The same prepared film excerpt, shown side by side at equal playback speed. Press play, then inspect the source and raw app export yourself.

Prepared, compressed 360p source versus Natural 4× output from Local Video Upscaler 1.0.1 (6), processed in desktop iOS Simulator. This is an existing app export, not a physical-phone timing test.

What you are watching

The comparison presentation shows an excerpt from Tears of Steel by the Blender Foundation. The prepared source and actual saved export play at the same speed. It demonstrates the look of this particular export; it cannot establish quality, audio behavior or processing speed for every source or device.

The prepared source is 864 × 360 coded pixels (863 × 360 as displayed by the app). The saved export is 3452 × 1440. The comparison uses the previously exported eight-second, 192-frame sample. The source and raw export linked below are a separate, earlier four-second excerpt (96 frames at 24 fps) from the same film. The eleven-second comparison presentation adds labels, a close-up and a closing card; it is not the raw downloadable export.

Before you choose an upscaler

Compare the same instant at equal display size. Watch texture stability, faces and edges. This SDR example does not demonstrate preservation of HDR; the app exports HDR sources as SDR.
