You'll face several problems when upgrading your old home movies to modern
technology—here are some fixes:
Problem: Movies have a different horizontal and vertical ratio than videos.
Solution: Choose "letterbox format," which professional filmmakers use to show the entire visible frame. Or cut a little on each side of the frame without affecting the story.
Problem: Because movies are recorded at 24 frames per second (FPS) and video is recorded at 30 FPS, the difference in frame rate causes the image to flicker.
Solution: To compensate, professionals use a special movie projector, which runs at 24 FPS but has a modified shutter that reduces the flicker. If your video camera has the option to change shutter speed, experiment with different speed settings and choose the speed that causes the least flicker.
