How to Convert OBS MKV to MP4 Efficiently on Windows?

Instead of converting OBS MKV to MP4, you can also directly make OBS record in MP4 format by changing the default recording formats of OBS. However, it is not suggested to do so. As OBS illustrated, the recordings saved to MP4 formats will be unrecoverable if the file cannot be finalized for some reason (e.g. BSODs, power losses, etc.). That means, if OBS or the computer crashes, or if the disk is fully occupied, the recordings in MP4 format will lose every frame. But this is not the case with MKV. So you’re recommended to record screens in MKV format and later convert OBS recordings to MP4 format.

If you’re persistent on making OBS videos MP4 format, just follow the instructions below to see how to make OBS record in MP4.

Step 1: Launch OBS and find File on the top menu bar. Tap on Settings and navigate to Output section.
Step 2: Find Recording Format and choose MP4 from its drop-down list.
Step 3: Change the Recording Quality if needed, as the default setting “Same as stream” doesn’t allow you to pause the recording.
Step 4: Tap OK to save the changes and now the OBS recordings will be saved to MP4 format.

If you leave the default output format as MKV, you can remux MKV to MP4 later in OBS Studio or with other video converters. In OBS, you can choose to automatically or manually remux MKV to MP4. Below is the how-to tutorial for each way.

Step 1. Open OBS and tap on File. Find the Settings and head to Advanced in the pop-up Settings window.
Step 2. Move to the Recording section and check the “Automatically remux to MP4” box.
Step 3. Hit OK to save the changes, and the auto MKV to MP4 is activated now!

Step 1. Run OBS and click File on the top menu bar, then select the Remux Recordings option.
Step 2. Add the MKV recording to the interface by clicking the three-dotted button under the OBS Recording section.
Step 3. Click the three-dotted button under the Target File to select an output path and rename the recording.
Step 4. Press Remux to start the process.
