提供了 Anaconda 仓库与第三方源（conda-forge、msys2、pytorch等，查看完整列表）的镜像，各系统都可以通过修改用户目录下的 .condarc 文件。Windows 用户无法直接创建名为 .condarc 的文件，可先执行 conda config --set show_channel_urls yes 生成该文件之后再修改。Anaconda安装教程1、选择安装<img decoding="async" class="rich_pages" data-src="https://img.zhanlian.net/wp-content/uploads/2022/11/20221124173139-82af6.png" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="Anaconda" alt="Anaconda" crossorigin="anonymous" data-ratio="0.7610441767068273" data-s="300,640" data-src="https://mmbiz.qpic.cn/mmbiz_png/LoQxIpbk4adqHsBvF3v7b6wk7hYMriarxSeRRZ8vNPzy8IVEwgp1pAx6Q8hzz7EibztjVtMmHbzwibUIbDreU1dRg/640?wx_fmt=png" data-type="png" data-w="498" data-index="1" data-origin-display="" data-fail="0" />2、直接选择next下一步开始安装**<img decoding="async" class="rich_pages" data-src="https://img.zhanlian.net/wp-content/uploads/2022/11/20221124173143-ab048.png" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="Anaconda" alt="Anaconda" crossorigin="anonymous" data-ratio="0.7826961770623743" data-s="300,640" data-src="https://mmbiz.qpic.cn/mmbiz_png/LoQxIpbk4adqHsBvF3v7b6wk7hYMriarxwdSfLySI7tg9w6nSodsPkMZCkeh8sakdW8Ze43Z2oicz6KJJ3aKJ4cA/640?wx_fmt=png" data-type="png" data-w="497" data-index="2" data-origin-display="" data-fail="0" /><img decoding="async" class="rich_pages" data-src="https://img.zhanlian.net/wp-content/uploads/2022/11/20221124173143-45c2a.png" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="Anaconda" alt="Anaconda" /><img decoding="async" class="rich_pages" data-src="https://img.zhanlian.net/wp-content/uploads/2022/11/20221124173143-c4302.png" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="Anaconda" alt="Anaconda" />3、注意安装路径需要为字母，否则会报错的<img decoding="async" class="rich_pages" data-src="https://img.zhanlian.net/wp-content/uploads/2022/11/20221124173143-93443.png" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="Anaconda" alt="Anaconda" /><img decoding="async" class="rich_pages" data-src="https://img.zhanlian.net/wp-content/uploads/2022/11/20221124173143-d1c43.png" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="Anaconda" alt="Anaconda" />4、注意需要添加add Path这个选项，非常重要<img decoding="async" class="rich_pages" data-src="https://img.zhanlian.net/wp-content/uploads/2022/11/20221124173143-66bf3.png" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="Anaconda" alt="Anaconda" /><img decoding="async" class="rich_pages" data-src="https://img.zhanlian.net/wp-content/uploads/2022/11/20221124173144-6618c.png" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="Anaconda" alt="Anaconda" /><img decoding="async" class="rich_pages" data-src="https://img.zhanlian.net/wp-content/uploads/2022/11/20221124173144-9d02c.png" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="Anaconda" alt="Anaconda" /><img decoding="async" class="rich_pages" data-src="https://img.zhanlian.net/wp-content/uploads/2022/11/20221124173144-e6b08.png" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="Anaconda" alt="Anaconda" /><img decoding="async" class="rich_pages" data-src="https://img.zhanlian.net/wp-content/uploads/2022/11/20221124173144-72f67.png" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="Anaconda" alt="Anaconda" />5、安装完成，然后启动软件<img decoding="async" class="rich_pages" data-src="https://img.zhanlian.net/wp-content/uploads/2022/11/20221124173144-da98c.png" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="Anaconda" alt="Anaconda" /><img decoding="async" class="rich_pages" data-src="https://img.zhanlian.net/wp-content/uploads/2022/11/20221124173145-94d43.png" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="Anaconda" alt="Anaconda" />6、如上已经安装并且打开完成7、选上如上的Jupyter Notebook，然后lanuch，就可以启动Jupyter Notebook

HandBrake是基于ffmpeg的视频转码和压缩的多平台开源软件，支持格式多，功能丰富，界面清爽，支持中文。HandBrake内置了中文版的翻译包，打开首选项，可以设置软件所使用的语言。<img decoding="async" data-src="https://img.zhanlian.net/wp-content/uploads/2023/01/20230127165340-c9566.jpeg" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="HandBrake" alt="HandBrake" />使用HandBrake，有两种导入视频的方法，一种是通过左侧的按钮打开视频，另外一种则是将视频直接拖拽到软件中。导入视频后，点击下方的尺寸选项卡，源是导入视频的原尺寸，而下方的宽度和高度则决定了最终导出的视频大小。<img decoding="async" data-src="https://img.zhanlian.net/wp-content/uploads/2023/01/20230127165340-4323f.jpeg" src="https://www.zhanlian.net/wp-content/themes/onenav/images/t.png" alt="HandBrake" alt="HandBrake" />点击预设，可以看到软件内置的各种视频尺寸，方便用户快速进行选择。这些预设的视频尺寸，按照视频发布的平台、使用的设备以及封装格式等类别进行了分类，简直不要太贴心。切换到视频选项卡，右侧的质量有固定质量和平均码率两种选项，这是用于调节视频的码率。视频码率，指的是每一秒视频包含的数据量，码率越大，视频越清晰，它直接决定了视频本身的大小。这里的固定质量，其实就是固定码率，即整个视频下来，它的码率都是保持不变的。而平均码率则是一种可变码率，它会根据画面的复杂程度，更加合理地分配码率，画面越复杂的片段，其码率就相应更高。因此，当你选择了固定质量(即固定码率)时，可以适当降低码率值，来找到视频清晰度和体积大小的平衡点。当你完成了所有编辑，就可以渲染导出视频了，操作如下：先点击添加到队列中，接着点击启动队列，等待视频完成渲染就可以啦。
