Has anyone tested them for the difference ?????. The manual only gives a brief description with some technical details. Check the manual here

What would be beneficial is a comparison of the following

Compression

Speed

Quality

What about testing by yourself ?

Be carefull : I definitely stop using GaussResize as it introduces a LOT of artefacts. Fortunally I did not do too much movie before to see that.

I use Lanczos4.

ha ha....I knew it, well as I was writing this post, it came to my mind that someone will come back and say, "Why dont you do it yourself"......I knew it....................

But I think a test done by one of you experts would carry more weight and following than done by me !!!!!!

If noone has that info.......then probably I might think about doing it myself....................

For quality, okay (and I answered a bit). But speed and compression ? Come on !
