Free bitrate software for windows

Bitrate Finder is a software that helps you to find movie bitrate.
Bitrate Finder calculates the required video bit rate for a target DivX/WMV file size.

MP3 Bitrate Changer 1.0 is a very flexible and effective tool to change MP3 bit rate with audio result preview and file size estimation.

Major Features:

1. With MP3 Bitrate Changer you can change MP3 bitrate of your songs, so you can easily send MP3 audio to your mobile device, cell phone, or as an E-mail attachment.
2. MP3 Bitrate Changer creates audio preview and file size estimation of future result before actual conversion-bitrate change, so you can listen and determine which combination of sound quality and file size fit your needs.
3. MP3 Bitrate Changer has simple, intuitive interface, you can change MP3 bitrate simple as possible, in few clicks.
4. MP3 Bitrate Changer supports all mp3 bit rates specified in MPEG-1 Layer 3 Standard: 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256 and 320 kbit/s

Calculate the bitrate to use when encoding to VCD, SVCD, DivX, XviD, DVD and lots of other formats. Bincsoft Bitrate Calculator was designed to be is a program that will calculate the bitrate to use when encoding a film.
BBC should be able to calculate the bitrate to use when encoding to VCD, SVCD, DivX, XviD, DVD and lots of other formats.
Basically BBC wants you to input a video length and how large you wish the encoded file should be. BBC will then calculate the bitrate to use so the encoded file will be as large as you specify.
The bitrate has nothing to do with the format you wish to use, nor does it matter what frame size you use. This also applies to the sound. It doesnt matter what format you use, just make sure you use the same quality as specified in BBC.

WM9 Bitrate Calculator is software that calculate video bit rate.
WM9 Bitrate Calculator - calculates the required video bit rate for a target DivX/WMV file size.
Main features:

Video Bitrate Calculator determines the constant bitrate for encoding movies. Just enter the media type, the duration of the movie, and the audio bitrate.
The application will then calculate the constant bitrate needed to fit the movie to the available disk space.
Multiple audio tracks and multiple disks may also be entered into the calculation. The determined bitrate is given in kilobits and bits.

BitCalc is a software that allows you to calculate and change video bitrate.
Yes, there are many bit rate calculators, but may be a couple o things make this one I have made a little more usefull:
Once the video bitrate is given, you can change it (to round it or whatever) and the size of the final file will reflect it.
It Doesnt need any runtime file, is a stand alone exe
Delphi code is included.
Spanish / English interface.
