Zencoder 编码速度预设

Zencoder encoding speed preset

Zencoder网站上据说转码速度有1-5个值:

A target transcoding speed. Slower transcoding allows for more advanced file compression, while faster transcoding is possible by skipping some advanced compression features. Valid values are 1-5.

ffmpeg 站点上,当前预设为:

ultrafastsuperfastveryfastfasterfastmediumslowslowerveryslowplacebo

所以有人可以告诉我,如果我想要编码速度,我必须选择哪个值 'slow'。

根据 Zencoder 支持团队的说法,它是:

1:Slower

2:Slow

3:Medium

4:Fast

5:Faster
