Topic: How do I avoid Light flicker in my brick films?

Hey everybody! I have a huge question! (Not really) How can I avoid light flicker when I brick film? It just never goes away! I'm tired of it! My parents won't let me put paper on my lamps because it could catch fire. Please help!:( mini/madhead

This is not a chat room.  You should give people some time to reply.  KTproductions121, you got to use more insults if you want to be unhelpful and an !@#$ in your post.  You want to be a !@#$, got to do it right mini/tongue.

You don't need to put papers on your lamp unless you're trying to diffuse the intensity.  We can't answer your question without some more detail.  What's your arrangement?  What lamps and bulbs are you using?  Are you filming in a windowless room where you have full control of the lighting (no sunlight)?  What camera are you using?  Does it have full manual control options?  Are you wearing black?  Does your hand affect the set's lighting whenever it's next to the camera?  etc.

Re: How do I avoid Light flicker in my brick films?

I normally use two lamps. One on each side. I use a Canon ZR200 that has manual focus. There is one window in my room that I animate in, but I close the shades all the way. I use one 40 watt bulb on one side, and the other I use a 60 Watt bulb. I normally wear black too. I'll tell you this. Before the action starts, I take like 13-15 pictures, there is no flicker in that round of pictures, but when I put my hand into the picture and start animating, FLICKER! I've tried changing the camera settings, but nothing really works! Does that help?

Film at night.
Wear black.
When taking a frame, make sure to sit back in the same place every time.


Other than that it sounds like you havent set all your settings to manual, so when you put your hand in the frame, the camera changes slightly to adjust to your hand being there. Anywhere it says AUTO, turn it off. If you cant turn it off, then you're using the wrong camera.

Re: How do I avoid Light flicker in my brick films?

Thanks! Actually, I do animate at night.

Re: How do I avoid Light flicker in my brick films?

And all light sources are covered up? Even little ones such as lights on your monitor/computer that flicker..

Re: How do I avoid Light flicker in my brick films?

I don't animate using a computer. (yet)

Re: How do I avoid Light flicker in my brick films?

Any other tips on preventing light flicker?

Re: How do I avoid Light flicker in my brick films?

How long do you leave between pulling your hand out of the frame and taking the picture?

Re: How do I avoid Light flicker in my brick films?

I usually take the picture like 3-5 seconds after I take the frame. What's your suggestion?

Yeah, wait at least 5 seconds.

By the way, it would be nice if you could show us a short clip so we can see the flicker. There's different "types" of flicker caused by different problems: some of them could be settings on the camera, and some of them could be outside influences.

Here is a clip that has flicker:

I can't figure out how to make the light stay the same when the car comes through.

Re: How do I avoid Light flicker in my brick films?

That could be one (or both, I guess) of two things:

- Bright reflections from the white car into the lense, making the scene a whole lot brighter. (Think of it as looking at a car and having to squint because the sun reflects off of it very brightly.)
- Your camera automatically adjusting the brightness of the picture because a light object came into it. (The camera is trying to adjust for the extra brightness.)

Now I've tried looking at it a bit more closely. Here's two (almost) consecutive frames:

This would suggest that it's an issue with your camera's settings: the brightness goes down after the car is out of the shot. Make sure settings like exposure and gain (or just brightness) are fully manual. There also might be something going on with the white balance: in the first frame, the floor seems to be more yellow or orange than later. Make sure the white balance is on manual too.

Great thanks!
