What can you deduce from this image?
 

Hi, I'm just doing some test with different setups.
I'm curious what can you deduce just inspecting this image.

In the screenshot you can see me, 2 years old. There's a very weird pattern, I don't know why. It appears every time there is low light, but maybe I wouldn't notice it with the equipment I'm going to buy.
The video was shot by a JVC camera, the same that is playing the tape.
The left image was deinterlaced with QTGMC Slower, the right one with QTGMC Faster.
Video captured by Blackmagic Intensity Pro, with Blackmagic Media Express and AVI Motion JPEG codec.

Bad capture card, bad codec, all bad.

Yes, of course I know. I'm waiting for the new equipment I've bought. It's just a test. Have you ever seen that strange pattern? Can a new equipment solve it or it's just an original artifact?
I don't use any TBC. I suppose my new Panasonic ES10 should remove that little weavy perimetral side line

What video cable are you using?

I'm using a composite cable

Looks like "herringbone noise" which is usually related to oversharpening/processing somewhere in the chain. On a CRT, most likely it wouldn't be visible at all.

I guess the question you have to ask is when that noise shows up. Is it after your deinterlace, or was it there before it was deinterlaced?

You might as well try capturing in some other format than motion jpeg and seeing if that gives a different result, such as any of the lossless codecs.

You might also make sure everything is plugged into the same outlet as ground loops can also cause similar noise:

The example above isn't great in that it's also not an ideal capture setup, but it shows that ground loops can affect not only audio, but also video.

Lots of things can throw off a lot of electromagnetic interference with fluorescent and LED lights in particular adding quite a bit of noise to mains as well.

Wow! I had no clue about this herringbone noise.
I tried every other codec possible, lossles and lossy, but the noise was always there.
My pc and the camera were connected to different outlets, you are right.
I must try to acquire the video again, following your advice.

Thank you, in the next days I'll update you!
