SharpenAI: V3 vs V2

Hi,

I have some questions about SharpenAI regarding the differences between V2 and V3:

Question 1)
Is it possible to somehow install V2 and V3 in parallel or run them alternatively under Windows 10?

I ask because I feel that the results with STABILIZE in V2 were better than those I get in V3 (see question 2).

Question 2)
Is “Motion Blur” from V3 equivalent to “Stabilize” from V2?
Why confuse the user with new terms here?

Question 3)
When will it finally be possible to see the native 1:1 resolution of the edited photo in SharpenAI on a 4K display with activated 150dpi Windows scaling display anyway? In Photoshop this works since several years.

Kind regards

Hmm, amazing that Topaz doesn’t seem to know the difference between Stabilize (AIS V2) and Motion Blur (AIS V3).

I think so too. Stabilize(v2) was better than Motion Blur(v3).
Also, I noticed that the result images of Motion Blur(v3) are shifted to bottom-right a little unreasonably, it was not in Stabilize(v2).

I quite enjoyed using V2 with some unexpectedly good results. V3 is like a disaster where only basic sharpen module gives acceptable results. Everything else causes halos, pixels shifts and Orton effect like look. It is so bad (basically useless) I would just go back to V2 in an instant if I found a way to do so.

Can´t one simply deinstall v3 and reinstall the latest V2?

I’d better ask before I start uninstalling V3.

Thanks

For this reason I will stay with version 2. The results with STABILIZE in version 2 are excellent. It’s not good when the software gets worse. I just advised friends not to buy Sharpen AI version 3.

I’m just surprised we still got no answer from the developers and not many more people are commenting here or elsewhere.

I hope this will be sorted in the next update; this should have never gone past an alpha build. It is much faster but that really doesn’t matter when results are abject failure.

Hi,

I also find it very regrettable that Topaz representatives do not also take a stand here when it comes to such important matters.

Obviously, they only respond to support tickets, which in my opinion is a big mistake, because potential customers do not see the answers to official support requests from existing customers, and by not responding on the part of those responsible in the forum, they may not buy SharpenAI.

Therefore, I take the liberty of pointing out at this point that after initiating a support ticket, the problems described above (pixel shifts, etc.) were confirmed to me and a bug fix was announced as soon as possible in one of the next updates.

I have at last managed to install V3 and V2 alongside each other. The key seems to be to get the FULL installer and not the online version, because that gives you the option of where to install the app and the resources it uses.

I started with an image where I was convinced that v2 was better, but on another image V3 seemed better, so because V3 clearly has advantages, notably speed and I like the interface better, I think I will start with that, keeping V2 in reserve for those images where V3 does not produce the results I want.

Of course, I should add that I was using it to retrieve a terribly blurred photo, and though the result looks a bit oversharpened with either V3 or V2, it is amazing what the software has been able to do. I still have not tried it on many images yet.

Am I right that if you use the masking tool, then the AI computes the corrections differently, based on just the area that is being done, and not on the whole image? If so, it would be interesting to find out whether if you have an image where only part of it is blurred (the back end of the bird is in focus, but its head is moving), is is possible to mask off the sharp bits of the bird, and have SAI correct the blurred bit? Maybe something to try at some point.
