Problem
A creator overwrites the source project with a vertical crop version, making later horizontal re-edits depend on a compromised timeline rather than the original master.
Solution
Root Cause / Diagnostic:
Destructive project manipulation occurs when an editor modifies sequence raster dimensions from 1920x1080 (16:9) to 1080x1920 (9:16) inside the original project file without branching. This destroys nested compositions, keyframed framing coordinates, and widescreen title layouts, corrupting the canonical master timeline.
Actionable Fix:
1. Establish a non-destructive workflow by duplicating sequences: create a dedicated timeline named SEQ_MAIN_16x9_MASTER and duplicate it as SEQ_REPURPOSE_9x16_DERIVATIVE.
2. Save repurposing projects into separate derivative .prproj or .drp project files using strict versioning (Show_Ep01_Master.prproj vs Show_Ep01_Repurpose_v1.prproj).
3. Set canonical master project files and archive storage to read-only permissions immediately upon final master sign-off to prevent accidental overwriting.
Pro Tip:
Utilize DaVinci Resolve’s Smart Reframe or Premiere Pro’s Auto Reframe inside a separate "Deliverables" sequence while keeping the original 4K/UHD master timeline completely locked and untouched.
