Movie Studio 17. Window's 10. I rendered videos at 1920 x 1080 and they play properly. I imported them into a new project and the preview window showed the proper source size, but only 960 x 540 preview. Export was also 1/4 size. What have I done wrong?
Thanks for the response. I looked and the size of the rendered mp4s is 1920x1080. I can't understand what I did. However, I tried again by exporting one of the three *.vf files and confirming that it played properly at 1920x1080, then opened a new project with it, added the other two previously rendered files, edited then exported the compilation and the finished video played properly, full screen.
