Encoding Videos for Online Viewing

Encoding videos for online viewing purposes can be a daunting subject for a lot of us. To make things more confusing you have a multitude of “containers” (Quick time, Flash Video, Windows Media etc.) and a multitude of codecs (Encoders/Decoders) and most containers typically support many if not all codecs. So the choices available in just the combination of containers and codecs alone are huge.

Quality Of Video

The quality of video is primarily governed by the Video Bit rate used during encoding. The eventual file size is also directly proportional to the Video Bit rate used during encoding. The larger the dimensions of the encoded video, the higher the video bit rate needs to be in order to maintain the quality of video.

Encoding Settings for HD Video

If your video is HD we recommend the following:

1. Dimensions 1280x720
2. VBR 2 Pass
3. Video Bit Rate of 3000-3500Kbps
4. Audio Bit Rate of 192-224Kbps

For audio, make sure the source audio’s bit rate is higher than the audio bit rate setting you use. Most MP3 files available online are encoded at a bit rate of 128Kbps and lower. So if your source audio is 128Kbps then use this setting for your audio. In other words the audio bit rate you use during encoding should never be higher than the original. The same goes for video too but the settings mentioned above are well below the original HD source video’s bit rate.
FCP Users: The “best” quality is no good for HD video. So please override the settings and use those mentioned above.
