http://cloanto.com/users/mcb/19950127giflzw.html its a matter of both companies I guess.. neither here nor there I suppose..point is..even though avi will be more time consuming..the final results will still be better than importing lossy compressed formats similar to differences between wav and MP3.. or oranges and orange juice.. or, or, or.. lol another was the flc/fli animation from autodesk..anybody remember that one? and..you could always just go ask e-frontier why But I assume robo is more interested in reducing rendering time than the history of gif..so how bout we get back to him..after all it's his topic..carry on :)
