MAC / CS3 / DVCPRO-HD color shifting

[Mark Hatch]

That is very interesting. I didn’t even know that the Dumpster program existed. I took raw DVCPRO HD footage and imported it into both FCP and AE CS3. I then exported that footage from AE, unaffected, in the DVCPRO HD codec. I noticed that gamma flag that AE adds and it read 2.2. I then imported that footage from AE into FCP and laid it over the original. There was an obvious shift.

I then changed the gamma in dumpster several times and reimported it into FCP and laid it over the original footage. I never got it to match up very well. At this point, though, I can’t remember if it is correct to apply any color management in AE. Can someone remind me what was determined for that? Do we interpret the footage differently than default in AE CS3?

Thanks.

If you go to the Project Settings in AE you can change the Color Settings but I still haven’t found a combination that works.

I need a MAC guy to post 2 huge dvcpro hd single frames from Color_Card.tif before and after AE import back to FCP again to compare the quality.

I can then program a new ICC color management profile then you can use AE’s color converter to always make AE work with FCP.

Count me in. I’ve got the same problem as described in this post. Here are my specifics:

Powermac G5
OS 10.4.11
FCP 6.0.4
AE CS3
AJA KONA LHe
DVCPRO 720p24

I’ll try running a test by converting the DVCPROHD footage to PRORES first then do a round trip….I’ll report back.

Chris;

The files you requested are attached to the bottom of this Google page:

We have been struggling with this issue as well and have kept a close eye on this thread. Our intended work flow was explained in great detail to Mac’s Pro Apps support. We are still waiting on an answer that works.

Good luck and let me know if you need any other tests files.

Same trouble here. It was fine a week ago, then I upgraded to QT 7.5 and it was broken. However, a neighboring system is nearly indentical to mine and it does not have this issue.

I’m considering purchasing either a Panasonic DVCPRO HD-based camera or a Sony XDCAM EX-based camera. This monumental thread has scared me about DVCPRO HD to say the least. I’m leaning toward the Sony EX1 for this and other reasons, but the long GOP codec apparently has its own problems too.

Any workflow-related comments regarding XDCAM EX footage in AE would be great. I use FCP to edit, but AE is my main app overall. I won’t even consider a format that doesn’t work well in AE.

Any rumors the new CS4 AE will resolve the problems described above? I certainly hope so. Thanks a lot, Brian

I see this is still gone unanswered. I just realized how big the issue is tonight.

I have been working a lot with RED R3D files that have been exported through RED ALERT as PRORES422HQ files. I edit in FCP and then export as PRORES to AE. HUGE shift. This is totally unacceptable. I can’t believe either side of the equation (Apple or Adobe) hasn’t dealt with it yet. That shift is keeping us from effectively replacing a transfer house for final color correction.

Just to keep you up to date… A year have passed and I Still have not found a straight workaraoud for the colorspace/codec gamma/color shift. And now, reading the comment from the “red” user above, things gets complicated for me, as I plan to have a RED in the future…

And for you that find unbeliavable that apple/adobe/panasonic/aja/whoever doesn’t take apropriate measures to fix this, please write for them, tell our cases, tell we do everything written in that “color space conversion” tech papers they publish and had no success.

I have an idea. Try the SHEER video codec. SHHER is known for it’s very accurate color space conversion. Maybe you load up the SHEER codec and TRANSCODE to SHEER then go back and forth to and from AE.

It’s worth a try.
