I'm looking for a way to batch convert a bunch of older PAL Std Def 4:3 720x576i files which have a letterboxed 16:9 image on them (I think the technique was called Mat) to PAL Std Def Anamorphic 16:9 720x576i files - eg I want to crop the top and bottom "black bars" as the problem on my 16:9 TV is these clips have a black border (top, bottom, and sides).

There is a guide here but it https://forum.videohelp.com/topic316902.html but I'm after a way to do a whole heap (eg batch convert) - I'd like to use either a freeware tool or one of my existing editors (Nero 9, VideoStudio11+)

Thanks
Nathan
