Ulead DVD Moviefactory - 4GB limit?

[KuroNeko]

A user on the Canopus forums claims that the Ulead DVD Moviefactory program can't accept mpg files larger than 4 GB.

Is this correct? Or is he just mistaken with the Fat32 limit?

If this is the case, this is a problem for long movies. Can you set multiple files in Moviefactory so that they automatically play one after the other, rather than you have to go back to the menu to select the next?

I believe he is correct, at least the MPEG files I've created over 4 gigs aren't recognized correctly.

There's a HUGE misunderstanding when anybody talks about this issue... particularly anybody on the CANOPUS forum, which is a notorious source of bad information, in my opinion.

1. There is a difference between MPEG files that are greater than 4gb and DV files that are greater than 4gb.

2. All of the new Ulead applications support DV files greater than 4gb... there's simply no question about that.

So anybody who tells you the Ulead DVD applications won't accept DV files greater than 4gb is just plain wrong.

The whining you're hearing has to do with VOB files...

Remember - most single-sided DVD discs have a capacity of 4.7gb.

The question is:

Can the Ulead applications can support VOB files greater than 4gb?

I haven't personally tested that, but I've read posts from some people who say they've been successful and I read posts from others who say they've had troubles.

I just got DVD WORKSHOP (just a few days ago) and I haven't had the time to check every feature.

But that's one I'm going to check.

One thing that really bothers me about software users and DVD authoring is they think they can use just about any 3rd party MPEG encoder and get great results with any DVD authoring software.

In a perfect world, that would be nice.

But the reality of the situation is that we just can't trust every MPEG encoder out there to produce files that are compliant with specs.

In my personal opinion, some of these encoders do not produce MPEGs that are equal.

So what I'm going to do is test DVD WORKSHOP using the built-in Ulead MPEG.Now encoder.

My tests might just reveal that those who aren't having the same degree of success as others are using 3rd party, external encoders - or - they may be encountering file size limitations that stem from their use of Video for Windows software applications.

The Canopus software is still based on the older Video for Windows media architecture, which is why file size limitation work-arounds such as "reference .avis" are necessary for Canopus users.

DVD WS may accept files > 4GB but will WIN 98 (Neko mentioned the FAT 32 limit)??????

Thanks Brian, that's the info I was looking for.

I'm using Canopus DV Raptor here at work...

But the inability to get the full benefit of NTFS is evident as I continue to use this product.

Actually, my home systems are now better than my work systems.

They're OHCI-based and can take full advantage of Direct Show and NTFS.

Oh well, the Raptor works okay.

Actually in terms of file size on your hard drive, DVD-R is 4.36GB NOT 4.7GB. Given that some authoring software (like MyDVD) has 500+MB of overhead, its easy to see how problems happen when you get near 4GB and the issue of who to "blame" gets confused.

Right.

And aren't many commercal DVD discs "dual-layered?"

(Meaning one can fit around 7gb or more on *them.*)
