Learn everything you need to know about Frame

A frame is a static image that forms the sequence of a video. When it is played together with the rest of the frames, it creates the movement that viewers can observe in the fragment. We can identify two main types of frames:

  1. Analog frames. They come from a film, and they are physical frames, generating the movement by passing through a projector.
  2. Digital frames. Through a software that incorporates a codec, these are encoded to generate digital videos. A digital frame can be a transformation of other existing frames, or a complete image.

On the other hand, it is also important to know the frame categories most commonly used by the main video codecs:

  • Predictive coded images (B-Frames). They allow splitting frames into several chunks, or displaying previous and future frame changes.
  • Intra-coded images (I-Frames). Complete images, similar to a PNG.
  • Predictive coded images (P-Frames). Displays, exclusively, the relative changes produced in previous frames.
