The GetDefaultEffectB method retrieves the default effect. This method is equivalent to IAMTimeline::GetDefaultEffect, but receives a BSTR value rather than a GUID.
HRESULT GetDefaultEffectB( BSTR *pGuid );
[out, retval] Pointer to a variable that receives a BSTR value representing the GUID of the default effect.
Returns S_OK if successful. Otherwise, returns E_OUTOFMEMORY or another HRESULT value indicating the cause of the error.
The method allocates memory for the string. The application must call SysFreeString to free the memory.
