Streaming quality

[DGDone]

Hey :)

i´m pretty new to Jellyfin. I´m hosting a Server for me and my Girlfriend over the web. I got the Problem that when i stream 4K Files over the Internet it´s always buffering. 
Is there a way to "select" the quality of the Movie? Like in youtube to watch it in 1080P instead of 4K? My Machine is not that powerful, it´s a 4 core intel celeron so probably it´s too slow to live transcode.
What´s the smartest way to do this?

Also is there a way to reduce the Audio channels on a Movie? I only have a Stereo amplifier so i don´t need 7.1 Sound.

The Speedtest of my Laptop in my Home-Wifi is telling me that i have a 22mbps Upload. Is that to slow for streaming 4K? 

It would be awesome if someone could help me with this issue :)

Best regards!

Lowering the quality would require the capability to transcode. Which specific Intel CPU do you have?

Your other option is to re-encode all your media to a lower resolution and bit rate.

Hey!
Okay thank you. I have the: Intel® Celeron® CPU N3150.

Is there a guideline or Tutorial for re-encoding? And if i do this how can i choose between the original and the re-encoded File?

Thank you

Yeah, the N3150 is not really capable of transcoding.

Follow step 6 in this guide. Essentially, you are using handbrake to re-encode the video. What GPU do you have in your "main PC"?

Okay i found a nice cheap PC with a Intel i5-1135G7. That should probably handle transcoding pretty well.
The GPU on my main PC is a GTX1070.

Thank‘s for the hint with handbreak!

So i now have my new Machine running. It still lags when i play that movie. Jellyfin is still direct playing it and not transcode it. How can i set it up that it‘ll transcode it when it laggs? Or is there a way to force transcoding to 1080p when i want to?

The client has to request a bit rate lower than the media's actual bit rate. For example, you have a 5Mbps 1080P video. The client would need to select a bit rate lower than 5Mbps and that would trigger a transcode.

Both the web client and Jellyfin Media Player has the ability to request lower bit rates. As does the Android, Android TV, and (I think) the Roku app. Can't speak for the iOS apps.

Ah okay that´s interesting. Thank you i didn´t know that!
Is there a way to select the resolution of a Movie and live transcode it down to that?
For example if i have a 4K Movie stored on my Harddrive can i watch it in 1080P without having to transcode it manually before?

[TheDreadPirate]

This is what transcoding is. On-the-fly re-encoding to a different codec and/or a different resolution. But the server needs to be setup and capable to do that. Your N3105 was not capable, but the 1135G7 should be able to handle transcoding very well.

I hope so
But is there a way to choose the Resolution? On my android TV, Ipad, iphone and Chrome browser there is no selection tab where i can select the Resolution.
