What is a filter?

A filter is a graphic overlay that can be uploaded to your Slate account to put on top of any image or video. They can be either static or animated. Filters lock in creative, so are easy to plug in and export for quick content wins.

Sizes & File Types

Filters are .png or .mov files with an alpha channel that are used as overlays. They can be applied on top of content in Slate and can be created in any of the four dimensions supported in Slate (9:16, 1:1, 4:5, 16:9). Png filters should be no larger than 1920px in height or width, and should be under 8mb and under 72 dpi. Animated filters can be created as .mov files. Refer to the animated filters article for more info on creating this type of asset.

Filters must be exported in the following dimensions for each ratio:

9:16 = 1080 x 1920

1:1 = 1500 x 1500

4:5 = 1200 x 1500

16:9 = 1920 x 1080

Q: Can I upload custom sized filters?

 A: No. Although you can create in a custom workspace on web, filters and templates are only supported in the sizes listed above (9:16, 1:1, 4:5, or 16:9).

Q: Can I control layering in the mobile app?

A: No, you don't have the ability to send things forward or back, and assets lay as they were designed. Therefore, filters will always be on top of media. 

Q: Can I change out the colors, graphics, or font type used in a filter?

A: No, filters are locked for consistency and to maintain brand look. You can add in unique media with each element, but can't change aspects designed in the filter.
