Movies as quasi-strobe images is interesting and differs. For about 2/3 of dogs they perceived television as separate flashing pictures and not smooth movement.
frequency at which dogs perceive multiple flashing pictures as movement and why many donuts can't watch tv
Dogs perceive flashing images as continuous movement at a higher frequency than humans due to their superior "flicker fusion frequency." While humans require about 16–20 frames per second (Hz) to see smooth motion, dogs need at least 70–80 Hz. This means older TVs and screens with lower refresh rates appear as flickering images to dogs, rather than seamless motion.
This difference arises because dogs' retinas are optimized for detecting motion and low light, with more rod cells than cone cells. These adaptations make them excellent at spotting fast-moving objects but less adept at perceiving fine detail or vibrant colors. Consequently, many dogs may not find TV engaging, as the images appear disjointed and lack accompanying sensory elements like smell. Modern high-refresh-rate TVs may partially overcome this issue for some dogs.
