Nevertheless, MP4 is not a suggested recording format for OBS in spite of its compatibility. Actually, when choosing MP4 as the recording format, you’ll receive a warning message like this:

That is, if something goes wrong or the OBS crashes during recording, the MP4 file will be unrecoverable and unusable as a whole. But if you use FLV or MKV in OBS to record, the situations like that won’t happen.

OBS features an automatic remuxing function that lets you record in FLV but once you’re done recording, OBS will automatically change that FLV file to MP4.

Here is how to activate the Automatically remux to MP4 feature:

Step 1. Start OBS and go to File > Settings.

Step 2. On the left panel, select Advanced. Then on the right side of the window, go to the Recording section. Tick off the Automatically remux to MP4 option.

Step 3. At last, click Apply > OK to save the settings.

Some users complained that the remux feature in OBS failed to work sometimes. They got an error that says Recording remuxed, but the file may be incompletewhen trying to remux FLV to MP4, or MKV to MP4. Since OBS was primarily designed for recording and streaming, you may need a dedicated video converter to remux or convert OBS FLV to mp4 effortlessly.

FAQs

1. How do I convert FLV to MP4 for free?

HD Video Converter Factory Pro comes with a free version—Free HD Video Converter Factory that allows you to convert or remux FLV to MP4 at no cost. The free version doesn’t support Lightning mode and batch mode, so the conversion speed is lower than that of the Pro version when dealing with large-sized files.

Despite all that, it supports a wide range of inputs and offers 500+ profiles along with customizable settings for outputs. Moreover, without limits on file size and input formats, you can use it to convert HD videos and exports without watermark.

2. Is FLV better than MP4 in OBS?

Surely, MP4 format has advantages over FLV in file size and compatibility. But when working with OBS, MP4 is not a suggested recording format. Once a crash occurs or the recording is ended in an improper way, the MP4 recordings will be unusable as a whole. In this scenario, FLV is better because recording in FLV can help prevent corruption files.

3. What’s the best recording format for OBS?

OBS includes 6 recording formats: MKV, MOV, MP4, FLV, TS, and M3U8. By default, OBS uses MKV or FLV to record a video when you first time launch the recording software.

To get rid of possible file corruption problems and get the highest quality possible, MKV and FLV are two of the best recording formats for OBS.

Bottom Line

Though the built-in remux function in OBS allows you to convert FLV recordings to MP4 without quality loss, it doesn’t offer extra options for you to customize conversion settings. Besides, the OBS remux error happens often resulting in a corrupted file or incomplete file.

So, to output the videos with speed and quality, it is highly suggested that you choose the recommended WonderFox HD Video Converter Factory Pro, getting a one-stop solution for video recording, converting, editing, compressing, downloading, and more.

But if you just want a simple and free video converter, then go for Free HD Video Converter Factory.
