MVCD Compatibility

[sbielski]

Hi there

Does anybody know if SVCD2DVD is capable for MVCD? Or does it depend on the DVD-Player? I never tried MVCD, but a friend wants to use SVCD2DVD for mvcds.. I got him to buy SVCD2DVD, because it's a really great prog

Someone had a similar question about kvcd. There were no problems there so i see no issue with mvcd. Let us know if that is the case.

Hello,

i have problems with some mvcd´s. The movie is not been added to the assets.

The problem is not for all mvcd´s some let me add them to the assets.

In the older version 1.51 i have no problems with adding the movies.

Can you ftp me one that doesn't work (and one that does)?

[kmorber]

Hello,

i got it working. I cut away with tmpeg the last second of the movie, after that the movie let me add it to the assets.

Good. So MVCD work ok in general then? If so approx how many hours worth can you fit on a DVD using SVCD2DVD?

[kmorber]

I think about 8 or 9 hours!

mvcd partly works with mvcd.
i can author 5-7 files on 1 DVD. when i want to watch them on a pc (with powerdvd os something else) it works fine. but when I want to watch them on a standalone dvd player 90% of the movies stuck after a few second. by the movie which don't stuck i can only use 4x fastforward. i would be very plessed of help....

I suspect it is the GOP length. Do you know what the GOP length is for MVCD?

[freak]

what is GOP ?! when you interpret the word for me i maybe can give you an answer

[ChrissyBoy]

GOP: group of pictures

There is a fixed max GOP length in the DVD spec for NTSC & PAL. I am thinking that MVCD may not fall within this max value. As there is no reencoding taking place then the GOP structure of the assets is replicated in the DVD and so must be DVD compliant.

Easiest way to check this out is to upload a mvcd mpeg to ftp://BetaTester:b%40dger@ftp.svcd2dvdmpg.com:7676/MVCD/ and i will take a look.

[freak]

ok thank u. i will upload 2 movies. one which doesnt work and one which work...

[freak]

the ftp doesnt work...

[ChrissyBoy]

It does. Make sure that you are using PASV ftp as it may be an issue with your firewall/router... If you are using Internet Explorer:

[freak]

i use flashfxp...
other ftps work. but this one doesnt.

[freak]

ok now it works...
i will upload 2 movies in the next day

[freak]

ok i uploaded 2 files...
mat1 doesnt work...
pred work...

[ChrissyBoy]

ok i uploaded 2 files...
mat1 doesnt work...
pred work...

I think it is the other way around... No matter. It works now:



Pred has a RIFF header. Prior to RC1 these would not import into SVCD2DVD..... In RC1/2 they do.

I have made a small omission too in the code but after the RIFF2MPG bit has completed reload pred.mpg and it should work. The original is renamed to xxx-ORIG.mpg. The asset reload should be automatic but like i said i missed that bit!

Let me know therefore if you have sucess with RC2

[freak]

to make an DVD image of the moviez is no problem...
my problem is, that matrix doesnt work on an standalone dvd player and predator does.

[ChrissyBoy]

ok. I will try on my standalone.

[ChrissyBoy]

Well my suspicions were correct about the GOP length. Matrix has an average GOP length of 80+.

It should be 15 maximum for PAL mpegs in order to be DVD compatible.

Pred has an average GOP length of around 20 which again is too high but many DVD players are forgiving to some degree…..

Your options are to re-encode the mpgs to have a DVD compliant Max GOP length.

Sorry about that.

Is such a high GOP length part of the mvcd "spec"?

[freak]

can you say me how i can re-encode the files ?! which programm do i need ?!

[freak]

what about an answer ?! i would be very pleased...

[ChrissyBoy]

Well you will need an encoder which can do mvcd templates.... otherwise your resultant file will be a lot bigger than the original.

As i have never encoded mvcd i am not sure which will do the job, maybe tmpegenc?

[freak]

issn't tmpgenc only for avi to mpg ?!

[ChrissyBoy]

Not as i remember.

[freak]

i don't understand it....
where is the different between bruning mvcd on cd and mvcd on dvd ?! on cd it works....and dvd not ;( when i burn them as data-dvd it works too, but the quality is worse
