Why are photos such better resolution than videos? Because in videos each frame is compressed differently, and typically far more aggressively than single photos. In video coding, the first frame, and say, every 16-th frame are compressed like a high-quality photo. We call them Intra or I-frames. These are the frames with the highest quality.
Why is video quality worse than photo? Much of the difference is due to higher compression for video. For example, my DSLR has a 24 megapixel sensor. The raw data from the sensor is probably 14 bits per pixel, one colour measured at each pixel. This would take up 48 MB of space on the memory card without any compression.
Why are photos better than videos? Photos grab attention and load quickly. They’re an essential addition to written content and enhance the user experience. They may not be as dynamic as videos, but they are far more practical, not to mention easier to find or create.
Why do video cameras have less megapixels? Re: why do some 4K cameras have less megapixels than non 4K cameras? Video recording relies more on processing speed than big sensors for higher resolution (still photography). Cameras that designed for sports photography with high burst rates tend to have smaller sensors too and are designed for speed.
