Ani-ST
Ani-ST Strengths
- Produced incredibly small file sizes by storing rendering instructions (vectors) rather than raw raster frames, making it ideal for floppy disks
- The human-readable script format allowed advanced users to manually edit animation paths and parameters directly in a text editor
Limitations
- Completely obsolete and inherently tied to the hardware limitations of the Atari ST ecosystem
- The generic .scr and .str extensions conflict with dozens of other historical and modern formats, making file identification a major challenge
- Zero native support in modern operating systems, web browsers, or standard graphics software
GIF
GIF Strengths
- Universal support across all web browsers, operating systems, and messaging apps
- Supports basic frame-by-frame animation out of the box
- Lossless compression is highly effective for simple, flat-color graphics like logos or pixel art
Limitations
- Limited to 256 colors per frame, resulting in poor quality for complex gradients and photographs
- Animations produce massive file sizes compared to modern formats like MP4, WebP, or AVIF
- 1-bit transparency limits edge blending on non-uniform backgrounds
