  - Automatically corrects timestamps (`-fflags +genpts`)
  - Outputs to `~/Videos`
- `convert-multiple` command:
  - Merges multiple video inputs into one MP4
  - Re-encodes using same compression settings
  - Creates and cleans temporary file lists automatically
- Config system (`config/config.json`) with optional `jq` parsing
