When you are streaming and recording in OBS Studio at the same time you may want to Remux recordings but what does this mean? Well, generally people recording in OBS will record in MP4 file format. This is because MP4 files are easy to work with in post-production. The file type is compatible directly with editing software.

However, when you are streaming for long periods of time you have a risk of losing your recording. If your software crashes during a recording and your video file type is MP4, you will lose the whole recording. If you record in a file type such as .MKV and the software crashes, you will be able to recover your footage.

OBS has a feature built-in where you can record your footage in MKV file format and then Remux the recordings to MP4 when you are finished with the recording. This protects you if your software crashes mid recording.

Let’s jump in and show you how you can Remux recordings in OBS Studio.

What Is Remuxing In OBS Studio

The Remux feature in OBS Studio allows you to record footage in .mkv or .flv file formats which are less likely to corrupt. The Remux feature will then convert these files to MP4 once the recording is complete meaning you can use them in your editing software.

You have successfully converted your .MKV or .FLV file to an MP4 which can easily be used in editing software or to upload your footage online.

What Are The Benefits Of Recording In MKV On OBS Studio

The main reason people use mkv files in OBS is to prevent corrupted files. A mkv file is much more likely to survive a system or software crash than an MP4 file which is easily corrupted. Streamers like to use MKV files as they won’t lose hours of recorded footage if their system does crash. This can be huge if they hit some insane clips or had some hilarious moments during that recording or stream.

Wrapping Up

You now know how to Remux recordings in OBS Studio. If you plan on having long streaming or recording sessions it’s good to have some sort of contingency plan in place if your system crashes. Using MKV files is one way to do this. You can then convert them to MP4 after your stream for easy use in editing software.
