MPG1 (1150bitrate) on DVD-R??

[King-Of-DK]

Is it possible to put a lot of TV episodes (DVD-Rips) on 1 DVD-R?? If i understand things correctly it is not possible to just burn VCD onto DVD-R,but i have to reencode,if this is right then after reencoding i can only fit 2 episodes on DVD-R as the files now are 2GB each instead of 400mb(1150) What i want is to keep my mpg files as 400mb (1150bitrate) and still burn to DVD-R,is this possible?

The files i create now is 352x288 MPG1 with a bitrate of 1150, if i create the same file in MPG2 will that be DVD compliant?

DVD supports mpeg1 and 352x240/288. So it is possible WITHOUT reconverting the video but you must change the audio to 48 khz.

OK,the original AVI has audio in 48khz,so would i be able to extract with Vdub,and the use the 48khz wav in TMPGenc when converting to 352x288 MPG2 with 48khz sound,will that be DVD compliant.

I think i am beginning to understand this res vs. bitrate thing. It is the resolution that defines if it is a VCD/SVCD/DVD then the bitrate says something about the quality of the video,right?

[King-Of-DK]

Hey Baldrick i really appreciates you helping me,but the Guide you linked to,explaines how to copy the Dat files,not how to convert the AVI´s to compliant mpg files..Am i right in asumin ALL MPG2 files are compliant,or are there restrictions?

[furball6969]

I think i am beginning to understand this res vs. bitrate thing. It is the resolution that defines if it is a VCD/SVCD/DVD then the bitrate says something about the quality of the video,right?

Right you are.

At standard VCD bitrate you can put about 7.5 hours on a DVD-R

352x288 Mpeg2 is NOT DVD compliant.

[King-Of-DK]

Great is it only MPG2 files that are compliant with DVD,or can MPG1 also be used,if i just resample the sound?? How do i calculate what bitrate gives how big a file??

I have calculated a bit,is it true that if i increase the bitrate to 2520 (svcd) i can hold about 3hrs on 1 DVD-R?

And i can without problem keep my original res of 352x288 eith the new bitrate of about 2520?

If i increase the Resolution,will the converted filesize equally increase? Or does it only state what kind of format we are talking about? Does it have an effect on the quality to increase the resolution?

[Baldrick]

I thought you had vcd dvdrips.

[King-Of-DK]

I start out with AVI. I have then converted them to VCD,but in the future i would like to burn 8-10 episodes to DVD instead of using 4-6 CD-R.

That is why i would like to know these things,how i get all the episodes onto 1 DVD-R without having to reencode all the files to some lame high bitrate and resolution,because each files takes 18 hrs to convert,If i could settle for 352x288 with a bitrate of 1150 that would give me alot of episodes on 1 DVD-R,and if i really want to do it good,i thought i could increase the bitrate to 2520 and keep the resolution of 352x288 and still burn to DVD-R

[furball6969]

If what you have right now is AVI and you want to put them onto CD's first then convert to DVD-R later I would use CVD. 352x480 @ 1600 - 1800 kbps; assuming your player supports it. CVD's use 48000 hz audio so absolutely no conversion would be required.

If you are going to use VCD resolution (352x288) and make standard VCD's the audio is going to be 44100 Hz initially and will have to be resampled to 48000 Hz when converting to DVD-R.

I beleive there is a max bitrate for Mpeg1 on DVD around 1800 Kbps.

ncreasing resolution without changing the bitrate will not increase file size.

[King-Of-DK]

You kinda misunderstood me,i have up until now produced mpg1 pal VCD´s,and now all i want to do burn to DVD-R instead of CD-R.. The good thing about DVD-R is the space on the disc,so i was thinking,even if i increase the res and bitrate to SVCD i will still be able to hold around 3hrs of SVCD quality MPG on the DVD-R.

But that is besides the point,i am getting it now..

I can do with the files as i like,as long as they are DVD compliant. What exactly does that mean? Can i use both MPG1 and MPG2?? If so all i have to do is resample the sound to 48khz and then burn? When i author the files in Ulead moviefactory,how can i make sure the program doesn´t convert the files onece more?

[King-Of-DK]

I thought i had it,then you go and make a whole new resolution

352x480 @ 1600 - 1800 kbps is this PAL or NTSC??

[furball6969]

Sorry, I forgot you were using Pal, I think the Pal CVD resolution is 352x576, it is also Mpeg2 but your encoder should have templates with most of these settings set by default.

[King-Of-DK]

Now i am alot more confused,because i only thought that there was these kinds of resolutions:

vcd = 1150 kbps... mpeg 1 352x288 (pal)
xvcd = 1500-2500 kbps... mpeg 1... 352x288 (pal)
svcd = 1500-2500 kbps... mpeg 2... 480x576 (pal)
xsvcd = 1500-2500 kbps... mpeg 2 ...480x576 (pal)
dvd = 3000-8000 kbps... mpeg 2....720x576 (pal)
vcd = 1150 kbps... mpeg 1... 352x240 (ntsc)
xvcd = 1500-2500 kbps... mpeg 1... 352x240 (ntsc)
svcd = 1500-2500 kbps... mpeg 2... 480x480 (ntsc)
xsvcd = 1500-2500 kbps... mpeg 2 ...480x480 (ntsc)
dvd = 3000-8000 kbps... mpeg 2....720x480 (ntsc)

So you can see my bewilderment when you come with a whole new resolution..

Any way,DVD compliance.. Can i use both MPG1 and MPG2 as long as the sound is 48khz??

[King-Of-DK]

Oh,and when i have my converted mpg1 352x288 with a bitrate of 2520 do i just burn as VCD or what?? How do i make my MPG into a vob file?

[energy80s]

You seem to be getting confused here. For a DVDR disc to accept an MPEG file directly, it has to be one of the following (for PAL) ...

MPEG1 352x288
MPEG2 352x576
MPEG2 704x576
MPEG2 720x576

Sound needs to be sampled at 48kHz and the GOP for PAL needs to be no more than 15.

[King-Of-DK]

And the final thing here.. I am making a test run,will this be DVD compliant??

mpeg2 480x480, 2 pass vbr, max bitrate 3000,min 500, avrg. 2000,48khz 192kbps audio??

Thank you,and what will the resolution be for NTSC??


Howcome the resolution is different than the ones i stated above??

Then my little test run wont do on DVD-R,as it is 480x480

What is GOP??

Will i be able to retain the AC3 if my AVI is encoded with AC3??

[King-Of-DK]

OK now i am using these parameters,will this work??

mpeg2,352x480,CBR 3000,48khz 192kbps audio

It seems also, that it only has to convert for app. 4hrs instead of 18hrs

[furball6969]

That should work fine; it is NTSC resolution but a PAL player shouldn't have a problem with it.

[King-Of-DK]

What is GOP??
Will i be able to retain AC3 if my AVI is encoded with AC3?? If so how do i do that?

The below resolutions are they only PAL? If so how are the NTSC DVD resolutions?

MPEG1 352x288
MPEG2 352x576
MPEG2 704x576
MPEG2 720x576

And both mpeg1 and mpeg2 are both DVD compliant as long as the resolution and sound is in DVD format?

If i want to burn my converted DVD mpeg files,how do i either convert it to VOB(nero will only accept vod files)?

Finally Wouldn´t it be easier to just download the templates for what i want?

What do you use when you convert AVI/divx/xvid to DVD? Do yuo have your own templates?

[King-Of-DK]

I just read about the CVD format,and i just figured out,that i can´t just use any resolution to encode in,as DVD video requires certain resolutions.

So the ones you gave me here are these both PAL and NTSC or only PAL

MPEG1 352x288
MPEG2 352x576
MPEG2 704x576
MPEG2 720x576

How do the NTSC resolution for DVD video look like??

Here is a question i would really like an answer to..If i edit the TMPGenc templates for SVCD to make audio 48000 instead of 44100 (can i just edit it in wordpad and change the value from 44,1 to 48???),how will the end result be? Will i have a SVCD quality ready to burn to DVD??

[furball6969]

This shoiuld answer some of your questions.


480x480 SVCD is NOT DVD compliant!

[King-Of-DK]

figured that out..

Listen what would you recommend if i have this NTSC avi,and i would like the quality to be a little better than SVCD and fit on a DVD-R?

The same thing only with PAL

My head is spinning from all these resolutions/bitrates/gop/audio and so forth.

How do i get the AC3 audio track into the DVD??

[King-Of-DK]

I want to thank you Furball. I think i have it figured out now. It is not that complicated.. I load the SVCD template,then unlock it,i then change audio to 48000 and res to 352x480 and have a CBR of 2520.. This should be compliant with DVD right? And i will be able to put 2 movies on 1 DVD-R,right?

[energy80s]

Right, I thought you were transferring PAL material. For NTSC do this ...

Load the NTSC SVCD template in TMPG.
Load the Unlock template.
Go to the resolution and change it from 480 x 480 to 352 x 480.
Go to the GOP and set it to 18.
Go to the audio tab and set the sampling frequency to 48k @ 224kbps.
Set the bitrate to whatever you like - as it's being transferred onto a DVDR disc, holding the bitrate at 2500kbps isn't necessary.

This will (should) give you a compatible MPEG 2 file to transfer onto DVD.

Some things to clearify (once again):

CVD is 352 X 576/480 with 44100Khz Audio.
If you keep the resolution, boost the audio samplerate to 48000khz and limit the GOP lenght structure to 15 PAL/18 NTSC then you have a great mpeg 2 file which depending how you multiplexx it, you get xCVD or 1/2 D1 DVD

352 X 288/240 can also be used for both mpeg 1 and mpeg 2. The gop limitation also applies here, so the audio. But, there is no bitrate limitations! So, you can make a xVCD or a xSVCD (like sefy's SxVCD) and still burn on DVD-Video without problems. This is the reason many standalone DVD Recorders allow to record that way on you DVD discs.

Finally and just for the record, there is also a useless resolution used by DVD: 720 (or 704) X 288/240 ! I had a long convertation for the subject with some proffesionals and they told me that this resolution is a better alternative than 352 X 576/480 for progressive screens and that's why exist. Some US HDTV owners may do some tests to confirm this please!

[Sefy]

That resolution actually sounds perfect for Wide Screen movies without the black bars, but I think it would look weird if a DVD won't know to add them on a regular TV.
