H264 for iPod may be larger than 320 pixels wide
Formula for calculating video size: x=sqrt(76800*r) y=x/r Where This is where I recommend the excellent FormulaCalc widget - the only Dashboard calculator you'll ever need. As to what that looks like on an HD screen, I'll leave that for someone who can afford the hardware to find out :-)
FormulaCalc Issues
I just downloaded FormulaCalc from the German website. But how do you do the square root? I tried X^(1/2) but that only yielded X. In fact how do you do exponents? Because 9^2 yields 11 not 81. It seems like a nice widget but not very powerful if it can't do exponents. Maybe I'm just using old school notation or they use different symbols in Germany.
H264 for iPod may be larger than 320 pixels wide
Obviously video at this size will have to be scaled to play back on the iPod itself. And while the iPod is capable of this video scaling, some people have reported smoother playback of scaled videos when the resolution is evenly divisible by 16. While the original poster's 2.35:1 aspect ratio suggestion of 416x176 fits this suggestion, the formula suggested here does not. |
