| Microsoft DirectX 9.0 |
The SetOutputFPS method sets the uncompressed output frame rate for this group.
Syntax
HRESULT SetOutputFPS(
double FPS
);
Parameters
FPS
Output frame rate for this group, in frames per second. The value cannot equal zero, and cannot have more than seven digits after the decimal place.
Return Value
Returns S_OK if successful, or E_INVALIDARG otherwise.
Remarks
Rendered output from this group runs at the specified frame rate, and all edits on the source material are rounded to the nearest frame boundary, as defined by the frame rate. For best performance, use the same frame rate for all groups, video and audio.
The IAMTimelineGroup::SetSmartRecompressFormat method overwrites the frame rate.
Requirements
Header: Include Qedit.h. This header file is not compatible with Microsoft® Direct3D® headers later than version 7.
