FM Screen Capture Codec is a very fast, lossless codec. It can operate in 16, 24 and 32 RGB color modes, supports a temporal compression and provides a good compression ratio.
There are two main options: Screen Capture - to compress frames in real time. Recompression - to compress already recorded videos.
Note, this codec is optimized for creating demonstrations and tutorials and works slow on real videos. For example, it is very fast on office applications (Word, Excel demos etc.), but it is slow on real DVD videos. I.e. it works fast when there are small changes from Frame to frame.
FM Screen Capture Codec is a FREE software. Though this codec is a part of our ScreenVirtuoso software, you can download from our site and use it for FREE for as long as you like.
