I'm getting very bad streaming quality from Emby in scenes that feature a lot of movement and individual objects. I have the transcoding setting set to highest quality (except for CRF which is 1 instead of 0, else nothing plays). My server's CPU usage is <5%, so that's not throttling the transcoding.

 

The quality only drops during fast scenes or scenes with a lot of detail, and the drop is significant enough to disrupt pretty much any movie or TV show. Movies with lots of on-screen details are nearly unwatchable.

 

How can I correct this?

Hey Luke, I enabled debug logging and attached the two log files that were generated when I went to play the video. Thanks.

Ok, we're making some adjustments. Please try again with the next release of Emby Server (with those server transcoding settings back at default). Thanks !

What kind of changes are necessary, or what was the problem? I feel those are important distinctions to make, less "ethereal".

What is your Max Streaming Bitrate setting in your client? Is it set to Auto or a specific bitrate?

Adjustments to keyframe spacing. This change will not be in the 3.2.30 release headed out today but will be in the following release, thanks.

It's set to auto, but it's selecting the highest quality available (720p 10Mb/s). Selecting it manually makes no difference. Though the files bit rate is only 2.5Mb/s
