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:
 
What are encodeing the audio / video into? what is your bit rate?

I re encode mine to h264 video at 4000 bitrate and AAC audio but only at 720 resolution. Have to turn loads of stuff off though so they work with the apple tv but the quality is pretty good.


Edit// forgot to say I put mine in an mp4 container
 
I don't mess about with any settings. I just leave ripbot264 to do it's thing. :)

Yes the H.264 codec is pretty high quality yet nice on filesize.

It's no different to how XviD/DiVX is compared to the original DVD counterpart.
 
would you notice a video quality difference on a 50" tv? Im putting all my blu-rays onto my pc to share across to a A.c.ryan mini and was wondering what to use. I've got Makemkv but not quite sure if I can get more from video/audio quality
 
MKV's are generally pretty good, its difficult to tell any difference between it and bluray tbh.

i also found that DVDFab is much quicker at encoding a bluray as it can make use of CUDA, so most of the encoding gets done on my GTX480

So that mean's you can fit a blu-ray quality film on a dual layer dvd?why didn't anyone think to use mkv on dvd's or is mkv a new technology released after blu-ray and hd-dvd came out?
 
MKV is just a container, it has been around for ages.

You can't simply put one on a DVD and have a bluray or dvd player play them, this will not work.
 
Using DVDfab 8 I can rip a Bluray to MKV in about 30 minutes using single pass.

I rip them to 1280x720 with a constant bitrate of 5000Kbps and remove the HD audio which usually results in a filesize of between 4.5 - 5.0G.

They are stored on my HTPC and output to a 42" Panny plasma and look fantastic.
 
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.

I'll have a proper go with ripbot then. I dont mind waiting as long as I can get as much quality out of it as I can, and 8gb sounds about right for the size and quality im looking for. :cool:
 
Does anyone know how to do things like Avatar and District 9 where you would only need subs for the alien sections? All I seem to be able to do is ALL subs or no subs

technically could you not go through the sub file and delete all the text exept for when the alien language is going? if you see what i mean? no idea if that would work but an idea that just came to me :)
 
I rip my Blu-Rays to .MKV without re-encoding, they're stored on my media-PC. With storage as cheap as it is I see no reason to re-encode except to improve compatibility.
