We strongly recommend exporting your Source/Master copy as a Quicktime-compatible h.264 file for the best result. We specifically recommend the following settings:
Frame Size: 720 x 480 (1280 x 720 if you have a Pro account and would like an HD version as well)
Video Codec: H.264
Audio Codec: AAC
Video Bitrate: 3.5Mbps - 5.0Mbps
Audio Bitrate: 128 Kbps
Fast Start Enabled: Yes
Newer versions of Quicktime give the option to "Save for Web". When using this option the default setting for "Computer" works great.
Many of our producers use MPEG Streamclip to do their final compression. Here are the settings that we've found work well on blip (checking Multipass will give you a smaller file size with the same great quality, but it will significantly increase the time it takes to encode your video):
If you do not have the ability to export a H.264 Quicktime file we recommend trying to follow these export settings as closely as possible in regards to bitrate, codec, etc. regardless of format. We'll still try our best to transcode your file to be used in our Blip Player and for distribution across the web.
