Tmpgenc Size Limitation Warning

[deb]

I've recently been using TMPGenc to create MPEG2 from AVI using the settings in the FAQ. Every time I set it up, the file is larger than 4070 and I get a warning that a file that size may not be readable by software applications.

Will the file be readable in a set top DVD player if it's over 4070? I have XP so I thought I didn't have to worry about file size problems on the computer - is this correct? Sometimes I may not choose to make a menu, so how large can I make the file and have no set top DVD compatability problems? If I do make a menu, how much room should be left to accomodate it?

Thanks for the help!

You have XP, but are you running the NTFS file system, or the FAT32 file system?

p.s. Please fill out the "computer information" section of your board profile!

Hi Mirror_Image,

I tried to edit my profile, but I'm not sure how at this point.

I am using NTFS, not Fat32. I didn't think the file size was a problem because I was using XP with NTFS, so I made one MPEG2 that exceeded the 4070. However, when I ran Movie Factory it wouldn't recognize any but the first 20 minutes or so. So I assumed it was a file size problem since Movie Factory recognized my other MPEGs.

So now when I configure TMPGenc, I fill out the 2VBR with 8000 max, 6000 avg and 2000 min - plus some other settings that I found in the FAQ. This always turns out too big, so I use the percentage reduction until the size reduces to 4070 (You can see the big rate reducing as the % reduces).

I wondered if this was the best way to go about this. Maybe I don't have to make it so small, especially if I'm not going to add a menu.

Any suggestions?

Thanks,
Deb

You are not tell us what program is giving you this warning. As for the size, you have to author your MPEG file to a DVD before a settop player will even recognize the disk. The DVD spec requires that all files be less than 1GB in length (which your authoring SW will handle).

As for the error, it may be coming from a piece of software that is not NTFS aware (early Win95??). Most modern releases should have no problem with the size as long as your system doesn't. I routinely have files greater than 2^32 and use these to author DVDs (WIN2000PRO, P4, 512MB, twin 80GB, DVR-A04, etc).

The warning is coming from TMPGEnc. I use the wizzard - first I make the setting changes in "Other" and when i get to the screen that shows the file and how large the program expects it to be. When I try to move forward, I get the error message saying the file wil be too big.

One time I ignored the warning and made the CD so that it was small enough (I thought) to fit on a DVD, but larger than 4070. Then when I tried to bring the file into Movie Factory it wouldn't see any but the first half hour or so. With my level of experience, though, I could have done something else to cause the problem.

It just seems as though for the times that I'm not going to add a menu but just the movie, then I could make a larger MPEG file.

So I ask - for a 4.7 gig DVD, how big of an MPEG can fit - with and without a menu?

Thanks!

for a 4.7 gig DVD, how big of an MPEG can fit - with and without a menu?

While the specifications for the media describe the disc as being 4.7G, it is actually 4.3GB. This is because we users calculate the free space (1 gigabyte = 1024 x 1024 x 1024 = 1,073,741,824), which is the method used by Windows to calculate free space. The disk manufacturer specifications speak in terms of GB (1000 x 1000 x 1000 = 1,000,000,000). hard drive manufacturers (and the vendors that move their products) misrepresent capacities in a similar way.

So am I understanding you correctly - we can fit 4.3 gb, which probably looks like 4,700,000KB?

Does it require any slack room for running? How much roon does it take for a menu? Could I actually make a single MPEG of 4.3 gb and burn it by itself (no menu) to a DVD and it would run? I didn't know if the set top DVD players could read files over a certain size.

Thanks,

Your authoring software will break up large MPEG files into 1-Gig vob's.
As for the menu, depends on how big it is. No need to play dangerous so leave some slack. I use VCDHelp bitrate calculator like this: add 2 minutes more over actual footage and subtract 100 kbps off what the calculator gives me. That way around 90-95% of disk is filled. I don't want to spend 17 hours encoding a movie and then find out that I am 1 MB over the limit
