Frame interpolation refers to a technique of inserting additional frames into existing ones. The goal of this process is to improve the smoothness of motions. To enhance the viewing experience, video editors prefer adjusting frame interpolation online. It proves beneficial when the original video contains lower frame rates, leading to choppy playbacks.

Part IV.Proactive Solutions: How to Avoid Artifacts Before You Shoot
The best fix starts in production. Here’s how to capture "interpolation-friendly" footage:
Shoot at a Higher Shutter Speed: The standard 180-degree rule (shutter speed = 1/(2x frame rate)) creates natural motion blur. For interpolation, you want less blur. Double your shutter speed. If shooting 24fps, use 1/100s instead of 1/50s. Sharper source frames give the AI clearer data to work with, drastically reducing ghosting.
Use a Stable Shot: While modern AI can handle some shake, a tripod or gimbal shot provides cleaner, more predictable motion vectors than erratic handheld movement.
Maximize Resolution & Bitrate: Shoot in the highest resolution and codec you can (e.g., 4K ProRes). More visual information and less compression noise lead to better analysis.
Plan Your Motion: Be mindful of extremely fast, chaotic motion or scenes with high parallax if you know you'll be interpolating later.
FAQ
-
1. Does interpolating a 24/30 fps webcam to 60 fps help?
For simple talking-head streams, increasing resolution and bitrate usually brings a more noticeable improvement than interpolating to a higher frame rate. Interpolation becomes more useful when webcam footage is combined with fast-moving screen content, where judder is more apparent. -
2. For live streams, what frame rate should I aim for when using interpolation?
Most streaming platforms recommend 30 fps for general events and 60 fps for sports, concerts, or gaming where motion detail matters. Real-time interpolation adds latency and computational load, so many streamers prefer capturing and encoding directly at 30 or 60 fps instead of interpolating. -
3. Are there cases where interpolating 24 fps movies is okay?
Interpolation may be used for accessibility or select action-heavy scenes, but it is usually offered as an optional playback feature rather than baked into the final video. For web distribution of films and shorts, keeping the native 24 fps is generally the safest recommendation. -
4. Is it worth going beyond 60 fps (e.g., 90 or 120 fps) online?
Most major platforms cap effective playback at 60 fps or show limited benefit beyond it. Since many viewers’ displays refresh at 60–75 Hz, interpolating to 90 or 120 fps mainly makes sense for local playback or niche platforms that explicitly support high-refresh streaming.
