Output AVI files are too big on dvdwshop 2.0 pls help any1

[k2005]

HI i'm making a song dvd, i have 50 video songs which come up to 3gb but when i import them to dvdwoshop 4 songs are already 2.gb why doe it show the size much bigger than it reali is?

Do i have to change settings are soemthing
Pls help

thanks

What type/format DVD are you making? As far as I know, Workshop can't make a DVD-Audio disc.

What's telling you 2GB? That much spece is getting eaten-up on your hard drive? Maybe it's reserving space for AVI video??? (MPEG-2 video wouldn't reuire that much space.) Maybe it's mostly "overhead" and it won't go much beyond 2GB as you add songs???

Try "burning" the 4 songs onto your hard drive, or a DVD-RW and check the file size of the result.

Like DVDDoug, I'm not sure what you are trying to do with an audio disk and DVDWS. Anyway, it is probably converting your songs to PCM/WAV files which take quite a bit of room (although not normally 500MB/song).

Hi
there no its not an audio song dvd its a video songs dvd. Each time i add a song to the videos it goes up in space and 4 songs have gone up to 2gb.

PLS help!!!
thanks

are you talking about music videos?

If so, what are their attributes? mpeg, divx, xvid, other type of .avi, etc...?

If they are not compliant for the type of disc you are creating, then DVD WS will need to encode them. DWS will use your project settings to calculate your space requirements. So check what your project settings are to see if the re-sizing makes sense (i.e. based on the minutes of your source videos at the settings used in your project).

Hi,

If you are making a DVD of music videos, you will encode this to MPEG2 in the final process of the authoring.

AVIs and WAV files will total to more than a DVD disc prior to encoding.

Not sure what you mean by this

Hi,

DV AVI content is about 13GB per hour. Uncompressed NTSC AVI content is 5 times that, or about 65GB per hour.

Two hours of content using AC3 (Dobly) encoding can be put on a 4.3GB disc.

but that's making the assumption the OP is talking about dv .avi or uncompressed .avi. If they have divx or xvid .avi's, then the total could be more or LESS than when encoded for DVD (based on bitrates for the dvd encoding).

also, you can get more than 2 hours on dvd5 discs, depending on your encoding bitrates -- whether it looks any good depends on the source type/quality...

Yep.

That's the assumption I'm making. The poster didn't overwhelm us with information.

Lower bit rates notwithstanding, 2 hours is a very good target for any budding DVDist.

Longer programs will require very good encoding technologies, Canopus's ProCoder or Cinema Craft come to mind.

I agree that the OP didn't supply alot of info. However, there is some info that indicates they are dealing with HIGHLY-COMPRESSED source videos (like divx or xvid .avi's). The fact they have a number of videos that total "x" space, but when placed in their project, the size increases tremendously for just a handful of their source videos. I could be all wrong, but that's why I asked for the attributes of the source videos...

Hi ,
thanks to all of you for helping , sori i didn't supply much info here is some i hope this helps.

I either wanted to import AVI's which i compressed from the programme Auto gordian knot. Or just mpeg but i found my mpeg files were too big , each were around 300mb, 400mb.

So i decided to compress all 50 video files to avi and yet still its the same its actually bigger than the mpeg ones which are 400 mb long and the AVI'S are like 40 mb long. when its imprted i don't know why and i hope i can change it so they all fit.


here is the info on both MPEG file and AVI file.

Hi,

It appears your source videos are HIGHLY COMPRESSED -- using very low bitrates, and when you encode for DVD, the bitrates are much higher (using 6000kbps).


Think of it like this (these numbers are FAKE, they are just being used to illustrate what is happening, and do not take into account the audio):

Given a 10-second video
-source is 1mb per second = 10mb
-target is 6mb per second = 60mb

Your source is the 1mb, and your target is the 6mb bitrate -- so your small source videos increase in size because the new encoding bitrate is higher than your source bitrate...


EDIT:

Just to re-iterate, my numbers in the example are FAKE. Have a look at your actual bitrates:

Source = 110.91 kbps
Target = ~6,000 kbps

Can you see why it is making them larger?

[k2005]

So the bigger they r the better?
sori i reali am not advance in dvd worshop 2 . Can u e-mail because pm doesn't work
So how do i change this to fit 50 songs on one dvd. is there anyway?
how do i check the bitrate?
can u e-mail me with details at: Krupa_t2004@yahoo.co.uk

[k2005]

How do i change my biterates?
if so does that mean i can fit my 50 vidoes?

thanks,
