### What about 1080p?

**Fri Feb 06, 2009 12:27 pm**Hey Luvpeaceguru,

Thanks for reading my post.

I had a thought while writing your reply. If 720p is 1280 * 720 = 921600, and 1080p is 1920 * 1080 = 2073600,

then 2073600 divided by 921600 = 2.25. Therefore 1080p is 2.25 times larger than 720p. So if we carried this

over to optimal output sizes, a movie length of less than 2.5hrs at 1080p would be 4485.12 * 2.25 = 10091.52MB, = 9.855GB or ~10GB.

A movie length of greater than 2.5hrs would result in 6.57GB * 1024 = 6727.68MB * 2.25 = 15137.28MB, = 14.7825GB or ~15GB.

Ok you would need to follow the instructions up until 'Step 18', where you set the resolution. Set this to

'1920x1080'. Follow 'Step 19', but your calculations would be as follows:

10GB * 1024 = 1024MB. You would now divide 1024 by the movie length in minutes. Use my example of 131.25

you would calculate as follows: divide 1024 by 131.25 = 78, which is for 1min, so now we multiple 78 by 5 = 390MB.

15GB * 1024 = 15360MB. You would now divide 15360 by the movie length in minutes. Use my example

of 131.25 you would calculate as follows: divide 15360 by 131.25 = 117, which is for 1min, so now we multiple

117 by 5 = 585MB.

Continue with the steps but substitute 170.85MB in my example with the result you got using the above calculation.

Desired output movie size of length less than 2.5hrs at 1080p = 10GB

Desired output movie size of length greater than 2.5hrs at 1080p = 15GB

There you have it. Good luck and if you could, please let me know how you went and what the quality was like.

If my calculation seem about right I will edit the main post and incorporate this reply?

Good luck

'1920x1080'. Follow 'Step 19', but your calculations would be as follows:

**Movie Length less than 2.5hrs:**10GB * 1024 = 1024MB. You would now divide 1024 by the movie length in minutes. Use my example of 131.25

you would calculate as follows: divide 1024 by 131.25 = 78, which is for 1min, so now we multiple 78 by 5 = 390MB.

**Movie Length greater than 2.5hrs:**15GB * 1024 = 15360MB. You would now divide 15360 by the movie length in minutes. Use my example

of 131.25 you would calculate as follows: divide 15360 by 131.25 = 117, which is for 1min, so now we multiple

**To summarise:**Desired output movie size of length less than 2.5hrs at 1080p = 10GB

Desired output movie size of length greater than 2.5hrs at 1080p = 15GB
