A user interface system and method of recording/editing a video while applying special effects in real time. The interface can be associated with an electronic device including a processor in communication with a camera and a memory unit, or can receive previously prepared video. A first speed rate of the video can be changed by modifying a frame in the video data to create a different modified video data at a modified speed rate that. This allows for continuous recording and/or displaying of video at different speed rates without altering operations or settings. The interface can include time guidelines associated with selectable speed rates, to display which speed rate setting is near a touching finger or pointing device. The guidelines can be activated automatically or can change color, shape, intensity or other property based on finger location, and can aid in object positioning in a field-of-view.

Methods, systems, and media for generating a summarized video using frame rate modification are provided. In some embodiments, a method for editing a video is provided, the method comprising: receiving, using a hardware processor, a video file; identifying a plurality of frames at a playback frame rate from the video file; generating an edited video file by extracting a subset of the plurality of frames, wherein the extracted frames in the subset of the plurality of frames are separated by a predetermined length in the plurality of frames and wherein extracting the subset of the plurality frames modifies a frame rate of at least a portion of the video file to an effective frame rate; storing the edited video file; and presenting the edited video file at the playback frame rate.

Various embodiments of apparatus, systems and/or methods are described for independently controlling an audio stream relative to a video stream in audio trick mode. In one example, an audio stream and a video stream is received, where the audio stream comprises frames that correspond to corresponding frames of the video stream. The audio and video streams are played from a first time to a second time at a first speed. An input to time shift the audio stream independent of the video stream is received, and after receiving such, the audio stream is time shifted to the first time. Then, the audio stream may be re-played from the first time to the second time at a second speed different from the first speed.
