Enable double-rate deinterlacing in the Wowza Streaming Engine Transcoder

Double-rate deinterlacing uses the individual interlaced fields to create frames at twice the original frame rate of the video. The advantage is that for high-motion video such as sports, motion is more fluid. The disadvantage is that the quality of each frame can be a bit lower.

Note: This feature is in Wowza Streaming Engine™ media server software 4.0.6.02 and later.

To turn on double-rate deinterlacing in Transcoder, add the following parameter to the Decode/Video/Parameter section of your Transcoder template:

<Parameter>
    <Name>deinterlaceDoubleRate</Name>
    <Value>1</Value>
    <Type>Long</Type>
</Parameter>

When enabled, you'll see the following log statement:

TranscoderWorkerVideoDecoder.init[streamname]: Double rate deinterlacing is enabled for this incoming stream.
