202 Configuration Files
KeyFrameInterval
This tag defines how often to generate and save keyframes in an FLV file.
Description
Setting this tag to a higher value than the default reduces the number of keyframes added to
the FLV file and thus reduces the file size. Setting a higher value for the interval, however,
reduces the seeking accuracy. The value for this tag is defined in milliseconds. The default
value is 1000.
For example, a 15-second video with a file size of 76 KB is increased only to 89 KB when the
KeyFrameInterval
tag is set to 5000, which is an increase of 13 KB, or 17%. The same video
has a size of 109 KB with the
KeyFrameInterval
tag set to 1000, which is an increase of 33
KB, or 43%.
