【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：

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

HandBrake
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
其中的全部的log输出：

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：
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
模拟电视标准 | 分辨率 | |
720×576 | 5:4，非正方形的像素 | |
PAL VHS | 320×576 |
数位电视标准 | 分辨率 | |
D-1 NTSC (square pixels) | 720×540 | |
PAL | 720×486 | |
D-1 PAL | 720×576 | 4:3 |
D-1 PAL（正方形像素） | 768×576 |
数位电影标准
DVD “PAL” | 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：
20180825 01:26:23
