key frame

(graphics)
A frame in an animated sequence of frames which was drawn or otherwise constructed directly by the user rather than generated automatically, e.g. by tweening.

Most existing approaches to key frame extraction [6]-[8], based on measuring the differences between the last selected frame and the remaining frames and extracting a subsequent key frame if the measured difference exceeds the given threshold, are typically sequential processes leading to unpredictable results.

For example, most templates add letterboxes to convert SD source material to 4:3 output, which is seldom the desired technique, and key frame settings always opt for key frames at scene changes only, whereas most producers use periodic key frames and key frames at scene changes (Figure 2).

Examining my newly encoded Flash files in Inlet Semaphore, I noticed that Rhozet's default parameters used a key frame setting of 30 and showed no "auto-key" frame feature and that the encoded files had some dropped frames.

Although the SI generated by interpolating has superior performance than that generated by extrapolating since the former can use the future information to generate SI, the extrapolation DVC is very desirable for low latency cases since the decoding process begins as soon as it receives the previous reconstructed frame without waiting for the arrival of the following reconstructed key frame.
