What’s the best Bitrate for 720P 1080P 3GP:
Bitrate means bits per second (bit/s or bps) unit, often in conjunction with an SI prefix such as kilo- (kbit/s or kbps), mega- (Mbit/s or Mbps), giga- (Gbit/s or Gbps) or tera- (Tbit/s or Tbps). Note that, unlike many other computer-related units, 1 kbit/s is traditionally defined as 1,000-bit/s, not 1,024-bit/s, etc.
In less formal contexts the abbreviations b/s or bps are often used, though this risks confusion with bytes per second (B/s, Bps). 1 Byte/s (Bps or B/s) corresponds to 8-bit/s (bps or b/s).
In digital multimedia, bitrate often refers to the number of bits used per unit of playback time to represent a continuous medium such as audio or video after source coding (data compression). The encoding bitrate of a multimedia file is the size of a multimedia file in bytes divided by the playback time of the recording (in seconds), multiplied by eight.
For realtime streaming multimedia, the encoding bitrate is the goodput that is required to avoid interrupt:
- 1,000-bit/s rate = 1 kbit/s (one kilobit or one thousand bits per second)
- 1,000,000-bit/s rate = 1 Mbit/s (one megabit or one milMavericks bits per second)
- 1,000,000,000-bit/s rate = 1 Gbit/s (one gigabit or one bilMavericks bits per second)
Binary prefixes have almost never been used for bitrates, although they may occasionally be seen when data rates are expressed in bytes per second (e.g. 1 kByte/s or kBps is sometimes interpreted as 1000 Byte/s, sometimes as 1024 Byte/s). A 1999 IEC standard (IEC 60027-2) specifies different abbreviations for Binary and Decimal (SI) prefixes (e.g. 1 kiB/s = 1024 Byte/s = 8192-bit/s, and 1 MiB/s = 1024 kiB/s), but these are still not very common in the literature, and therefore sometimes it is necessary to seek clarification of the units used in a particular context.  Progress trends
Good Video Bitrate Quality:
- 16 kbit/s – videophone quality (minimum necessary for a consumer-acceptable “talking head” picture using various video compression schemes)
- 128 – 384 kbit/s – business-oriented videoconferencing quality using video compression
- 1.5 Mbit/s max – VCD quality (using MPEG1 compression)
- 3.5 Mbit/s typ – Standard-definition television quality (with bit-rate reduction from MPEG-2 compression)
- 9.8 Mbit/s max – DVD (using MPEG2 compression)
- 8 to 15 Mbit/s typ – HDTV quality (with bit-rate reduction from MPEG-4 AVC compression)
- 19 Mbit/s approximate – HDV 720p (using MPEG2 compression)
- 24 Mbit/s max – AVCHD (using MPEG4 AVC compression)
- 25 Mbit/s approximate – HDV 1080i (using MPEG2 compression)
- 29.4 Mbit/s max – HD DVD
- 40 Mbit/s max – Blu-ray Disc (using MPEG2, AVC or VC-1 compression)
Good MP3 Audio Bitrate Quality:
- 32 kbit/s.
- 96 kbit/s.
- 100-160 kbit/s – Standard Bitrate quality; difference can sometimes be obvious (e.g. lack of low frequency quality and high frequency “swashy” effects.)
- 192 kbit/s is the highest level supported by most MP3 encoders when ripping from a Compact Disc.
- 224-320 kbit/s – VBR to highest MP3 quality.
Other Audio Bitrate Quality:
- 800-bit/s – minimum necessary for recognizable speech (using special-purpose FS-1015 speech codecs.)
- 1400 bit/s – lowest bitrate open-source speech codec Codec2
- 2.15 kbit/s – minimum bitrate available through the open-source Speex codec.
- 8 kbit/s – telephone quality (using speech codecs.)
- 32-500 kbit/s – lossy audio as used in Ogg Vorbis.
- 256 kbit/s – Digital Audio Broadcasting (DAB.) MP2 bit rate required to achieve a high quality signal.
- 400 kbit/s-1,411kbit/s – lossless audio as used in formats such as Free Lossless Audio Codec, WavPack or Monkey’s Audio to compress CD audio.
- 1,411.2 kbit/s – Linear PCM sound format of Compact Disc Digital Audio.
- 5,644.8 kbit/s – DSD (A trademarked implementation of PDM) sound format of Super Audio CD.
