1440p (2K) at 120 fps with Apple ProRes: What You Need to Know
Streaming or recording at 1440p (2K / QHD) resolution and 120 fps with the Apple ProRes codec? Here is everything you need to know about file sizes, bitrates, and recommended bandwidth.
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 Apple ProRes codec offers exceptional editing performance with minimal quality loss, designed for post-production workflows. ProRes is an intra-frame codec, meaning each frame is independently compressed. This makes scrubbing and editing buttery smooth but results in much larger files. It is a production codec, not a delivery codec.
With these settings, a 10-minute clip weighs approximately 4.48 GB, while a full hour reaches 26.88 GB. You will need a minimum upload speed of 96.2 Mbps for reliable streaming. The total video bitrate for this configuration is 64.0 Mbps.
