Hello,

I wish to achieve to transcoding from 720p60 to 720p30 for an RTMP stream.

I cannot find the setting to lower the FPS, just bitrate, key frame, audio.

Any suggestions? Please. I already checked the tutorial for [transcoder](https://www.wowza.com/docs/how-to-set-up-and-run-wowza-transcoder-for-live-streaming).

Thank you!

Hello there and welcome to the Wowza support forum.

Please take a look at this guide to achieve your desired results:

[How to reduce the frame rate in a transcoded stream (SkipFrameCount)](https://www.wowza.com/docs/how-to-reduce-the-frame-rate-in-a-transcoded-stream-skipframecount%28SkipFrameCount%29)

Eduard, you have to turn on [logVideoEncodingParameters](https://www.wowza.com/docs/how-to-control-transcoded-video-with-video-encoding-parameters).

Then from the output (something like):

```auto
INFO server comment – # long: bit_rate_mode: bit rate stuff: 0=H264_CBR, 1=H264_CQT, 2=H264_VBR or 3=H264_TQM

```

You can then use this information to create a **\<Parameter** \> block to add to the container to change the entropy method being used:

```auto
<Parameter>
<Name>mainconcept.bit_rate_mode</Name>
<Value>0</Value>
<Type>Long</Type>
</Parameter>

```

Regards,

Salvadore

Hello Salvadore,

Thank you very much for the assistance. Works out almost perfect.

Any way to apply CBR on the transcode ?

Thanks,

Eduard

I’m sorry, I am new to the wowza systems.

Could you please give me more details ?

In the transcoding profile I added the logVideoEncodingParameters, then added the you mentioned, but no result.

Hello,

Please open a ticket at: [https://www.wowza.com/support/open-ticket](https://www.wowza.com/support/open-ticket) and attach the [install-dir]/transcoder zipped log for Wowza Support to further investigate.

How to zip log files: [https://www.wowza.com/docs/how-to-create-a-compressed-zip-file-in-windows-os-x-and-linux](https://www.wowza.com/docs/how-to-create-a-compressed-zip-file-in-windows-os-x-and-linux)
