或许你会习惯用优酷那种模糊了双眼的视频能够满足你好奇的心，或许你沉醉在这样的快捷中，安逸！时代发展，我们的网络互联也在进步，光纤已经密密麻麻铺满了整个土地，网络可能已经是一个简单的话题，我们的硬件在提升，我们的精神享受也伴随着时代的进步而迅速提高，为何不选择更加清晰的视频呢？

我只能说这不是梦，我们会由衷得感谢我们华裔科学家发明了光纤，得感谢奋斗在网络互联的每个运行商，虽然他们的行为近乎霸道。得感谢Adobe公司兢兢业业，得感谢为提高视频质量而不断研究的科学者们，虽然他们一直被人当成异类！甚至我们得感谢能让我们看到视频的每一台服务器。我相信我们能做到！

以下是一些视频参数~

Codec
Choose H.264 for the video codec. Choose AAC for the audio codec.

Frame rate
This is usually 29.97 for USA/Japan/Canada, while in Europe and rest of the world it's usually 25. If there is an option that says "current" just go with that. Please note that Vimeo converts all HD videos only up to 25 frames per second in order to optimize playback performance.

Keyframes
Every 30 frames. This is basically how often the compressor references your uncompressed video.

Data rate
1800 kbits/sec for standard definition 4:3 video , 2500 kbits/sec for widescreen DV, or 5000 kbits/sec for high definition. Making these numbers higher will increase both quality and size.

Size
640×480 for standard definition 4:3 video, 872×480 for widescreen DV, or 1280×720 for high definition. It is also best to export 1920×1080 or 1440×1080 video as 1280×720 too.

Deinterlace
Yes. If you do not deinterlace, you will often get weird-looking horizontal lines in your video.

Sound sample rate
44.100 kHz

Audio quality
You want audio with a bit rate of 128 kbps. You can set your audio to really good quality without increasing file size too much.
