Running the latest IOS on an IPhone 15pro max. The two issues I keep getting are that even if you select a video, a previous converted video shows up in the window, and the other issue is when you hit the + button or select a video to convert, the video browser just gives you the entire video folder. It should lead to the menu that shows your separate folders. Especially if I move 20 videos from all over my library into one new folder… I’d like to be able to access that new folder to pull videos instead of navigating through my entire video folder which has thousands of videos. Other than those two big issues, the app does exactly what it says it does. Wonderful upscaling.

No change whatsoever.
The Real Angry D
I have now attempted to upscale some 31 videos. Not one has a perceptible change to the quality in any way. I have attempted HD, 4K, 8K, and 16K, although every attempt scale to 16K has met with an error “not enough pixel information.”It is clear that this app does not work. I have cancels the subscription and will be demanding a refund from the Apple Store.Edit: developer responded to another negative review by claiming the app does not “upscale”. Which is odd because it’s literally in the app description. Further, all support is in Russian. Do NOT BUY!

Not even trying to hate on the app but it litteraly doesn’t even upscale past 1080p whether it’s in my photos/files or any other social media app. I just don’t understand why it’s labeled to “upscale” to 4k when you select it and convert the video it shows no difference in quality once so ever
Minor fixes and improvements.
