视频编辑精度:整数时间基解决帧率不准确问题

本文深入探讨了视频编辑中处理帧率所需的精确算术,特别是“23.976 fps”这一常用昵称与其精确分数表示(24000/1001)之间的差异。作者解释了使用浮点数近似这些速率如何引入系统性错误,导致帧随时间漂移。为解决此问题,提出的 FilmCraft 系统使用极高的整数时间基(每秒 254,016,000,000 滴答)来精确表示所有帧和音频采样位置,避免了浮点数不准确性,并确保了不同帧率之间的精确转换。 AI

    23.976帧率并非如此:深入了解ArtCraft的整数时间基准

    <h2> One integer per position, one rational per conversion: a 254,016,000,000-tick timebase keeps a 25 → 23.976 EDL inside half a frame. </h2> <p>A 25 fps edit goes into a 23.976 project. The cuts land where they should — until cut 40, where the picture is one frame late. The fix…
