opendir has moved servers and i cant be assed to reconfigure the clusterfuck that is Histoire, enjoy the new look!
if you're missing any directory headers or footers then try with these: header / footer
LZOcodec is a windows codec. It makes a lossless (or almost lossless) video compression with three steps, first converts RGB information to 4:2:2 (a little bit lossy) then makes a compression algorithm of my own, and last uses LZO algorithm to compress the information.
And as the third compression algoritm you can use to a mixture of gzip and Range Coder.
Well, you can use it as capture codec like Huffyuv or LOCOcodec if you have a fast computer. But the main use I can think is to compress computer generated videos (or animation movies). If you think about it you can use for:
Yes, of course you can. But do not expect too much performance.
Well, if you like "Camstudio losless codec" you will probably know that
this kind of codecs compress every frame without take care of previous one.
But LZOcodec uses previous one in order to compress much more.
So If you like "Camstudio lossless codec" you will love LZOcodec!
LZOCodec v0.3 supports (according with my test with VirtualDub 1.6.14):
Download it from here.
Unzip it!
Simply make a "right click" on the file "LZOcodec.inf" and then a "left
click" on "install".
This software is provided as-is and there is no type of waranty.

| MSU 1.1 (without detecting fades) | 586 KB | 3 min 55 sec | 67,5 MB | 4 min 16 sec | 88,6 MB | |
| MSU 1.1 (detecting fades) | 588 KB | 4 min 20 sec | 63,2 MB | 7 min 26 sec | 88,6 MB | |
| LZOCodec (Gzip || RangeCoder 15%) | 3,19 MB | 10 min 51 sec | 83,1 MB | 14 min 38 sec | 49,4 MB | |
| LZOCodec (Gzip || RangeCoder 99%) | 3,19 MB | 13 min 50 sec | 80,3 MB | 16 min 23 sec | 50,6 MB | |
| LZOCodec (LZO) | 4,95 MB | 13 min 07 sec | 120 MB | 8 min 10 seg | 93,7 MB | |
| LZOCodec (Gzip || RangeCoder 01%) | 9.61 MB | 12 min 20 sec | 99,7 MB | 7 min 09 seg | 50,8 MB | |
| CamStudio (Gzip -9) | 16,5 MB | 16 min 03 sec | 135 MB | 15 min 58 sec | 82,0 MB | |
| CamStudio (LZO) | 63,5 MB | 7 min 51 sec | 234 MB | 4 min 07 sec | 132 MB | |
So I think that is proved that LZOCodec is better than CamStudio. And MSU Screen Capture Codec is the best for movies with low color frames.
But if you want to compress real video movies you will probably prefer to use other codecs. But in this particular test LZOCodec has better compression that LOCO Codec.
