Is this true??
Posted by Alieninnovation on January 22, 2006 at 9:05 pmI found this on a post early but never could get answer..
The DV files shouldn’t be a problem. But HDV…now that will be. You need the latest version of quicktime and FCP for you to view them. On a PC, they can’t vew them…due to the GOP structure and way FCP captures the footage. Avid Express Pro HD now can capture HDV natively, but in a different format (wrapper…codec, whathaveyou). You aren’t going to be able to exchange the HDV files this way.
As for teh 2 GB file limit…that is the reason many PC formats limit file sizes to 2GB…because PCs have trouble reading them.
Is this true since I was told other wise on the GOP structure, that they are all the same no matter what.
Maybe somebody can give me the breakdown on GOP…Thanks

Actually I’ve found I need to limit quicktime files to 1.7GB for Windows users to be able to read them. Anything above that and it doesn’t work. Best bet is to give Windows users an Image Sequence for anything that will create a movie file above 2GB.

I find it highly doubtful you’ll be able to move media across from FCP to AVID unless you use the Automatic Duck Plug-in, but even there, I’m not sure if it will work for HDV.

January 22, 2006 at 9:34 pmDear Alien,
You kind of cover a load of bases in your post, but I’ll hit the most important points that pertain to FCP.
You don’t have to have “the latest” versions of FCP and QT, but you do need FCP 5 and a recent version of Quicktime to edit HDV natively in FCP. And, the so-called native files that FCP creates are not exchangable with apps on a PC.
Not sure about you point regarding the 2gb file limit in Windows, which is no longer the case for the most part under Windows XP, but this has little to do with exchanging native HDV files between platforms.
And, the GOP structure is determined by the camera when HDV is recorded to tape, so true, it would be the same in all apps, but that is also not terribly germaine to the issue of exchanging files between platforms as it is not the issue that prevents FCP HDV files from playing on PCs.

Actually it still is very much an issue with Windows XP. I work with an editor who runs the latest AVID Adrenaline on XP and I have to be very aware of file sizes when creating animations for her. 1.7GB file size or under, I’m ok to give her a Quicktime. Over 1.7GB, I give her an Image Sequence.

This is certainly not germaine to the original post regarding exchange of HDV files from FCP. It has nothing to do with the reason FCP HDV files are not readable on a PC. However, since you brought it up…
There are several reasons why the 2gb file limitation might be an issue for you when exchanging your QT files with someone on a PC, but it is not an XP issue any longer. It may be an Avid limitation, or a limitation of the way their hard drives are formated, but Win XP is not the issue. For some reason there are still some apps that adhere to the outdated 2gb limitation, probably to maintain backward compatibility, but the latest versions of most PC apps do not.

BTW, I’m writing from a Win. XP machine now and playing back a 3.8gb QT file on QT player as I write.

That’s a very exciting thing, I guess. Windows can finally play a file larger than 2GB. Nice to know they’ve caught up to the Mac’s of years ago.
I’m pretty sure it was AVID tech support that told us about the 2GB limit on XP. I don’t do Windows so I really don’t know.

January 23, 2006 at 1:42 amPerhaps an OMFI issues. Avid that use the OMFI standard limit to 2 GBs. Even in that case, it should break the file up upon import. So I am little confused about why they have that spec. MXF creates datafiles much larger than OMF.
Also, as I create Data Description Protocol files on a daily basis which are up 4.7 GBs in a single file, I can also say without a doubt, that XP has zero problem with files greater than 2 GBs. That is of course saying that the system is using NTFS.
The method of transfer may have something to do with this. A universal way to transport data files should be kept under 2 GBs so others can read them. That might be the issue.

January 23, 2006 at 2:09 amThe 2 gig file limit as far as the OS goes was due to the file system of the hard disc. Since Windows NT 4 in 1996, or there abouts, the NTFS file system did away with the hard limit of a 2 GB file. There is still the option to use FAT32 (up to 4GB file size) in Windows XP. It’s made available mostly for backwards compatibility. Add to that there are 2 different flavors of AVI. AVI1 and AVI2, AVI2 can handle file sizes over 2GB where AVI1 is limited to under 2GB. This was unfortunatlely the way Microsoft chose to go. Backwards compatibility to the extreme is pretty much the status quo for them. It certainly makes troubleshooting issues on the PC side of things challenging.
All that being said, I move DV AVI and Quicktime files back and forth between FCP 5 and Premiere Pro 1.5 without any issues related to file size. I wouldn’t dream of passing “native” HDV files back and forth though.

January 23, 2006 at 5:19 amThe 2GB limit you’re hitting is a result of the Avid not allowing you to have a single media file that exceeds 2GB. When you capture from tape into an Avid the Avid is able to string together multiple 2GB media files seamlessly in the background, but when you Import it cannot, so you are more likely to hit the single-file-2GB limit. What you’re seeing isn’t an OS thing, it is an Avid thing.
