Consumer cards often "stutter" when writing video because their speed fluctuates. SXS video requires a sustained write speed (often 800Mbps or higher). This ensures that high-bitrate 4:2:2 10-bit video (professional color space) records without dropping a single frame.

The concept of SXS video originated from the need to compare and contrast different products, services, or ideas. It is believed to have started on YouTube, where creators began experimenting with the format to provide a more comprehensive review or comparison of products. Over time, the format gained popularity, and SXS videos started appearing on various social media platforms, blogs, and websites.

Simply copy-pasting files from an SXS card to your desktop can lead to corrupted metadata or broken clip structures. You need a proper offload strategy.
