What is Frame Rate? — Ultimate Guide to Frames Per Second Explained [Shot List, Ep. 8]

Summary by Krater

This video explains how different frame rates impact motion perception and how filmmakers use frame rates like 24fps, high frame rates, overcranking, and undercranking to achieve specific stylistic effects.

Answers: How do film frame rates affect motion and storytelling?

• frame rates
• motion perception
• slow motion
• fast motion
• overcranking
• underckranking
• step printing
• shutter speed
• capture rate
• presentation rate

What it concludes

• When images are shown fast enough, the brain blends individual frames into a single moving image through persistence of vision.
• 24 fps became the cinematic standard because it was fast enough for sound technology while saving film stock costs.
• Higher frame rates like 48 fps reduce motion blur and eye strain in 3D presentations, as seen in The Hobbit.
• Shooting at 120 fps creates a closer, hyper-real perspective, as utilized in Gemini Man.
• Low frame rates combined with a slow shutter speed create blurring and streaking known as step printing.
• High frame rates enable slow motion by recording more frames per second so motion appears smoother when played back at standard rates.
