flicker +wavy lines in Canon Hf 20 video

by lip420 / August 4, 2009 11:31 PM PDT

hi
i need some help. i have got the above mentioned camcorder. a good part of my video has got some kind of wavy lines and flicker in it. flicker is often in building windows, horizontal lines, or when its trying to get a detail of something in the back ground. I have played around with the shutter speed and other controls but i just cant quite seem to get rid of this. read the manual too. i am bummed out since the video has got this. any suggestions?
*much of it can be seen in just the lcd panel.
i have been using this with a Mac and iMovie '09. i am wondering if there is also any way to remove the flicker with some sort of additional software or other way?
i also noticed this sort of flicker and wavy lines in a another stores same model. thus i don't really think it is a defect.

We may need to discuss "how things work."

I wonder if this is what you see when we take a picture and the scene has some horizontal line in it that is slightly at a different angle than our camera's sensors. To explain this I would need a few minutes with a drawing pad, and talk about sensors, scan lines and such but there is nothing amiss here. In fact this area is where film excels for reasons we would again have to dive into how things work.

The LCD display should always be the worst at this effect. Don't rely on that because it's a downsampled image.

But if you will research more about moire patterns and how these things work you will gain the understanding you need.

This issue is well known but eludes some at first.

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
