OBS Studio: High Quality Recording and multiple Audio Tracks

In OBS-Studio you can very easily configure everything for “High Quality” recordings as well as multiple Audio Tracks. We simply need to go into the “Output” settings of OBS. 

Simple High Quality Settings

If you do not plan on streaming and do not want to record multiple audio tracks you can even keep to the Simple Output Mode as shown below:OBS-Studio_Output_SettingsYou have 4 “presets” (Recording Quality) to choose from which explain themselves pretty much and you can switch the output format to your liking:

OBS-Studio_Recording_Quality

And you can also select a different Encoder. This is especially interesting if you have a Hardware Encoder like NVENC or QuickSync available in your System. In this case you will have the option to select them as you can see in my example:

OBS-Studio_Encoder

Now you can change the recording path and recording format to your liking and start recording.

Advanced High Quality Settings and Multiple Audio Tracks

If you want to record multiple audio tracks and maybe stream at the same time switch to the Advanced Output Mode at the top which will give you full control of all the settings:

OBS-Studio_Output_Advanced_Recording

In this mode you can stream and record at different resolutions (currently with the same fps setting), record up to 4 audio tracks and select a different encoder for your stream or recording.

Now the interesting settings are in the lower section, but they depend on the selected Encoder:

x264

  • Rate Control: CRF
  • CRF: 15-25
  • CPU Usage Preset: can be lowered to superfast/ultrafast on high cpu usage

NVENC

  • Rate Control: CQP
  • CQP: 15-25
  • Preset: High-Quality
  • Profile: high

QuickSync

  • Target Usage: quality (lower to balanced or speed if you encounter problems)
  • Profile: high
  • Rate Control: CQP / ICQ or LA_ICQ
  • on CQP: QPI/QPP/QPB: 15-25
  • on ICQ: ICQ Quality: 15-25
  • on LA_ICQ: ICQ Quality: 15-25, Lookahead Depth: 40-50

With those settings, whatever content you record now, the encoder will be able to just increase its bitrate if necessary to reach a high quality. 

Setup Multiple Audio Tracks

Let us take a look at the option of recording multiple audio tracks. Make sure to also change the Recording Format from flv to a format that supports multiple audio tracks.

In the Audio settings you can currently select 3 recording and 2 playback devices in OBS-Studio (you can even add more as sources, but let’s not make it too complicated for a start):

OBS-Studio_Audio_Settings

OBS-Studio_Mixer

And using the little cog wheel I marked in red you can open the Advanced Audio Properties. These allow you to select which audio device should be saved on which track:OBS-Studio_Advanced_Audio_Properties

In the streaming settings we can select one audio track in which all audio devices will be mixed together for your stream. (I use Track 1 in this example.) But for recording (unless we use flv as our format as the warning states) we can save up to 4 separate audio tracks with our video file.

The example shows Desktop Audio, Mic and Mic 2 going to track 1. This track can also be used for a stream at the same time. Track 2 will only record the Desktop Audio and Track 3 Desktop Audio 2 which wont be heard on a stream. Last but not least Track 4 will include Mic 1 and 2. You should be able to load the track right into Premiere or Vegas and change the tracks independently. 

If you use a Capture Card it will also show up in the Advanced Audio Properties if its active in the current scene. So it’s audio can also be recorded on a single track.

As you can see its pretty easy to record at a High Quality with multiple Audio Tracks in OBS-Studio. Be aware if you stream and record at the same time, at different settings, this will increase the CPU load on your system coming from OBS.
