An ultrasound imaging system and method of ultrasound imaging. The method includes initiating a live ultrasound scanning session and saving a first sequence of images in a volatile memory. The method includes receiving a store command while in a retrospective image capture mode during the live ultrasound scanning session. The method includes detecting that the first sequence of images does not meet a length threshold and automatically continuing to acquire a second sequence of images. The method includes detecting that the combination of the first sequence of images and the second sequence of images meets or exceeds the length threshold and saving a third sequence of images as a cineloop in a non-volatile memory, the third sequence of images including both at least a portion of the first sequence of images and at least a portion of the second sequence of images.
