• MPEG4–3G2: This setting will create an H.263 stream stored in a 3G2 container.
• MPEG4–3GP: 3GP is a multimedia container format defined by the Third Generation Partnership
Project (3GPP) for use on 3G mobile phones. It stores video streams such as MPEG-4 or H.264 and
audio streams such as AMR or AAC. This setting will create an H.263 stream stored in a 3GPP
container. There are two defined standards for this format:
–
3GPP for GSM based mobile phones
–
3GPP2 for CDMA based mobile phones
• H263–MP4: MPEG-4, Part 2, or H.263, is designed for situations where low bit rate and low
resolution are mandated by other conditions of the applications, like network bandwidth or device
size. Examples of video applications for H.263 are cell phones, some low end video conferencing
systems, and surveillance systems. H.263 is important for legacy handheld devices that do not
support H.264.
Note By default, the encoder’s H.263 uses Simple Profile unless you select the Enable B Frames
option. If B frames are enabled, then the resulting stream will be Advanced Simple Profile.
• H263–3G2: This setting will create an H.263 stream stored in a 3G2 container.
• H263–3GP: This setting will create an H.263 stream stored in a 3GPP container.
Note The Encoder Quality setting is currently not active and will not affect the results of the encoding stream
or file.
Note Some players, such as Quicktime
®
player, are not compatible with streams that include B frames. If your
resulting stream has quality issues on playback, try disabling B frames to ensure compatibility with most
players.
