Need Suggestion gamma shift color correction

[Aaron Neitz]

You’re using Encore to create you DVD’s, correct?

What codec are you editing in?

Have you tried using iDVD as a test to see if you have gamma shift with that?

Are you watching these finished DVD’s on a calibrated monitor that’s in line with your broadcast monitor?

yes, using AJA Kona LHE with output to broadcast monitor.
remember my source is great. problem is when mastering to dvd in sd or hd bd.

I’m trying to find out where your gamma problems are happening. That’s why I’m suggesting these things.

how are you creating your mpeg-2 streams or h.264 streams?

When you’ve burned this DVD, where are you watching it? Are you watching it on the same television that you’re editing on? Are you watching it on the computer monitor? Are you comparing the mpeg-2 stream on the computer monitor to the burned dvd?

You should not be having gamma shifts. We just need to find the one small step where things are going blooey.

Gamma shifts were a problem with earlier versions of Compressor. Which version are you using?

– gamma problem when output to dvd mastering dvd studio/ encore.
– step. editing on fcp – output to quicktime – compression to mpeg2 dvd spec. – import to dvd studio – mastering dvd.

how are you creating your mpeg-2 streams or h.264 streams?
– apple compression 2.0 for mpeg-2

When you’ve burned this DVD, where are you watching it?
– watching on consumer tv or client tv.

Are you comparing the mpeg-2 stream on the computer monitor to the burned dvd?
– I’m comparing the dvd with my timeline source and my original source from tape.

-when i said gamma shifts. the video of the dvd is alittle darker then my timeline video or my original source. correct me if i wrong.
I thought wrong you see in the timeline of fcp is what you get in the final dvd mastering.?

I using 2.0 compressor. but if i try to import the quicktime for my fcp to encore it still have same problem. i let encore cs3 transcode my quicktime to mpeg2 stream for dvd.

You are editing in h264? That could be your problem.

Also, are you sure that your DVD player isn’t adding setup to the image? Could be a ‘gamma shift’ of sorts but not really, you mentioned in an earlier post that it looked like watching your prgram though a glass of milk which could be setup. What kind of tv do you have and how is it hooked up?

[Aaron Neitz]

Do this for me:

Export video to QT on your desktop.
Use Compressor to create MPEG-2 (.m2v)

Open original QT in QT player
Open MPEG-2 file in QT player

Is the MPEG-2 darker between the 2 Quicktime Player windows?
