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:
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:
Setup advanced High Quality Settings
Now the interesting settings are in the lower section, but they depend on the selected Encoder:
- Rate Control: CRF
- CRF: 15-25
- CPU Usage Preset: can be lowered to superfast/ultrafast on high cpu usage
- Rate Control: CQP
- CQP: 15-25
- Preset: High-Quality
- Profile: high
AMD VCE [H264 Encoder (AMD Advanced Media Framework)]
- 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, the encoder will be able to just increase its bitrate if necessary to reach a high quality.
- Preset: Indistinguishable or Lossless
- Quality Preset: Speed, Balanced or Quality (Speed is fastest, Quality is slowest)
- Keyframe Interval: 2 - 5 Seconds
- There are also Presets for High Quality, Recording, YouTube and Twitch. These will set up the encoder for that type of usage and will update it whenever a plugin update comes out.
Setup Multiple Audio Tracks
Let us take a look at the option of recording multiple audio tracks. In the advanced recording settings, select Track's 1 to 4. Make sure to also change the Recording Format from flv to a format that supports multiple audio tracks.
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 saved Video right into Adobe Premiere or Sony Vegas for example 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 if you desire to do so.
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.
