Rendering in QC I have been running some tests playing back full screen video in QC and fullscreen video in Quicktime and there seems to be a slight loss in quality playing back the video in QC. I have tested Vades movie player and the standard QC patch I have used a sprite as well as a billboard and nothing seems to fix or change the problem. I have tried a number of different codecs and all with the same results. The issue seems to be in the shadows and dark details and I was wondering if QC and quicktime ran with different gammas or possibly colour depth. So has anyone else noticed this and is there away around this. Cheers Steve

interesting, i never noticed this issue with photo-jpeg codec on a gma950 based macbook. Did you try the Disable Color Correction checkbox inside the QC movie loader's inspector panel?
Are you using a billboard on pixel aligned and/or are you changing the aspect ratio or slight elements of sizing in anyway? What are the settings on the actual movie player?
You might play with the "enable clean aperture" and "disable color correction". I've never done a true invert test to see what the visual "crud" is in difference between those modes, but I do note many times when disabling color correction seems "right" on a gut level, and looks better.
I just did a test with my latest v002 Movie Player (you can find it on http://002.vade.info/downloads/beta/v002%20MoviePlayer.plugin.zip ) It has a working color correction option (a long with a lot of other new features).
With "Color Correct" set to true, the video output of my AIC movie is indistinguishable from Quicktime players output, and Apples native movie loader patch. In fact, I cant see a difference between any of them what so ever. With Color Correct disabled you can get a slight speed boost for larger movies (1080 +) at the expense of a slight color shift.
This leads me to wonder; do you have Final Cut Pro installed? If so, do you have the "Enable FCP Studio Color Compatibility" turned on in Quicktime Player preferences? This makes Quicktime Player use FCPs display path and not Color Sync, which QC and friends all use, and you will definitely see a color shift between the two.
If not, have you played with the private settings and disabled color correction for Core Image ("uncorrectedCoreImage")?
wow, good to know this!
Wow... and look at that "use high-quality video setting when available". Geez, I never took note of that.
