Just experimenting with a few of my original Blu Rays discs.

Using RipBot264 to convert my Blu Rays to MKV. It takes upwards of 7 hours on an average Blu Ray but I'm shocked how high the MKV quality is.

A 45GB Blu Ray is now an 8GB MKV. I can't notice much/any difference albeit on a 22" 1080p screen.

We are allowed to talk about this aren't we? :confused:
 
I don't mess about with any settings. I just leave ripbot264 to do it's thing. :)

I'd be looking to rip them to full 1080p if i can, and keep hd audio. What program would you recommend for that? I see makemkv does everything for you, and im looking into Ripbot264

Ripbot264 does a real decent job if you don't mind waiting.

I've done 3 blu ray's so far.

A 2hr 40m one is around 8GB, a 1h 40m one is 3GB and a 1h 35m one is 6GB.

I don't know what ripbot264 did to the 1h 40m blu ray for it to only be 3GB. I've watched it and it's superb quality. These are all in 1080p and with their original audio.
 
Just tried DVDFab with Avatar blu ray.

Although it took only 30 minute, the MKV file turned out to be 37GB from an initial 46GB. Not really worth it really.

Also had problems with crashing and it also seemed to give my mobile broadband a few problems. It's now uninstalled. I already have Handbrake and RipBot264 installed.

I also have the problem with no subtitles on Avatar and District 9 MKV's. I presumed they were 'burnt in' to the picture already.

Can someone help, i am a bit confused with using ripbot.

I have ripped my blu ray to Hard drive then select the file i want to load into ripbot (which is around 26GB)

Changed the mode so it does 2 pass and left everything else at default apart from using the original DTS audio. 4 and a half ours later it was complete but i have no file :mad: and have no drive space missing so guess i done something wrong.

Any tips?

In RipBot, what do you have as your 'output' setting? ie. Where your ripped file is being saved.
