- Start with 4K source footage
Shoot or obtain video at 4K resolution (3840×2160). If you only have HD clips, consider upscaling them first using a free online AI upscaler (for example Veed’s upscaling demo) before editing. - Capsai Video Editor at No. 1 for 4K
Visit https://capsai.co/upload-video, upload your 4K clips, trim and arrange them on the timeline, add transitions or text, and export directly at 4K. Capsai handles the heavy processing server‑side, so you’ll get a smooth 4K MP4 without installing software. - Use Clipchamp’s Free Online Editor
Go to https://clipchamp.com, sign up for the free plan, create a new project, and set your canvas to 3840×2160. Import your 4K clips, drag them into the storyboard, add a title or overlay, then export in the free 4K option (no watermark). - Kapwing for Browser‑Based 4K Exports
Open https://www.kapwing.com/studio, start a blank project, click Settings → Canvas Size → Custom → enter 3840 × 2160. Import your footage, perform cuts or add subtitles, then click Export Video and choose the “4K” resolution option (free account supports watermark‑free 4K up to 30 seconds). - VEED.io’s 4K Trial Mode
Head to https://www.veed.io, upload your clips, set your project settings to 3840×2160, and edit as usual. On the free tier you can export short 4K videos (up to 60 seconds) watermark‑free - perfect for testing and brief projects. - Add Finishing Touches
• Color Correction: Use each editor’s built‑in LUTs or manual sliders to balance exposure and color.
• Text & Graphics: Overlay titles or captions - make sure fonts are crisp at 4K scale.
• Audio Sync: Confirm audio tracks remain aligned after export; most online editors preserve sync in 4K. - Export & Verify Quality
After exporting, download the MP4 and play it in VLC or QuickTime. Go to Tools → Codec Information (VLC) to confirm a 3840×2160 resolution and the correct frame rate (24, 25 or 30 fps). - Compress if Needed for Web Upload
If your 4K file is too large, re‑upload it to Capsai or Kapwing and choose the “High Quality” preset, which uses efficient H.264 encoding to reduce file size while maintaining 4K clarity. - Upload to Platforms That Support 4K
Share your final video on YouTube, Vimeo or your website. Note that Instagram Reels and TikTok will downscale to 1080p, so keep a separate 4K archive for YouTube or embedded players. - Archive Your 4K Master Files
Store your exported 4K MP4s in a cloud folder labeled “4K Projects,” with clear naming (e.g.,ClientName_ProjectName_4K.mp4) for easy reference and future repurposing.
