Thumbnail Maker is an Arexx script for ArtEffect 4 from Haage & Partner. 
It uses Ffmpeg to generate a series of frames from a selected video, and 
paste them onto a canvas to create a sequence of thumbnails. Data about 
the video is printed at the top, along with a user-definable string.

I wrote this script for my own use and have decided to share it with
other users. Feel free to modify the script for your own devices. 

This is version 1.01. It fixes a critical bug if the source device name has 
a space.

Requirements
*	ArtEffect Version 4. If you have an assign "ArtEffect:" then it 
	remembers the last location a video is saved from and stores this 
	in ArtEffects Settings directory.
*	FFMpeg. Tested with versions 4.0.2 and 4.2.1 for AmigaOS 4.x. The 
	script checks for Ffmpeg in C directory and will quit if it isn't 
	present.
*	The text printed on the canvas defaults to Verdana 18. The script 
	checks for this in FONTS: and quits if it isn't present. Verdana is 
	part of OS4 system fonts so should be present by default.
	See also BUGS below.
*	Depending upon the size of your video, you may require alot of RAM, 
	hard disk space, and CPU cycles.
*	rexxsupport.library. The script checks for the presence of this and
	quits if it isn't present. It should be part of the standard OS4 
	installation.

As ArtEffect is 68k software, and there exists a 68k version of Ffmpeg, this 
script *might* work on AmigaOS 3.x, but I have only tested it on my X5000.
