De-interlacing on progressive video

Hi Ran,

Which device and which SDK (EZSDK, IPNC RDK, DVR RDK) you are using?

Best regards,
Pavel

Hello,

Ran S. said:

Is it OK do de-interlacing on progressive video or does it result in bad video ? 

 In EZSDK capture_encode demo we have DEI connected after the capture component. The DEI operates in two mode:

 DEI in deinterlacing mode
 DEI in progressive bypass mode

Hi Pavek,

I'm using RDK 4.2.0.

I know there is capability to skip de-interlacer in case of progressive input, but I also interested in knowing the result of applying deinterlacing on progressive video.

Thanks,

Ram

No you should not enable deinterlacing on progressive video. It will result in very bad video quality as the deinterlace algorithm assume successive input fields are temporaly separated interlaced content and tries to extrapolate progressive frame from interlaced fields. What is your usecase for doing dei on progressive content.

Hi Badri,

The problem is I just don't have the original camera which output interlaced video... so I though of using some video generator, but not sure if I have any source which is interlaced right now.
If you have some idea for video generator to interlace 720x480 30fps , please tell me.
Do you think I can use laptop output for this purpose (I suspect it always output progressive video) ?

Thanks

Ran

Thanks very much for the suggestion , Badri.
