A low compression rate results in better image quality, but also requires more storage space. The compression rate reflects the ratio between the original amount of data and the reduced amount of data. This means that reducing the bitrate compresses your video. The more information available, the better the video image – but also the more processing power required for playback. If you lower this value further, however, there's a risk that movement on screen will no longer look as smooth and your video might become choppy.īitrate refers to the amount of information a video player or video editing program needs to process in order to play back a video. So if a video file created using a camcorder was filmed at over 25 fps, it's best to lower the fps value to 25 for the purposes of video compression. To keep the file as small as possible, you can adjust the high frame rate. But if you want to add slow motion during video editing, for instance, you'll be glad of this higher fps rate used for recording, since your video will appear smooth even if the playback speed is reduced by half. That's a much higher rate than you actually need.

However, many modern recording devices produce video files at a much higher frame rate, such as 60 frames per second (fps). In Europe, 25 frames per second are standard ('PAL'). The frame rate defines the number of images displayed per second.

This combination of file format and codecs ensures high video quality and a small file size, and it is currently supported by almost all hardware and software players.Ī video works just like a flipbook, by displaying many still images one after the other extremely quickly to create the impression of fluid movement.

Which file format should you choose? If you want to be able to play a compressed video file on many different devices, we recommend MP4 files with H.265 or H.264 for the video data and AAC or MP3 for the audio. This means that with container formats like MP4 or AVI, you don't know exactly what data is included. For example, an MP4 file can contain video data with the codecs H.265, H.264 or even MPEG-2 and even MPEG-1, as well as image data with the codecs JPG and PNG and audio with the codecs MPEG-4 Part 3, AAC, MP3, MP2 and MP1. Many of these file formats are known as containers, because they contain data that can be packaged in various ways. This reason for this is that while there are thousands of file formats, there are only a few compression methods. Since most file formats use the same compression methods, however, there aren't a ton of technical differences. Every software or hardware manufacturer develops their own file format – that's why there are so many different video formats and file extensions available. Anyone who edits videos using a computer has to work with different video formats – from older formats such as AVI and MPG or newer MP4 files to WMV, AVI, MOV, FLV, MKV and a thousand other file extensions.
