2 gig file size limits

[jwdove]

I've seen other posts here about 4 gig limits. I'm using an ATI All IN Wonder Pro to capture in ati vcr 2.0 format, 320x240 & I can't get past the 2 gig limit. I've got the latest player & driver versions & I'm using FAT 32 & it's supposed to go to 4 gig. I have a new 850 celeron comp. with 40 gig hd & 25 gig free. ATI's website says the AVI file format itself is limited to 2 gig. Is that right? Is there no way around the 2 gig with AVI? I can't even tape a 1 hour show with it. Thanks.

Hi,
Use AVI_IO or Virtual dub as these programs have a segmented avi which will split your avi file before it reaches the limit and continue capturing.

The filing system tends to have a 4GB file limit and no changing to XP or NTFS will sort this out

ATI are basically right. The AVI format uses 32bit pointers internally, and the way Microsoft originally defined the format these were /relative/ pointers, ie. they could range from -2gig to +2gig from the reference position. There are defacto web variants of AVI which use unsigned pointers instead, in which case these could range from 0 to 4gig - but if you want to have as many apps as possible be able to read your movie clips you should stay within the 2gig limit.

In actual fact, the safest size limit is 1gig, since earlier versions of media player used to crash if they were any larger than that.

You need to investigate segmented capture methods, since you'll have just as much trouble with the 4gig limit: that is the ultimate barrier for any FAT32 file.

Hehe, so its generally not a good idea to have a 24 gig 2 hour movie sitting on your hard drive?

Oh well, too late.

It's not bad, it's just that not all programs can read it. VDub should be ok, media player is hit & miss.

I think ironwood321 is confused,
Here are the file size limitations:

• FAT / FAT32 goes up to 4GB
• NTFS to 16 Exabytes (18,446,744,073,709,551,616 bytes)

MS Knowledge Base
Info on bytes etc..

I don't think he was confused, I believe he just mistyped. He typed "and no changing" instead of "and only changing", otherwise the reference to W2k/XP makes no sense.
