View Animated Sequence File displays the Windows-standard Media Player to view the current preview file.
When you use Create Animated Sequence File, 3ds Max stores the output preview in a file called _scene.avi by default. View Animated Sequence File loads this file. If you want to keep the preview file, use Rename Animated Sequence File to save it under another file name, otherwise, the next Create Animated Sequence File will overwrite _scene.avi.
The Media Player has its own Help system.
