Variable frame rate

Variable frame rate (even frame rate ) (Engl. Variable frame rate ) is a term from the field of video compression for a feature of many container formats is supported. It allows changing the frame rate when playing a video. In addition, the idea of a fixed frame rate can be completely ignored and a separate time code can be created for each image.

The variable frame rate is particularly useful when a video contains a large number of completely static images. In this case, the compression rate can be improved.

In addition, you can prevent the occurrence of artifacts during frame rate conversion when a video contains a combination of sections with 24/25/30/50/60 frames / second.
