Why it happens: Orientation metadata interpreted differently
Fix: Normalize orientation before final export
Why it happens: Unsupported codec/container combination
Fix: Use MP4 with broadly supported settings
Theory: Most size wins come from reducing dimensions before aggressive quality drops.
When to use: Lower width first for mobile/social contexts.
Common mistake: Reducing both resolution and quality too far in one pass.
Theory: Container and codec combinations influence compatibility and efficiency.
When to use: Use MP4 for broad compatibility and WebM when size is priority.
Common mistake: Choosing rare combinations unsupported by target apps.
Theory: Loop length and FPS dominate GIF size; frame selection drives thumbnail CTR.
When to use: Trim short loops and choose high-contrast frames.
Common mistake: Exporting long, high-FPS GIFs that exceed platform limits.
Theory: Encoding presets trade CPU time for compression efficiency.
When to use: Use faster presets when turnaround matters.
Common mistake: Using slow presets where deadline outweighs marginal savings.
