Why use Flixier to remove audio from MP4

Add audio to video

This may sound counterintuitive but it is always helpful to be able to add audio to video that is either higher quality or works as background music. To do this in Flixier all you need to do is drag and drop a new audio on the timeline underneath your original video and you’re done.

Fade audio in MP4 videos

In many cases you might just want to add a few effects to the audio of your MP4 video and this is where the power of our editor comes in.  You can add a fade in or fade out effect with a single click and you can even specify how long the fade effect will take to play out.

Edit MP4 audio

Going even deeper into editing you can cut or trim MP4 audio or you can apply other effects like increase volume, gain, or go pro with our equalizer. The equalizer does come with presets but you can also go full on custom mode if you wanted to.

Edit at super speed 

Because Flixier is cloud powered it means that it is not dependent on your computer hardware to run smoothly. You can effectively edit MP4 video smoothly even on old computers or low powered laptops. There is no reason to spend a ton of money on hardware anymore.

Remove sound from other files types

With Flixier not only can you remove sound from MP4 but you can also remove it from any other video file. Simply add it to Flixier and we will handle conversions and other complicated stuff. Even better, when you save the new video it will come out as MP4 making it compatible with almost any device or social channel available.


I’ve been looking for a solution like Flixier for years. Now that my virtual team and I can edit projects together on the cloud with Flixier, it tripled my company’s video output! Super easy to use and unbelievably quick exports.

Steve Mastroianni -

My main criteria for an editor was that the interface is familiar and most importantly that the renders were in the cloud and super fast. Flixier more than delivered in both. I've now been using it daily to edit Facebook videos for my 1M follower page.

Evgeni Kogan

I'm so relieved I found Flixier. I have a YouTube channel with over 700k subscribers and Flixier allows me to collaborate seamlessly with my team, they can work from any device at any time plus, renders are cloud powered and super super fast on any computer.
