 1/60s or 1/50s to match your power frequency.
Android Settings to Stop LED Flicker
Most Android phones offer a Pro or Manual mode in the built-in camera app, which makes this fix much simpler:
- Samsung: Open Camera > More > Pro. Tap the shutter speed icon (usually labeled "S") and set it to 1/60 for 60Hz regions or 1/50 for 50Hz regions. Some Samsung models also have an anti-flicker option under Camera settings.
- Google Pixel: Pixel cameras don't expose manual shutter speed in the default app, but some models include an anti-flicker setting. Check Settings > Camera > Advanced. Alternatively, use a third-party app like Open Camera, which offers full manual controls including shutter speed.
- Other Android brands: Look for a "Pro," "Expert," or "Manual" mode in your camera app. The shutter speed control is usually represented by an "S" icon. Set it to match your power frequency.
Set Your Divoom Display Brightness to 100% for Streaming
If you have a Divoom pixel art display in your streaming or recording setup, the brightness setting is your first line of defense against on-camera flicker. All three of the main Divoom displays — the Times Gate multi-screen dashboard, the Pixoo 64 pixel art canvas, and the Ditoo-Pro retro pixel speaker — use PWM dimming when set below 100% brightness.
Here's the practical workflow for streamers and content creators:
- Open the Divoom App on your phone and connect to your display.
- Select your device from the device list.
- Find the brightness slider (usually on the main device control screen).
- Drag the brightness to 100% before you start recording or go live.
- After your stream or recording session, adjust it back to your preferred level for everyday use.
At 100% brightness, the LEDs in your Divoom display stay continuously illuminated with no PWM switching, which means there's no flicker source for the camera to capture. This one step eliminates the most common cause of LED flicker before you even touch your camera settings.
For more detailed setup guidance, the Divoom product manual page has full instructions for each device, including brightness controls, display modes, and connectivity troubleshooting.

If you've set your display to 100% brightness, matched your shutter speed to your power frequency, and you're still seeing flicker, there are a few more things to check:
Check for Mixed Light Sources
If you have multiple LED lights or displays in your shot, each one may have a different PWM frequency or refresh rate. A Divoom pixel display at 100% brightness won't flicker, but a cheap desk lamp or ring light next to it might. Try turning off non-essential lights one at a time to identify which source is causing the remaining flicker.
Use a Camera with Variable Shutter or Anti-Flicker Mode
Professional cameras from Sony, Canon, and Panasonic include variable shutter or flicker detection features that fine-tune the shutter timing in sub-degree increments. If you shoot with a mirrorless or cinema camera, dig into your menu for "Flicker" or "Variable Shutter" settings — they can resolve flicker that a simple 1/60s can't.
Post-Production Deflicker
If you've already recorded footage with flicker, tools like DaVinci Resolve's Deflicker effect (in the Color page) or Premiere Pro's Flicker Removal plugin can smooth out brightness fluctuations. This is a last resort — it's always better to fix flicker at the source than to repair it in post.
Frequently Asked Questions
Do all LED lights flicker on camera?
Most LED lights and displays use PWM dimming at brightness levels below 100%, which can cause flicker on camera. However, some high-end LED panels use DC dimming (continuous current adjustment) instead of PWM, which doesn't flicker at any brightness. The vast majority of consumer LED displays, including Divoom pixel screens, use PWM — so the 100% brightness rule is the most reliable universal fix.
Why does LED flicker only show up on camera and not in person?
Your eyes have a visual persistence of about 1/60 of a second, which blends the rapid on-off cycles of PWM into a steady, dimmed image. A camera shutter, on the other hand, captures a single instant — and if that instant happens during an "off" cycle, the frame appears darker. The difference between what your eye sees and what the camera captures is the entire basis of LED flicker.
Can I fix LED flicker after recording?
Yes, but it's not ideal. DaVinci Resolve's Deflicker effect and Premiere Pro's Flicker Removal plugin can reduce visible flicker in post-production, but they work by averaging brightness across frames, which can soften detail and introduce motion artifacts. It's always faster and cleaner to fix the flicker at the source by adjusting brightness and shutter speed before you record.
Why does my iPhone show LED flicker but my camera doesn't?
Most iPhone models use a CMOS sensor with a rolling shutter, which scans the sensor row by row rather than capturing the entire frame at once. This makes rolling-shutter flicker (horizontal bands) more visible than on cameras with faster sensor readout or global shutters. Additionally, iPhone HDR video mode combines multiple exposures, which can amplify the effect. Turning off HDR video and using a manual camera app with shutter speed control usually resolves it.
LED display flicker on camera is a physics problem, not a product defect. Once you understand that PWM dimming and power frequency are the two main culprits, the fix is straightforward: set your display brightness to 100%, match your shutter speed to your local power frequency, and choose 30fps or 60fps over 24fps or 120fps. If you're using a Divoom display in your setup, that brightness slider in the Divoom App is your quickest win — drag it to 100% before you hit record, and the flicker should disappear before you even touch your camera settings.
