How to Export a Custom Resolution Video on CapCut
CapCut gives you more export control than most mobile and desktop video editors in its class. But the custom resolution export feature trips up a lot of users — partly because the options vary depending on which version of CapCut you're using, and partly because "custom resolution" means different things in different contexts. Here's what you actually need to know.
What "Custom Resolution" Means in CapCut
When you export a video in CapCut, you're choosing three things that work together:
- Resolution — the pixel dimensions of the output (e.g., 1920×1080, 1080×1920, 2560×1440)
- Frame rate — how many frames per second (fps) are rendered
- Bitrate — how much data is used per second, which affects file size and quality
Most editing apps lock you into preset options. CapCut, particularly on desktop and Pro tiers, lets you go beyond the standard presets and set non-standard dimensions — useful for platforms with specific aspect ratio requirements, digital signage, or content intended for unusual screen formats.
How to Export at a Custom Resolution on CapCut Desktop
The desktop version (Windows and macOS) offers the most flexibility. Here's the general process:
- Finish your edit and make sure your project canvas matches or is close to your intended output ratio.
- Click the Export button in the top-right corner.
- In the export settings panel, look for the Resolution dropdown.
- If custom dimensions are available on your account tier, you'll see an option to enter manual width and height values rather than selecting a preset.
- Set your frame rate and quality/bitrate level.
- Click Export and choose your save destination.
🖥️ On the desktop version, CapCut supports exports up to 4K (3840×2160) and, depending on your plan, may allow non-standard aspect ratios through manual input fields.
How to Export at a Custom Resolution on CapCut Mobile (iOS and Android)
The mobile version is more constrained than desktop, but it still offers meaningful control:
- Tap the Export icon (arrow pointing up or the export button in the top-right).
- Before exporting, tap the resolution selector — typically shown as "1080p" or similar at the top of the export screen.
- Slide through the available options: 480p, 720p, 1080p, 2K, 4K (availability depends on your device and plan).
- Adjust frame rate independently — typically 24, 25, 30, 50, or 60fps.
- Toggle HDR export if applicable.
- Tap Export.
Truly custom pixel values (like 1350×1080 for a specific niche format) are generally not available on mobile through standard menus. Mobile is geared toward preset resolutions tied to standard aspect ratios.
The Role of Your Project Canvas
A detail many users miss: your export resolution is constrained by your canvas ratio, not just by CapCut's maximums.
If your project was set up as a 9:16 vertical canvas (standard for TikTok/Reels), exporting at "4K" will give you roughly 2160×3840 — not 3840×2160. The dimensions flip to match the aspect ratio you chose at project creation.
| Canvas Ratio | Common Use Case | 4K Export Dimensions |
|---|---|---|
| 16:9 | YouTube, landscape video | 3840×2160 |
| 9:16 | TikTok, Reels, Shorts | 2160×3840 |
| 1:1 | Instagram feed | 2160×2160 |
| 4:3 | Presentation, older formats | 2880×2160 |
| 21:9 | Cinematic widescreen | 3840×1646 (approx.) |
If you need a resolution that doesn't map to CapCut's canvas presets, you may need to set a custom canvas size at the start of your project — not just at export time.
CapCut Free vs. Pro: What's Actually Gated
This is where a lot of confusion lives. Not all resolution options are available on the free tier.
- Free users typically have access up to 1080p export, sometimes 2K depending on the platform.
- CapCut Pro unlocks 4K export and, on desktop, broader access to high-bitrate and custom dimension exports.
- Watermarks on free exports are a separate issue from resolution, but both are affected by your account tier.
The specific features available on each tier can shift with app updates, so it's worth checking the export panel directly — CapCut labels locked options with a Pro badge or lock icon.
Why Your Export Might Not Match Your Settings 🎬
Several factors can cause the actual exported file to differ from what you selected:
- Device processing limits — Older phones may cap at 1080p even if 4K is listed, due to hardware encoding constraints.
- Storage space — High-resolution exports are large. A 4K, 60fps, high-bitrate clip can easily exceed several GB for longer videos.
- Source footage resolution — Upscaling low-resolution clips doesn't add real detail; the export will technically be the resolution you set, but quality won't improve beyond the source.
- App version — CapCut updates frequently. Export options visible in one version may differ in another, especially on mobile.
What Varies by User
The "right" export resolution isn't a fixed answer. It shifts based on factors specific to each person's situation:
- The platform you're publishing to (each has its own recommended and maximum resolutions)
- Your device's storage and processing capacity
- Whether you're on CapCut free or Pro
- The original resolution of your source footage
- Whether your intended output is for web, broadcast, print/signage, or personal use
A creator exporting a 60-second Reel on a mid-range Android has a very different set of practical constraints than someone doing a long-form YouTube video on a high-spec Windows workstation. The export path through CapCut is the same, but the settings that make sense — and the ones actually available — depend entirely on that context.
