Options not related to to audio, video or muxing cannot be used, for example debugging output.Īnother remark: OBS doesn't seem to be able to output video only or audio only. Then enter the values in the correct option field.

So, if you want to design your custom ffmpeg output option set, first divide your ffmpeg options into the 3 categories above. You see these options as input fields in the OBS configuration dialog. There is an extra input field for this, you don't use the ffmpeg command line option for the bitrate, as well for the audio bitrate. the ones you enter after -c:a on the ffmpeg command lineĪdditionally, some of the options are given elsewhere, for example the bitrate for bitrate-oriented rate controls. In 'Audio Encoder Settings (if any)' you enter audio-encoder specific options, i.the ones you enter after -c:v on the ffmpeg command line In 'Video Encoder Settings (if any)' you enter video-encoder specific options, i.In 'Muxer Settings (if any)' you enter the muxer/container-specific settings.In OBS, you have 3 different input fields for the 3 option types: options for audio encoder (on command line the options after -c:a).options for video encoder (on command line the options after -c:v).options for the container/for muxing (mkv/mp4/etc.-specific options not related to audio and video).To understand the custom ffmpeg output options, you need to understand some ffmpeg concepts. Tune: Not set (My usage is for screencast/instructional videos, would any option in 'tune' be worth setting?) While I could set the audio, the field 'Video Enconder Settings' is empty because I don't know how to deal with FFmpeg syntax for x264 (libx264) and NVENC (h264_nvenc libx264).ĭoes anyone know how to 'translate' to the FFmpeg syntax the following settings from OBS standard interface (attached snapshots)? For recording WAV audio I was led to use Output>Recording>Type '(Custom Output FFMPEG)'
