How to Use OBS Recordings Remux: Full Introduction and Guide

Open Broadcaster Software (OBS) is one of the leading recording programs that most people use today. This software is a solid option for content creators looking for a tool to help stream their content to video streaming sites. Another function that most OBS users often like is the tool’s built-in recording feature, which can be used to capture computer screens and webcam footage. When looking for additional features, one slightly overlooked offering available in the software is the OBS Remux Recording feature. This option works as a file converter tool, which can be used to convert OBS recordings saved in MKV format by default into more common file formats that are easier to read, such as MP4. If you are interested in using this option, please continue reading the article down below.

Remux OBS Recordings

Part 1. What is OBS Remuxing

OBS Remuxing is the built-in option of the OBS recording tool to convert recorded video files into five different formats that the tool supports. Since OBS video recordings are saved in an MKV file, the most common usage of remux recording is to convert these videos into an easily readable format, such as an MP4 file. In addition to MKV and MP4, this OBS function can also be used to convert files into FLV, MOV, and TS.

To learn the factors that make OBS remuxing worthwhile, make sure to read the factors that we have selected below:

OBS Recording Format

By default, OBS recordings are saved in either MKV or FLV. These formats are selected since they are more resistant to file corruption in case OBS faces errors or crashing issues. Neither of the mentioned formats is easily corrupted in case your computer shuts down during recordings.

Post-Editing Format

Although MKV and FLV are advantageous for recording preservation and avoiding crashes, they are unfortunately not compatible with most traditional video editors. When it comes to mainstream video editing software like Premiere Pro, Final Cut, DaVinci Resolve, and others, the most advisable video format is MP4.

Why Use Remuxing

The most reasonable cause for why remuxing is needed is to make your OBS recordings compatible with video editors. Fortunately, OBS offers format remuxing to highly supported video formats such as MP4 and MOV.

To learn how to use the Remux Recording function of the OBS recorder, we have featured a detailed tutorial on how to use this tool in the next section of this article.

Part 2. How to Remux in OBS

Remuxing recordings in OBS is surprisingly simple to do, especially for a program that was designed to cater to users with technical experience. In fact, the procedure of MKV conversion in OBS can be done within three simple steps. However, learning was file format the software supports is quite tricky to learn for first-time users. This is because the supported formats in the OBS file converter were not specified. Fortunately, we provided all the supported formats of OBS in the third step of this guide.

Without further ado, please continue reading the guide below to learn how to use the remux recording feature of OBS.

Remux During Recording

1. Start recording on OBS and then select File > Settings.

You can also click on the Three Dots button to set the save location of the video. If all the desired settings have been set, simply click on Remux to start the file conversion process.

Obs Remux Recording Format Remux

Although OBS’ converter function is surprisingly simple to use, the file format that it can convert to is simply limited. Additionally, it does not support video-to-audio conversion, which is a highly practical conversion format that is useful for media production needs. To learn which is the best OBS alternative file converter that you can use, please read the next section of this article.

Part 3. OBS Alternative to Convert OBS Recordings

Since OBS is a recording software and its file conversion process is only a bonus feature, it is understandable if its limitations are quite low. If you are looking for a more powerful file converter tool, look no further than AnyMP4 Video Converter Ultimate, which will be the featured topic of the third section of this article.

Designed as an exclusive file converter, AnyMP4 Video Converter Ultimate is for users who want to convert various media files to multiple formats. Additionally, the tool can remux files to a different format, such as MKV to MP4. This feature opens up many possibilities, especially for multimedia practitioners such as media editors.

Although OBS offers security and professionalism thanks to its crash-resistant formats, the cost of additional steps to make recorded videos accessible for video editing may be too high. It also helps that remuxing is another skill users need to learn first. With that in mind, AnyMP4 Screen Recorder offers a one-stop solution that automatically records videos in a universal format with no extra remuxing required.
