VideoRequest.Offset Property (Bing, Version 2.x)
Specifies the offset requested, from zero, for the starting point of the result set to be returned for this VideoRequest.
The offset specifies the requested position in the result set for the response that is returned for this source.
Offset is typically used in conjunction with the Count property on the SourceRequest object, and the Total property on the VideoResponse object, to facilitate paging through long lists of results.
The default value for Offset is 0 (zero), and the maximum offset value is 1,000. If a value greater than 1,000 is specified, the Bing Video Service returns an error.
