Moire and aliasing issues on Canon 6D

Tariq Peter · February 20th, 2013, 10:12 AM

Sound is in all honesty the one thing I am consistently adjusting at weddings. Having to stop recording to increase the input level would be a little bit of a nightmare for me.

The only one of the canons you can adjust sound on while recording is the mkIII unless you use ML...

I want to make short clip to show the Moire pattern on 6D. Let me tell you, I tried many things in the house but couldn't find any that shows lots of Moire. I tried fabric, screen door, texture wall... Then see some on my luggage. So I did this test.

I noticed the pattern is less obvious switching from Standard picture profile to Neutral. And it gets even less when setting Contrast all the way down to -4 in Neutral. It's very difficult to see it here because of the mp4 artifact.

For taking pictures the camera is wonderful and I can highly recommend it.

To show the moire and aliasing issues I uploaded this simple clip.

As I thought this might be of general interest I shared it as this buying and selling costed me more pennies then I liked.

Just curious - did you try shooting with the sharpness slider all the way to zero and sharpening it up in post? This is what I do with the 5d3.

If we look at resale value of the 6D and the MK3 would the MK3 not be a better investment all round?
The price of the MK2 is still quite high but I image the 6D will drop quite considerably over the next year as the Rebels do.

This is an issue for me as well. I know the downsides of going "auto" but I did some tests and found that if you record in "auto" with the attenuation turned on it does a much better job of evening everything out. It seemed to get rid of the wild swings, and wind noise. I used a SONY wireless mic. I am not an audio expert and attenuation me be more of a feature used with line inputs, but all I can tell you is that it sounds loads better recording in "auto" with the attenuation turned on.

I could be wrong but I though the 5d MarkIII and the 6d shared the same image processor. The MarkII beats the 6D as a stills cam but not in quality of video. The MarkIII also has a headphone jack which might make it worth the price. I have a 6D and love it, but i do miss the headphone jack.

I'm using RODE VideoMic Pro. It has three levels audio switche, -10db, 0db, and +20db. The +20db is created for DSLR. With such, just set the audio level on DSLR one notch above zero. Then use the microphone's +20db for the amplification.

The processors might be the same but the "processing" is different. The 5D3 removes aliasing. The 6D does not.
