Huffyuv

If you are a computer expert and you like to tinker with the settings of multimedia formats, then you most likely realized by now that, if used correctly, some formats and codecs can help you save HDD space, due to compression.
Huffyuv is a lossless video codec, which means that you will not notice any difference between the output stream, as generated after decompression, and the source file.
In other words, the two tracks will be bit-by-bit identical so that you do not need to worry about the quality being affected.
You can use Huffyuv to replace uncompressed YUV as your default video capture format, since it provides you with increased performance. You can easily install it by right-clicking the *.inf file and selecting the Install option.
More precisely, it can be used to compress a full-resolution video (720 x 480 x 30fps) in real-time, while it is being captured on your computer. Considering it also supports lossless compression of RGB data, you can use Huffyuv for the output streams created by specialized applications such as VirtualDub.
However, if you decide to use this codec for video capture, you first need to make sure your card is able to capture in YUY2, UYVY, or RGB formats - most of them support at least one of these formats, yet if yours does not, you can only use Huffyuv for editing (not capture).
On the downside, this codec is most efficient when used on older operating systems, as it has not been tested on newer OSes since it has not been updated in a very long time.System requirementsSSE capable CPU
