Using
- Windows7
- MS Windows 7 Media player
- Sony Movie Studio 12

Problem: Automatic Video thumbnail selection
I think the Windows Media Player selects the thumbnail of the video file is based on about 20 seconds from the beginning of the video. I want to be able to select independently what time/frames of the video is used as the thumbnail image.
I haven't found any way to do that in the Video Player. Changing the images in a video at about 20 seconds is not an option.
Thank you in advance.
