Upload your MP4 files
To reduce MP4 size, start by uploading your video files to Descript’s workstation. If you have other formats, like MPEG or MOV, upload them too, as Descript can serve as a video converter.

Trim or edit as needed
Before using the file compressor, trim your content in the transcript editor—another way to cut file size without losing detail. Shorter videos generally require less encoding, and Descript’s automatic transcription makes editing feel like working in a doc.

How do I change video size while editing?
You can adjust your file size before using the video compressor. By selecting Aspect ratio & video settings, you can modify frame rate and resize the video. This way, you can edit while seeing how it looks.
What else can you make in Descript?
If you’re done editing, it’s worth asking if your content needs to remain a video. MP4 files are generally small, but they’re larger than non-video formats such as GIFs, which Descript can create if sound isn’t required. Or you can export as an audio file if the visuals aren’t vital. If all you need is the text, export a transcript with time codes and speaker labels.
