Basic features

• Lottie doesn’t support GIFs
• Lottie doesn’t support Videos
• Image resizing doesn’t make the image “fit” perfectly
• Layer with negative sizes are not supported in Lottie. So are operations with negative sizes

Animation features

• Text scale from center doesn’t scale from the center of the text layer
• Mask presets spawn a fixed size mask (i.e. stroke gets reduced to layer dimensions)
• Resize in Jitter moves the anchor point but it won’t in Lottie, it might be surprising

Complex construction

• Mask group with rotate or scale and the masking layer moving / resizing
• Text in SVGs are not converted to Lottie shapes
