Sony ZV-E1

“In video you can't expect the mechanical shutter to fire 30 times a second, so it records with no shutter. Camera shutters are not fast enough, and it would be pretty loud if it did anyway. To shoot video if you want to avoid rolling shutter in video either shoot in crop apsc mode (60fps), use a slow shutter speed (to avoid light banding) or use a camera with a faster read out speed (ZVE1 FX3 etc).”
