Lagarith is a lossless video codec intended for editing and archiving. Lagarith offers better compression than codecs like Huffyuv, Alparysoft, and CorePNG. There are a few lossless codecs that can compress better than Lagarith, such as MSU and FFV1; however Lagarith tends to be faster than these codecs. Lagarith is able to operate in several colorspaces - RGB24, RGB32, RGBA, YUY2, and YV12. For DVD video, the compression is typically only 10-30% better than Huffyuv. However, for high static scenes or highly compressible scenes, Lagarith significantly outperforms Huffyuv.Lagarith is able to outperform Huffyuv due to the fact that it uses a much better compression method. Pixel values are first predicted using median prediction (the same method used when 'Predict Median' is selected in Huffyuv). This results in a much more compressible data stream. In Huffyuv, this byte stream would then be compress using Huffman compression. In Lagarith, the byte stream may be subjected to a modified Run Length Encoding if it will result in better compression. The resulting byte stream from that is then compressed using Arithmetic compression, which, unlike Huffman compression, can average fractional bits per symbol. This allows the compressed size to be very close to the entropy of the data, and is why Lagarith can compress simple frames much better than Huffyuv, and avoid expanding high static video. Additionally, Lagarith has support for null frames; if the previous frame is mathematically identical to the current, the current frame is discarded and the decoder will simply use the previous frame again.
This codec was build using the Huffyuv source as a template, and uses some Huffyuv code, most notably the routine to upsample YUY2 video to RGB and to perform pixel prediction on YUY2 video. Other colorspace conversion routines were taken from AviSynth. Lagarith is released under the GPL.

Bytescout Lossless Video Codec is the free (for non-commercial use) the lossless video compression and decompression video codec for Windows and Windows x64 Free high quality lossless video codec. This codec is intended for lossless video compression (used for saving master copies or intermediate rendering results). Lagarith Lossless Codec: Welcome to my homepage. About Ben Greenwood. I am a software engineer with Alion Science, and work as a contractor at the Crane NSW base. I am also an RIT graduate; I graduated with a BS in Software Engineering in 2007. I enjoy computer programming, particularly programming dealing with computer graphics, image/video.
Thanks to AbsoluteDestiny and Zarxrax for helping with testing the codec, Andrew Dunstan for providing optimized colorspace conversion routines for the X64 build, Ben Rudiak-Gould for developing Huffyuv and AviSynth, and to Avery Lee for helping speed up the decoder as well as having developed VirtualDub.
Version 1.3.20 introduced a new option to prevent upsampling when decoding. Checking this option and having the mode set to RGB or RGBA will prevent Lagarith from performing any colorspace conversions when encoding or decoding video.
Lagarith Installer (v1.3.27) An installer for 32 and 64 bit versions of windows (other than Windows 2000, see below). Thanks to Zarxrax for creating and testing the installer script.

Windows 2000 users: the multi-threading changes introduced in 1.3.24 are not supported in Windows 2000. Dune 3 mac free download. Please use version 1.3.23 instead.
Canon image runner 5055 users manual. CamStudio Lossless Codec was designed specifically for lossless compression of video screen capture (screencasts). It may be used for making software presentations, video lessons and tutorials, recording video from games and can be used in most video recording and editing apps. CamStudio codec allows you to produce crystal clear results with a much smaller file size compared with other more popular codecs, like Microsoft Video 1. Quality of lossless compression makes CamStudio Lossless Codec perfect for use in online video conferencing or webinar applications. It's probably the best technical solution for video tutorials, presentations and instant screen (desktop) sharing. Version 1.5 of CamStudio Lossless Codec it is now 64-bit compatible.
