such as a red and yellow colour may dither to create an orange colour

Dithering happens in GIFs when Photoshop attempts to simulate a colour that is not on the colour table.
Dithering happens in webpages when there is an a colour that is not 8bit]]> 2017-01-12 09:40:04 UTC https://padlet.com/richardsonconnor09/1udyoqf0pshl/wish/146726471 What does this mean in terms of image quality - Disadvantages https://padlet.com/richardsonconnor09/1udyoqf0pshl/wish/146726619 They have a limited color display of 256 colors per file. This is as the file format only supports an 8 bit per pixel. This results in the GIF having a 'blocky' look to it, along with a pixelated look to it.]]> 2017-01-12 09:40:35 UTC https://padlet.com/richardsonconnor09/1udyoqf0pshl/wish/146726619 Colour pallet that is supported jamie_conquest https://padlet.com/richardsonconnor09/1udyoqf0pshl/wish/146726720 The supported colour pallet for a GIF image only supports up to 256 colours which is an 8 bit colour depth. This meas that there are only 8 bits per each base colour (RGB). Overall this means that there is a limited number of colours that a gif image can have which will make the image look dull or even not as bright as it could be.]]> 2017-01-12 09:40:55 UTC https://padlet.com/richardsonconnor09/1udyoqf0pshl/wish/146726720 Disadvantage of using the GIF format- Can GIFs be opaque rather than transparent https://padlet.com/richardsonconnor09/1udyoqf0pshl/wish/146727733 The creator is able to have a background for the stage OR a transparent background. This file format doesn't support opacity. So when you create the GIF you have to have one or the other]]> 2017-01-12 09:45:46 UTC https://padlet.com/richardsonconnor09/1udyoqf0pshl/wish/146727733 How would you keep a GIF animation file size small? jamie_conquest https://padlet.com/richardsonconnor09/1udyoqf0pshl/wish/146728213
Trimming Animation
First of all you will need to open the video file with Photoshop or another editor. Most of the time you won't need the whole sequence for the GIF animation, so you can trim the video in the Timeline Panel. Turn on the Loop option and try to find a good place to trim your video.

Reducing Image Size
You can either reduce the image size from the Image menu or do it later in the Save for Web dialog box. The video layer will have to be turned into a Smart Object if you resize the image, but you don't have to worry about this, it won't effect our workflow at all.

Both of these are a disadvantage because it takes a little longer to produce and to finish.

dithering reduces how much it can be compressed]]> 2017-01-12 09:49:04 UTC https://padlet.com/richardsonconnor09/1udyoqf0pshl/wish/146728322 Stic/Animated? jamie_conquest https://padlet.com/richardsonconnor09/1udyoqf0pshl/wish/146729992 89A is the animated version
