关于2.35:1和2.40:1的疑问？
最近下载了一部电影BLACK SWAN，最初下载的版本是Black.Swan.2010.x264.DTS-WAF，音频是DTS的，用KMP死活弄不出声音，倒是WMP可以。然后试着找了找其它版本，然后发现一个问题，就是2.35:1和2.40:1比例都各有几个版本，试着GOOGLE了一下，发现没什么人关注这个问题，想问下，这两个比例是从何而来？都是正规标准么？但是同一部电影发行应该只有一个比例对吧？ 请提供相关文件的下载地址和编码信息。如果你已经下载了，请提供播放画面截图。 版本1：Black.Swan.2010.x264.DTS-WAF.mkv(已下载完成）

另还测试了多个版本就不贴上了，可见不同压缩组对这个细微差别并没怎么在意，大概眼测也不怎么看得出来吧，其实网上下载的视频有很多都是非标准分辨率，比如CHD的480P，TLF的MINISD,也不知道他们是怎么考虑的
PS:为了看这个DTS，让钟情已久的KMP下岗了，谁让新版的KMP内置了插件:@ ，换了POTPLAYER，用下了感觉还不错。操作习惯和KMP很像，并且菜单更简洁。 参考旧帖：[教程] 压片画面比例与字幕调整浅谈
