FCP targa sequence

[Slika Ton]

Why is AE or Motion better at exporting image sequences than a QT? Aren’t all of them based on QT anyway?

[Jeremy Garchow]

QT Conversion seems to do weird stuff with gamma, quality and bit depth. Not all exporters are created equal, unfortunately.

Yes, I’ve seen weird stuff, but I was under impression that same problems happen in AE and Motion as well, as they also use QT infrastructure for conversion…

Other thing is, I’m not sure anymore what a proper functioning combination of OS, FCP, QT, Kona driver is? Is there a “magic combination” that don’t make gamma shifts and other problems right now? I had green flashes with prores hq codec in hd with Aja Kona LHe, and when I updated OS and QT green flashes mostly disappeared but gamma shifts are much more present and noticeable.

I’m currently on a OS 10.5.6 QT 7.5.5 FCP 6.0.5 , kona 6.0.1… Would QT 7.6 and kona 6.0.2 improve things or make it more complicated? Or should I wipe of HD and start from scratch?

Most of the users of AE, Shake, etc use still sequences instead of movies.
Those applications offers more options for managing stills sequences.
FC don’t understand about much about sequences.
However you can export the TGA sequence from the time-line with Export to QT (no QT Conversion).
May work better.

I have also found that FCP likes PNG sequences better than Targas.

Not really.

[Slika Ton] ” Is there a “magic combination” that don’t make gamma shifts and other problems right now?”

Where are you seeing gamma shifts?

[Slika Ton]

In roundtriping to AE in the first place. Even in compressor when making mpeg 2 and some other files.

What bugs me is the fact that everything was near perfect with FCP 5.1.4 and AE and QT of that era. So that just shows that it can be done.

I know that there are workarounds with image sequences but that really makes the whole process more cumbersome and defies the purpose of QT movies as most convenient and fastest way of transferring and shuttling video around. And it used to work very well two years ago, too.

[Jeremy Garchow]

First, quit everything. Then, try removing the AJAUncompressedcodec.component from your HardDrive > Library > Quicktime folder. Then launch AE and try again with all color management off.

I removed AJAUncompressedcodec.component and first results look promising.
I’ll play with it more tomorrow but so far 10 bit material looks as it is supposed to be.

Do I need AJAUncompressedcodec.component at some point or can I just leave it in the closet?

Thank You Jeremy for the help.

[Jeremy Garchow]

You can leave it in the closet as long as you don’t have nay legacy projects that used the AJA UC codec. I just put everything I don’t need in a folder called “Quicktime (disabled)” right next to the Quicktime folder. If I do need it, I simply move them from the disabled folder to the other folder. If you haven’t used AJA 2vuy in the past, you don’t need it now as the Apple UC codecs have been properly updated.
