To export a video in 4K resolution using CapCut, you need to adjust the export settings after you have finished editing your project. The process is straightforward on both desktop and mobile versions of the app.
Key Export Settings
Frame Rate: The frame rate (fps) affects the smoothness of your video. For high-quality 4K content, especially for fast-paced action or gaming videos, a frame rate of 60fps is often recommended. If your original footage was shot at a different frame rate, it's best to match it to avoid issues.
Resolution: When you are ready to export, locate the Export button in the top right corner of the screen. In the export settings menu, select 4K from the resolution options. This is the most crucial step for achieving a high-quality, high-resolution output.
Bitrate: The bitrate determines how much data is used per second and directly impacts the video's quality and file size. For 4K video, a high bitrate is essential to maintain sharp detail and prevent compression artifacts. In CapCut, you can often choose a "Higher" or "Recommended" setting. For platforms like YouTube, a bitrate of 35-45 Mbps for 4K SDR or 44-56 Mbps for 4K HDR is generally recommended.
Format: The most common and recommended format is MP4, as it's widely compatible and offers a good balance between quality and file size.
How to Export your Videos in 4K Ultra HD
Finish Editing: Complete all of your video edits, including effects, transitions, and audio adjustments.
Go to Export: Click on the "Export" button, which is usually located in the top-right corner of the CapCut interface.
Adjust Export Settings: In the export menu, you'll see various options to control your video's final quality.
Resolution: This is the most important setting for getting 4K. Select the 4K option, which is typically listed as 3840x2160.
Bitrate: This controls the amount of data in each second of your video. For the best quality, especially for 4K video, set the bitrate to Higher or a specific high value (e.g., 35-45 Mbps). A higher bitrate preserves more detail but results in a larger file.
Frame Rate (FPS): This affects the smoothness of your video. You can choose from options like 24fps (cinematic feel), 30fps (standard for most online content), or 60fps (ideal for fast-paced action). Higher frame rates will result in a larger file size.
Format: The most common and recommended format is MP4 for its wide compatibility.
Important Considerations:
Source Footage: To truly get a high-quality 4K video, your original footage should be filmed in 4K. CapCut's AI upscaling can improve the quality of lower-resolution videos, but it can't add details that weren't there in the first place.
Platform Compression: Keep in mind that when you upload your 4K video to platforms like TikTok, Instagram, or YouTube, they will often compress it. While this can slightly reduce the quality, starting with a high-quality 4K export from CapCut will help you get the best possible final result after the platform's compression.
Device Performance: Editing and exporting 4K video is a demanding task. Ensure your computer or mobile device has sufficient processing power and storage space to handle the large files without lag or crashes.
