I suggest that you purchase a cheap calculator or learn to Run->Calc. The reason that I say this is it is pretty easy to calculate.
Your maximium in the X dimension is 320 pixels and Fab works from that.
If the DVD is 4:3, the resolution should be 320 x 240 (320 divided by 4 multiplied by 3)
If the DVD is 16:9, the resolution should be 320 x 180 (320 divided by 16 multiplied by 9)
What then further confuses the issue are widescreen DVD’s which have an even smaller aspect ratio than 16:9 and you will get a lot of them.
Fab usually makes a pretty good guess at what the resolution should be.
You can then further complicate the issue if you want to crop/resize the movie.
I suggest you take it one step at a time and once you fully understand one, move on to the next.
That’s very informative and you guys are so good…Thank you, love you all.
