- dreamcompiler 10y agoYep. Happens because the phase of the sampling grid changes on different frames, which effectively increases resolution.
- compsciphd 10y agothat's also why 1080i effective resolution is more than simply 540 lines of resolution (1080i for a sitcom has a higher effective resolution than 1080i watching a a sporting even, which is also why I think ESPN chose to transmit it 720p, at least for some time, as opposed to 1080i, but could be wrong about that)
