5.4.4 Natural Video
Choosing Natural Video will enable 60 fields* per second true interlaced picture for high motion
video. The use of Natural Video requires the H.263+ and H.263++ video protocols. Natural video
will be disabled in H.323 MultiSite calls and in H.320 Continuous Presence MultiSite calls.
Auto
When set to ‘Auto’, the MXP will prefer the H.264 400p/448p resolutions from call
speeds between 384kbps and 1920kbps.
For calls above 1920kbps, iSIF/iCIF video will then be preferred.
However, if Natural Video is forced to a specific call rate (e.g. 768kbps), iCIF/iSIF
will be preferred on all calls that match or exceed that call rate.
When connecting to systems that do not support the new H.264 resolutions,
Natural Video will perform as it did in previous versions.
Off
Natural Video Off will disable both transmission and reception of Natural Video.
Custom
384 kbps and above to 1920 kbps and above.
* 50 fields per second on PAL systems.
