Compressor: How Long Will My Video Take To Compress?

Apple Compressor now uses optical flow technology that helps reduce encoding time for the video output formats supported by the program. Now, in terms of encoding speed, Compressor is among the fastest programs available. Still, there is no way to accurately predict how long a specific video file will take to encode on your computer. However, there are many factors that can affect the speed of the encoding process, and this article will address the major bottlenecks in encoding speeds.

Why Video Encoding Is Such a Lengthy Process

There are many steps that Compressor must take in order to encode a video file from one format to another. Although the compression ratio of different video formats varies considerably, all of them use some sort of algorithm or process to make video files fit to certain constraints in terms of file size. Before compressor can convert a video file to another format, it first must decrypt all of the data contained in the original source file.

However, before Compressor can do anything with the source file, it first must decompress the file and interpret all of the bits of data contained in the video itself. Because some video file formats pack data much tighter than others, this process may take only a few minutes or it could take several hours. Only after Compressor has successfully decompressed, decrypted and interpreted the source data, can it begin to export the video into the new format.

Primary video data factors that will affect the time needed to encode or convert a video file will be the length of the video, the aspect ratio, as well as audio and video quality settings. Generally speaking, the higher quality the video, the longer it will take to convert or encode.

Choosing Reasonable Encoding Settings

One of the easiest ways to decrease the amount of time to need it to convert or encode videos with Compressor is to simply choose reasonable output settings. Most new video editors choose the highest quality effects settings for their videos almost instinctively. However, depending upon the type of media that the video will be viewed on, the highest quality settings are seldom needed.

For instance, if you are uploading a video to sharing sites or webpage, you should never choose the 'Best Quality' settings in Compressor. These settings not only take a long time to encode with your video, they also create very large files that stream slowly and make it hard for many web users to view your video. Although many Web users today now have very have fast Internet connections, a large percentage of people that will watch your video may still have higher latency or slower Internet connections.

Newer Processors Do Help Speed Up Encoding

If you are experiencing considerably slowed encoding times with compressor, you may want to consider upgrading your computer. Today's newer processors are designed to handle multimedia tasks much faster than those made even three or four years ago. For example, quad core or eight core processors provide the benefit of acting like many individual processors. With the clustering ability of Apple Compressor, you can set up the program so that it emulates using multiple machines to encode your video project files. Faster multi core processors and more RAM memory will result in faster encoding times for your videos.
