WHAT FUCKING SHIT IS THIS?

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 a character compression algorithm to compress the information.

And as the third compression algoritm you can use:

LZO: Faster one (recommended for capture)
Gzip || Range Coder: slower (recommended for store)
RTPPM: slower (recommended for store)

WHAT IS IT USEFULL FOR?

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:

Capture your screen as an avi
Convert a SWF (flash file) to an avi
Convert a Power Point file to an avi
...

CAN I USE IT FOR REAL VIDEO?

Yes, of course you can. But do not expect too much performance.

WHY MUST I USE IT?

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!

WHAT COLOURSPACES ARE SUPPORTED?

LZOCodec v0.4 supports (according with my test with VirtualDub 1.6.14):

RGB32
RGB24
RGB16 (555)
RGB16 (565)
YUY2
UYVY
YUV16
YUV12 NOT recommended! Lossy format!

LZOCODEC IS VERY BAD WHEN CODING YUV12 VIDEO. WHY?

I will expain it once more. YUV12 is only for compatibilty reasons.
All video formats are converted to YUY2 and then the YUY2 video is coded.
I will repeat it. The internal compression algorithm only works with YUY2 video. So all different colourspaces are converted to YUY2 before coding.

WHAT IS RTPPM?

Is a compression algorithm that I have developed and I have called it "Real Time Prediction by Partial Match".
When It compresses the video stream which comes out of the second compression algorithm is archives a compression ratio similar to bzip2 algorithm. But for text or normal binary files it compression ratio is much worse :(

IS LZOCODEC v0.4 FASTER THAN v0.3?

I think so. I have moved to Microsoft Visual C++ Express, and it optimizes more the generated code. But It don't have resource files editing :(

DO I NEED A CRACK IN ORDER TO USE LZOCODEC?

NO

LZOCodec is a totaly free codec. In fact is a experimental one.

INSTALATION:

Download it from here.
Unzip it!
Simply make a "right click" on the file "LZOcodec.inf" and then a "left click" on "install".

COMPARATIVE CHART:

	Screen Capture Test		Flash Conversion Test		Real Video Test
Codec	Size	Time	Size	Time	Size
MSU 1.1	663952 Bytes	1m 50 s	80 MB	9m 10s	73 MB
LZOCodec (LZO and NO keyframes)	1277158 Bytes	4m 45s	120 MB	6m 55s	58 MB
LZOCodec (gzip \|\| Range Coder 15% and NO keyframes)	1293580 Bytes	5m 25s	84 MB	19m 47s	39 MB
LZOCodec (RTPPM)	948224 Bytes	4m 6s	83 MB	4m 39 s	37 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.
