As for me it’s clear using “Render As…” there you can check “Stretch video to fill output frame size” which helps much by resizing. This function doesn’t work with “Batch Render” script.
Today I use the MikeCrash’s plug-in “Auto Levels” on the video bus and find out that these 2 render methods make quite different results by wmv format.
Has somebody noticed it and, is there also any Sony plug-ins doing such differences? Can I avoid this phenomena?
