A distinction between different camera softwares is how high frame rate video footage is stored, with more recent phones retaining both the image sensor's original output frame rate and audio, while earlier phones do not record audio and stretch the video so it be played back slowly at default speed. While the latter encoding method increases compatibility on older devices if the aim were to achieve a slow motion effect, the former method offers greater versatility for video editing, where slowed down portions of the footage can be freely selected by the user, and exported into a separate video. A rudimentary video editing software for this purpose is usually precluded. The video can optionally be played back at normal speed, acting as usual video.
