How does changing a video speed works?

Video speed refers to the rate at which a sequence plays, determining how quickly or slowly the frames transition over time. It is often expressed as a factor relative to the video's original speed. The standard speed for most videos is 1x, meaning the clip plays at its recorded or captured speed.

Adjusting video speed involves either speeding up or slowing down the playback rate.

When you speed up a video in a video editor, more frames are displayed per second, resulting in a faster-paced sequence. Conversely, slowing down a video involves displaying fewer frames per second, creating a more leisurely or deliberate pace.

Basics of video speed adjustment

Setting the speed of a video involves manipulating its playback rate, and several technical aspects come into play during this process. Here are the key technical considerations:

Frame rate

Frame rate (FPS) determines the number of frames displayed each second. Adjusting speed impacts the fps: speeding up shortens it, and slowing down extends it.

Values

Speed adjustments are often expressed as percentages or multiplier values. For instance, 200% speed means the video plays twice as fast, while 50% indicates half-speed or slow motion.

Keyframes

Keyframes mark specific points in the timeline where speed changes occur. Video speed adjusters use interpolation within keyframes to create smooth transitions between different speeds.

Audio Synchronization

Adjusting video speed may affect the audio. Ensuring sound synchronization is crucial. Reputable editing tools maintain the alignment between video and audio tracks.

Understanding these basics empowers you to manipulate video speed effectively. Whether for correcting timing issues, or creating dynamic effects, mastering video speed adjustment is a valuable skill.
