4:3 and 16:9 are only relevant to taking photos. The aspect ratio of the video is set by which record mode you set.
The point of my question is that if you're shooting photos in 4:3, and if you want to record video, you will have a zooming effect if you don't first switch the ratio to 16:9. The zooming effect at the start of video recording may mean you miss parts of what you actually want to record at the start. I know it's not hard to manually switch it to 16:9 prior to recording video, but you may not have time for that if you want to record something really quickly. So if you really want to shoot photos in 4:3, I think it's better to have the camera setting at 16:9 by default and switch it to 4:3 if you really want more field of view. 16:9 also has the advantages of displaying full screen on most people's commonly used devices (phone, TV, PC etc) without having to spend precious time editing it.
The aspect ratio you have the photos set at doesn't transfer when you start a video. The aspect ratio for video is set under settings in the camera. I normally have mine set at FHD 1920x1080. You are correct that this does have a zooming effect when recording. VGA doesn't zoom but you obviously lose image quality. To be honest I don't record much video on my phone. I'm a bit of gadget freak so I have multiple cameras/camcorders.
OK, you're going to have to tell us what these food/drink pictures are (Please)
