We have digital cameras in this generation but in old generation where there was film role, how did the film captured video in motion (not photo) on the top of it how did it record audio? Were these in the same equipment or different audio video equipment?

Film stock is, essentially, the same as photography stock, in which a light sensitive medium (film) is fed through an enclosed device (camera) at a certain speed and the amount of light (natural and/or artificial) gets recorded onto the film. That reel of film is broken up or sectioned into twenty four separate bits or ‘slices’ of film, for each second of captured motion. (I think the 24 frames per second is to do with how our eyes and brains process visual information). They become the individual frames. That’s the basics of how old cameras record visual information.
In older, and home film formats, sound could be captured within the camera, but it was poor quality. Generally, and especially for studio released films, sound is recorded separately from the camera, and/or dubbed in the studio in post production so the sound can be isolated so no unwanted sounds or noises that would have been recorded ‘live’ can be heard.
