I am very new to VEM. I am trying to create a highlight video of my son playing lacrosse from game footage supplied by his coach. The source video is a DVD.
I've converted a .vob file from the source DVD to an .avi file using VEM. I then open the .avi file in VEM and add it to the timeline. The beginning frame of the video shows in the Preview window. However, when I click the play button in the Preview window I hear the audio playing but the video does not change - except about every 10 seconds. When it changes it stays on that frame until it changes again. The slider line advances in the timeline window as I would expect.
Why doesn't the video play properly in the Preview window?
What am I doing wrong?
Thanks for your help.

A DVD-video is in the MPEG-2 format and typically has a resolution of 640 x 480 pixels. MPEG-2 files are highly compressed. Editing this type of video is very CPU-intensive. To achieve real-time editing and previewing, the timeline will therefore skip frames. Fortunately, this only happens while previewing the timeline. After editing, you can make movie and get a video without any skipped frames.
Two things can improve the preview's performance. You can reduce the project dimension to 320 x 240 pixels and later choose to make the movie in a higher dimension. You can also convert the DVD video to an intermediate AVI file for editing.
