## Most critical reviews (3 lowest-rated)

### 1/5 — No sound, batch doesn’t work

*2026-07-27*

Exports without sound, batch exports the first uploaded file multiple times rather than each file. Garbage.

### 1/5 — No difference and no sound

*2026-07-25*

I tried to upscale a 10 second video and I saw absolutely no difference in it after it got “upscaled”, and there’s no way to make sure the volume stays. Why the hell does it remove all audio from the video?

### 1/5 — Did not enhance video, and removed sound

*2026-05-30*

I had a 16 minute video I was wanting to enhance. I bought this app thinking it would enhance the quality and sharpen it. The end result was a 4k video that looked exactly like the original, but the new version did not have any sound… so the video was the same and it had no audio. The app did not function as I was hoping. I’m glad it was only 1.99.
