Problem
A high-frame-rate source is conformed to standard frame rate before repurposing, and the resulting cadence differs from a platform-native upload made from the original.
Solution
Root Cause / Diagnostic:
Inconsistently down-converting high-frame-rate media (e.g., 120 fps or 60 fps down to 24/30 fps) across different post-production tools leads to erratic shutter angle perception and frame pacing. If one export applies 3:2 pulldown while another platform ingestion engine applies motion interpolation, identical source clips display noticeable cadence and motion blur discrepancies.
Actionable Fix:
1. Standardize high-frame-rate conform settings inside your NLE clip attributes: set frame rate conform explicitly to target sequence FPS (e.g., 30 fps with 180° shutter emulation).
2. Apply motion blur synthesis (such as ReelSmart Motion Blur or Resolve Motion Blur) at a 0.5 shutter factor when dropping 60 fps footage into 24/30 fps timelines to prevent choppy staccato motion.
3. Perform side-by-side motion comparison in a dual-monitor QC setup to ensure cadence matches across all platform-specific render outputs.
Pro Tip:
When shooting high-frame-rate source footage intended for mixed standard and slow-motion repurposing, always maintain a 180-degree physical shutter angle (1/120s for 60fps) to ensure natural motion blur when conformed down.
