Make OBS Save As MP4

Here are two ways that allow users to make OBS recordings save as MP4 videos. Users can change the video format on OBS for recording to MP4 format or remux the recorded MKV video to MP4 format. Just read on to see how to make OBS save as MP4 in different ways.

Method 1. Change Defaul OBS Recording Format to MP4

Although OBS set the default recording format as MKV, it also supports FLV, MP4, MOV, and other formats as the output recording format. Just follow the steps below.

Step 1. Launch OBS and go to “File” > “Settings” > “Output” from the top menu bar or open “Settings” under the “Controls” bar at the bottom right corner.

Step 2. Find “Recording Format” under the “Recording” tab and choose “MP4” as the output format.

Optional: Change the Recording Quality if needed as the default setting “Same as stream” won’t let you pause your recording. If you don’t want to keep this, switch the Recording Quality to “High Quality”, “Indistinguishable Quality”, etc. at your will.

Step 3. Tap on “Apply” to save the change.

How to Change OBS Recording File Type

Now you can start the screen recording in MP4 format without converting the OBS MKV recording files. But in fact, it is not recommended to make OBS record in default MP4 format as there may occur some recording issues. When changing the recording format from MKV to MP4, you will see a warning message at the bottom of the interface saying that “Recordings saved to MP4 will be unrecoverable if the file cannot be finalized (e.g. as a result of BSODs, power loss, etc.)." And you’re recommended to remux OBS recording to MP4 afterward.

Method 2. Remux OBS MKV to MP4

OBS must have its reason to set the default recording format to MKV. For instance, MP4 is not a recording-safe format. But it offers an option that allows you to record in MKV and then remux it to MP4 afterward. Only one more step is required and you can get the MP4 OBS recording without issues. Newer versions of OBS come with a setting to automatically remux to MP4 when you stop recording. Here's how to remux the OBS recording to MP4 video format.

1. Automatically Remux to MP4

Step 1. Navigate to the “File” > “Settings” > “Advanced” in OBS.

Step 2. Move down to the “Recording” section and check the “Automatically remux to mp4” box.

Step 3. Hit “Apply” to save the change.

2. Manually Remux to MP4

Step 1. Go to “File” > “Remux Recordings” option in the top menu bar.

Step 2. Click the three-doted button to add the OBS Recordings.

Optional: You can click the files under the “Target File” to bring up the three-doted button to change the output path and rename the recording. You can also just leave it as default.

Step 3. Click “Remux” to start the process.

Automatically Remux to MP4

Note: Although users can remux MKV to MP4 inside OBS Studio, some users complain that the OBS remux MKV to MP4 is not working. Moreover, it may take a long time with high disk utilization if you’re remuxing a multi-gigabyte video. In this case, you can try another screen recording tool to directly record screen in MP4 format. The following shares a handy tool that can help you record MP4 video in high quality. Just have a look if you're interested.

Apart from the default recording format of OBS, there are also some other problems when recording, such as the OBS not recording audio, OBS not recording full screen, etc. Although they can be solved with some remedies, the recording experience will be inevitably influenced. If you are tired of the remuxing process or want to avoid possible recording issues, you can consider using an OBS alternative.
