What's New in Smoothie

1.6

September 25, 2026

• Faster Processing: The processing pipeline was rebuilt to move frames through upscaling and smoothing with fewer intermediate steps, so enhancements finish sooner. • Sharper AI Upscaling: Improved AI upscaling and Apple Vision blending keep fine detail crisp while avoiding the soft or over-sharpened look on demanding clips. • Portrait Videos Fixed: Vertical clips are no longer skipped during upscaling and now get exactly the same treatment as landscape footage. • Refreshed Interface: Cards, buttons, and progress panels were redesigned with a modern look that is easier to read at a glance. • Language Polish: More reliable language selection with correct regional variants, so the app always matches your preference.

Amazing

Smoothie is an impressive video enhancer for improving quality without sending your videos to the cloud. I like the 4K upscaling and 120FPS interpolation, especially for making older or choppy clips look smoother. The ProRes export and detailed before-and-after preview are also great for creators. The on-device processing is a big plus for privacy. 🎥🔥

Broken

The only feature that actually works is upload. Nothing changes when attempting to upscale videos.

Response from developer

Hi RG Life, Thank you for bringing this to our attention! We have identified a couple of bugs that might cause the upscale process to halt on certain video formats, which prevents the final output from being generated properly. We are actively working on a fix and will release an update very soon to resolve this. We appreciate your patience as we continue to improve Smoothie!
