SSR to 320×192 with (cid:15)-prediction

SSR to 320×192 with v-prediction

Figure 12: Comparison between (cid:15)-prediction (middle row) and v-prediction (bottom row) for a
8×80×48→8×320×192 spatial super-resolution architecture at 200k training steps. The frames
from the (cid:15)-prediction model are generally worse, suffering from unnatural global color shifts across
frames. The frames from the v-prediction model do not and are more consistent.
