<p>1 revision</p> <p><b>New page</b></p><div>=== Function ResizeARC (Aspect Ratio &amp; Compressibility) (from [http://www.doom9.org/index.html?/gknot-basics.htm]) ===<br /> <br /> It&#039;s a bit guesswork as you cannot predict compressibility of your movie but here&#039;s some hints:<br /> <br /> * It&#039;s not a good idea to go below 0.20 bits/(pixel*frame).<br /> <br /> * If you go above ~0.35 you might not be able to reach your desired filesize.<br /> <br /> * If you go for 1 CD stay close to 0.20.<br /> <br /> * If you go for 2 CDs stay around 0.27.<br /> <br /> * If TV bits/(pixel*frame) is below ~0.13 you should raise your bitrate (and go for more CDs).<br /> <br /> This function respects AR (Aspect Ratio) as possible mantaining MOD32 resolutions, uses bitrate, bpp (bits per pixel) and the resize function specified as parameters.<br /> <br /> Usage: ResizeARC(860, 0.2, &quot;FastBilinearResize&quot;)<br /> <br /> function ResizeARC(clip c, int bitrate, float compressibility, string resizefn)<br /> {<br /> ratio = c.width./c.height<br /> res = bitrate*1000./(compressibility*c.framerate)<br /> nhtemp = sqrt(res./ratio)<br /> nwtemp = nhtemp*ratio<br /> nh = nhtemp - nhtemp%32<br /> nw = nwtemp - nwtemp%32<br /> return resizefn(c, nw, nh)<br /> }<br /> <br /> [[Category:Shared functions]]</div>
