Bug with save

ananizarta

Hello, there was such a problem when saving a gif file, for example, the file weighs 100mb and at the output I get 50mb and the gif does not work correctly

I can't tell from your image what is wrong. It's not unusual for GIF to have artifacts because a GIF can only have 256 colors in each frame of the animation.

You said the GIF does not work correctly, does that mean it doesn't play, for example in a browser?

GIF may not be a good file format for your export. GIF files have limited colors and are not usually so large, usually they are for short animations.

well , how to say at the beginning of the animation everything is fine during the animation , such points appear throughout the animation and when it comes to an end everything is fine , in sequence or in video format everything is fine

Many techniques, collectively called dithering, have been developed to approximate a wider range of colors with a small color palette by using pixels of two or more colors to approximate in-between colors. These techniques sacrifice spatial resolution to approximate deeper color resolution. While not part of the GIF specification, dithering can be used in images subsequently encoded as GIF images.

Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images.

Photoshop has a few GIF settings Spine doesn't: diffusion/pattern/noise dither, web snapping colors, interlaced, lossy output, and some options for how colors are reduced. :nerd:

- Gif looks very jaggy?

Thanks SilverStraw!

This isn't true anymore. Now Spine has GIF settings that Photoshop doesn't! 🙂

See the Wikipedia article on dithering that SilverStraw linked. The artifacts you see come from GIF only having 256 colors. You probably want to use a different format, like AWEBP.

Yes, I see it now.
