Recommended audio codecs, bitrates, and parameters
The table below shows suggested values when encoding video and audio streams for local playback on Sony
Ericsson phonesThe basic video parameters will offer basic quality upon playback. Conversely the optimal
parameters will give truly excellent quality on Sony Ericsson phones, with fluid motion, rich details, and minimal
compression artefacts.

Basic audio parameters produce acceptable audio quality, while the optimal parameters significantly reduce any
perceptible audio compression artefacts. Increasing parameters beyond the optimum values is possible with
successful results, but it may introduce pauses and other unwanted errors when the media content is played on the
target phone. As such it is not recommended, unless you can invest the time to verify successful playback on the
target phones for each individual multimedia video.
