I thought i broke my camera in less than a day!! Thanks to you!!!

In the U.S. the power grid is 60 Hz (On/Off 60 times per second)

1/60 shutter speed fixes this problem or if your camera has variable shutter you can run 1/60 and/or 1/119.9 and it gets rid of the banding. Think in multiples of 60. 🤙🏻

We recently shot some videos for a client inside of a car painting booth with fluorescent bulbs EVERYWHERE. Not only do they flicker like mad but, they cast a green hue. We fixed all the problems by punching two Amaran 200D at the ceiling to get some clean light in there and then ran both Sony FX cameras at shutter 1/60. The camera filming in 59.94 fps we ran it at 1/119.9 shutter speed and that worked great.

Also, in Davinci Resolve there is a tool in the effects panel which De flickers footage if you ever have flickering footage.

Happy shooting!
🤙🏻😎

Thank you for getting right to the point and not over-explaining like so many other tuts do. My problem is solved!

[PaigeArmstrong]

I'm new to photography and video and I was worried that my camera wasn't working properly.. this resolved my issue perfectly.. lighting is so important. Thank you Jordan.

[yarospringglory]

great explanation- just happened to me and i was shocked to that 1/50 it was giving me this. Thanks so much

[JonelKingas]

omg i thought my phone camera was broken, but it was just my night lamp wtf, first setting everything is fine but second setting that is less bright of the lamp this started happening on my phone camera rapidly

[ShawnSwander]

I'm a photographer but I used to be a nuclear engineer and work on power plants so we were trained in electrical systems. So I have an interesting blend of knowledge on how electronics interact with shutter speed.

If the lights flicker at 1/60 Hz and you shoot 1/50 SS you'll get banding because each scan of your sensor scans a full cycle of the lights plus another 20% of your sensor will scan a second light cycle creating a band by about 1 stop brighter (if that's the only light) that is as big as 20% of your screen. The more lights that are in sync with your camera the less pronounced the band will be. Most likely the circuitry wasn't made for US electrical systems that operate at 60Hz. If you're in Europe 50Hz is more common but really bad circuitry has variable frequencies and it may be that no shutter speed syncs with it perfectly.

So there are times when 1/60 or 1/120 will give you less banding than 1/50. If the lights cycle at 60Hz. So you might consider using 30fps because it gives you the 180 degree rule and syncs better with US electronics. Another way is you could use a global shutter or 1/30 shutter speed.

[bobwoolcock]

Yeah - it's a weird concept if the shutter speed is longer than the frame rate. I think for many types of shooting - in particular live music videos in low light, 24fps and 1/25th shutter speed works well. With two mirrorless cameras I like to select an aperture that is the widest on the slowest lens and use it on both cameras. So f6.3, 24fps, 1/25th second - then, in manual mode, simply find the ISO results in the exposure you want as you view it through the electronic viewfinder.

[victorfox]

I think you need to go up to 1/60 and shoot at 30fps. It has to do with AC electricity.

[ags]

Apparently it’s caused by the rolling shutter in the camera as it updates the image of each frame from top to bottom. That’s why you get a jello effect when you pan quickly from left to right. Cameras which use a global shutter do not have this side-effect.

[ArtandLes]

Great vid.. You explained it very clearly compared to others videos i've watched. Thank you. Support ❤️

[uselesstv]

some science behind it.. that may help you

Alternating Current or your AC, , is a big thing to take into account. Alternating current (anythign that plugs into the wall) i
America is 60hz, in the UK its 50hz, .

Battery powered lighting, which runs off Direct Current DC, doesnt alternate as its continuous direct light source. so this is why you wont get the bars when using certain lights you bring with you.

you want your hz of your camera to match the AC of whever light source you are using. you do this by changing the hz mode. from PAL TO NTSC or vice versa.

Camera HZ
PAL = 50hz
NTSC = 60hz

UK AC = 50hz
America AC = 60 hz

So if in america, try NTSC (60hz) with a shutter speed that multiples by 60, aswell as a the frame rate. eg, Shutter speed, 30/60/120 etc

if anywhere else like EUROPE or UK, Set to Pal (50hz) and also set shutter speed and frame rate to a multiple of 50. eg. 25/50/100 etc

Thanks. It happened to me at 125 speed. Wish I had access to this video when it was actually happening during my event.

[CrimsonLolita_]

My guy immediately knew why we clicked on this video 🙌🙌🙌

[MinuteMon]

Thank you!! This was so helpful, you deserve more subs!!!

[braxtonslife]

Thank you for this video. I was pretty damn scared, because I am starting to learn how to use cameras properly, and I hadn't had these issues until recently. Thought I broke the camera

[TheRealRappingRealtor]

What if your trying to make sure you can slow footage down and have to stay at a higher Shutter speed?

[magdelenatrevera]

I have led light in my room and they are doing the same thing. Do you know how I can fix it on my phone ?

[youritguy]

You have solved my issue big time. Thank you thank you

[ClaudiaGoodwin]

Love this! I have my very first wedding this November and I am SO nervous but SO excited. Just bought myself a Canon 5D Mark IV and a 24-70, but Ive heard I should definitely rent another camera... any tips on a first wedding would be amazing! (shots to look out for, gear, communication, what to bring, anything at all!!)
