Video Delivery
From CCoWS Wiki
This page is intended to list the protocol and standard video formats to be used for delivery of EcoViz visualization products.
Protocol
Videos for general distribution to web and collaborators should:
- Have an EcoViz watermark
- Have, at a minimum, a simple credits page (usually at the end) with small white font on black background, listing:
- Conform to a standard EcoViz Video Format listed below
Exceptions:
- A separate version without either a watermark or credits may be produced solely for inclusion into video editing pipelines where equivalent attribution will be added later. In such cases, a watermarked and credited version should still be produced for use on the web and in independent presentations

- kbps-V: The data rates above usually apply to video without audio. When the audio track is not used, standard data rates suggested by Cleaner XL will less than the what is implied by the nominal bandwidth. Cleaner Xl appears to add about 15% extra bandwidth for the audio, and 10% again, probably just for headroom.
