DSLR Color Flicker Problem
Does anyone know what may be the cause of this DSLR color flicker issue? This was shot with a T2i and a Canon 17-55 lens. The focal length was at 17mm for this shot. I did have a Hoya Super Multicoated filter on the front. No ND filter was used. I was using a glidetrack to track slowly towards the church. I am noticing a color flicker around the top edge frames of the door. It’s almost like the lens or camera are confused as to which color to stick with (flickering from brown to black.) Anyone know what is going on? I noticed when the camera stopped moving, the flicker stopped as well. It has something to do with the movement of the glidetrack and the camera/ lens. Is this normal? See the link below: You need to make the image full screen to see what I am talking about around the door frame mostly.Your feedback is much appreciated.

Thanks Jason. So you don’t think it is a defect in the lens right?

DSLR’s, in general, have problems with moiré and that’s what it looks like to me, so no it’s not your lens.

Moire problem, something you have to aware of with DSLR video. Most commonly occurs on fine line detail such as your example. It’s caused by the need to “line shed” pixels and reduce the frame pixel size to 1920 x 1080.
Try the DSLR Moire filter here; https://colorbyjorg.wordpress.com/plugins/
Be careful not to apply it with too high settings it may affect the colour balance of the whole image.

Or… you can just shoot with the Panasonic GH2 🙂

Most people would agree to reduce the internal camera sharpening of your Canon to absolute minimum to reduce moiré a bit. You can reintroduce sharpness (if at all needed) in post.

I dont mean to steal this thread, but i have a related issue (i think).
I shot this TL fully manually with the Nikon D7000, Nikkor 10-24mm lens, f/10, shutter 1/160. Shot in raw, batch processed with capture NX to TIFF, imported as sequence in AE and exported uncompressed, then compressed to h264 with QT.
Any ideas regarding the reason for color/brightness flicker in this timelapse?

Hey Peter,
How would you recommend reintroducing sharpness in post? I have Final Cut Pro. Just wondering how you do it, and what settings you use.
Thanks!

Kristian, your problem is not moire.
Your problem looks like something to do with exposure or changing light from frame to frame as the whole picture frame is changing in brightness.

Im new to DSLR timelapse and now understand that the flicker issues is related to small variations in apperture when shooting the sequence.
I downloaded GBDeflicker Trial and applied it to the allready exported file just to test, and must say im relatively happy with the result (default settings in GBDeflicker). Although i would like to solve this before PP (have read that longer shutter/ND filter perhaps can decrease the variations in apperture)
Thanks!
