QT for Windows: can’t read files over 2 Gb.?
Hi all:
Here’s what’s going on: we exported a 18 min. sequence as a DV Quicktime for one of our clients, which turned out to be a 3.94 Gb. file, and burned it on a DVD and sent it to him. The client, using Windows XP, copies the file to his machine, and opens it with Quicktime Player: the file gets played correctly… up to min. 9, when the image disappears and all he can see from that point is noise. We try here, using Windows 7 and Quicktime 7.6.9… and the same thing happens.
What’s going on? So far, my diagnostic points to the following:
-It’s not a problem with the DVD not accepting files bigger than X (2Gb., 4 Gb… whatever). As mentioned, both the clients’ Windows machine and ours (as well as our Macs) can copy the 3.94 Gb. file from DVD without problems.
-It’s not about Windows’ 4 Gb. limitation (since that only applies to FAT filesystems anyway).
-It’s not about the codec.The only conclusion I can reach is that Quicktime for Windows (at least the 7.6.9 version) has some kind of problem with extra-large files. Presumably the cutoff point is 2Gb., since our file was 3.94Gb. and it could only read half of it.
Has this happened to someone else? Is it a known bug?
Paulo.

Quicktime sucks on Windows anyway.
Quicktime is great on OSX.Deliver him a format that Windows can deal with.
Or send him a DVD Video.
Or send him a DV Tape. -
U didn’t mention if you had tested on a mac. Does it play fine on the mac it was created on? How about a mac it wasn’t created on?
[Paulo Jan] “the image disappears and all he can see from that point is noise”
Do you mean he can SEE noise? Like static? or video disappears and all you hear is sound?
Sounds like it could be a reference issue…this will happen if your QT is linked to a media file…you’ll find that it plays fine on the machine it was created on but won’t on others.
NTSC DV25 19minutes comes out to 4.4 GB…so your size sounds about right. Have you tried putting on a jump drive? DVD data can get kind of strange with large files.

It plays great in Mac, any Mac.
Send it to the client in another format… Great suggestion, except for this little detail: which other format can be read with certainty by any Windows machine? Uncompressed AVI? Too big. A DVD? WMV? Let’s remember: we’re talking about editing formats here, not delivery formats. At least with Quicktime you can be sure (well… until today) that, if you exported it in one of the codecs that come with it by default, any machine with Quicktime installed can read it.

Forgot to mention: I already thought about it being a Quicktime reference issue, so I checked, and it’s not. The noise the client is seeing are basically random color squares, as if the video file was corrupted.

[Paulo Jan] “Send it to the client in another format… Great suggestion, except for this little detail”
I’m not saying another format….DV NTSC is a pretty standard codec that most non-linear apps will be able to work with.
I’m saying another PHYSICAL delivery — get an 8GB flash drive and send it…or a portable hard drive. Single large files on DVD’s have presented issues for me in the past.

What program are they working with?
[Paulo Jan] ” if you exported it in one of the codecs that come with it by default, any machine with Quicktime installed can read it.”
This is pretty much true, what you are experiencing is out of the ordinary…so you have to track down the issue. DV-NTSC is a standard codec that every machine I’ve ever used will read…so you have an issue in your delivery method would be my guess…

The files were copied to the PC drive…what format is that drive? A 2GB “limit” sounds very much like the FAT32 formatting problem that comes up on this forum every other day. Just a thought.

Nope. I had them check the file size on their hard drive, and it was 3.94 Gb. Besides, nowadays almost all Windows XP installations are in NTFS. (And besides, our own Windows machine is in NTFS, and it fails too).

Sorry, I wasn’t responding to you, but to the previous guy (Paul Jay). In the end, we split the video in several smaller files and burned another DVD for them. Haven’t heard from them yet.

It’s been a while since I had to do this, but I believe you have to send it on an ISO 9660 DVD. Toast has that option.

Not a known bug.
One more test for you to try: If you put an uncompressed QuickTime file, at the 2 gig mark it dies? Does it die on your HD or just off the DVD?
