You need to download a Bitrate converter.
You need to re-encode your video with the changed bitrate.
1.Find the Fourier Transform of the pulse used to transmit data over the channel. 2.Determine the bitrate of the signal by the modulation format (QPSK for example has 2bits/symbol so 1 symbol per second would equate to 2 bits/s) 3.The first null in the Fourier transform is the required bandwidth (~0.75 x bitrate in optical communications, depends on channel) 4. Divide bits/s by the required bandwidth to find the spectral efficiency.
You cannot meaningfully increase the bit rate after having reduced it. Information which has been discarded cannot simply be created from thin air.
Bluetooth 2.0 Nominal bitrate is 3.0Mbps but the practical bitrate is 2.1Mbps
The bitrate in an MP3 file refers to the amount of data used to encode the audio. A higher bitrate typically results in better audio quality, regardless of the volume level. However, a higher bitrate file will also consume more storage space.
A MP3 file is actually a compressed WAV file. The compression is: WAV file size / MP3 file size Bitrate is the amount of kBits a mp3 file uses in 1 second. So a 320kB/s file uses 320kBit in 1 second(or 40kBytes/s) The relation is that if the bitrate gets bigger, the compression get's lower.
FASM "Quality Enhancer Bitrate Squeezer" is an application for compressing h264 video streams, optimised for low bitrate.
Noteburner MP3 Bitrate Converter is a commercial program that can change the bitrate while maintaining the ID3 tags which contain the artist and other information.

It shouldn't. However, it mainly depends on where you get your songs from. Songs at 128 bitrate could sound great (most likely when legally downloaded) in comparison to songs at 192 (most likely when illegally downloaded) possibly because they were converted from a lower bitrate.
