How changing resolution affects file size and clarity. Scale your videos for web and mobile.
If you are sharing a 4K video for WhatsApp, it's a waste of bandwidth. Scaling down to 720p or even 480p can reduce file size by up to 90% without losing much clarity on small screens.
Shrinkify automatically calculates the height (maintaining aspect ratio) if you only provide the Width. This ensures your video doesn't look 'stretched' or 'squashed'.

Why it happens: Uploading oversized files for small containers wastes bandwidth.
Fix: Match output dimensions to target container size.
Why it happens: Downscaling too aggressively can make text and details unreadable.
Fix: Keep aspect ratio consistent to avoid distortion.
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.
