having problems with uncompressed 10-bit qt
I captured some spots in 10-bit uncompressed format. They are quite large but play beautifully on my computer. Unfortunately, the 3 other people who have tried to watch these files (on their computers) are getting sound, but seeing no video.
I cannot understand why this would be. Do they need to have FCP on their systems to play uncompressed? I can’t believe that would be the case, since the movies open in Quicktime Player (at least for me).
Please help!
Thanks.

They need to have the same uncompressed codec on their systems in order to play the files correctly.

That’s what I was afraid of. They requested uncompressed quicktimes, and I was hesitant, as I smelled trouble.
I captured through my Aja Io, so obviously the files use the Aja codec. Any idea whether these people will be able to install the Aja codec into their systems if they don’t have Ajas and FCP?
If they can’t, is there any other way that I can provide someone with an uncompressed file that they will be able to view?
BTW, thank you so much for the amaingly quick reply, Walter.

It’s not an AJA codec actually, it’s an Apple Quicktime codec. Probably the 8bit 4:2:2 uncompressed. I think if they have the latest QT 7 installed on their system, it should be installed with it.
Or they may need to simply get it from you if they’re on a Mac.

Hi ,
I’m not sure but…
I think it could be because they missed some codecs..
They are for QT, but when you install QT, they doesn’t come with…Last week, I have losted some of those QT codecs comming from a
blackmagic download…and QT was not able to read them anymore (but still read my DV-NTSC cxapture)So they could try to download some on http://www.blackmagicdesign.com
or http://www.digitalvoodoo.netit’s free and as well as it’s a apple codec…you’ll be alright, a technicien from blackmagic told me.
so,
I did it and I got some uncompressed 10-bit 4:2:2 (and 8-bit) codecs
and now QT can read my uncompressed capture.Just be caraful to download the one for your system…
and if the wright one is not in the list, then ask for your type in the search list…they have a lots of free download…good luck

Nope
the Uncompressed codec from apple does not install as part of QT7 you need to load FCP.Save the files as Animation codec and they will be able to read them.

Once again, thank you all for the quick responses!
I had already decided to try exporting using the animation codec, and then I read Gary’s suggestion, so I’ll try that experiment.
I’m still a bit confused about it all, I must admit. Is there a “generic” QT uncompressed codec? Or are all uncompressed codecs proprietary, i.e Black Magic, Aja, etc.
And if there is such a beast, is it true that one only has access to it through FCP?

There may be some proprietary codecs from BMD, but as far as I can tell with my Kona 2 system, they’re using the generic Apple codecs except for the AJA 2Vuy codec. You don’t need FCP to play a proprietary codec as they are installed into the Quicktime folder so as long as the codec is installed in the end user’s Quicktime folder, they can play it.

Both Aja and Black Magic used to use the Black Magic codecs and drivers. Now Aja uses it’s own drivers and the Apple Uncompressed QT, except for HD where they use their own codecs. BM still uses their own codecs as far as I know.
best,

Hmm, this still seems to make no sense to me. If, as the last two posters have said, BlackMagic and Aja are using “generic” apple qt uncompressed codecs, why would my co-workers not be able to view the files with Quicktime Player?
Are these generic Apple QT uncompressed codecs NOT included with QT? Do they have to be installed separately?

correct.
