You’ve seen the clips. A grainy, vibrating black circle surrounded by a weird, flickering white halo that looks more like a smudge on a dirty lens than a celestial event. It’s frustrating. People wait decades for a total solar eclipse, haul thousands of dollars of camera gear into a random cornfield in Indiana or a dusty plain in Mexico, and still end up with a solar eclipse in video that looks, frankly, terrible. It’s not just a skill issue. It’s a physics problem.
Recording a solar eclipse isn't like filming a sunset. When the moon slides in front of the sun, you aren't just dealing with "less light." You are dealing with dynamic range shifts so violent they can literally melt the sensor inside your iPhone or mirrorless camera if you aren't careful. I’ve seen sensors with permanent "burn-in" marks because someone thought a pair of sunglasses over the lens was "good enough." It wasn't.
The Equipment Trap: Why Your Smartphone Isn't Enough
Most people reach for their pocket the moment the sky starts to dim. It’s instinct. But a standard smartphone camera is designed to see like a human eye—mostly. When you try to capture a solar eclipse in video using a wide-angle mobile lens, the sun occupies maybe 5% of the frame. The phone's software gets confused. It tries to expose for the dark sky, which blows out the solar corona into a featureless white blob.
You need glass. Specifically, you need a telephoto lens with a focal length of at least 400mm to 600mm if you want the sun to actually fill the frame. But even then, you can't just point and shoot.
NASA and professional astrophotographers like Terry Virts have long preached the "Filter First" rule. During the partial phases—the hour or so leading up to totality—you must use a certified ISO 12312-2 solar filter. If you don't, the concentrated sunlight acts like a magnifying glass hitting an ant. Your camera sensor is the ant. The only time that filter comes off is during the two to four minutes of totality. If you miss that window by even a few seconds, you risk frying your gear or, worse, ruining the footage with massive internal reflections known as "lens flare."
The "Diamond Ring" and the Frame Rate Secret
There is a specific moment that everyone wants to catch: the Diamond Ring effect. It’s that final flash of sunlight peeking through a lunar valley just before the world goes dark.

If you're filming at 24 frames per second (fps), you’re going to miss the nuance. The light changes too fast. Professionals usually switch their solar eclipse in video settings to at least 60 fps or even 120 fps for this specific transition. It allows you to slow down the footage in post-production, turning a half-second flash into a three-second cinematic reveal.
Why Auto-Focus is Your Enemy
Seriously. Turn it off.
As the moon covers the sun, the contrast levels drop. Your camera’s autofocus system will start "hunting." It’ll move the lens back and forth, trying to find a sharp edge to lock onto, and usually, it’ll fail right when the Baily's Beads appear. Set your focus to infinity manually during the partial phase and then tape your focus ring down with gaffer tape. Don't touch it.
Real-World Blunders: What We Learned from 2017 and 2024
The 2017 Great American Eclipse was a masterclass in what not to do. Thousands of hours of solar eclipse in video were uploaded to YouTube, and roughly 80% of them suffered from "The Shake." Because the sun is so high in the sky, tripods are often extended to their maximum height, making them incredibly unstable. Even a light breeze makes the sun dance around the frame like a caffeinated firefly.

- Weight your tripod down with a sandbag or your camera bag.
- Use a remote shutter release. Touching the "Record" button creates a vibration that lasts for 3 seconds.
- Check your storage. I know a guy who spent three hours setting up a RED cinema camera only to have the SSD fill up thirty seconds before totality. He missed the whole thing because he was staring at a "Media Full" error message.
The 2024 eclipse showed us the rise of "HDR" processing in video. Some creators used multiple cameras to "bracket" the exposure. One camera was set to capture the dim outer corona, while another focused on the bright solar prominences (those pinkish loops of plasma). By layering these in software like Adobe Premiere or DaVinci Resolve, they created videos that actually looked like what the human eye sees—something a single sensor simply cannot do on its own yet.
Don't Forget the Environment
Honestly, sometimes the best solar eclipse in video isn't of the sun at all. It's the ground. During the partial phases, look at the shadows under a leafy tree. The tiny gaps between leaves act as pinhole projectors, casting thousands of little crescent suns onto the pavement. It’s eerie. It looks like a glitch in the Matrix.
Also, watch the horizon. During totality, you get a 360-degree sunset. The colors are bizarre—deep purples and bruised oranges in every direction. If you have a second camera, like a GoPro, set it up on a wide angle just to capture the reaction of the crowd and the change in light. The sound is just as important. The way the birds stop chirping and the crickets start up is a sensory experience that a close-up of a black circle just doesn't convey.

Technical Checklist for your Next Opportunity
You don't want to be fumbling with menus when the sun disappears. The temperature drops about 10 degrees in minutes. Your hands might get shaky. The "shadow bands"—weird, wavy lines of light—might start racing across the ground. It’s overwhelming.
- Manual Mode Everything: Lock your ISO (usually 100 or 200), lock your shutter speed, and lock your white balance to "Daylight." If you leave white balance on "Auto," the camera will try to "fix" the eerie blue-ish light of totality and turn it into something boring and neutral.
- Resolution Matters: Shoot in 4K or 8K if you can. This allows you to crop in later during editing without losing detail. Even if you have a 600mm lens, the sun might still look small; that extra resolution is your safety net.
- The Battery Factor: Cold air drains batteries. Since the eclipse usually causes a localized temperature drop, make sure your batteries are at 100% and maybe even tape a small hand warmer to the battery compartment if you're in a chilly climate.
The Post-Processing Reality
Once you have your solar eclipse in video on your computer, don't just dump it on TikTok. The "Raw" footage will look flat. You’ll need to boost the contrast and play with the highlights to make the corona pop. Use a "S-Curve" in your color grading software. This mimics the way our eyes perceive the massive difference between the black moon and the glowing atmosphere of the sun.
Be careful with saturation. Some people crank the blues and purples to make it look "spacey," but it ends up looking fake. The real corona is a pearly, ghostly white. It has a texture like silk. If you over-process it, you lose those fine magnetic field lines that are the hallmark of a great capture.
Actionable Steps for Capturing the Sun
If you’re planning to film the next big celestial event, start practicing today. You don't need an eclipse to practice filming the sun (with a filter!).
- Buy a Solar Filter Now: Don't wait until the week before. Prices triple and "fakes" flood the market. Look for brands like Thousand Oaks Optical or Baader Planetarium.
- Test Your Longest Lens: Go outside and try to keep a stationary object in the center of your frame at 400mm+ without it shaking. You’ll realize quickly that your tripod might be the weakest link in your chain.
- Practice "The Filter Pull": Set a timer for 2 minutes. Practice safely removing the solar filter from the front of your lens without moving the camera, and then putting it back on. You have to be able to do this in the dark, by feel, because when totality hits, you won't want to take your eyes off the sky to look at your lens.
- Download an Eclipse App: Use something like Solar Eclipse Timer by Gordon Telepun. It provides audible cues so you know exactly when to take the filter off and when to put it back on, down to the second, based on your GPS coordinates.
The most important thing? Remember to look up with your own eyes for at least thirty seconds. No solar eclipse in video, no matter how high the bitrate or how expensive the lens, can replicate the feeling of the sun’s warmth vanishing and seeing the crown of the stars in the middle of the afternoon. Use the tech, but don't let it become a barrier between you and the universe.
