Specifies the key-frame rate used for the current video compressor.
Declaration
property VideoCompression_KeyFrameRate: LongInt read GetVideoCompression_KeyFrameRate write SetVideoCompression_KeyFrameRate default DEF_VideoCompression_KeyFrameRate;
__property int VideoCompression_KeyFrameRate=read=GetVideoCompression_KeyFrameRate, write=SetVideoCompression_KeyFrameRate, default=15
Property VideoCompression_KeyFrameRate As Long
Description
Specifies the desired key-frame rate for the current video compressor.
If the value specified is -1, the filter will use the default key-frame rate. If the value is zero, only the first frame will be a key frame. If the value is negative (-1), the filter will use its default key-frame rate.
Use the OnVideoCompressionSettings event to know the default value for the current codec (see the Software compression by using codecs chapter for more explanations).
