课程名称：网络、光盘及电脑/电视/游戏机播放的视频压缩 课程概述：该课程针对两类用户设计。如果您是压缩新手，您将学习如何制作高质量视频，以便在网络上分发、在计算机或智能电视/游戏机上观看、插入到iBooks中或刻录到DVD和蓝光光盘上。如果您对压缩有一定了解，该课程将作为解决编码视频时不可避免出现的问题的重要参考，例如网络视频的最佳关键帧设置（第5课）、如何使用x264（第17课）或如何实现HTML5（第31和第33课）。所有课程均包含视频，大部分内容结合了PowerPoint教学和屏幕演示。所有超过十分钟的课程均附有注释，以便您快速找到最重要的内容。大多数课时链接到其他互联网资源。 本课程分为六个主要部分： 1. 术语和技术（95分钟） - 提供编解码器和压缩的概述，基本编码配置（分辨率/帧率/数据速率），以及比特率控制（VBR、CBR）、帧类型（I、B、P帧）和容器格式等配置选项。还探讨音频编码参数（采样率/通道/数据速率）、去隔行和长宽比问题。最后介绍三个免费的必备工具：MediaInfo、Bitrate Viewer和MPEG Streamclip。 2. 编解码器（52分钟） - 简要介绍流媒体、DVD和蓝光及摄像机使用的编解码器及编辑过程中使用的中间编解码器。然后，通过三节课介绍H.264，最后一节课介绍如何使用x264。 3. 编码食谱（62分钟） - 提供特定指导，帮助用户制作上传至UGC/OVP网站、在移动设备播放、本地或电视/游戏机播放、从网站流媒体播放、刻录到DVD或蓝光光盘或插入到iBooks Author的视频。 4. 编码程序（126分钟） - 所有编码程序在制作流媒体视频时都有其独特之处。在这些教程中，您将学习Apple Compressor 4.1、Adobe Media Encoder、Sorenson Squeeze、Telestream Episode和HandBrake的独特性，并高效制作适合目标用途的高质量视频。 5. 分发您的网络视频（34分钟） - 教您如何在网络上分发视频。首先概述分发选项，包括用户生成内容网站、在线视频平台或通过您的网站使用HTML5。然后提供集中式教程，演示如何通过这三种方式进行分发。 6. 优化源视频（68分钟） - 没有高质量的视频源，就不可能有高质量的流媒体视频。在这些课程中，您将学习如何在Premiere Pro、FCP 7和FCP X中优化源素材，并使用Neat Video滤镜去噪。接着，您将学习如何在Audition、FCPX和iZotope RX3中清理音频，其中 iZotope RX3 的音质最佳。倒数第二课讨论音频压缩，这一技术可以提高编码音频的清晰度，最后一课展示如何处理音量过大的录音音频。 本课程将为希望提升视频压缩技能的用户提供丰富的知识和实用的工具。
This course is designed for two types of users. If you're new to compression, you will learn how to produce high quality video for distributing over the web, watching on your computer or smart TV/console, for inserting into iBooks or to record onto DVDs and Blu-ray discs. If you know the basics of compression, this course will serve as a valuable reference for questions that inevitably arise when encoding video, like what's the best key frame setting for web video (Lesson 5), what's the best way to work with x264 (Lesson 17) or how do I implement HTML5 (Lessons 31 & 33). All lessons contain video, most integrating both PowerPoint instruction and screencam demos. All lessons longer than ten minutes are annotated so you can quickly find the content most important to you. Most lessons have links to other Internet-based resources. This course has six major sections: Terms and technologies (95 minutes) - provides an overview of codecs and compression, basic encoding configurations (resolution/frame rate/data rate) and then looks at configuration options like bitrate control (VBR, CBR), frame types (I-, B- and P-frames) and container formats. Then it looks at audio encoding parameters (sample rate/channels/data rate), deinterlacing and aspect ratio issues. The section concludes with a look at three free and essential tools, MediaInfo, Bitrate Viewer and MPEG Streamclip. Codecs (52 minutes) - This section walks you through a brief history of codecs used in streaming, DVD and Blu-ray and cameras and intermediate codecs used in editing. Then three lessons introduce you to H.264, with a final lesson on using x264. Encoding Recipes (62 minutes) - These lessons provide specific instruction for those producing video for uploading to UGC/OVP sites, for playing on mobile devices, for local or TV/console playback, for streaming from a web site, burning onto a DVD or Blu-ray disc or inserting into iBooks Author. Encoding Programs (126 minutes) - All encoding programs have idiosyncrasies when it comes to producing streaming video. In these tutorials, for Apple Compressor 4.1, Adobe Media Encoder, Sorenson Squeeze, Telestream Episode and HandBrake, you'll learn these idiosyncrasies and learn to efficiently produce high quality video ideal for your target uses. Distributing Your Web Video (34 minutes) - This section teaches you how to distribute your video over the web. First it outlines your distribution options, including user generated content sites, online video platforms or from your own website via HTML5. Then it provides focused tutorials that show you how to distribute with all three options. Optimizing Your Source Videos (68 minutes) - You can't have high quality streaming video without high quality video. In these lessons, you'll learn to optimize your source footage in Premiere Pro, FCP 7 & X and to remove noise with the Neat Video filter. Then you'll learn to clean your audio in Audition, FCPX, and iZotope RX3, which produces the best quality of the three. The penultimate lesson discusses audio compression, a technique which can improve the clarity of your encoded audio, and the final lesson shows how to declip audio recorded too loudly.
