Does lowering the frame rate reduce file size?

Yes, fewer frames per second means less data and a smaller file. The reduction is roughly proportional to the FPS decrease. All processing runs on your self-hosted SnapOtter server.

Will changing FPS affect audio sync?

No, the audio track is adjusted to maintain perfect synchronization with the new frame rate. Both audio and video timelines stay aligned. Processing happens entirely on your local server.

Can I use this to create slow-motion effects?

Reducing FPS can create a choppy slow-motion look. For smooth slow motion, dedicated slow-motion tools with frame interpolation are better suited. This tool focuses on frame rate conversion for delivery standards, all processed locally.
