New site? Maybe some day.
|
I have a folder filled with AVIs of silent hill (I cut them into pieces). It's about a gigworth.
Mark Richards is going to crop the video files for me on his mac and send them back to me.
I want the folder to be able to upload and download as much as possible so I need alot of compression.
What should I compress it as? after I compress a 1024 gig file with a .zip, it's still a massive 1022 megabytes, so I'm probably not going to .zip it.
I have RAR, stuffit, Ace, 7zip, power archiver, and a few others |

you will gain nothing out of zipping them or raring them.
or zipping and rarring.
if you know how cmpression on binary files works, you don't get more that 1-3%regularly. |

Well write me a perscription than Doctor Aaron, this isn't my field of knowledge at all. |

what's do you mean "crop the video files"?
why don't you just do whatever it is that you are talking about??
the main way that compression algorithms work are chunking up a file into x bytes and then making a tree structure out of it.
say my file is contains
ABCCAAAZ
in a simple zip, I would take and count them up
A =4
C = 2
B = 1
Z = 1
I make a binary tree out of it. there are more A's so that is the first element
0/\1
A_/\1
_C_/\1
__B_/\1
___Z_/\1
I make some sort of info header for that tree. and then I compress the file so ABCCAAAZ (where each letter is 0-255 ASCII value)
HEX:414243434141415A
binary:0100000101000010010000110100001101000001010000010100000101011010
becomes
LRRLRLRLLLLLRRRL or in binary
011010100001110
HEX: 6A
in my little algorithm there, I took:
0100000101000010010000110100001101000001010000010100000101011010
and translated it into
<header>011010100001110 |
|
why doesn't this work in binary files? cause if you chunk off all the bytes, there is a wider range of bits patterns in the file. this means that the header will be huge and the tree will be huge, negating it's effectiveness. |
|
The video is wide screen and there's a small watermark on the border between the actual video and bottom black bar. it cuts into the video just a tiny bit, so I want to actually crop out the widescreen bars of the video.
I can't crop the video files with any video software I have an I'm not willing to pay a few hundred buts for something that can. I can't even find a program with a cropping feature to bootleg.
Even if I did have said program, I probly wouldn't be able to load more than a 20 minute AVI.

but mark can magically do this?
weird. |
