• The file size of a 4K 120FPS video can vary based on compression codec, bitrate, and video length.
• A minute of 4K 120FPS video using the H.265 codec at a high bitrate might be around 1-2 GB, while using H.264 could result in a larger file size of 2-4 GB.
• These are rough estimates and actual file sizes may vary.
• Recording a short test video can provide a more accurate idea of the average file size.
