Control deinterlacing with Wowza Transcoder

This article describes how to control the way Wowza Transcoder in Wowza Streaming Engine™ media server software deinterlaces incoming video.

To control how the transcoder deinterlaces incoming video, add the following parameter to the Decode/Video/Parameters section in your transcoder template:

<Parameter>
	<Name>deinterlace</Name>
	<Value>512</Value>
	<Type>Long</Type>
</Parameter>
Possible values are:
 
  • 256: field interpolation top
  • 768: field interpolation bottom
  • 512: vertical smoothing
Add 2048 to the above value to reorder fields.

For example, to turn on field interpolation bottom with field re-ordering use the following <Parameter>:
 
<Parameter>
	<Name>deinterlace</Name>
	<Value>2816</Value>
	<Type>Long</Type>
</Parameter>
The values are a bit odd because these are bitwise values.
