HDDVD and BluRay question

[vbtweb]

I been scratching my head over this one

Divx is to DVD as ? is to HD?

lower bitrate h264 encoded video

yeah that question didn't really explain anything. I rip my DVD's to divx, store em on a server, and watch them wherever. Now with the HD/Blu-Ray stuff, I want the same functionality.

Divx rips take me 6-8 gig dvds and store them at 800-900 meg each with an acceptable quality loss.

I keep hearing about mkv and mp4 for blu-ray.

I found this program ( http://www.makemkv.com/ ) and I'm going to try a few ripping the main movie only and see how it turns out.

re-encoding blurary to something more compressed takes LOTS of time (16-24 hrs) per disc.

IMHO its not worth it, TB disks are CHEAP

mkv and mp4 are containers which stores audio/video... Just like in your case (im assuming) avi is a container which stores the divx video

so if you want to re-encode the bluray to something smaller i would look at handbrake, feed it the m2ts file containing the movie, and have it output a mkv (container) that using a lower bitrate to make the movie smaller

you can also look at tsmuxer, eac3to, clownbd, evilpenguins mediashrink and others for the remuxing/reencoding...

MakeMKV does no transcoding. It simply takes the video and audio you choose and puts it into an MKV container without loss in quality.

Technically, the big gain is file size of going from DVD to DIvX/XVid/H264, is that you are going from MPEG2 to a much more efficient MPEG4... But for HD-DVD or Bluray, you are already dealing with efficient encoders, so cutting the size come at the cost of the quality...

You get loss in quality transcoding a DVD no matter how high of a bitrate you use. The filters used to transcode smooth out details that you see. A good example of a movie that doesn't transcode well is Sin City. I didn't realize how much detail I was losing until I watched the original DVD. In the beginning scene there is a lot of detail in the rain coming down that is completely lost by transcoding.
