QT Apple Codec Problem on PC
To my knowledge, this problem began yesterday. When trying to open several clips captured by DV Rack, using its generic QT setting (DV/DVCPRO NTSC), Quicktime inexplicably masked 75% of the image, meaning, if you were to divide the screen into quadrants, only the upper left-hand quardrant displays. When you initially double-click the file, you momentarily see the full image, then it's masked. I can save these clips in another codec (Avid DV, Meridian Compressed, H.264, or even another format, AVI, etc) and they play (display) normal. I thought DV Rack had to be the culprit. Then I opened other generic Apple DV/DVPRO NTSC QT's and they only showed upper left-hand. You can cntrl-shift-f and choose current size and QT will display the full image; you can simply save a qt ref and everything displays fine. These clips load into FCP and Avid no problem. Under Quicktime Preferences, I unchecked "Show High Quality Video When Available;" I reopened one of the clips in question and got full image, but dreadful quality. In the event it's not an issue with my video card (an ATI Radeon Xpress, but has plenty of OpenGL and other bells and whistles), I thought I'd asks some Mac users if they've encountered this issue when dealing with PC's. Also, yesterday I was using QT Pro v 7.1.3; this morning upgraded to v 7.1.6, no change in behavior. Thanks.
