Narrative:

On approach to sfo we were cleared for a visibility to runway 28R at sfo. Traffic was reported and in sight for ry 28L. We went to tower and were cleared to land runway 28R. On short final the traffic for runway 28L xed over from the left to runway 28R in front of us and landed. We made a go around and were vectored back for visibility approach to runway 28L sfo. We notified tower when traffic xed over and we started our go around.
