Dear experts：

I use DEI for deinterlacing, but the output has sawtooth and noise. Some parameters are as follows：

filed input resolution ：720*240； input format：Y422 YUYV

frame output resolution：720*480；output format：YUV422 YUYV

The output image is shown in the attachment, please help to see where the problem may be，thanks！！！

Hi,

is it possible to try latest version (3.07):

2.9 is very old and there are a lot of fixes and new features added mean while.

Hi，Yordan

I downloaded the new SDK, But unfortunately i didn't compare the differences about DEI.

Can you tell me the differences about DEI, or is there any other configuration factors may cause the sawtooth.

Thanks!

Hi，Yordan

I also have a question, the DEI output resolution is the size we need, so does the SC need bypass? Thanks！

Hi,

It depends, if you want to use smaller size, then enable scalar or bypass it.
