To all users of JVID effects released sofar (A thru I).
The versions released in the original thread do not handle the possibility to have an output image size different from the default (for instance: 0 to have the same as the source).
Here a package with all those versions amended (you can now indicate "0" as width+height and get the final outcome in the original size of the source).

Thanks Dinasset, have a good day !

Thanks Lula, you too !

A warning (valid also for the users of the previous versions):
If you define and use a personal frame for Effects B and B2, it must have a central area black, which the filter interprets as "where the image should appear".
If not you may get an abnormal end of the filter(s).

Many thanks to Lula, who has detected this problem
