DVD to xvid

[LDanix]

Newbie here.

I can't seem to get my ratios correct.
What is the proper resolution to select to get the full DVD resolution encoded for movies with ratios of 1.85:1 and 2.35:1?
Thanks

The equation is simple. Width / Height = Aspect Ratio.

Therefore Width / Aspect Ratio = Height.

Let's assume Width = 640 pixels. Aspect Ratio is 1.85

640 / 1.85 = 345.945945 etc. Rounding up to the nearest pixel gives 346.

A simple validation by putting 640 x 346 shows an aspect ratio of 1.8497, which is near enough in this instance given the slight rounding we had to do.

Again, Width = 640, Aspect Ratio = 2.35

640 / 2.35 = 272.340. Rounding to nearest whole number gives 60 x 272.

FitCD verifies this to be correct.

If you need a smaller width because you need to use a lower bitrate, recalculate accordingly.
