Serious 2GB file size bug in MF4 with fat 32 and win 2000?

Is there a 2GB avi file bug in MF4 when using FAT32 and windows 2000?

When I multiedit a dvd and try to fast export the footage to my hard drive it says the file size is over the system limit, which is impossible as the source dvd has less than 4gb on it. The source footage is DVD compliant.

If I save the file to a NTFS drive it saves, but the file size is only 2.5 gb!

MF3 will save an AVI as long as its below 4GB and I cann copy the 2.g gb file created with MF4 back to an Fat 32 drive -so it isn't a system fault.

It appears MF4 will not export to FAT 32 a file if it's over 2GB. This is wrong: fat 32 can handle 4gb AVI files!

System is AMD Athlon 2500xp

windows 2000 sp 4
512 ddr
80 gb boot drive with 60 gb free

Movie factory 4 with latest updates

PS, a few people have a similar problem which myself and others put down to MF4 changing the resolutiuon of a DVD to be compliant, clearly that might not be the case. It could be the same 2gb bug.

Why is there a 2 Gig limit? How can I avoid it?

Thanks for the link but it must be a bug in MF4. As the article confirms there is a 4gb file limit in fat 32 so it should easily save an mpeg file at 2.5 gb. I know its a 2gb problem as files under that size will fast export to the fat 32 drives.

And, MF3 will create a 3.99gb file on the fat 32 drives with no problem.

It might be a problem with the fast export procedure but it does need sorting out; i have to switch drive caddies around and install a NTFS drive just to save a mpeg movie with MF4!

There were some other threads whan peole edited a movie and it said file size too big, the presumption was the original file was perhaps recorded at long play on a stand alone dvd recorder (which might have been 352 x 576) and MF4 was resizing it to 720X 576 - I now think its the same 2 gb bug and MF4 couldn't create tyhe mpeg because it was over 2gb.

Sometimes this can be a limitation of the Codec either encoding the
video or decoding it. That's why some codecs require to use a
frame server.

I believe it's the codec your using to encode the file with.
Try exporting and encoding to a compliant mpeg2 file if it can be
over 2 gigs.

Try exporting the file as DV-Type1.

As stated in the article that Ploggy referenced:
This is a limitation of the Codec. I use to have the same problem with the Matrox codec. The file would record to 4 gigs but the codec's I
was using to convert the files could only work with 2 gigs so after half
the frames were processed I would get an error "Can't read file".
I was told to use a frame server to correct that problem.

QUOTED BELOW AS PER THE ARTICLE:
The FILE FORMAT used for the stored video can also have a 2 Gig limit. On PC systems, the most common format is AVI (Audio/Video Interleave). The older, Video for Windows (VfW) AVI WAS LIMITED TO 2 Gigs. Older QuickTime files (Mac or PC) were also limited to a 2 Gig maximum file size, even if the disks the files are stored on can be bigger; QT 4.0+ can address larger media files, but application support (even as of 2002) hasn't always caught up yet.

I don't think the problem is MovieFactory.

i've never had problems capturing or making 2gb file in MovieFactory 4. listen to what maddrummer3301 is saying about codecs.

when you edit a compliant DVD file in MovieFactory, the program will reencode the video according to the specified project settings. since the source viedo is 352 x 576, you need to CUSTOMIZE the project setting's frame size to match it because the default project settings is always at 720x576.

It doesn't matter if its the codec or not - it still doesn't work! There is no choice - if you want to fast export multi edited dvdv mpeg you have to use the Ulead codec, anyway: if it's the codec how come it works to a NTFS drive? same codec.

If someone wants to try this:

multi edit a DVD+r then right click the editied file and fast export. If it works it can export 120 mins in about 10 mins: as I say it works to NTFS but not fat32.

im not sure what's in your PC but mine works just fine.

Hi,
Your original post references the question to AVI file format/container.
Some avi codec's do have a 2 gig limitation.
You repeatedly said AVI.

I could duplicate this but you have to explain what the footage is.
A dvd that already is formatted and compliant witht the video_ts folder?
Or a file on a disk.
It sounds like your using the function "Edit DVD" and inserting a DVD+R
disk into the reader/recorder. Then editing & "Fast Exporting" the material.

I also have FAT32 & NTFS drives.

Sorry for the confusion! The source file is DVD+r from a stand alone dvd recorder, the output file is fast exported mpeg2 (which is an option from MF4).

Fat32 has a 4gb limit on AVI so I presume it's the same for mpeg? I think the 4gb limit is for all files under fat32. NTFS has no such file limit; but MF3 will create a 3.99gb mpeg2 file to the fat32 drive with no problem.

The PC is

Athlon 2500XP
512 ddr
Win 2k SP4
80 gb master driver and various large drives for capture.

Hi,

Yes, As far as I've encountered FAT32 has a 4 gig limitation on all files.
But, when it comes to video certain codecs can only work with 2 gig files
regardless whether it's NTFS or FAT32.

I will try this.
The fast export feature exports whatever the source video's properties
are. Nice feature to have. One doesn't need to set the "Project Properties" to match the source video when using "Fast Export".

Is the working folder pointing to a NTFS partitiion or a FAT32?
(maybe writing of the temp files could be a factor if working folder is
on a FAT32).

The last question I have is when you play the dvd using any software
player on the computer can you seek from the beginning to the end
and back (go anywhere within the movie). Or does the movie have
to play from frame to frame and seeking is disabled.

The working folder is on the fat32 drive (and is cleared out after every project). it can't be set to the ntfs drive (other wise I could just save to the ntfs drive)

I have an 80GB boot drive, and a 120 and 160 gb video drives. But I have to install an 18GB NTFS drive so I can export the dvd mpeg. The drives are in caddies.

Has anyone had a chance to try this yet?

ploggy · Post by **ploggy** » Tue Dec 13, 2005 6:06 am

just curious....

what release is your DMF3?

How can you save 3.99GB MPEG2 using DMF3? Are you capturing this video file?

DMF3 does not have an EXPORT MOVIE option. DMF 3.5 has it.

if you also have the screenshot of the error included it...

er, was that meant for me? Its MF4 (as said throughout the thread) and its a dvd imported from a stand alone recorder.
