Boolean
bool
True, if the effect will not modify the input frame; otherwise, false.
Remarks
When IBasicVideoEffect.IsReadOnly is set to true, the system automatically copies the frame data directly from the input frame to the output frame before ProcessFrame is called. This allows an effect that analyzes the input data, but does not modify it, to skip the creation of the output frame data.
