Original GitHub issue: https://github.com/NickeManarin/ScreenToGif/issues/556

Screen To Gif: 2.19.3
Encoder: Gifski
Platform: Windows 10 1703 x64

---

Problem

Gifski generates frames for even static recordings, results in duplicated frames and redundant file size

---

Demo generated from same project

Recording by gifski-quality 100 (frames: 81, file size: 5.91MB)

Gif link if github said it's too large

Gifski-quality 100 zoom in. Note the flickering pixels.

Recording by 1.0-quality 1 (frames: 19, file size: 1.97MB)

1.0-quality 1 zoom in. Unchanged pixels stay the same thus it's basically 1 frame with a long timeout

Have you tried to use the test version, available here #551 ? This test version uses the latest version of Gifski.
(Remember to delete the old Gifski.dll and download the new one via Options > Extras)

Because this looks like something that I have no control over it. It's something that Gifski controls it.

Played with ScreenToGif.2.20.Preview.3, but can't download the latest gifski, check the error log at the end of this comment.

Tested with the gifski.dll from 2.19.3, it has the same problem.

Do you have .NET Framework 4.8 installed?

uhh, no?

Anyway, kornelski said

This is done on purpose as temporal dithering.

So I suppose the solution is Don't Use Gifski for Static Frames™

ScreenToGif v2.20 requires .NET Framework 4.8, so if you have an older version installed, some features may be broken. I'll add a message explaining that.

Anyway, kornelski said

Ohh, ok. Btw, the version of Gifski that you are using is 0.8.5.
The newer version that you tried to download is 0.9.3.
