I have videos recorded by a camcorder in AVI format. The camcorder came with ArcSoft editing software, which works, but will not let me capture stills from the videos. What can be done about that?
If the player you're using does not have support for image capturing then you can use VLC. It allows you to capture or create images from multiple scenes. VLC is a free product and has embedded codecs which make playback easier for certain file types. You can find the option for screen capturing using Video > Take Snapshot.
