Codecs and file format compatibility
Pearl Mini supports the following codecs:
Table 36 Supported video codecs
Value 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 37 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 values
are: 22 kHz, 44 kHz and 48 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. For
analog signals, 44 kHz provides a good quality audio sample.
Web browsers that use Flash (FLV) do not support 48 kHz MP3 audio. When
selecting this encoding, you must use a web browser that supports HTML5 or a
media player to preview your channel.
