Description
H.264
H.264 provides high quality video while using low bandwidth. This is
the default and preferred codec for the Pearl-2 and Pearl Mini.
Motion JPEG (Pearl-2 and Pearl
Mini only)
This codec is suitable for streaming and recording video, however you
get lower quality images and it requires a large amount of bandwidth.
Motion JPEG does not support audio.
Table 42
Supported audio codecs and bitrate guidance
Value
Description
AAC
AAC is comparable to MP3 and may even provide better sound quality at a similar
sample bitrate. Supported sampling bitrate values are: 16, 22, 44 and 48K kHz.
Setting the channel bitrate to match the audio source's bitrate provides the best sound
quality and avoids audio resampling. Most digital signals (HDMI or SDI sources) use 48
kHz. Most digital signals (HDMI or SDI sources) use 48 kHz audio. For analog signals, 44
kHz provides a good quality audio sample.
The maximum bitrate for mono encoding of a 44 kHz signal is 264 kbps. For stereo, 320
kbps is supported. Note that lower bitrates (e.g. 32 kbps) with a 44 kHz signal may result
in distorted audio.
MP3
MP3 provides a common audio format for audio storage. Supported sampling bitrate
