FCP to AE to FCP ;-)
Hi everyone,
just got my new Kona LHe Card and did some tests with it. So far everything works fine but I got a couple of questions regarding the way from Final Cut Pro to After Effects and back to Final Cut:
1) I captured some footage from Digibeta in FCP in 10 Bit uncompressed. I exported for AE with the actual settings. Imported in AE and I got a gamma shift. I have to check the “Match quicktime legacy…” option in the project settings to get the same gamma as in FCP…why?
2) Then I render my footage again in AE using the AJAv210 codec. Back in FCP the footage looks worse compared to the original clip in FCP because it’s blurry. I’ve tested all other codecs but get the same blurry picture (or gamma shifts using Animation Codec or 8-Bit Codecs). What am I doing wrong?

This is a long documented RGB to YUV shift.

Hi Walter,
yeah I know (somehow).
Point 2 is more important to me…
Thanks!

there’s no reason for your footage to come back blurry so long as you are working in exactly the same type of comp as the original footage and you render back to the exact same type of footage from AE.
No reason to use any codec other than the original.
The Gamma shift we just deal with quite simply with filtering.

Ok – I will try again…using different footage and keeping 10-Bit codec all the way.

Sorry – what do you mean?

You either apply a filter in AE or FCP to compensate for the shift.

Yes. That’s what I used to do before the Kona Card. I applied Levels effect in AE with a correction to the gamma but didn’t find this very handy in use. So I’m glad now that I can go from FCP to AE and back to FCP without any gamma shift.
Do you filter the gamma shift all the time?

nope.

Hi Bill,
Maybe you’ve already checked this but one thing to make sure is that the ‘Field Render’ in the Render Settings matches the Field Type of your footage. I’ve seen blurry renders of interlaced footage because the ‘Field Render’ was set to ‘Off’ when it should have been ‘Upper Field First’.
Cheers,

Okay, if you don’t need to use the v210 codec, I suggest the following:
Quit all open video programs.
Go to your Hard Drive > Library > Quicktime folder and move the AJAUNcompressedcodec.component to your desktop.
Launch AE. TUrn off all color management and uncheck the ‘Use Legacy QT …”.
Render.
This should result in a near perfect match accept if you have any out of range clips, they will get clamped to to the RGB being 16-235 only. If you have legacy clips in the v210 codec, this can also cause problems as the codec is now deactivated.

OR lower field depending on what you’re doing and the format you’re delivering to.
AE always defaults to Off for field render.
