Hey Adam,

this works fine for me!

Thank you again for taking the time…

Bill

Adam,

great tip! Thank you so much for this.

Problem is that I can’t keep up my intended layout of the letters, because when I use the inheritance effector in conjunction with the Matrix object, the letters move to the positions of the clones of the Matrix Object. Then I’m only able to edit the position of the letters by changing the X,Y,Z parameters of the Matrix Object…but that won’t give me the perfect result.

Do you understand my problem? But again – thanks for your time answering to this…helped me a lot so far!

Bill

Hi Bruce,

thanks for your hints…I already tried most of them. The problem seems to me more like a bug or something…cause the problem is not that my objects not doing exactly what I want, but they are jumping very energetic to the left for no reason. Did you watch the short movie-clip I attached? There you can see that they jump to the left, as if a force is dragging them into that direction.

I hoped that someone else made this experience and could find a solution for this unexpected behaviour.

One other thing that I discovered is that when I change the collision-type to “ellipsoid”, my letters jump correctly into the air…changing it back to “automatic” or “box” makes them jump to the left again. I worked out a solution for me by keyframing the collision-type…so one or two frames after the bouncing from the floor, I change the collision type to “box”. But…I HATE workarounds! 😉

[Bill Nelson]

Hooray! Found the solution! Thank you!!!

To test my problem I created a normal DV-PAL Composition and added a 50% grey solid. My waveform displayed me a solid line at about 60% – the gamma shift.

Then I changed to the AJA Control Panel and left ColorSpace untouched set to “Auto”. I changed Gamma to Linear (1.8) and bang! – my line just sits perfectly on 50%.

Now I only have to learn about Gamma stuff again, because I don’t understand in detail why I have to select 1.8. I always thought of video with a gamma of 2,2.

Thank you guys!

So no matter what, your renders are now coming out gamma shift free, but in oder to get the proper preview out of AE, you need to enable the use legacy gamma?

Correct!

Try capturing a new clip as a test with this current setup and see if that’s still true.

Yes. 🙁

If you can, would you care to upload a few frames of your video so we can see the same thing?

Although I think that you won’t see a problem with this file, because it seems to be more a problem with my AE or Quicktime. I don’t know! 🙁

[Bill Nelson]

Jeremy – sorry for my bad english. Maybe it’s confusing you. So again:

When I import my Footage to AE and compare the clip to the same footage in FCP, I SEE a gamma shift on my waveform monitor. Means – my clip in FCP is darker than the clip in AE. The funny thing is; when I render my clip in AE and import it into FCP – the gamma is correct.

But when I turn ON the legacy-option the preview in AE works also correct. Means – I can’t see a difference in gamma on my waveform comparing FCP and AE.

Do you get me?

I just would like to know why I still have to check the legacy-option to put out a correct signal over the AJA card.

[Bill Nelson]

Perfect.

Okay, so NOW you should start AE, turn off the use legacy and color management, and render. Your footage should now match your source.

Jeremy

The render works fine. No gamma shift. But within the AE application I see the gamma shift when I DON’T check the “legacy” option.

[Bill Nelson]

I closed AE and FCP, removed the codec and started the apps again. Do I have to restart the Mac?

I’m using AE CS4 on a quad core mac with OS 10.5.6

[Bill Nelson]

Hm, removed the codec but still get the shift.

[Bill Nelson]

Launch AE. TUrn off all color management and uncheck the ‘Use Legacy QT …”.

When I do so I get the gamma shift on my screen and on the waveform monitor.
