The libcamera-vid command has no 'forced' or fixed exposure or gain settings so the default automatic exposure control (AEC) has settled on a combination of gain and exposure that results in a well-exposed image.
The libcamera-still command has 'forced' a short exposure time of 1000 microseconds and a low gain of 1.0 which combine to less than the ideal exposure setting, leading to the noisy image. Removing the fixed settings to allow the AEC to find the optimum combination, or selecting a suitably long exposure time should lead to a better result.
