If you use QuickSync, NVenc or AMD VCE as your encoder, these settings will not work. CRF 0 uses “High 444” mode which a lot of editing software (and some video players) cannot handle. If you wish to increase quality further, you need to use advanced options – quality 10 is equal to a CRF of 22, which is fine for live streams but not so good for local recording.įor compatibility with various editing software, it’s also recommended to enable CFR (advanced options) and do not use CRF 0. Setting the buffer size to zero disables the VBV system, allowing x264 to hit any bitrate necessary to achieve the quality (CRF) specified. A CRF of 0 enables lossless recording which will have very high file size and CPU requirements and introduces compatibility issues, so be careful! Explanation A good place to start is the 15 – 20 range. Use custom x264 parameters: Enabled Custom x264 parameters: crf=X Where X is anywhere from 1-20, lower being higher quality / higher CPU usage. Use CBR: Disabled Quality Balance: 10 Bitrate: 1000 Use custom buffer size: Enabled Buffer size: 0 Advanced Options Do not attempt to use these settings for live streaming! Encoding Here are the settings you are required to change to get high quality local recordings (using the x264 encoder). Some OBS settings are complex to understand, so I leave a recommendation to make high quality local recordings with ease. Sometimes our network or equipment does not allow to overload these tasks, or simply trying to avoid network issues within races we prefer to make a local recording, editing and checking later. As far as I know, a lot of people is using OBS to record and stream their races.
