Free bitrate calculator software for windows

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:
- Calculates the required video bit rate for a target WMV file size
- Supported movie length: 99 hours 59 minutes 59 seconds
- Unlimited file size support under Custom File Size based mode
- Supported Disk Size Based modes: 1/3, 1/2, 1, 2, 3, 4, or 5 disks of 650 MB, 700 MB, 800 MB, 870 MB, 2.60 GB, 3.95 GB or 4.70 GB
- Supported Audio bit rate modes: No Audio, 48 Kbps, 64 Kbps, 96 Kbps, 128 Kbps, 160 Kbps, 224 Kbps, 256 Kbps, 320 Kbps, 384 Kbps, 440 Kbps, 640 Kbps and 768 Kbps
- Percentage Error gives you the ability to increase the target video bit rate from -9% to 9% (this is useful if you keep getting lower/higher file sizes for 2-pass VBR encodes in your PC)
- File > Always On Top

DivXLand Bitrate Calculator is specially designed for calculating audio and video bitrates required for video encoding with specific target file sizes.
Tips
Recommended settings to use for a decent quality encoding are:
- MP3 constant bitrate, at least 112 kbps
- Avoid using video bitrates lower than 750 kbps
If you want to find out the current audio bitrate of a movie, open the Windows Explorer and right-click on your movie. Select Properties. At the second tab you should see the file information, and somewhere there should appear the audio quality. (for example, 128 kbps).
Regarding video resolution sizes, for movies it is recommended to use an horizontal resolution of 640 pixels with the corresponding equivalent of vertical pixels.

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.
