TrickFlipper

Batch mirror videos horizontally for ML data augmentation. Designed for flipping LCORK7 (left-cork) videos to RCORK7 (right-cork) with sequential TRICK numbering.

Requirements

• Python 3
• ffmpeg (brew install ffmpeg on macOS)

Usage

Place the script in your input directory (e.g. LCORK7/) and run:

# Dry-run: verify mapping without processing
python mirror_lcork7_batch.py --dry-run

# Process videos (skips existing output files)
python mirror_lcork7_batch.py

# Overwrite existing output files
python mirror_lcork7_batch.py --overwrite

Options

Flag	Default	Description
--input-dir	script directory	Input directory
--output-dir	../RCORK7	Output directory
--start-index	57	Starting TRICK number
--pad	3	Zero-padding digits
--dry-run	—	Print mapping, do not process
--overwrite	—	Overwrite existing output files

Example

Input: TRICK23_LCORK7.mov, TRICK24_LCORK7.mov, …
Output: TRICK057_RCORK7.mov, TRICK058_RCORK7.mov, …

Files are processed in lexicographic order.
