TapeShift v1.3.1

Fast, safe MiniDV/Hi8 → ProRes transcoding for macOS.

TapeShift is a high‑performance Bash script for DV/MiniDV/Hi8 transcoding on macOS (tested on 15.5). It recursively scans for .dv/.avi and creates ProRes masters and ProRes proxies per source folder (PRORES/, PROXIES/).

What’s new in v1.3.1

• Interactive format prompt (MiniDV, Hi8, PAL) that sets appropriate color metadata.
• PAL selection will auto‑fallback to smpte170m if your FFmpeg build rejects bt470bg.

Features

• Parallel encodes with configurable --jobs and FFmpeg --threads
• Deinterlacing (yadif) and Resolve‑friendly folder structure
• Safe .mov.tmp writes and guarded rename
• Per‑file --timeout and FAT32 duration cap (-t 00:19:45)
• --retry, --dry-run, --overwrite, graceful Ctrl+C

Usage

chmod +x tapeshift.sh
./tapeshift.sh --timeout 3600 --jobs 8 --threads 2
# You’ll be prompted: MiniDV / Hi8 / PAL
# Or skip the prompt:
./tapeshift.sh --color-profile minidv
./tapeshift.sh --color-profile hi8
./tapeshift.sh --color-profile pal

Requirements

• macOS 15.5+
• FFmpeg (with prores_ks), e.g. brew install ffmpeg

Example Folder Structure

Before:

Footage/Scene1/file1.dv
Footage/Scene2/file2.avi

After:

Footage/Scene1/PRORES/file1.mov
Footage/Scene1/PROXIES/file1_proxy.mov
Footage/Scene2/PRORES/file2.mov
Footage/Scene2/PROXIES/file2_proxy.mov

Safety Notes

• TapeShift never overwrites source files.
• Always test with --dry-run first to preview actions.
• The --overwrite flag replaces existing transcodes.
• Temporary files are guarded and will only be deleted safely within PRORES/ or PROXIES/.
