Some embodiments provide a method for adjusting a video sampling rate during an video encoding operation. The method receives a metric that quantifies the usage of a computer that performs the video encoding operation. The method computes an adjustment factor based on the metric. In some embodiments the metric is a system idle time. The method defines the video sampling rate based on the adjustment factor. Some embodiments compute the adjustment factor by performing a non-linear operation based on the metric. In some embodiments, the non-linear operation includes performing an integral operation based on the metric. In some embodiments, the non-linear operation includes performing a derivative operation based on the metric. Some embodiments perform more than one operation to compute the adjustment factor. In some embodiments, each operation is assigned a weight.
