【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

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：

算下来是：3个小时，的确压制速度慢了一半
文件大小是：304M
画质看了看，还行：
后面的带字幕的部分，字母的文字有一点点的模糊：
不过的确还是720p的更加清楚些：
【后记 20180907】
后来遇到个问题，转换1080p的mp4为720p期间，字幕出现部分乱码：
