Need someone good in math...

Hi. I need to figure out how much space will a 1 minute video take up.

Here are the figures:
The video lasts 00:01:24 and has a size of 24.5 Megabytes. If I make a video that has a duration of 1 minute, how much space will it take up?

About 17.5mb? My math is terrible as well.

dont you think that you should do your homework?

hint: count the number of seconds, that count what is 1 sec in MB, than multiply it x60

Than is a word that compares 2 things to eachother, then is the word you want.

Not counting the overheads (e.g. "magic numbers" indicate the particular video format), I'd concur.

Hint: the source video is 84 seconds long, and you want it to be 60 seconds. The file size will change in a similar proportion, 60 eight-fourths of the original.

17.5mb is the right ratio, that doesn't mean the file will actually be that size though.

I lovez peoples that check otherz grammer it really helps us to improve our grammer in are posts so others understand us they really can't not otherwise.

Edit: Good I was mainly correct. You would need a flat bitrate and what was said above to predict the exact size.

I'll recheck with the calculator:
Convert 1 minute 24 seconds to seconds: 84 seconds

84 seconds divided by 24.5 Megabytes gives how many seconds for 1 Megabyte: 3.428571429...

Seconds per Megabyte times 17.5 Megabytes = Exactly 60 seconds!

Thanks!

I lovez peoples that check otherz grammer(add Period, to prevent run-on sentence.) it really helps us to improve our grammer in are posts so others understand us(.) (T)hey really can't not otherwise.

People is plural.
grammar,
again grammar,
our,
either change can't into can, and combine can and not, or remove not.

See corrections.
:p

The 17.5 is only approximate. Most of the video files I've worked with have some extra information stored in them to tell the player what format they're in, e.g. NTSC or PAL (this is just an example), number of channels for the soundtrack, frame rate, stuff like that which could throw the calculations out slightly.

I was mainly going for run-on sentence with that one. Thanks dragos! ;)

The reason that works is because we have fixed rules for spelling and grammar.
