Rip Blu-ray to lower res format?

Not having an HD projector, I've not bothered yet with a Blu-ray player. Part of the reason is my projector looks best when driven by a PC at it's native resolution.

Now a while ago I stopped buying DVDs, partly because everything I'd have bought would be out on Blu-ray, so I may as well buy that, and also because I have such a backlog to view anyway.

But due to the aforementioned reason, buying Blu-ray would mean something I couldn't really watch, so I was thinking... I have a BD-ROM drive in my PC, maybe I can buy the Blu-ray version, then rip it to a resolution that looks great on my projector.

So, has anyone (inevitable spammers who will resurrect this thread in 5 months time aside) got much experience with ripping blu-ray discs? What software do I need?

Ideally I need to specify the output resolution, and if I can apply a few ffdshow filters along the way that would be even better.

I'm looking in to this at the moment, but the reasons are slightly different.

I ripped my entire DVD collection to the NAS box a while back, but have since then bought BD.
I now also want to rip those myself and save 720p versions to the NAS (saving 1080p for only the most worthy ones Winking).

I'm looking at getting the Samsung 406AB external drive for it, then using Handbrake on the Mac (after ripping them with MakeMKV)

However, I would imagine that it will take a LONG time to encode it, even on my quad core SandyBridge i7 (2Ghz).

Ogster knows a lot about MKV's, but I'm not sure if he has actually ripped them from BD's. Maybe worth a pm?

I don't think it's the ripping that's the issue here (legalities aside..) but the conversion/downscaling.  Without a doubt, mkv is the format you would want.

Rob, i sent you a pm.

Tbh,  ripping/converting etc is a pain to do on a regular basis,  however, if i have to convert a file, say from Hi-Def MKV to a lower def format, i've found the AVS software to be quite fast on my mac mini & Ion Z-Box, (i think they take advantage of the gfx hardware as well as the CPU)

hope this helps.

I've read various articles that suggest the quality of GPU transcodes isn't as good as the equivalent CPU ones (dropped or blurring of frames).
As far as I know, GPU transcoding doesn't offer the possibility of multiple passes, which is probably why there are quality issues.

I guess maybe with a CPU+GPU encode the CPU takes care of the first pass (faster) and then the GPU handles the second pass...perhaps.

Which piece of software do you mean Ogs? (various things come up when I look for AVS video conversion)

currently using the AVS video converter & the AVS audio converter (for creating M4B audiobooks)  tho, they are both "paid for" products Winking

Oh wow, launched XMedia Recode, saw there was a newer version, downloaded that and where it used to say DVD it now says DVD/Blu-ray. Going to give this a go with that.

Interested to hear the results Rob.

Especially the movie used (length), codecs (audio & video), resolution used & bitrates, one or two pass & the length of time the transcoding takes.

Cheers!

Forgive my stupidity, but if you have a BD-Rom drive in your PC and you're using said PC to drive the projector, why do you need to convert? Surely you can just output at whatever resolution your projector requires and the PC will scale the video. Does it not do a decent job? Transcoding seems like a lengthy process to go through. I tried to make an AVCHD DVD-R out of a 1080i HDTV recording of Fright Night 2 the other day and it took 10 hours just to transcode a 6.5GB file!

You'll need AnyDVD HD or similar to do anything with the BDs though.
