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:

  1. Have an EcoViz watermark
  2. Have, at a minimum, a simple credits page (usually at the end) with small white font on black background, listing:
    1. Link to [1]
    2. List of authors of:
      1. The visualization itself
      2. The current Tarsier software development team (in cases where Tarsier software was used)
      3. Any models used
      4. Any data sources requiring a citation
      5. Any funding sources / grant numbers requiring a citation
  3. Conform to a standard EcoViz Video Format listed below

Exceptions:

  1. 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

Video Formats

Aspect ratio Codec Extension Compliance Delivery Size Frame rate Data rate Bandwidth EcoViz use Cleaner std Tarsier std
16:9 MPEG-4 MP4 NTSC Streaming 192x108 29.97 fps 32 kpbs-V 56k modem Web thumbnail Yes
16:9 MPEG-4 MP4 NTSC Streaming 192x108 29.97 fps 194 kpbs-V 256k DSL Web thumbnail No  ?
  • 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.
