Question / Help Do or avoid resolution downscale?

[luniawar20]

I dont have any problem with streaming at the original resolution, then is it still better to do resolution downscale or avoid it when you can?

Also the speed that viewers need to watch my stream without a buffering is equal to Video bitrate + audio bitrate? Doesnt matter what my video resolution is or my video quality is, what viewers' speed need to be is the total bitrate?

Yes, because when u set a bitrate of 3500 for instance and audio bitrate is 128k, OBS will make your audio 128k and use 3372k to squeeze in video data which when added with audio be around 3500 (if u use CBR).

If u use VBR, the encoder might make data spikes, bumping up the bitrate a few hundred kbps up on spike to make up for the complexity of the scene being encoded...

Oh ok TY.

So only total bitrate & viewer internet matter for viewer to see the stream without buffering or lag.

How about the resolution downscale? Is it better to avoid it when you dont have downscale your resolution?

The max bitrate that you specify in the encoding tab only determine the amount of bits the video encoder would allocate, so if you put 3500 you'd still be averaging 3628 kbps in case both audio and video are set to use CBR (mp3+video cbr) and a little over/under that with aac.

You want to downscale if the content that you're streaming doesn't look good with the maximum bitrate you can use.

Oh thank you hilalpro.

So downscale could potentially improve quality... Hmm.. I will have to play around with different solution/downscales and stuffs. Thank you for your comment.
