 +===== On demand and simulated live multirate streaming for desktop and mobile =====
 +
 +Multirate streaming provides the best results for simulated live and on demand videos. ​ You provide a master or near master quality file which we then re-encode into multiple formats. ​ This is triggered automatically when you upload any file with a bit rate of 2500k or higher. ​ Although we accept almost any format for this, we recommend the following:
 +
 +| File Format | MP4 / MOV |
 +| Video Codec| h.264 Main or High Profile |
 +| Video Resolution and Rate | 1280x720 @ 5000k or 1920x1080 @ 8000k |
 +| Audio Codec | AAC |
 +| Audio Channels and Rate | 128k mono or 256k stereo |
 +| Est File Size | 3GB/hr |
