Getting Blu Ray Rips Smaller at Source

[jamd1]

I just noticed after ripping Beowulf Blu ray using AnyDVD HD - Firstly I Aborted the rip after a few minutes and kept the partial .m2ts file. It was 700mb large and it played perfectly in power dvd for 12 minutes. Now using simple arithmetic 10x12 = 120 minutes . The movie is less than 2 hours long so the whole movie should be on a file less than 10x 700mb = 7gb . However the full rip comes to around 30gb. Has anyone else noticed this and is there a potential here for making much smaller rip files?

Ever considered the video track is encoded with a variable bitrate?

This would account for the difference in calculated size, if it were constant bitrate your calculations maybe correct, i don't know anything about BlueRay at this point but i do know that HDDVD's often include 2 video tracks, Transformers for instance:
3: h264/AVC, 1080p24 /1.001 (16:9)
4: VC-1, 480p30 /1.001 (3:2), -84ms

You may have been ripping only the 480p track..... if BlueRay's are the same that is.

You can try AVGo Media Recorder to backup your Blu-Ray. This free software can backup blu-ray disc into various video formats, and you can customize the output setting, e.g. video bitrate, framerate, resolution and so on. So you can control the output file size. :)
