Download now archive with both 32 and 64 bit variants of version 4.
This is the latest and fastest version. It can decode video made by versions 2, 3 and 4, encodes to format of v4.
It's a bugfix release, unfortunately version 3 had a problem in its algorithm leading to crashes on some rare input
videos. The bug is now fixed but it has caused a change in bitstream, so the new version produces a different stream
of compressed data, hence v3 cannot decode it properly. So it's a major change, hence the version increase.
Download now archive with both 32 and 64 bit variants of version 3.
It can decode video made by versions 2 and 3, encodes to format of v3. This is the one our web player currently supports.
(Until it's updated to v4)
In case you need it you can still download version 2. It can decode videos made with versions 1 and 2, encodes to v2.
It is slower than v3 but compression is a few percent stronger.
