Comments on: HowTo: Encode a Blu-ray rip into a smaller format without losing quality

So… I think I got a little off topic here, but I thought I would reply back in case someone doing what I did had the same troubles I experienced. I had originally tried the script you wrote in another topic to rip my discs to m2ts files, but the keys didn’t work on because discs were to new. So I am using makemkv to get the movie off the disc, then I ran your script on the mkv file to do the compression. On one movie, the subs got burned into the video somehow and wouldn’t go away. Adding the -nosub flag and rerunning the script fixed the issue. Anyway, this post was a big help!

I’m going to try to redo it and add these flags. I’ll let you know how it works

That means the subtitles are part of the original video itself – they are not overlaid. All the tools used in this article do not do anything with subtitles.

Hey,
I just ran the script on a blu ray I wanted a back up of, and the .x264 file seems to have the subtitles permanently burned into it, i.e. I can’t turn them off, not even in VLC in the advanced settings. Is there any way get them out of the video, or to re-rip and make sure they won’t show up again?

It’s still in draft and I got distracted by other things. Will have to get around to finishing it one day.

“I’m actually in the final stages of putting the finishing touches on a new tutorial for ripping and preserving DTS tracks and using a slightly modified method of composing MKV’s using MKVMerge without needing to put them into an MP4 container since MP4Box doesn’t seem to like every converted stream out there. The results are greater success in dealing with multi-part movies, securing the right language track and ensuring the frame rate matches properly.

Stay tuned!”

Did you ever finish this? If so, could you point me to it?

Thanks for the great script!

Hi!

Thanks for your nice script..

I hacked it a little bit, becouse I had no space to copy the file to a writeable folder.

woth my version you can give the full file as input and optionally a folder for output.

Hi,

I found the options =>
b_pyramid=none, b_pyramid=strict and
b_pyramid=normal

I used “normal” and it worked.

Thanks for the help.

The version of MEncoder supplied with Ubuntu Lucid has had some of its parameters changed, and this is why your encode is failing. The “b_pyramid” parameter no longer accepts the argument used in the script and needs to be changed (b_pyramid now has options!). Check MEncoder’s man page for the possible arguments to use here and substitute accordingly, eg: b_pyramid=option.

I’ll make a note about it in the article later.

I tried your script on Ubuntu 10.04, it did work very well in 9.10 – but it looks like 10.04 broke the script.
