time on a VCD?

[Beev]

I have an avi that I want to convert to mpeg to burn to VCD. Now, the .avi file is about 700 megs, but the film is actually 3 1/2 hours long.

If I split the .avi file in 2 before burning, will it still fit? It means that I will have 2 files that are 1hr 45 minutes long. Will this work? or am I going to have to split it onto 3 or more CD's?

Thanks in advance.

Yours, Beev

If you stick to the VCD standard, you'll have to use three cds to get 210 mins media on them. Unless you make something like a KVCD (which is not compatible with all players, but many) which would enable you to put it on two cds. The website is http://www.kvcd.net . I recommend splitting your movies by specifying the source range with Tmpgenc (to eliminate sync probs) and setting up three encode sessions in a batch. There are guides here at VCDHelp.

I have a similar problem. I ripped a movie and created a mpg file out of it. The mpg file is 1.6 GB in size, and the movie is 2 hrs and 36 minutes. When I try to burn a VCD using Nero, it says that the file size is much bigger than the CD can support. I used the following guide to rip and create the mpg file:

Software used:
DVD2AVI v1.76
TMPGEnc V2.55.38.142

What should I do? Should I create 3 mpg files using TMPGEnc's set start frame option, or is there any other way?

Thanks.

Thanks for the info. What software do I need for KVCD? Ive never come across this format before.

KVCD isn't a format, it's an XVCD template for TMPGEnc that a guy called Kwag did. It's not unlike you doing a XVCD template and calling it GVCD or something like that, or Sefy's templates (SeVCD, etc) or any of a host of others. Confusing? Yes. Worth trying? Yes.

Hi Mirror_Image and all!:

KVCD started out just like an XVCD template with some minor additions.
KVCD is not a template anymore. It has it's own GOP structure, which is completely different to every standard ( and non-standard ) (X)VCD templates around. It also has it's own new Quantization Matrix, which is completely different from every Q. Matrix around. It doesn't even resemble any Q. Matrix from CCE, TMPEG or any other encoder.
So KVCD is now indeed a format ( with the combination of the GOP+Q.Matrix) completely different to every other template.
The new Q.Matrix was integrated and posted in the new beta templates posted yesterday. Take a look at the results. It's a whole new ball game
Here's the link with the new beta templates and three samples:

As Ed McMahon would say, "I did not know that!" (about Kwag tweaking the GOP and QM). They look good though, I do know that.

Take a look at this:

Can you tell the difference from this and the original DVD?

Thats great quality. did the entire movie fit on one disc or did it have to stretch to 2?

umm... interesting, but the quality still sux compared to the original dvd. (unless u got a really crap one in the US or something). the PAL dvd is 16:9 and looks way better.

anyway, if u resized from 720x480 to 704x480 u are blurring the horizontal pixels. avoiding resizing, or resizing evenly is best.

perhaps doing the smallest amount of noise filtering would help, as well as using floating point if u aren't already (but it looks like u aren't). and not doing that damn resizing...

Hi Beev:
The total size, with 224Khz audio, was about 1,526,091KB. So it splits, with room to spare, in two CD's.

Hi mikk:

You PAL guys have the best, we have to deal with NTSC
The 704x480 is done for a reason. 704x480 is a valid MPEG-1 "stills" resolution for all VCD's. So every DVD player that can play a VCD, will play a still 704x480 picture. And because of that, most do play mpeg video at 704x480, but many don't play 720x480. As for noise, well, as seen on my HDTV and comparing it to the original DVD, only in a couple of places in the movie I can tell a very smalll ( and I mean very small ) difference. And that's because I'm looking exactly at difficult scenes. Still, no matter how hard we try, a re-compression will never be the same as the original material.

Same topis but different questin. I have another film that is already an mpeg-2 format ready to be burned to a CD.

However, it is 830 megs, but only 73 minutes long. Will it still fit to one CD? I know that it is too large a file size but it is within the 80 minute capacity.

Thanks.

an 830mb file needs at least 830mb of cd space. a 90 minute cd is what u need.

kwag, i get what u're saying about using 704x576 mpeg1. if using mpeg-1, i also stay with vcd2.0 standard resolutions, but when doing mpeg-2 encoding, i use dvd or svcd resolutions.

i suggested the noise reduction to get rid of noise from the original encoding onto DVD. By removing this noise, the vcd encoder is not trying to encode it (which it can't do successfully at low bitrates anyway).

anyway, your own opinion is the one that counts. once i start pointing out faults to you, u'll drive yourself crazy because u'll see them all the time. when i watch a dvd, i see mpeg artifacts almost all the time, especially on high quality equipment. nobody else sees these artifacts until i point them out...

i'm making another thread about getting PAL dvds in the US, i wonder how it'll go.

[Beev]

Would I be able to overburn it? I thought that is what it meant? I may be wrong.

[mikk]

you can't use an 80 minute cd. find a place to buy 90 minute CDs. When you burn the disc the software will have to be set to overburn, otherwise the burn will stop at 80 minutes. also check that your burner supports 90 minute discs, if it doesn't then u might damage your burner.

[Beev]

Thanks. I have a fairly new 32x burner, so Im sure it will support the 90 min cd's. Thanks for the info.
