If you ecuate the quality factor Qf (bits per pixel) from two movies you have:
Qf = Bitrate1 / (fps1 x height1 x width1) = Bitrate2 / (fps2 x height2 x width2)
With fps1 = fps2 and height2 = AR x width2
Bitrate1 / (height1 x width1) = Bitrate2 / (AR x width2 x width2)
width2 = SQR ( (Bitrate2/Bitrate1) x (height1 x width1) / AR)
If Audio bitrate is reduced also, we can replace Bitrate2/Bitrate1 by Size2/Size1 (more or less)
width2 = SQR ( (300/2000) x (832 x 416) / 2.423) = 146
height2 = 146 x 2.423 = 354
Or maybe better 352 x 144
If you use more high resolution you have less quality

i have tried this resolution even its more worse than before . here is another movie that is encoded by other user. with resoultion of 660*272 it works fine and so smooth .
