【记录】Mac中试用HandBrake转换mpg视频文件为mp4

折腾:
【记录】把大视频mpg文件转换为画质中等文件小点的mp4文件
期间,想要把原始的近4G的mpg高清视频,转换为 文件大小尽可能低的mp4文件,且希望画质尽量高。
已经用了Total Video Converter Lite转换出:
100多M
200多M
400多M
和用Wondershare Video Converter Free转换出
900多M
的mp4了,但是画质除了900多MB的,
其他的画质的确还是差了点。
看到:

HandBrake: Open Source Video Transcoder
貌似虽然很耗时,但是很专业?
不过感觉10倍的压缩比,其实上面的转换器也可以达到了:
从4G的mpg压缩为400多MB的mp4
不过或许专业的Handbrake输出的画质更好?
去试试效果,希望可以实现:
画质很高,mp4文件很小

可以切换preset配置:
然后去看看各方面的配置:
然后根据教程去调节参数看看
把Video的:
Preset从fast改为medium
【记录】Mac中下载MediaInfo查看音频视频文件信息
其中看到:
Frame rate                               : 25.000 FPS
考虑到原始视频是25帧,那么也去把帧率调低为25帧:
参考教程去调节参数:
算了,为了防止压制时间太长,还是不用placebo改为veryslow:
  • Video Encoder:
    • H.264(x264):是目前支持相对最广泛的,压缩效率最好的
  • Framerate (FPS):same as source
    • 原始视频25帧,则输出的也是25帧
  • Quality:
    • Average Bitrate(kpbs):
      • 此处切换为Average Bitrate时,默认是3000
        • 参考教程改为1650
      • 勾选了:
        • 2-pass encoding:
          • 2遍压缩,压缩效果更好
        • Turbo First pass
          • 防止压缩太慢,第一遍压缩尽量快点
  • Encoder Options:
    • Preset:每次切换不同的值,可以看到下面的会输出编码配置的: x264 Unparse …
      • veryslow:尽量慢,这样压缩效果好
        • 但是没用之前的placebo,怕万一耗费时间太长(比如很多个小时?)
然后开始去压制:
Pass 1 of 2, 0.30%(9.22fps,avg 17.39fps, ETA 00h42m22s)
意思是:
第一遍(共2遍),估计还有40多分钟压缩完成
-》那估计第二遍也不会超过第一遍的时间
-》两个加起来,估计也就最多2小时
-》比我预计的很多个小时,要快多了,还是可以接受的。
Docker上显示百分比和剩下时间:
昨晚22:50左右开始的
  • 第一轮压制:
    • 结束于23:28
    • 耗时:38分钟
  • 第二轮压制:
    • 结束于:00:35
    • 耗时:1小时7分钟
共耗时:1小时45分钟

转出的大小:406M
画质,还是不错的:
转换前后的MediaInfo的(Text模式输出)信息对比:
后来才注意到,其实有预览:
-》之后可以在真正转换之前,去预览,看看画质效果的
-》且预览还支持scale to screen的:
点击后 ,开始编码生成15秒的预览视频:
可以精确到毫秒,查看效果:
-》以后再去转换编码之前,还是好好预览,看看效果再说。
由于目的是为了放到国内的网上去在线播放的,而国内网速不够快,
而发现Vimeo中540p的画质也还可以的:
现在再去试试,把1080p转换为540p,看看画质和文件大小如何:
而网上关于520p的尺寸说法是:
视频网站的超清、高清、标清的分类标准是? – 知乎
PAL制式标清:纵向576线=576i/p (720×576, 768×576, 1024×576等)
高清=576×432
480p 576p 被称为SD(Standard Definition)(标清)
显示分辨率列表 – 维基百科,自由的百科全书
https://zh.wikipedia.org/wiki/显示分辨率列表
模拟电视标准
分辨率
720×576
5:4,非正方形的像素

然后发现:
520p的分辨率也不低啊:
720×576 Storage, 1024×576 Display
再换成:
480p30
720×480 Storage, 853×480 Display
然后再去优化参数配置,尤其是Video
默认1500kbps和fast:
改为:
1200kbps + placebo
先去preview:
果然是placebo,光是preview的encoding就耗费好几十秒才能预览:
全屏:
结果Live Preview发现全屏后也是先要再去Encoding才能预览看:
不过已经发现画质有点损失了。
不过发现也是能接受的:
想要看更长一点的内容的预览,
发现是可以设置预览时间的,改为30秒:
再去点击Live Preview:
完全可以接受的,还是可以的。
那就可以去转换了:
现在是:
开始压缩 20180824 22:23
看看最终是多长时间可以压缩好:
最后压缩完毕时间是:
