Learn how to choose a clip, set 4K and smoother motion, follow processing, compare the before/after detail, and save the finished video.
Smoothie keeps the path simple: select a video, choose how far to enhance it, wait for processing, then inspect and share the result.
Open Smoothie and choose a clip from Photos or import one from Files. The app shows a quick start guide so the first run is easy to follow.
Smoothie shows the original resolution, frame rate, codec, bitrate, and file size. Use this screen to decide whether you need sharper detail, smoother motion, or both.
Choose the output resolution and frame rate that fit your clip. 4K improves visible detail, while 60FPS or 120FPS makes motion feel smoother.
Fast is better for quick, reliable results. Quality is a good middle path. Pro is for the highest output quality when file size and processing time matter less. Prefer AppleVision enables Apple's GPU-powered upscaling engine when your device supports it.
Tap Start Processing and keep Smoothie open while the progress panel runs. Longer, higher-resolution, or higher-quality exports can take more time.
Use the detailed comparison to see what changed. Check edges, textures, and motion-heavy parts so you can decide whether the video is ready to share.
When processing is finished, review the final preview. If it looks right, tap Save / Share to keep the video or send it to Photos, Files, messages, social apps, or your editing workflow.
