Fullscreen is the opposite of widescreen and is non-anamorphic
Anamorphic is by definition anamorphic
What you call widescreen was in fact what should be called anamorphic (that is why you had to use source_anamorphic=true in your script).

Widescreen isn't a proper word for video. It is generally used to describe the format of a TV set (widesceen is opposite to 4:3, and it is also called "16:9").

thanx Phil for the quick answer (like always ) so what you are trying to say is
"Gripcrop(352, 240,overscan=1,source_anamorphic=false)"
is 4:3 (full screen) and the size between 4:3 and 16:9 is
"Gripcrop(352, 240,overscan=1,source_anamorphic=true, dest_anamorphic=false)"
correct?

There is no "16:9" size and there is nothing between 4:3 and 16:9 !

There are anamorphic and non anamorphic sources !

DVD can be fullscreen or anamorphic.
Avi are generally non anamorphic (4:3). Some are fullscreen (that means that the dimension have an A/R of 4:3, for instance 640*480) but the majority of them are "4:3 letterboxed" but with the black borders removed ! Like the source you have (and that is what is called "16:9 size" but as you can see, that is a highly confusing word that is better to avoid !)

(almos) ALL AVI MUST BE DONE WITH SOURCE_ANAMORPHIC=FALSE, AND FOR DVD YOU HAVE TO LOOK AT THE BACK COVER TO SEE IF IT IS ANAMORPHIC OR NOT.

Actually, almost all AVIs are 1:1, i.e. square pixels, since they're designed for viewing on a PC monitor. I don't recall ever seeing an AVI with any other pixel aspect ratio.

You're right, I wanted to say that all avi are non anamorphic and I mistaken this with "avi are 4:3" . Fortunally Gripfit takes care of 1:1 A/R also (if I remember well what I saw in your sources).

I've never seen an anamorphic AVI, but I think it's a great idea. At least for transferring onto DVD...

Yep, I believe it does. Anything not one of the standard resolutions (352x240, 352x480, 480x480, 704x480, 720x480, and the similar PAL versions) is considered 1:1 PAR. Or something like that.

1/ you enver see any DV avi outputed from digital camera (some have an anamorphic mode)
2/ you never DLed avi done by a dumb noob with boxing gloves on both hands that did not compensate the A/R of the DVD he ripped

heh yeah I've seen a couple of those. But even then the anamorphic is no good, because the rest of the encode sucks .

after learn with masters i can rewrite the "law":
bad sources takes to bad encodes

(*) bad sources are too : ...done by a dumb noob with boxing gloves on both hands... and similar!

no way out, you only loose time...because the rest of the encode sucks
