[Mp4-tech] I frame Metric

[hungary]

Dear experts,
At the encoder side we could be able to specify the interval at which
the I frame should occur.
But how the encoder intelligent when there are chances of I frame which
may occur at some irregular interval.
How the encoder decides the frame to be coded as I frame (On what Metric
Like SAD or MAE)
Like whts the throshold value of SAD to force the encoder to encode the
frame as I frame ?
