do you divide by the factor .98 or divide by .98?
i'm encoding a movie called ginger snaps. so after you do
frames/movie length/24 *sample size, do you divide by the factor .98 or divide by .98? |
Hi Paul0889,
You multiply the sample file size by .98 The formula would read like this: MPEG size = ((Total frames/MovieTimeInMinutes)/24) * MPEG sample file size * .98 -kwag |
so then when you predict you sample size, your going to have to guess something a little higher right? See my predicted sample size is 11.63 but if i multiply by .98, it doesn't come out to 727.9, the amount of disk space left. So i have to raise the sample size a little higher right?

When you get your predicted sample size of ~11.63, multiply it by .98 and multiply by 60 ( if you're encoding at 23.976 ) and that will be your actual final file size. :wink: Edit: Actually just multiply your estimated sample file size (11.63) by .98 and by 60 and that's your final file size. -kwag |
what if i'm encoding at 25fps? would i still multiply by 60? Also, since i multiply by 0.98 and 60, i'd have to pick a higher sample size since
11.63*.98*60=684. So then i'd have to raise the sample size to about 12.35 in order to get it equal to 727.9 right? |

Now you can multiply by 60, because the Sampler is talking 25 frames every minute, and the GOP size is also 25. Give that a shot. It makes the calculations much easier. Just (CD Size - audio size) / 60 = your sample size. Example: ( 800 - 100 ) / 60 where 800 is CD size and 100 is audio size :wink: -kwag |
