Export 60fps and 4K video without uploading anything

Resolution and frame rate

Pick the size under Resolution. Free exports at 720p with a small cutroom_ mark. Starter goes up to 1080p and Pro up to 2160p, which is 4K, both without the mark.

Frame rate is 30 or 60 fps. Choose 60 when you filmed at 60: a phone set to 60 fps, a cooking demo with fast knife work, a workout. Exporting 30 fps footage at 60 adds no motion. You only get a bigger file.

The same goes for size. Footage filmed below 4K gains nothing from a 4K export.

What every export checks

After rendering, Cutroom AI reads the file back and checks it:

• Length matches the timeline, within one frame plus 50 ms.
• Audio in sync: the first audio and video samples land within one frame.
• No black frames, checked every half second.
• No frozen frames at cuts: the frames on either side of each cut differ.
• No clipped words: speech energy at each cut stays low.
• Frame size matches the size you chose.
• Loudness lands within 1 LU of the target.

Loudness and sound

"Even out loudness" brings the export to -14 LUFS, the level most short-form feeds play at, so your video isn't the quiet one in the scroll. Other sound tools sit beside it: overlap audio (J and L cuts, where each cut's sound runs a moment into the next), noise removal, your own music ducked under your voice, and a voiceover you record in the editor.

How to export

1. 01Press Export in the editor.
2. 02Choose the resolution and frame rate.
3. 03Press "Export MP4". The stages read Getting ready, Rendering frames, Checking the file.
4. 04Read the verdict. "Every check passed" means you're done. If a check flags something, it tells you what it found.
5. 05Download the MP4. For several projects at once, use "Export selected" on the Projects page.

Limits

Speed depends on your machine. Rendering happens on your device, so an older laptop takes longer, and 4K at 60 fps takes longest of all. Nothing renders in the cloud.

Some browsers can't encode 4K. If yours has no encoder for that size, the export says so. Drop to 1080p or 720p and it goes through.

The output is H.264 MP4 only. There's no ProRes, no HEVC and no project export for Premiere Pro, Resolve or Final Cut.

A long 4K export needs free disk space. Cutroom AI warns you before starting if the browser reports too little room.

Shape and framing before you export

Resolution is one half of the export. The other is the frame. Cutroom AI exports 9:16, 1:1, 4:5 and 16:9, with presets for TikTok, Reels, Shorts, YouTube, LinkedIn, X and square. When you turn a horizontal recording vertical, the crop follows your face on your device, and you can crop and pan by hand where it guesses wrong.

Auto punch-in zooms on jump cuts and zoom keyframes both render at the size you pick. Zooming into a 1080p frame softens it, so if you plan heavy punch-ins on a 4K export, film in 4K.
