3 Hours+ DVD

[Fozzee]

Hi
I'm creating a DVD from a 3hours 30min source.

I'm using 352 x 576, Pal, Bitrate 2500, Audio 48hz 224.

Is this considered acceptable to create a good video??
I am using Procoder or TMPGEnc.

Cheers

Sounds pretty good, but what's your source? Avi, capture, DVD?


2-pass VBR with a 2500 avg. would be even better.

[tygrus2000]

I wouldnt waste my time trying to put that source to DVD the way you want. First the resolution is way too low for DVD spec and will have to be rendered up and it will immediately pixelate on you.

Most that you can resonably put on DVD blank media is 2 hours, thats at 720x480 resolution, 2500 bit rate. That bare minimum - anything else you might as well put to VCD or SVCD.

[Fozzee]

You say the resolution is too low for DVD spec???
352 x 576 is an official resolution for PAL DVD (known as half DVD).
Why would I want to make a 4 CD SVCD when I can get it all on 1 DVD at more or less the same quality??
Please explain more to back up your comment.

Cheers

My source is 2 CD high quality DivX.
The encode is finshed now and looks great. Just as good as SVCD and fits on 1 DVD

I would go 2675, that's about the max bitrate you can get and still fit.

as far as quality... that's going to be up to you - if you like it, it's good enough...

3 Hours Plus on a DVD-r, No Problem .

Why, cause i've done it

I put the Lord of the rings - fellowship of the ring special extended version on 2 DVD-r, When both parts are joined together it come's to 3 hours 38 mins 42 secs.

Used DVD2SVCD setup for DVD Encoding using CCE 4 Pass VBR, 720x576, 384kbps 48khz 2 Channel Audio, can't remember the birate now but i can tell you that the picture quality is excellent, but thats because i used a DVD as the source.

In your case i would do what ZippyP says, go for a 2 pass VBR in TMPGEnc to get the best quality possible.

So 3 hours+ on a DVD-r can be done. And like you said why waste 4 or 5 CD's doing a SVCD when you can get the same results on DVD-r if not better.

[Fozzee]

So I can keep the resolution at 720 x 576 and still use a low bitrate??

Funnily enough my source is the same film but a divx backup.

I just put 3½ hours on 1 DVD with 352x480 MPEG2, 2600k, AC3, cartoons of course, and it looks fine.

[marvel2020]

Yep your can keep the resolution, and if you want more birate added to the video then Drop the audio down to 192kbps.

DVD players don't really care about the audio birate just as long as it's set at 48khz, but i still wouldn't go below 192kbps.

[andkiich]

You can keep the original resolution, but I think that you'll find at the lower bitrates, the 352 will be a lot more tolerable than 720. Just my opinion, though.

[ZippyP.]

... the resolution is way too low for DVD spec and will have to be rendered up...

Most that you can resonably put on DVD blank media is 2 hours, thats at 720x480 resolution, 2500 bit rate.

Here are the legal Pal DVD resolutions:
720 x 576 pixels MPEG2
704 x 576 pixels MPEG2
352 x 576 pixels MPEG2 (Same as the CVD Standard)
352 x 288 pixels MPEG2
352 x 288 pixels MPEG1 (Same as the VCD Standard)

As for your second statement:

2 hrs = 7200 secs.
7200 secs. X 2500 Kb/s = 2.25 GB of data which is only about 1/2 of a DVD capacity.

[machine head]

I've backed up my 2 led zeppelin dvd's and two other videos of concert footage onto one cd at vcd quality-about six and a half hours on one DVD and it looks and sounds great at normal viewing distance. Irispective of wether the quality is DVD standard, the point is it takes up less space on one disc and can be more convenient. :P

[FOO]

I got away with Shogun on 2 DVDs (barely)
6 episodes of 2 hours = 12 h
x 75% = 9 hrs without commercials.
352 wide instead of 720 helps lots
IVTC gets another 20% off full price.
192 K joint stero also.
2 pass VBR with prefiltering

Thats 4.5 hrs on a DVD.

It looks nearly as good as the TV did, but I don't have a super clear
picture on that channel anyway.

No way I would try to do more than that

[ZippyP.]

So I can keep the resolution at 720 x 576 and still use a low bitrate??

If you did it the way marvel2020 did it.....

...using CCE 4 Pass VBR, 720x576,

In other words, if you use a low average bitrate in VBR.

[Fozzee]

If I use 2 pass VBR with 2600 average what would you suggest as the max bitrate??

[marvel2020]

Fozzee use the Birate calculator from the Tools section on the site.

Anyway i found my post with the Birate i used for my backup on this page 8th down from the top...

The only thing i forgot to add to it was i had to lower the min birate to 1500 for the second DVD.

[Fozzee]

Fozzee use the Birate calculator from the Tools section on the site..

I have ... that doesn't help me calculate the max bitrate on VBR does it?

And Procoder only has average and maximum bitrate settings on VBR.

[ZippyP.]

If I use 2 pass VBR with 2600 average what would you suggest as the max bitrate??

500-2600-5000 should be good.

[marvel2020]

Yep it does

Just use the birate that the calculator gives you as your average and Maximum Birate.

You should set you Minimum birate to around 300 or 500

non-sense! 352X576 at 2500 bitrate will look better that 720X576 at 2500.

I'll throw in my two cents, as I have been here and done this before.

Here is what I did....
I took a 2 hour source.

Encoded it with TMPGENC at CBR 8000 (Best possible quality)

I then took the outputed M2V file and the corresponding audio file into my DVD authoring softwre.

I authored the DVD with menus, etc....

The DVD authoring software then mulitplexed and put all the files ready for burning onto my hard drive.

NOW - I know what you are thinking. That DVD size is bigger then 4.3 GB.(one DVD-r) And you are right. It is bigger. But not for long.

Now go into DVDSHRINK, and use the OPEN FILES option. Open up the files you just authored. Have DVDSHRINK recompress the movie to fit onto one DVD-R !!

And then burn the resulting output to your DVD-R.

Some of you might be thinking about the how double compression thing....
Well that can be a problem. It all depends on many things. Most importantly, you have to start with a good quailty source.
And since we compressed with the best possible quailty in TMPGENC the recompress in DVDSHRINK will still look good.

Since you are using a 3.5 hour source you could lower the bitrate some, but don't worry about TMPGenc trying to make it fit onto the disc. Try VBR with MAX rate 8000. If it goes over then whatever...... go for good quailty. Then have DVDSHRINK compress it lower.
Give it a try.

[lordsmurf]

I've heard about that DVD Shrink method. And I've used it.

I'd consider that more of an "oops" method. When you screw up, use DVD2one to wipe up the mess you made. I don't really like DVD Shrink to be honest, as it macroblocks a lot.

It's really better to just do it right the first time.

I've done that method before when I get episode discs that only have 3-4 episodes on a disc. To me, that's a waste. I can easily fit 7 on a DVD with top quality. So I'll author the 7-9 GB folder, then use DVD2one to get it down to 4.36GB for burning. It looks fine. But it takes a lot longer to due, both because more data is being authored and because the re-compression takes time.

It's okay, but not a method I'd use all the time.

That's my take on it.

And yeah, 352x480/576 at 2500k would be 2-3 times better than 720x480/576 at 2500k. I hope whoever wrote that made a mistake.
