OSS encoders (x264, Theora, VP9, Daala, Vorbis) already tend to have a constant quality rate control mode that they&#x27;d very much prefer you use unless you have an actual reason to need a specific bitrate. I&#x27;m always surprised at how many people try to reinvent it via abr...<p>Netflix (and streaming services in general) on the other hand needs known bitrates with known constraints so their bandwidth estimation can work correctly without hiccups. Your personal video collection does not.
