Select this method if you are using the video in a streaming application where you want to control the streaming bandwidth rate. The quality is set by CRF (constant rate factor). This method allows you to set the max bitrate for given video quality. This is the default video compression method used. Increase the target size if you need better quality. To overcome this, start with a decent size (as a percentage of original), then test for video quality. The downside is you don’t know how the target size will affect video quality. The pros of this method are, you can achieve a certain target size.

For example, if you set it to 60% for a 1Gb file, we will attempt to make your compressed file size 600Mb or less. This method allows you to set a target file size for your video as a percentage of the original size. As a Percentage of the Original Size (Default) If you prefer a lower file size over encoding time, choose a slower preset. Choosing a slower preset allows better optimization (lower bitrate/file size) for a given video quality level. Preset: Presets refers to the video compression speed. Higher values mean more compression (reduced file size), lower values mean better quality (but bigger file size). For the H264 encoder, possible CRF values range from 0 to 51. To do that, it uses different compression levels on different frames.

By Video QualityĬRF (Constant Rate Factor): CRF method attempts to keep a constant perceived video quality. We provide 4 settings related to both methods. You can either optimize the bitrate or resize the video to a smaller size.
Xvid decompressor windows#
As for those designed to compress different video contents, the most famous, but also the most commonly used are certainly DivX, QuickTime, and Real Video, and there are also XviD, Windows Media Video and many others.ĭepending on the performance of the device itself, it is also defined which exact audio or video codec will be used on that occasion to encode or decode certain audio or video contents.There are two main methods to compress a video.

The most known codec used to compress different audio contents is quite surely MP3, and there is also Windows Media Studio, as well as AC3, then Real Audio, AAC and others. Of course, there is a possibility to compress, which will not result in loss of quality, although it also has some disadvantages as it is considered significantly less efficient than the former. However, in this case, there is a certain type of defects, as in fact, the quality of the audio content itself deteriorates to a certain extent, and certainly, it can never again return to the state it originally had. However, it seems that storing audio materials is simpler, as they can be reduced, that is, compressed into a popular MP3 format, which reduces the amount of memory they actually take up by more than 5 times. To provide a detailed clarification of the above, we will give a simple example: if you have certain video content, the size of which is 720x576 pixels, and the transfer rate is 256 megabytes per second, it can be calculated that it takes over 180 gigabytes of memory for just 2 hours of that kind of video. It is for this purpose that we use the codec. That the need for such types of contents to be in a way reduced to take as little space as possible is fully expected. It is well known that any audio or video content requires a significant amount of computer memory if it is to be saved, so that is why it often happens that there is no possibility that such quantity is actually stored in the media available, primarily those portable, but it is also almost impossible for specific contents to be transmitted over certain network resources in an optimally acceptable time frame. The term, in fact, originates from the abbreviation for coder-decoder, that is, compressor-decompressor.
Xvid decompressor software#
A specific type of hardware device that is primarily intended for signal coding, both video, and audio, on a particular software module that has the same function is called codec.
