Blacks crushed and whites over exposed on FLV from QT
by Alex Bond on Dec 17, 2008 at 3:13:10 pm

Hi,

I've just noticed that on all my recent work that's been compressed from high quality Quicktime movies, using either Riva Encoder or Sorensen with a VP6 plugin, is coming out with higher contrast - blacks crushed and whites over exposed.

Has anyone encountered this and/or found a way round it?

Thanks in advance

Actually I think this is a hardware issue:

I'm using dual monitors, when the QT movie is in the middle of the two ie with half the picture on one monitor and half on the other, the picture is more compressed and hot, if it's on one monitor only the picture looks washed out...

Does that sound like a Graphics card issue?

It sounds like your monitors aren't calibrated. Have you done that?
Apple has a built in calibration tool that will at least get you closer. System Preferences/Hardware/Displays/Color/Calibrate. It's all done by eye, so it's not as accurate as Spyder or similar hardware.
