GigaPixel or Video Enhance AI

Brandigan · September 8, 2020, 4:47pm

Hi, first post here. Trying to work out best place to post my various findings as only been playing for a month with SAI, GAI and VEAI (briefly), and I guess this is where I start: I just like to add that I hope that whatever engine VEAI uses is added as an option to GAI, rather than a replacement. In my very limited testing with VEAI - attempted to see if it was just easier than batch processing images through GAI (twice, because… it does have its own issues) - the results were not even close in noise reduction and clarity on any of the engines. i.e. GAI was the clear(!) winner. Only IMO, of course.

I’m going to make my first post here also, to add that Gigapixel seems to have much more robust detail resolution than any of the options in VEAI. I would actually love to see Giga’s engine available in VEAI.

taylor.bishop:

When using Lightroom to bring the images in, all it is doing is calling Gigapixel with the file paths as a command line argument. It is the same as opening up a command window / terminal and putting this in (Mac will look different but is the same thing):
"Topaz Gigapixel AI.exe" C:/path/to/file1.jpg C:/path/to/file2.jpg C:/path/to/file3.jpg
The slowdown you’re seeing when dragging a folder in is the time it takes for Gigapixel to scan the dragged-in-folder and collect the file paths. It does this for each subfolder too, so if you have folders inside of the folder you dragged in it’ll take longer.

The processing slowdown you’re seeing is a different matter, however. Saving over the original image is quicker than creating a new file and writing the processed image to it. There’s a lot of reading / writing that has to happen when duplicating the image that doesn’t happen when saving over the original image.

Using lightroom classic 8.4.1 in Win10 x64
I imported >11000 tiff images in lightroom.
Gigapixel only received 9000+ images. (Buggy, but I can work with it).
I believe the files not sent to Gigapixel where on a second page, not selected in Lightroom.

You may need to leave pc for some period 5-10 min between call operations.

It can also help to open and setup Gigapixel with folder images and settings, close program and then call with lightroom.

Processing speed is good, through lightroom “saving over original” through short path.

So, I suspect that lightroom also controls the location and save over image data?

Can someone make command prompt template for opening/saving images in fixed location.
I have been using settings x2, 55, 50 in Gigapixel.

Topaz Gigapixel AI.exe
-i C:\a\a00001.tif C:\a\a00002.tif ETC.
-s 2
–suppress-noise 55 ???
–remove-blur 50 ???
-o C:\a
-f 16tif
[Press enter]

TEST RESULTS: The cmd window did not accept Topaz flags with Gigapixel.
