Questions, answered
What frame rate should I use for the web?
30 fps is the safe default and what phones record. Use 24 for a cinematic feel, and 60 for gameplay or sport where fast motion needs to stay crisp.
Can I increase frame rate to make video smoother?
Not really. Raising the rate duplicates existing frames rather than creating new motion, so the result is the same smoothness in a larger file. Smoothness has to come from the original recording.
Why does my converted video judder?
Because the source and target rates do not divide evenly — 30 to 24, for example, means dropping frames unevenly. Converting between rates that are multiples of each other, such as 60 to 30, avoids it.
Does the audio stay in sync?
Yes. Only the picture cadence changes; the soundtrack keeps its original timing and stays aligned throughout.
Will lowering the frame rate reduce file size?
Yes, usually significantly — halving the frame rate roughly halves the number of frames to encode. It is a good lever when a clip has to fit a strict size cap.
