Weird anamoly with the above (excellent) guide that has worked for me in the past.
Trying to spin some anamorphic magic and using the above calculations - first virtualdubmod won't allow the NTSC crop setting that is given above, gives an error of:
"Cannot use crop to enlarge or shift a clip" after I save the AVS Script
(and then if I leave the crop figures untouched - it throws up the following: "Couldn't locate decompressor for YV12"
Ignoring the above and processing regardless - TMPGenc then says "can't open or unsupported" with the final avi.
It's the last step and it's becoming frustrating !!
Original source material is NTSC 4:3 352x480
Many thanks if you can shed any light or where I'm going wrong or what seems the stranger issue !
