What Video Frame Rates Should You Pick for Your Project?
I really enjoy Li’s work and even more so now that he’s sharing his hardly acquired knowledge. One of Li’s particularity is his capacity to mix pace in his editing, going from extra fast to extra slow with smoothness, keeping the viewer on the edge of her seat.
How does a one-man band handle picking the right video frame rate at the right time for the right sequence? That’s exactly what Li explains in the video below. From understanding what frame rate is to the context in which he’ll pick one frame rate rather than another.
Here is a quick summary but if you have an interest in the matter, watch the full video below, it’s packed with great tips and illustrations:
- 0 fps: for still images
- 1-15 fps: record with the intention of speeding the footage up in post and create a fast motion effect
- 24-25 fps: to record any subject that is going to be speaking or for landscapes with a lot of details and little motions to slow down in post
- 30 fps: can be used as a 80% slo-motion. Can add smoothness to a shot.
- 48-60 fps: “normal slow-motion”. To give more grace to subjects often when they’re laughing, clapping. Also good when filming people that are talking but you know you won’t hear what they say, the audience accepts that trick as signifying: it’s not the reality. Last but not least: used for shooting a music video, particularly singers singing. So when you bring the footage back at 24 or 25fps, the lips synch but the body moves slower.
- 90-120 fps: nearly stopped time effect thanks to Speed Ramp technique. To eliminate shake effect. The image at 120fps will likely be degraded, so to counter that, record your subject closer.
