BD5 vs Bluray. explain?

n/m

Posted by Objectivist Seal Hunter on 04-12-2009 09:39 AM:

BD5 is just a Blu-Ray movie made for a DVD+/-R (DVD5). It's a Blu-Ray movie stripped down (i.e. no menus, etc). It's as simple as that, from what I know/understand.

And I believe it can be played on a PS3/Blu-Ray player.

why would you bother with that then?....wouldnt the quality suck?...does the resolution stay the same?...not that it would matter if it became all pixelated

I suspect it's another name for AVCHD recorded on a DVD5. The rez is limited to 720p but is otherwise totally acceptable. For 1080p you need a DVD9. Remember that a regular DVD can hold at least four times the amount of picture information than Hollywood's marketing machine would have you believe. Squeezing a BD movie onto a DVD5 is no different from squeezing a DVD movie onto a CD.

I'm a bit confused about this myself too...not sure how/why it works, but when I convert an x264 720 - not just burn straight and watch on a x264 compatible player - to DVD...the quality is fucking AWESOME! (And it's not even a complicated CCE multi-stage process, a simple one-stage convertxtoDVD (but at best quality).)

I've compared a full quality ISO DVD5 with an equivalent 4.3Gb x264 that I've converted and they're not even close, the colours and resolution on the formerly x264 is far better.

Someone explain why that may be

ive got a few bluray rips here on dvd9, AVCHD that play in my ps3 just fine.

in very simple terms, the movie is ripped from a bluray disk.
no extras, English only audio, no menus.
no shrinking of the movie (dvdShrink style) and whaddya know...

the result fits on a dvd9 keeping the 1080p and what ever audio they ripped

remember in even more simple terms the only difference between dvd, cd, hd-dvd and bluray is capacity.

Quality doesn't lack from what I have seen and rips are beautiful.

I always assumed they were re-encodes on the bd5 and such rips, nice to know they aren't might have to grab a few then (on another note I've been loving x264 stuff since I got my new machine).

Baha -- I've experienced the same thing with conversions to dvdr and was amazed at how nice it was, I'm not sure how studios do dvd/bd transfers from film to answer why that's the case though.

I'm kind of confused as to what you mean? Do you mean taking a .x264 file and convert it to a DVD?

Get one and test it out, you will NOT be disappointed. The Sixth Sense was pretty (as well as MANY others).

Majority of films even on DVD9 will be reencoded, even with the DTS/MasterAudio etc stripped. You're talking 50gb originals dropping down to under 9gb.. dropping foreign audio (not often on US/UK discs anyway) and extras will help, but most of the time it ain't enough. The bitrates on original discs can be through the roof.

Comparing BD5 with BD50 is like comparing XviD with DVD9. Sure, you lose a lot of picture information. Whether that information matters depends on a lot of factors such as your own sensitivity to loss of picture information and the kind of system you're watching it on.

I've had XviDs which I couldn't tell from a retail DVD and I've had XviDs which I couldn't bear to watch.

The first HD sample I ever downloaded was Casino Royale. I was absolutely staggered by the improvement in encoding quality that has taken place since then when I downloaded a sample of Quantum of Solace.

Yep, I back-up to DVD and figured rather than just discarding the x264 (which I grab to watch on my monitor) and grabbing the DVDR to retain I'd try a conversion just to see how it came out. Came out beautiful, so tried again. Beautiful again. And then started grabbing a few of the DVD5 equivalents just to compare...and in each and every case the x264 conversion is crisper, sharper and the colours are 'warmer'.

In a couple of cases the original DVD releases are DVD5...and the x264 that I converted to DVD5 is still better!

tsMuxer now has separate settings for creating "Blu-Ray" and "AVCHD" folders. Before it was just the one "Blu-Ray". If you choose the "AVCHD" option tsMuxer won't create a "certificates" folder which could hinder playback on some machines.

I am guessing that is now the difference between BD5/BD9 and AVCHD uploads?

Posted by djpecker on 04-15-2009 09:34 PM:

Its all about source when it comes to encoding. Allways has been. Blu-ray is the best source around at the moment.

Remember its not about resolution, but the bitrate. Bitrate = Quality.

How long does it take to convert a .x264 to DVD? What program you using?

I purchased the Harry Potter 5 DVD a long while ago and the encode was garbage, the HDrip I had was beautiful.

What program and what type of settings, and how long does it take?

As long as it takes it comes down to your processor and memory.

You convert the mkv to vobs etc, i think you can use ConvertXtoDVD not 100% because i never bothered with it, but for me it's a waste of time and easier to leave on the hdd and watch through the pc, specially when in the near future there will be complete releases of them out
Ps this is the wrong forum for this chit chat, try reading the correct sub forum and search out on google

Convversion, burning etc

On my 2.53ghz core2, 4gb ram setup a typical 720 rip takes about an hour or so to convert to dvd using devede
