Movie problem, can anybody please help me? (screenshot included)
joecaster:
Hi, I just got my 60D.
I did some tests outside and I'm extremely pleased with the result.
Today I wanted to film a music video indoor and I'm getting a distorted image.
I tried lots of different settings but I can't correct the problem.
I have a brand new transcend class 10 card so the card is not the problem I guess.
I'm shooting in the 720p60fps mode.
Here is the screenshot:

Look at the metal stands and the top of the bass drum...
I really don't understand why the result is so bad. :-\
Thank you very much in advance.

Joecaster, can you be more specific about what bothers you in this frame? I see moderate barrel distortion, but I can't say that it's too out of the ordinary - barrel distortion is a fact of life for all wide angle lenses (expensive ones control it better) but if you want truly straight lines, step way back and use a longer lens.
However, I don't even know if barrel distortion is your complaint, or if you are referring to the aliasing (jaggedness) on the edges of the base drum and on the thin bars on the stands. Unfortunately, SLRs are notorious for aliasing problems in video. Long story short, it boils down to this: your camera sensor has say 18MP, and HD video is only 2MP, so the camera discards rows of pixels, to achieve the lower resolution of HD video. The resulting image will suffer from aliasing most evident on thinner straight lines in your frame.
You can help the problem a little bit by lowering the "sharpness" setting on your camera when you're shooting with "everything in focus", but this problem never really goes away completely.
I hope this somewhat helps.

Thanks for replying bro!
I looked for barrel distortion but it's not what I'm talking about here.
I did a bigger screenshot to better show the problem.
Look at the higher edge of the bass drum, the edges of the cymbals, the bottom of the cymbal stands on the left side. It's all distorted and the overall quality is pretty disgusting.

Now the same drums filmed with a Sony HDRCX505 cam with a raynox wide angle:

It looks much better doesn't it?
It's hard for me to beleive that my 60D cannot do what that Sony camcorder does...

The lighting is so different between the images that there is no way to really compare them.
I don't see any distortion, just that the shadows and highlights are different due to the lighting.
