Question about handbrake and blu ray rips

[thetruth1985]

Hello. I normally rip my dvd collection via handbrake and the resulting file is usually between 1 to 2 gb. All I do is use the ATV2 preset and set the rf value to 19.25. The original dvd files are usually around 5gb before I rip them. Yesterday, I had a blu ray rip that was 720p and the file size was 2.5gb when converted to avi. When I ripped it for the atv2 using my normal routine, the file was almost 4gb. It plays fine on the atv2 but is there anyway that I can get the file size to be less than the original rip? I'm guessing there is something I am missing in handbrake. Thanks to anyone who can help.

Yes, turn up the RF.

4GB is the output that handbrake would give if you were encoding from the bluray itself, but it treats the avi the same way. The bitrate on the AVI is really lower than it 'should' be, the ATV2 preset for your RF value will use a higher resultant average bitrate than the source, resulting in a larger file, increasing the RF will compensate for that.
