When 4K recording actually matters (and when it does not)
4K recording is NOT always better. Here is when it matters: 4K MATTERS WHEN: recording code editors with small font sizes (12-14px), showing detailed data visualizations or spreadsheets, recording design tools with fine details (Figma, Sketch), creating content for large-screen viewing (presentations, demos), or you need to crop/zoom in post without losing quality. 4K DOES NOT MATTER WHEN: recording for social media (platforms compress to 1080p anyway), mobile-first content (phones display at 1080p), file size is a concern (4K files are 4x larger), your computer struggles with 1080p encoding, or the content does not have fine details (talking head, simple demos). THE PRACTICAL GUIDELINE: use 1080p for 90% of recordings. Use 4K only when fine detail matters. The quality difference is visible on large monitors but negligible on phones.
4K recording requirements (be honest about your hardware)
To record 4K smoothly, you need: MONITOR: must run at 3840x2160 (4K) resolution. If your monitor is 1080p, recording at 4K captures at 1080p regardless of the setting. CPU: modern multi-core processor (Intel i5/i7 10th gen+, AMD Ryzen 5/7, Apple M1/M2/M3). Older CPUs may drop frames at 4K. RAM: 8GB minimum, 16GB recommended. 4K encoding is memory-intensive. BROWSER: Chrome or Edge with hardware acceleration enabled. Check: chrome://gpu should show 'Hardware accelerated' for video encoding. STORAGE: a 1-minute 4K recording at default settings is approximately 100-200MB. Ensure you have free disk space. THE HONEST TRUTH: most modern laptops (2020+) handle 4K recording fine. Older desktops may struggle. If 4K drops frames, record at 1080p — a smooth 1080p recording looks better than a choppy 4K one.
4K vs 1080p: file size, quality, and practical differences
FILE SIZE: 4K at default settings produces files roughly 4x larger than 1080p. A 5-minute recording: 1080p is about 100-200MB, 4K is about 400-800MB. QUALITY: the difference is visible on large monitors (27 inch+) when viewing side by side. On phones and laptops, the difference is negligible. On YouTube, 4K uploads get a higher bitrate allocation, so the quality advantage is preserved better than 1080p uploads. EXPORT TIME: 4K exports take roughly 2-3x longer than 1080p due to the larger frame size. EDITING: 4K editing requires more processing power. Trimming is fast (stream copy), but effects and transitions require full frame decoding. THE BOTTOM LINE: record at 4K if your hardware supports it and you need the detail. Otherwise, 1080p is the practical choice for most content.
Optimizing 4K recordings for different platforms
YOUTUBE: upload at 4K. YouTube processes 4K uploads at higher bitrates than 1080p, preserving quality better. Your 4K video will look noticeably sharper than 1080p uploads. INSTAGRAM/TIKTOK: record at 4K but export at 1080p for these platforms. They compress all uploads to their own specs anyway. The 4K recording gives you crop flexibility in post. PRESENTATIONS/DEMOS: export at 4K for large-screen viewing. If presenting on a 4K display, the crisp text makes a real difference. ARCHIVAL: export at 4K for your archive. You can always downscale to 1080p later, but you cannot upscale 1080p to 4K. THE WORKFLOW: record at 4K, edit at 4K, export platform-specific versions at the correct resolution for each platform.
How it works
Select 4K resolution
In the recorder settings, choose the 4K resolution option. Your monitor must run at 4K resolution for this to capture at full detail.
Record your screen
Grant screen sharing permission and start recording at full 4K resolution. Ensure your computer has sufficient CPU power for real-time 4K encoding.
Export in 4K
After recording, export the video. Nyxhora preserves 4K resolution in the output MP4. The file will be larger than 1080p — roughly 4x at the same bitrate.
Frequently asked questions
Is 4K recording free?
4K is available to Pro users. Free accounts can record at 720p. Both tiers export without watermarks. Pro also includes 60fps at 4K for smoother motion.
What file size should I expect?
A 1-minute 4K recording at default settings is approximately 100-200MB. A 5-minute recording is approximately 500MB-1GB. File size varies with content complexity and bitrate settings.
Can I record 4K at 60fps?
Yes. Pro accounts support both 30fps and 60fps at 4K. 60fps produces smoother motion but files are roughly 50% larger than 30fps at the same quality.
Will 4K recording slow down my computer?
4K encoding requires more CPU than 1080p. Modern hardware (2020+) handles it well. If you experience frame drops, reduce to 1080p or close other applications to free CPU resources.
