1080p (Full HD) at 120 fps with H.264 (AVC): What You Need to Know
Planning to record or stream 1080p (Full HD) footage at 120 fps with H.264 (AVC)? Knowing the exact file size and bitrate before you start saves both time and storage headaches.
Full HD at 1080p is the most widely adopted resolution for online video. It strikes the ideal balance between visual clarity and manageable file sizes, making it the default for platforms like YouTube, Twitch, and Vimeo. This resolution is particularly favored by corporate video producers and online educators.
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.264 (AVC) codec offers universal hardware and software compatibility across all devices, browsers, and platforms. As the baseline codec, H.264 produces the largest files among modern streaming codecs but guarantees playback on virtually every device manufactured in the last decade.
With these settings, a 10-minute clip weighs approximately 2.24 GB, while a full hour reaches 13.46 GB. You will need a minimum upload speed of 48.2 Mbps for reliable streaming. The total video bitrate for this configuration is 32.0 Mbps.
