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:You have 4 “presets” (Recording Quality) to choose from which explain themselves pretty much and you can switch the output format to your liking:
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:
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:
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:
- 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
- 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
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):
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.
