FastCodec 1.0 beta

5 from 1 Reviews
FastCodec is a free, fast lossless video codec, able to take video captures with a simple compression algorithm.
FastCodec uses a simple and efficient compression method: each frame is compressed separately; the frames are divided into square block of 4 x 4 or 4 x8 pixels; each block is converted from RGB to YUV color space and enumerative coding is applied to every transformed block.

FastCodec offers you two types of compression: lossless and high quality lossy compression. In the first case, there is absolutely no difference between non coded and decoded movies. On the other hand, the lossy compression provided by FastCodec is visually lossless, because there is a very small difference between original and compressed files, and the human eye cannot see it.

Another feature of FastCodec is logging, which is recommended for debug purposes and not during real time video capturing because it can reduce the performance of the codec.

FastCodec offers support for the following input and output formats: YUY2, YUNV, V422, YUYV, YVYU, UYVY, Y422, UYNV, RGB24, and RGB32.

This codec is implemented as a VfW driver, and its FOURCC is FCKK.

FastCodec has a series of restrictions, though. In order to perform lossless compression, the frame width and height should be a multiple of 4, for lossy compression the frame height must be a multiple of 4 and the width must be a multiple of 8, and the RGB compressed data can only be decompressed to RGB. Furthermore, YUY2 compressed data can only be decompressed to YUY2.

FastCodec is a perfect solution for anyone looking to convert various input video files into DVD quality AVI files at a very fast speed. It allows you to choose between absolutely lossless compression and visually lossless conversion while saving disc space and not compromising on image quality at all.

Does what it says. Takes your video and about as fast as it can lightning slams it down into an .AVI at a terrible overhead. Nearly 5,200kbps for a 352x240 at 30fps.

Most DVDs save raw 720x480 30fps video at 4,800kbps so the compression of FC is lower than a DVD.

But if you are encoding from a DVD or some other volatile source like a live video, it's nice to have that final 2gb .AVI source to work with and there are no keyframes so every single frame is as clear and clean as it can get like the source forwards and backwards in VirtualDUB.

It's free too. No nasty tags appear anywhere on your video and the user interface is minimally minimalistic.

Visually Lossless or Absolutely Lossless.
Not much more than that.

I use visually lossless and obviously the end result video is DVD quality no matter how high the action gets.

Not really for archiving videos because of the tremendous overhead so you should stick with your DivX and XviDs for that stuff but very good if you want to get "hands on" the source video to compare compression algorithms from a FC .avi source.
