Video Encoding Recommendations
For best results and optimal web playback, Simian recommends the following settings for encoding videos for the web.
To ensure the best possible quality of compression, begin with the highest resolution source files available.
For optimal playback, browser and platform compatibility, Simian recommends H.264 video codec, with a AAC audio codec in MP4 format.
Fast Start: Enabled
Fast Start is required and necessary for videos to begin playing instantly, vs. progressive download.
NOTE: If encoding to MP4, since most encoders automatically enable fast start on MP4 files, the option may be greyed out or un-selectable.
Bit Rate: The higher the resolution, the higher the bit rate required in order to maintain quality. Below is a handy table of Simian recommendations by resolution.
Note: Higher bit rates may not stream well on weaker internet connections.
|Video Resolution||Bit Rate||Optimal File Size (30 sec)|
|426x240 pixels||300-700 Kbps||100KB-1 MB|
|640x360 pixels||1500-2500 Kbps||3-5 MB|
|854x480 pixels||1500-2500 Kbps||5-6 MB|
|1280x 720 pixels||2200-3500 Kbps||10-13 MB|
|1920x1080 pixels||3000-5000 Kbps||13-17 MB|
Bit Rate Threshold Warnings: Simian scans every video uploaded and displays a warning if the bit rate exceeds the default threshold setting of 3500 KB. A secondary warning will display if the Fast Start is disabled. Bit Rate Threshold settings can be found in Account Info.
Real Time Video Encoder: For users that are unfamiliar with the encoding process or don’t have an encoding application, Simian's RTVE App does the work for you.
