Capture file size greater than 2Gb...

I am using Adobe premier 6.1 to put together my holoday video. A good idea at the time. I use pinacle DV200 software to grab sections that I pin together in Premier, but I hit a snag. I got a section that runs on a bit, and apparently I can only grab a 2GB file. I am not all that comfortable with the grabbing proces on Premier, but am I gonna hit the same issue with premier?

I have oodles of disk space and memory, and need to capture about a 20 minute section in the resolution of my choice. There are no convenient breaks in the movie to pick together, but if I do manage it that way, how will the finished project build as it would be greater than 2GB in total?

Thanks for any help.
Regards
Nigel.

What OS? You should be able to "link" movie clips in rather than creating one HUGE movie file. If theyre linked the size will never exceed 2gb.

I just moved to millenium. I initially got the error under Win98 though.

Where is the limit imposed? I have a 4Gb PGP disk file, so I guess its not a filesystem thing.

The problem is I need to create a Video/VCD... that means I need an AVI or Mpeg to burn, play... the print to video option under Premier did play a 'preview' version of the movie once, but for some reason now only flashes the screen black for asecond or two then returns to the project screen.

Can I put the new movie back onto the camera on a blank tape via the firewire? Do I need any special software or does my camera require any special features or is the DV port bidirectional by default. I have a sony DV camera... can;t remember the make and model.

Ahh in windows i have no idea. Maybe someone else knows
VirtualDub (freeware) allows you to capture movies greater than 2gb by 'striping' the file across your hard disk. You can download it at www.vcdhelper.com....

It also has a set of diagnostic features that allow you to determine optimium frame rate and resolution for your machine.
Oh, and the 2GB limit is imposed by the capture program that comes with the OS. VirtualDub provides it's own capture program in order to bypass this.

The 2 GB is not a filesystem thing, it is an avi thing. Normally avi has a 2GB limit (something like the 640kB limit ? ;) There are several ways to bypass this. For example if you buy a Video In card it might have a fix for recording files bigger than 2GB or just a video software that like said before. I know from a friend who bought an ASUS Graphics card with video in and he said ASUS had the 2GB Bypassed too ... but you are using Firewire and with that I don't have any experience.

To TheRedGuy, didn't you mean www.vcdhelp.com ? just a typo i guess ...
MarcG,

vcdhelp.com and vcdhelper.com both take you to the same place, i.e they are synonymous. Having said that, the page is titled vcdhelp so I guess it was a typo ;-)

Just for completeness this is from John McGowans AVI Overview (http://www.jmcgowan.com/aviauthor.html#VfWCapture):

Under the 16 bit FAT (File Allocation Table) filesystem used by DOS, disk partitions are limited to a maximum size of 2GB (Gigabytes).  In DOS, a hard disk is divided into 512 byte sectors.  DOS Version 4 added support for 32 bit sector numbers.  2 raised to the 32 is roughly 4 billion, multiply this times 512 bytes in a sector to get the 2GB limit.  FAT16 partitions are limited to 2GB, necessarilly limiting AVI files to a maximum size of 2GB as well

and:

The new FAT32 filesystem available with Windows 95 permits partitions larger than 2GB.  Unfortunately, a 1 or 2 GB file size limit is hard wired into some of the code for the Microsoft Video for Windows.  In particular, the RIFF parser code and MCIAVI (the MCI driver for AVI files) contain a 1 GB or 2 GB limit hard wired into them.

There are workarounds to to the 2GB limit detailed at the above url....
