My understanding is that the video codecs are pretty clearly ahead for lossy compression, even for small numbers of frames. Image codecs got stuck in the jpg/gif/png local maximum, hence why a lot of the new image codecs (webp, heif, avif) are conceptually "one frame of a video codec" (vp9, h265 and av1 respectively)
