1440p (2K) at 120 fps with H.265 (HEVC): What You Need to Know
Planning to record or stream 1440p (2K / QHD) footage at 120 fps with H.265 (HEVC)? Knowing the exact file size and bitrate before you start saves both time and storage headaches.
QHD at 1440p offers a noticeable quality jump over 1080p without the extreme bandwidth demands of 4K. It is increasingly popular among gaming YouTubers and desktop-focused content. This resolution is particularly favored by tech reviewers and product demo channels.
Recording at 120fps is primarily used for creating smooth slow-motion effects. When played back at 30fps, you get a beautiful 4× slow-motion effect that reveals details invisible to the naked eye.
The H.265 (HEVC) codec offers approximately 40% better compression than H.264 at equivalent visual quality. HEVC cuts file sizes by nearly half compared to H.264, making it the go-to codec for 4K workflows. Hardware decoding support is now widespread on modern GPUs, smartphones, and smart TVs.
With these settings, a 10-minute clip weighs approximately 2.69 GB, while a full hour reaches 16.15 GB. You will need a minimum upload speed of 57.8 Mbps for reliable streaming. The total video bitrate for this configuration is 38.4 Mbps.
