I usually render CF AVI but recently I playing around and try to render CF to quick time and the resulting video is up side down. I am curious anyone encounter this problem or its just me. In post I can flip it it but when view on computer screen the up side down is annoying.

Using what tool(s)?

What I meant was in post, I import the rendered CF moive file onto (Vegas) I can go to pan/crop and flip the video and re-render to avi or any other format. If I choose to rendered CF movie file and the video become upside down. Hope you understand what I am saying.

This is why we have support, to avoid the 20 questions. What version of Vegas? What version of CineForm? Which CineForm product?
