View Full Version : Compressing Blu-Ray (m2ts) Files [RipBot question]

Hi Guys,

I have a question which I'm hoping someone will be able to answer....

What is the easiest way to take an m2ts file that has been ripped from a blu-ray disc and get it into a manageable size (<10GB), into an MKV container, surround sound intact and with no discernable loss of quality?

So far I have managed to convert an m2ts file using DivX Pro Converter to a 720P DivX file. The file size is just under 4GB and the quality is fantastic but the audio track always seems to be the first one that is on the disc - usually directors commentary or a foriegn language and not the one I want:mad:

Anyone got any ideas?

Cheers,

James

Ripbot is easy to use and can do what you want. See the MPEG4 encoder GUI subforum.

Do not only take m2ts file.
Take whole BluRay content and rip with RipBot264.
So you can keep chapters in mkv file for better seeking.

Hey Guys,

Thanks for the advice - Have installed ripbot264 and successfully converted an m2ts file:)

Next question - Has anyone got optimal settings for 720P (I am watching on a 50" plasma).

Cheers,

James

Indeed :)

Thankfully, x264 has made things quite simple recently with the addition of the profile system.

I frequently use the following settings for encoding HD movies:

--profile high --tune film --preset slower

But that's just me :). Also, I'm not entirely sure how the CLI options I've listed translate over to ripbot264's GUI, but I imagine it allows you to easily select these options, like MeGUI does.

Does RipBot264 generate a qpfile to ensure i frames at the chapter points?

Indeed :)

Even easier than that. --profile high is default. :p

Indeed. The profile system is well thought out!

Don't know, but don't think so.
But imho it isn't necessary.
Most chapters start at a scenechange, and x264 recognizes scenechanges and inserts iframes by default.

Hi Guys,
Thanks for the replies. Ripbot264 seems to be pretty good but I'm having problems with the sound.
The audio track in the resultant mkv file appears to be stereo and not 5.1 AC3 as selected from the Ripbot264 GUI.
Maybe the bit rate of the AC3 track is too high for my amp, but I've encoded at 384kb/s which my amp supports.
Anyone else encountered this?
Cheers,
James

I'm moving this to the encoders forum for help with RipBot.

Did you select copy stream, which is the default? If you did, are you sure the m2ts has a 5.1 track, and are you sure that RipBot actually selected that one and not a stereo track? (That's a toughie I can't help you with, I don't know how to tell ripbot which track to pick, I don't use it much.)
