Audio is fine but no video visible

Hi, I downloaded Shotcut v17.02.05 for Windows 7 and opened an MP4 video file. But, in Shotcut, only the audio is present - there is no video, just a large green rectangle where the video images should be displayed. The video file and others like it play perfectly in my media players and can be edited in other video editors such as NCH VideoPad. Any ideas how to get rid of the green rectangle and instead show the actual video images in Shotcut? I tried both the 64-bit and 32-bit Windows 7 downloads. Thanks.

Your system’s graphics is incompatible with Shotcut’s usage of OpenGL. You can try to change Settings > Display Mode to DirectX, restart, and see if it works.
