What i always do is to see the movie and take the captures as i see it, so just like Garco says at then end of the movie i can choose from all the angles ive taken for a car which one's the best to submit as main picture, today for example i did it by submitting the car as it was appearing in the movie, but it takes longer because you add the car at the first place and seconds later you see that there's a better angle so you have to change it again and change the time tags again, its not comfortable to do, that's why ive never done it though that this doesnt mean that i dont think that it is a good idea, which it is...
