Video is of a Victorian Club Autocross Series event I recently did. Camera is mounted on the front left vertical bar of the roll cage. Picture quality is good however the noise of stones being thrown up under the car by my rally tyres tends to drown out much of the engine note. Melton is a pretty unforgiving track. Most of the tyres are at the edge of the track to cover large unyeilding volcanic rocks. The track surface is a mix of raw clay and volcanic stone which gives best grip when it is almost dry (with a slight moisture content.) If it rains the track is virtually undriveable.
