Frame Interpolation
[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
Frame interpolation is the process of creating intermediate video frames based on the data in two consecutive frames of encoded video. In effect, frame interpolation increases the frame rate of encoded video at the time of decoding. You can use frame interpolation to improve the smoothness of playback for video streams with low frame rates.
Because this is a decoding feature, it does not involve any special encoding options and adds no overhead to the content. Frame interpolation is specified as an output setting in the reader object.
Only the Windows Media Video 9 codec supports frame interpolation.
