Interlacing issues

[HawkMultimedia]

Here are two screen shots of the program window, one with deinterlacing on, the other with it off. Off looks better until there is movement, then you can see what looks like interlacing issues around the edges.

SD source via Dazzle DVC100, however, I have also tried when connected via Intensity Pro and gotten the same results.

System specs:
Dell Studio XPS 435MT w/ Intel Core i7 940 @ 2.93GHz
8GB of RAM, 64-bit Win7
NVIDIA GeForce 9500GT w/1GB

I've tried different video cards and multiple machines (dual core and i7 laptops, and a quad core desktop). I thought the Intensity Pro would solve it and was very disappointed when it didn't.

Would appreciate any help.

Thanks,
Patrick

Patrick,

Are you using the same camera with all tests? What camera?

[HawkMultimedia]

Hi Tom,

I was going to say yes, Canon GL2's. But, right now, I'm being fed by a Sony (not sure of the model number). That's what's shooting in the screen shots.

Thanks,
Patrick

Have you tried different cams other than the Sony and the GL2?

A Google search lists 103,000 hits for "Sony deinterlace problem"

What model Sony?

I do not see interlacing artefacts in the second picture? Only see the lower vertical resolution (which is a side effect of the current deinterlacer).

[HawkMultimedia]

So, if it's a side effect of the current deinterlacer, the Osprey cards are the only way around it at the moment?

That, or use a camera with progressive video output.

As Mike pointed out, using cameras with progressive output is by far the best solution to avoid any artifacts from deinterlacing, and also gives you a higher resolution from your cameras. On productions for the web there are no real benefits using interlaced video. If possible, always go for progressive video all the way from the cameras. You will find the output to be alot more crisp and free of artifacts. The saved headacahe avoiding deinterlacing comes as a bonus!
