AVI to VCD

[Jaxy]

Hi gurus--
am really a newbie.. need your help..

I have got a Avi file it says it is DVD rip -Xvid.
I wanted to convert that file to VCD
I tried Nero ver 6 to burn that as vcd on CD
The avi file size is 700 MB
When I attemted to burn it, the file size shows me more than 800 MB and time shows 121 minutes or something like this.

So I want to know why the file size shows larger to convert to VCD.
I thought the file size should be smaller since VCD has better compression than AVI..

so at the end i was not able to burn it as VCD, The nero asking me to insert a disk that has more space. ( I used blank cd that has 700 MD space)


so how can I burn the dvd-rip, xvid as vcd on a CD???

thanks..

look through the guides, ur gonna hafta convert this xvid file to mpeg1 so u can make the vcd.

and depending on which compression method you use for the avi file, xvid is much better compression than mpeg1 (vcd)

Use TMPGEnc Plus and encode to SVCD.

Some misconceptions in your post...

1- 'Avi format' means absolutely nothing in terms of quality or size. Degrees of compression, audio and video codecs used, screen size etc all influence quality and size of the resulting file. Divx and Xvid video codecs for instance produce excellent compression of video data. Some codecs like Huffyuv or DV codecs are less lossy (i.e. do not lose too much detail from the source) but produce huge files.

2- VCD on the other hand, is a standard. As such, VCD-compliant footage always has the same size (quality of course varies according to quality of your source and how efficient your encoder is at converting it to VCD-compliant Mpeg). A rule of thumb: a VCD puts slightly more than one hour of footage onto one 650 meg disk.

So if you encode a 120 minutes movie to VCD, you should get a Mpeg file that is roughly 1.3 gig in size, and needs to be cut into 2 parts if you wish to burn it.

You will often find 2h movies that can be compressed reasonably well into one 700 mb CD with Xvid. If you want to convert the same movie to VCD, though, it will invariably take more space.

Thanks for the tips..

but i seem dont get it... sorry I'm trying to get this in the head..


1 - you said>>If the AVI does have nothing to do with quality or size:

but AVI format is not a XVID or DIVX format, and AVI does not have high compression capability than the XVID or DIVX these are diferent format.. right ???

- I see online a lot of AVI that is XVID, and that fits on a 700 MB CD
how come a AVI could be XVID????

I guess I dont know the difference

I gues I am trying to say a VCD is MPEG1 and AVI is not, and mpeg1 has higher compression rate than the AVI, then how come converting AVI to VCD(MPEG1) takes more space..


Hope i'm making some sence



Thanks

Avi is the container, DivX, Xvid, et al are the contents. It's how the avi is encoded.
Converting any avi to any mpeg is reliant on final bitrate. VCD has a standard bitrate of 1150kbps. At that rate, you can only fit so many minutes of ANY avi on one cdr.
SVCD allows more options, so you can use a higher bitrate to encode and get less video on the disk, or a lower bitrate, and get more on the same disk.
Start by clicking on the VCD and SVCD links on the top left of this page, under WHAT IS.

Thank you guys a bunch --
