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:
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 v0.4 supports (according with my test with VirtualDub 1.6.14):
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.
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 :(
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 :(
Download it from here.
Unzip it!
Simply make a "right click" on the file "LZOcodec.inf" and then a "left
click" on "install".

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.
