Unfortunately, the Java Media Framework (the library ViPER uses to
display (some) AVIs) doesn't allow frame-accurate scrubbing of AVI
files, so they aren't fully supported within the program.
I'd recommend saving the video file in another format that ViPER can
read, such as MPEG-1 or 2, or a folder full of numbered jpegs.
To get the image sequence, open the file in VirtualDub[1], then
select, from the menu, File > Export > Image Sequence... and export it
to a new directory. Then, within ViPER, select Media > Add Directory
as Single File...
To convert to an MPEG, use VLC[2] to open the file, selecting the
'Stream/Save' option to save to a file using the 'Advanced > settings'
in the file dialog. Make sure to select MPEG 1 and mp1v as your
encapsulating and video transcoding options. The mpeg will save a lot
of disk space, but you might lose a couple of frames at the end. If I
remember correctly that VLC's encoder has a bug (or viper's decoder
does, I'm not entirely sure).
