Standard Recording Output Guide
While OBS Studio is strong for broadcasting live to the internet, it is also a great tool for being able to record, either at the same time as streaming or solely for offline usage.
Basic Recording Settings
A majority of the settings can be found under the Output tab of the main Settings menu.
Recording Path is where your recordings will go on your computer. If you’d prefer the file names to not have spaces in them, then you can tick off the Generate File Name without Space checkbox.
Recording Format is the file format that your recording will be output in. MKV is recommended in case of unforeseen issues arising, since MKV will not corrupt the whole file if there is no graceful stoppage of recording.
Recording Quality when in Simple view will let you select what quality you’d like your recording to be at, anything that is not Same as stream will take extra resources from your computer.
When in the Advanced view you can select which audio tracks you’d like to record which can be helpful if you have, for example, copyrighted music in your stream that you don’t wish to have recorded.
Encoder will let you select the encoder type you’d like to use — like the aforementioned Recording Quality open, anything that is not Same as stream will take extra resources. If you select a separate encoder option, then you’ll be able to set its settings, such as bitrate, quality presets and keyframe interval. You’re also able to rescale the output to have a different resolution, but maintained aspect ratio, relative to your canvas size in OBS. Depending on what the specs of your computer is, you’ll have different options available in the encoder menu to feel free to experiment!
Remuxing
If you record in a file format that is not mp4 and want to convert it to mp4 for easy use in the video editing software of your choice or to make it easier to upload to social media, OBS has that built in for you. If you click on File then select Remux Recordings and press the … button to select which video(es) you’d like to remux. After that hit the Remux button and OBS will convert your videos for you, once completed it’ll provide a prompt saying so.
Advanced Settings
In the Advanced tab of the OBS Settings you can choose what the auto-generated filename for your recordings are. By default it will name your recordings by Year, Month (in numbers) and Date, and then show the time with hours:minutes:seconds. If you hover over the text field while selected, you’ll be able to see the full list of variables available to use in the filenames. You can also select Automatically remux to mp4 if you know you’ll always need your videos remuxed. If selected OBS will remux your video as soon as you stop recording
The Replay Buffer filename prefix and suffix are exactly that, a prefix and suffix for the replay buffer auto-generated file. More on Replay Buffers in another article!

Audio/Video Formats Guide
For high quality local recording one should use the best quality hardware encoder available (AV1 > HEVC > H.264) together with high-bitrate AAC or lossless audio (e.g. ALAC).
MKV is the default container and recommended for most use cases, as it can be easily remuxed into a more compatible format. However, fragmented MP4/MOV may be a good fit for most users who wish to simply upload their videos onto platforms such as YouTube or edit them in common software like Adobe Premiere or DaVinci Resolve.
Use the following tables to determine which audio codecs are compatible with which video formats, suited to your requirements:
Containers
| Codecs | H.264 | HEVC | AV1 | ProRes |
|---|---|---|---|---|
| AAC | Any | MP4, MOV, MKV, TS | MP4, MKV | MOV, MKV |
| ALAC | MP4, MOV, MKV | MP4, MOV, MKV | MP4, MKV | MOV, MKV |
| FLAC | MP4, MKV | MP4, MKV | MP4, MKV | MKV |
| Opus | MP4, MKV, TS | MP4, MKV, TS | MP4, MKV | MKV |
| PCM | MOV, MKV | MOV, MKV | MKV | MOV, MKV |
For the purposes of this list, TS also includes M3U8 (HLS).
MKV supports every single codec combination possible in OBS Studio and is the default container. You may want to consider using fragmented MP4 or MOV for better compatibility with video editing software if compatible with your codec choices.
MKV (Default)
MKV is a very flexible container that is compatible with every audio and video encoder supported in OBS Studio. It is failsafe, i.e. an unfinished recording due to power loss or other causes will remain playbale and recoverable. However, it is not well supported in editing software and may reuqire remuxing for use in editing software.
Poor support in editing software.
MP4/MOV
MP4 is the de-facto standard for internet video. MOV is its sister format with slight differences in codec compatibility, mostly favoured on Mac platforms. MP4/MOV require «finalisation» of a file to be playable, if the writing is interrupted for any reason the file may not be recoverable. It is therefore not recommended to record to MP4/MOV directly.
Excellent support in editing software.
Fragmented MP4/MOV
Fragmentation is a method of writing MP4/MOV files in self-contained chunks so that a file does not require finalisation to be usable, allowing it to offer higher compatibility than MKV while being similarly fault-resistant. May require remuxing to work properly in some editing suites when using lossless or uncompressed audio.
Good support in editing software.
FLV
FLV is the container used in RTMP. It has very limited codec support (H.264/AAC) and only supports a single audio track. It is resilient like MKV but rarely supported by editing software.
Poor support in editing software
MPEG-TS/HLS (M3U8)
MPEG-TS is used in various streaming protocols and offers resilience similarly to MKV with lesser codec support. When using HLS the video is written in segments that are individual .ts files plus a playlist that instructs a player on how to read the files. This is largely used in internet streaming.
MPEG-TS is well support in editing software.
HLS has poor to no support in editing software.
Video Formats
| Container | H.264 | HEVC | AV1 | ProRes |
|---|---|---|---|---|
| FLV | ✅ | ❌ | ❌ | ❌ |
| MP4 | ✅ | ✅ | ✅ | ❌ |
| MOV | ✅ | ✅ | ❌ | ✅ |
| MKV | ✅ | ✅ | ✅ | ✅ |
| M3U8 (HLS) | ✅ | ✅ | ❌ | ❌ |
| TS | ✅ | ✅ | ❌ | ❌ |
AV1 in MPEG-TS is being standardised, once finalised it will be available for both TS and HLS outputs.
AVC/H.264 (Default)
H.264 is the default codec in OBS. It is fairly old (standardised 2004), but ubiquitous for web video and will be playable on nearly every device or software. For most streaming services it is currently the only supported codec.
Excellent support in editing software.
HEVC/H.265
Successor to H.264 (standardised 2013), offers better quality at the same bitrate/file size. However, it was not widely supported or used in web streaming due to its more restrictive licensing agreements. It is supported only via hardware encoders in OBS Studio (NVIDIA NVENC, AMD AMF, Intel QSV, Apple VT).
Good support in editing software.
AV1
The newest codec supported in OBS Studio (standardised 2019), offers improved quality/file size over HEVC. Software encoding is available with SVT-AV1/libaom-av1 but requires high end CPUs for real-time compression. Also available via hardware encoders on recent GPUs from AMD (RX 7000 Series), NVIDIA (RTX 40-Series), and Intel (Arc).
Not well supported in editing software yet.
ProRes
Apple’s codec targeted at professional use cases where large file sizes are not a concern, various profiles available depending on quality needs. Supported via hardware and software encoders on Macs.
Good support in editing software.
Audio Formats
| Containers | AAC | ALAC | FLAC | Opus | PCM |
|---|---|---|---|---|---|
| FLV | ✅ | ❌ | ❌ | ❌ | ❌ |
| MP4 | ✅ | ✅ | ✅ | ✅ | ❌ |
| MOV | ✅ | ✅ | ❌ | ❌ | ✅ |
| MKV | ✅ | ✅ | ✅ | ✅ | ✅ |
| M3U8 (HLS) | ✅ | ❌ | ❌ | ✅ | ❌ |
| TS | ✅ | ❌ | ❌ | ✅ | ❌ |
PCM in MP4 is standardised, but not yet supported by FFmpeg and OBS Studio.
AAC (Default)
Like H.264, AAC is fairly old (1997), but very widely supported while still offering decent quality at typical bitrates. Nearly all streaming services use this codec.
Excellent support in editing software.
Opus
Newer and higher quality codec than AAC (2012), and freely licensed. It offers increased quality but worse compatibility.
Mediocre support in editing software.
FLAC
Lossless codec, freely licensed and widely used for music, but not well supported in video files.
Mediocre support in editing software.
ALAC
Apple’s lossless audio codec, well supported in MOV/MP4 and by editing software.
Good support in editing software.
PCM (Uncompressed)
Uncompressed audio, including 32-bit floating point recording support which allows greater flexibility in editing.
Excellent support in editing software.
