How to set output video file size in Handbrake 1.1.1?

Solution 1:

Vidcoder is an alternative front end for Handbrake and offers the target size option. You don't need to install Handbrake separately. http://vidcoder.net/

Here's the target size option:

Solution 2:

HandBrake 0.9.5 (released January 4, 2011) was the last version to support the "target size" feature, hence 1.1.1 does not present such option. You can however compute the final file size using the following formula

File size (kb) = bitrate(kbps) x running time (s)

If you want it in MB just divide the resulted value by 1000.

Solution 3:

The devs have stated publicly that they will not be bringing this feature back (disappointing imo, since there are many valid use cases for it).

One workaround: download this handy calculator app from Christian Wheel, which will give you a value to put in the "Avg Bitrate" field to achieve a certain output size.
