I'm new to OBS and video capture and production. Thanks in advance for your gentleness and patience!
Could you please help me to understand what video and audio bitrate are? I know that OBS has separate bitrate settings for video and audio, under Settings > Output. For audio, the available choices are 64, 96, 128, 160, 192, 224, 256, 288, and 320 Kbps. For video, on the other hand, it appears that one can specify more or less any integer value.
I noticed that in version 32.0, the default video bitrate was increased from 2500 to 6000 Kbps (see the section "32.0 Changes," change by notr1ch, on this list of OBS releases: https://github.com/obsproject/obs-studio/releases ). Later, in version 32.1, "Changed default bitrates to 6000 kbps [mihawk90]" was stated in the changelog (see the section "32.1 Changes" in this list: https://github.com/obsproject/obs-studio/releases ). Does anyone know why this change / these changes was made?
Wikipedia defines bit rate as "the number of bits that are conveyed or processed per unit of time," with 1 byte = 8 bits. Obviously, in general, the higher the bitrate, the higher the quality/fidelity (and the higher the file size). But how does one know what bitrate values to use?
I'm using OBS to make MP4 (video and audio) recordings of videos playing on my computer system. If the source video (i.e., the video playing on my system) is a streaming video — including, but not limited to, YouTube and Vimeo — how can I determine its video and audio bitrate? Should I use the MP3 audio and video bitrate guidelines / typical values given on the Wikipedia page?
