Test Notes

We are normalizing encoding parameters to the default iPad setting provided by MediaEspresso 6.5. This is the only way for us to ensure uniformity when we compare the transcoding time between applications. In some cases, there is no way for us set equal settings across the board. For example, Badaboom maxes out at with 160 kb/s audio (for the iPad profile). Audio affects the final transcode time to a smaller degree than video, but it nevertheless is one variable.
