+    \question Lucy records using her camera. The camera saves the
+    audio and video parts of the recording seperately. Lucy transfers
+    recording to her computer. The audio file has a size of 12.8 kB.
+    Audio is recorded at a sample rate of 320 kB per second. The audio
+    resolution is 32 bits.
+
+    \begin{parts}
+
+        \part[5] In minutes, how many seconds was the recording.
+        \vspace{\stretch{1}}
+
+        \part[5] A video file consists of many still frames. Each
+        frame is a normal image. The size of a video file can
+        therefore be expressed as:
+
+        \begin{align*}
+            \mbox{Video file size} = \mbox{Number of frames} \times
+            \mbox{Size of each frame}
+        \end{align*}
+
+        If each frame is 1920 pixels wide and 1080 pixels high in
+        resolution, and the bit depth of 24 bits, what is the file
+        size of the video file.

+
+        \part[1] Lucy combines the audio and video to form a file. She
+        then runs a lossy compression algorithm on the resulting file.
+        What is lossy compression?
+        \vspace{\stretch{1}}
+
+        \part[3] The file size after compression is reduced by 20\%.
+        What is the final file size?
+        \vspace{\stretch{1}}
+
+        \part[1] State an assumption made for part (d).
