Chapter 8: Encoding
162
Bit rate
— This option selects the target bit rate for the video portion of the encoded file. It is
only available for the Cinepak Mobile video encoding format. Typically, this option should be
set to 240, 320, or 400kbps. Larger values may not play back reliably from external storage
devices, and smaller values may not provide adequate quality.
Audio Formats
— The following audio formats are available.
•
AAC
— (Advanced Audio Compression) Provides the highest quality output and the
smallest file sizes. AAC audio playback requires Kinoma Player 3 EX.
•
ADPCM
— Creates audio that is compatible with most Palm handheld devices, including
all Palm OS 5 handhelds. It is compatible with the same handhelds as the Uncompressed
audio format. ADPCM provides good quality compression. Because the audio is
compressed, it makes greater performance demands during playback than the
Uncompressed audio format, particularly on lower performance devices.
•
Uncompressed
— Applies no audio compression algorithm to the audio placed into the
output file. It is compatible with a wide range of Palm handheld devices.
•
Yamaha ADPCM
— Provides about the same compression ratio and quality as the ADPCM
audio encoding format. The Yamaha ADPCM audio encoding format can be played back on
handheld devices running Palm OS 5. It can also be played on handhelds that contain a
Yamaha audio chip. This includes some Sony CLIÉ Palm OS 4 models and Handspring
handhelds with a Springboard module containing a Yamaha audio chip.
•
CLIÉ Audio
— Is a very high quality audio compression algorithm developed by Sony. It is
supported on some Sony CLIÉ handheld devices. CLIÉ Audio is also supported by the Sony
plug-in Audio Adapter. CLIÉ Audio is not supported on Palm OS 5 based Sony CLIÉ
models.
•
No Audio
— To be used when no audio is to be included in the encoded file.
Note:
The speaker on many Palm handhelds running Palm OS 3 and Palm OS 4 is designed to
play back only alert tones, not digital audio. As a result, audio playback can be quiet or
distorted. This issue has been resolved in most Palm OS 5 based handhelds.
Audio channels
— Controls whether the encoded audio stream contains mono or stereo audio.
The AAC, ADPCM, Uncompressed, and CLIÉ Audio encoding formats support stereo.
Sample rate
— Controls the sample rate at which the audio is encoded. Higher sample rates
generally provide increased quality with better reproduction of high frequency sounds.
However, higher sample rates also have greater storage requirements and require more
processor power during playback.
Bit rate
— Selects the target bit rate of the audio in the encoded file. Larger values provide
increased quality at the expense of increased storage requirements. This option is available only
for the CLIÉ Audio encoding format. CLIÉ Audio is always encoded at 44.1khz.
