Problem
A creator exports at an unusual resolution that a platform scales twice before delivery, softening graphics more than a correctly sized master would.
Solution
Root Cause / Diagnostic:
Exporting non-standard resolutions (e.g., 1152x2048, 1080x2160, or arbitrary phone screen capture dimensions) forces video platform CDNs to execute non-integer bicubic resampling to fit native delivery buckets (1080x1920 or 720x1280). This dual-stage scaling introduces phase shifting, anti-aliasing blur, and softened graphic edges that degrade perceptual resolution.
Actionable Fix:
1. Lock timeline sequence settings and render dimensions strictly to standard 1080x1920 pixels (exact 9:16 aspect ratio, square pixels 1.0 PAR).
2. Scale any non-standard screen captures or custom camera rasters within the NLE canvas to fill 1080x1920 using Lanczos or Bicubic sharper filtering before export.
3. Check exported video properties in MediaInfo to verify dimensions read exactly 1080 width by 1920 height prior to uploading.
Pro Tip:
Never trust mobile app in-line video uploaders to intelligently crop or scale non-standard aspect ratios; feeding the exact native display canvas (1080x1920) bypasses server-side rescaling algorithms completely.
