Clips with .sml suffix
 
What exactly are clips with .sml as the suffix. I noticed it on clips that span 2 cards.
But that aside, I've gotten that on a few clips. These clips in question were on the long side.
Like 20 minutes, and it was all on one card. What does that mean? Could it have to do with a clip that's out of sequence? In other words, switching cards before a lengthy shot, then going back to the other card. Thanks.

I'm not exactly sure (and I was wondering that myself), but I think you're right on it having to do with the clips being long.
My guess is that because of the file system that the SxS cards are, they can't have one large file (say over 2 gb?). And if you look in the transfer software when you're looking a a .sml file you'll notice a little bar 1/2 way through the timeline. I think this is where the split in the files is. But when you go to transfer the file off the card, it will mend the two separate files into your one large file.

It just a guess, but that's kinda what I was thinking.

SMI Describes the clip. If the clip "spans" that it describes the "stuff" needed to put them together as one clip.

Yes, I know that, but as I say, it has been doing it on long clips that don't span 2 cards.

FAT32, the format used for the SxS cards, has a 4GB clip size limit. Therefore any clip over 4GB is spanned. That's roughly 12 to 13 minutes at HQ give or take.

So spanned doesn't necessarily mean the clip goes on 2 cards? If I have a 15 to 20 min clip, it'll get split up on the same card? Do I have that right?

Craig Seeman July 13th, 2008 11:00 PM
Yes, anything over 12-13 minutes (HQ) is spanned (4GB).

By definition, are you saying "spanned" always involves 2 cards? Or does that simply mean larger clips are broken up on the same card. I think that's what you're saying. To me, "spanned" seems like it should always refer to 2 cards.

Craig Seeman July 13th, 2008 11:23 PM
No.

Any clip more than 4GB is broken into two. Any clip that goes across two cards is also broken into two.

Yes, I get it. Though the question involved you definition of "spanned." I was just wondering a clip, broken in 2, on one card, is also called "spanned." Though you cleared it up enough, no need to beat this to death. Thanks for the input.

Piotr Wozniacki July 14th, 2008 01:01 AM
Craig, I'd personally agree with the others' opinion here that "spanned" should be reserved for a situation of involving two cards, while the 4GB chunks due to FAT32 are results of "splitting". This way, we have two unambiguous terms. Don't you agree?

Dave Morrison July 14th, 2008 09:35 AM
I agree with Piotr and others....."spanned" involves one file spanning two cards, "split" means one large file split into two parts on one card.

Craig Seeman July 15th, 2008 07:17 AM
An Overpass can span a highway, a bridge can span a river. In the first case they are on the same island on the second there are two separate islands. To me "span" is when two separate bodies are connected and in the case of SxS, that's .smi. It's the same .smi whether on one card or two. To me, to describe the .smi in two different ways (same card vs two cards) adds to the confusion about what the file does. The file serves a single purpose and I think a single term should describe it.
