Trying to fit LOTR trilogy on a single KDVD...
 
... at least that's what I want to try to do.
That means almost 9 hours.
I tried (just a test) with 352x576 MPEG2, non-anamorph, MA script, cutting credits, and in CCE with Q=40. I did a 5% slice, and it would be a final size about 3400 MB. That would be enough with 1 audio track each film, and no subtitles.
Has anyone tried to do this before?.

I put 10h on a DVD but in VCD resolution. Above it doesn't worth the cost. Q=40 ??? Above 30 is barely watchable (even if in 352*576 things can be different than in 704*576). And I don't even speak about the audio : you plan to put it in 2.0 ? What a pity :-)

At 0.5€ (0.60$) the DVD-R, I think I can use 1 DVD per movie :-)

I suggest you try QCCE by Jonny, it includes Q prediction which is very handy.

This spreadsheet I made has been quite useful when putting several movies on one disc. It calculates the average bitrate and required video space depending on the complexity of each movie. This is calculated by encoding a sample (1-3%) of each movie and then determining their average bitrate. After you input the necessary values the sheet will give you the final video size for each movie which you can use in QCCE.

EDIT: You shouldn't worry about the subs, the space they require is extremely small. Please don't tell me you're going to use Spanish audio? :twisted:

I did this with a resolution of 352x480 and an audio of 112. I used calcumatic and Tmpeg author. Nothing special about the avs script. Just blockbuster.

I managed to put fellowship extended along with 2towers extended and return of the king theatrical.

my minimum Cq turned out to be about 52 for 2 towers.

looks great to me.

Oh yeah, I also started it all with the 6min trilogy trailler.

Mr_J 07-06-2004 03:36 PM

I mean, looks great for 10hrs on a dvd, viewed on a 28inch TV.

It's amazingly sad to know how much time Kwag spent to developp a method that allows to put a movie on a CD with a near-DVD quality and see that it is used now to put DVD on a disc with under-VCD quality. :?

Keep the focus ! :-)

Encoder Master 07-06-2004 03:48 PM

Perhaps you should post some samples to show DialHot he's right or not. :wink:
And we all can see how sweet youre results are. :D

Do you think I need samples or do you thing I'm talking about somethings I know and have already tested ?

Take a little time before to answer... ;-)

(but you can also post samples then I'll explain to you why they are awfull and you will have no choice but cry and trash the DVD ;-))

To be more serious : there is no quality "good enought for a 10h ..." blah blah blah. There are good and bad encoding. If they are good, they are good good. But if they are good "for a ..." blah blah blah, then they are bad.
You understand what I mean ?

you got my (sad) feelings Phil, and wrote the words from my mind.

Not so bad dial. :wink:

Actually I mean if the results are so horny he should post some. With this Q value I think your absolutly right. :)

Mr_J 07-07-2004 10:57 AM

why post results? I mean, the method and script is so simple and plain, anyone can try a 1 min sample and see for themselves if it hurts their eyes or not.

Besides, I thought 10 hrs on a DVD was the focus. As advertised on the KVCD homepage.

kev23m 07-07-2004 01:28 PM

I generally do movies which are around 160 mins. I use to try and do it in single cd rips but after some tests i prefer to do them in 2 cd with 480x480 resolution and a cq of 70 & above.
So you can fit in 8 hours with good quality. The idea is to get a dvd backup so compromising on that does not make sense just to fit in more.

These encodes are usually with Min Bitrate = 64 Max = 1800 to 2300
Using kvcd 3- Mpeg2 Template.

digitall.doc 07-07-2004 01:48 PM

Thanx to all for your replays.
Yes, I tested CCE with Q=40 as a minimum reference value. But, as expected, the quality is not very good: little noisy (did I read somewhere in the forums that CCE adds noise?) and with blocks. And I maybe would need to even raise Q to fit 2 audio tracks (yes, one in spanish :oops: , thinking in children, of course :? ). To me, it doesn't worth it.
I maybe could do this in 352x288 and MPEG1 (in Q=40 test, average bitrate was around 800), but I think I'll try to fit just 2 parts in a DVD-R, and mix the third one with some other film in another DVD-R.

Yes but that depend on the sources. And when the sources used give you a CQ=52 then we (generally) do not call that an acceptable quality.

The home page says "up to 10 hours", not "10 hours anytime, anyhow" ;-)

And trust me, you can have 10h on a KDVD with 352*480 and CQ around 70. I already did that.

@Dialhot

don't be so uptight, i read kwag put three normal dvd's on one disc at great quality, so what if he is only going to get vcd quality for a dvd it's the beuty of having a very watchable disc with all movies on one.

I would'n do it, but go for it mate njoy

Name me 3 "normal" movies which total length is 10 hours :-).
3 movies is generally 6 hours, not 10.

With CQ=52 he doesn't have a VCD quality, he has a UNDER VCD quality.

Did you ever try to encode at that CQ in 1/2D1 reso ? That is verry far from a "very watchable" disc. And if you think so, read my first post again : "I thing you really need to learn what is called a good encoding :-).

fozzieb 07-08-2004 08:08 AM

@Dialhot

Damn it your right again, me goes back to being quiet on this board :wink:

Mr_J 07-09-2004 09:39 AM

Just to keep in focus with this topic,

yes, LOTR is 10 hrs.

I encoded this in a very simple fasion at 1/2D1 resolution and had it all fit on 1 dvd.

Althought at CQ 52, it is, in my opinion, well above vcd quality.

You can listen to Dialhot's convictions, or you can try a short clip yourself and as the viewer, you can be the judge. (unless you are planning to give this to Dialhot for his birthday)

Boulder 07-09-2004 10:12 AM

Think of it as a kind of sports, trying to fit as much video per disc as possible with watchable quality. Wasn't Jellygoose testing if he could fit The Two Towers Ext Edition on one CD late last year?
