How to compress MP4 files

Step 1

Upload your MP4 files

To reduce MP4 size, first you need MP4s to compress. Upload those video files to Descript’s workstation. If you have other file formats, like MPEG or MOV, go ahead and upload them since Descript works as a video converter too. 

Step 2

Trim or edit as needed

Before running your video through the file compressor, you can easily trim it using the transcript editor—it's just one more way you can reduce the file size without affecting quality. After all, a shorter video requires less encoding, and Descript’s automatic transcription makes editing as easy as editing a doc.

Step 3

Finally, to compress your video for social media, your website, or cloud storage, click Publish > Export.  You’ll have the option to set the video’s resolution and dimensions of your exported video, or publish it directly to YouTube. You can also share it as a web link, which lets anyone view your MP4 online or download it.

FAQs

How do I change video size while editing?

You can take steps to reduce your file size before you run it through the video compressor. By selecting the “Video settings” button, you can change the frame rate and resize the video. This allows you to edit your video with a better idea of how it will appear, so you won’t end up unpleasantly surprised by the quality loss. It may not be as big a deal as you initially thought.

What else can you make in Descript?

If you’ve finished your video, you may ask yourself, “does this even need to be a video?” MP4 file sizes are small, but not as small as non-video files like GIFs, which you can easily make in Descript if your concept doesn’t need sound. And if the video doesn’t add that much to your podcast, you can export it as an audio file. If the only thing you really need from an interview is the transcription, the transcript is right there, so you might as well export it.

Can I compress an MP4 video file for free?

Anyone can use Descript as an MP4 video compressor for unlimited uploads. We’ll give you three hours of transcription free.
