Encode BD50 to BD25

[Nico8583]

Hello,

I would like to encode my originals BluRay to BD25.

I would like to keep only movie with 1 language and 1 subtitle and get the best quality for that. I don't care about time to encode.

I think to use the software BD Rebuilder (if someone has made ​​a comparison with DVDFab HD or any other software better I'm interested;) )

Could someone advise me on appropriate settings for this type of encoding? Automatic or manual settings? Optional High-Speed ​​(BD25) option ? 1 or 2 passes?

Thank you and sorry for my bad english :p

Hi!

1) Use of the subjective "best" is frowned upon at the Doom9 forums

2) My personal choice is BD Rebuilder

Thank you

You're right, I transform my topic:)

simple answer:
Use Ripbot264 or similar GUI for x264.
Stay away from transcoding via DVDFab (lower quality than x264)

more complex:
to get a given size of output (BD25) you need 2pass.
to keep menues, you have to use BD Rebuilder, but for only Mainmovie and 1 audio and some subtitles Ripbot is enough.
RipBot has BluRay and AVCHD profiles
Ripbot uses x264, one of the best (the best?!) H264-Encoder

Thanks for your feedback, I have already used RipBot in the past and I didn't like the GUI. I'll try again ;)
Another feedback ?

RipBot can't create a bluray structure or i don't found it :confused:

In my experience, when ripping from a BD50 to a BD25, a typical movie will fit onto a BD25 without actually re-encoding the video at all. I'd say the max video size I typically see is 20GB. If you're limiting yourself to one audio track (I stick with AC3 640kbps, and on a rare occasion will use DTS 1.5mbps), you should almost always have enough space on a BD25 to completely avoid having to spend hours re-encoding.

All you need to do is rip the original BD, demux the video and chosen audio stream from the disc with TSMuxer. Usually with blu-ray the audio streams are DTS-MA or Dolby TrueHD sometimes. Take the HD audio stream, run it through EAC3to to convert the HD audio to DTS or AC3.

Then use TSMuxer to mux the video and audio back into BD file structure. Burn everything using IMGBurn and you're ready to rock.

good tips

To me, the lossless audio isn't worth the space. AC3 @ 640kbps sounds pretty damn good. Some people argue that DTS at 1.5mbps is better. I can't tell much difference besides volume levels and the sound is more "sharp" with DTS. So, even if it's better, it's not 2.3 times better!

On that same note, DTS-MA and Dolby TrueHD DEFINITELY aren't worth the space waste on my BD-25s. If you stick with DTS or AC3, you're not going to have many issues with movie only without re-encoding video to a BD-25.

Also consider that re-encoding causes a big hit in quality versus not reencoding. So if you have to re-encode the entire video just to save a couple of GBs, it's DEFINITELY NOT worth saving the master audio tracks.

Yeah.Do exactly this all the time.Most Movie only will fit onto a single BD-R and they are cheap enough now if you have to split to 2 Disks (not often).
As we should all know Picture is Primary,and AC3 is plenty good enough.Never been a sound nut.
And of course it is so,so much quicker.

Although simply as a matter of interest given faster processors than mine (Pentium 4 3.4 Ghz Dual Core) how long would it take now to re-encode using BD Re-Builder down to a BD-9 or say a 29GB movie to BD-25.

A desktop Core i7 >3.0gHz with 4 cores (8 threads) is going to take somewhere between say 2.5 - 24 hours depending on factors like length of the movie, how fast your drives are, if you're doing a movie only recompression, whether you're doing 2 pass, 1 pass (CRF), etc.

Many thanks for the reply.Goodness even after 2 years (the last time I checked on re-encoding speed) it would still take that long.To be honest I am surprised. I thought that perhaps a movie only compression to DVD 9 or BD 25 would be an hour or less by now.The computer industry needs to come up with some form of new processor power if it's not to come to a grinding halt (A breakdown in Moore's law).
Now I know many aren't to fussed about time scales with this sort of thing,but unforunately I am not one of them.Leaving a computer on all night is a real waste of energy and a form of inefficiency in my book.Yes I am also impatient I suppose.

Pity I do actually like the notion of puttig a feature length Blu-ray movie at 720p re-encoded to AVCHD using BD Re-Builder or Ripbot264 on a DVD 9.It would give me a nice sense of economy and satisfaction.Who knows,maybe I won't have to wait to long before I can do it in that sort of acceptable time scale.

Thanks again for the update.
