Formatting video for local playback

Mobile phones have limited audio amplification power, so it is useful to make the audio stream as loud as possible, without compressing dynamic range. This can be done through a technique known as peak normalisation, which will increase the volume of the entire audio stream until the loudest moment is at the absolute maximum volume. Most audio editing software contains this feature, and other tools are also available to achieve it.

You may desire to create a single version of your multimedia video that is compatible with all current Sony Ericsson phones listed in this document, whilst retaining the best quality possible. You can use the table in "Recommended video and audio stream parameters" on page 12 to determine optimal parameters for this, which indicates QVGA capable phones will also play QCIF resolution video streams.

Tutorial

This section shows an example of how to format a multimedia video to the optimal quality for phones supporting the QCIF (176x144) visual resolution. The source multimedia video SEexample.avi is included in the archive with this document. The source media is of different resolution and aspect ratio in order to address the issues of correcting them within this example.

Note: Please consult the relevant licenses for any software before using it for commercial and/or personal purposes.

Software

Required software

The following software is needed to complete this tutorial:

• Microsoft® Windows® 2000 or Microsoft® Windows® XP \- as operating system. Make sure the latest service pack is installed.

•Sony Vegas™ 6.0 \- to illustrate resizing video pixel resolution, normalising audio stream volume, as well as altering video aspect ratio and frame rate.

•Apple Quicktime Pro 7.0 \- to encode both MPEG-4 and AAC data streams, and multiplexing these streams into an MP4 IsoMedia container suitable for phone playback.

Other usable software

•Video editing \- the video editing steps are easily translated to other commercial video composition software such as Adobe Premiere™ and Adobe After Effects™.

•Audio normalisation and encoding \- can be achieved with audio software such as Adobe Audition™, Nero SoundTrax, and many others.

•Data stream encoding \- can be alternatively achieved by external encoders such as the XviD MPEG-4 encoder and Nero AAC encoder. Separate IsoMedia container authoring software such as GPAC Mp4box can be used to place streams inside an MP4 container.

•Other software \- other software such as Apple's Final Cut Studio can accomplish all processes involved within a single application.
